H. Public Hearing and First Reading of Ordinance No. 156, 2018, Amending Chapter 5, Article IV, of the Code
of the City of Fort Collins for the Purpose of Repealing the 2015 International Fuel Gas and Adopting the
2018 International Fuel Gas Code, with Amendments.
The purpose of this item is to adopt the most up-to-date, comprehensive, and fully integrated body of codes,
the 2018 International Codes (2018 I-Codes), regulating building construction and systems using prescriptive
and performance-related provisions. The purpose of these codes is to establish the minimum construction
Agenda Item 10
Item # 10 Page 2
requirements to safeguard the public health, safety and general welfare by regulating structural strength and
stability, sanitation, light and ventilation, energy conservation, and property protection from hazards attributed
to the built environment within the City of Fort Collins. With factoring in local amendment costs, it is estimated
the overall cost increase to build under the 2018 codes is less than 1%.
These amendments will go into effect January 1, 2019.
Because this is the first time the City is adopting the International Existing Building Code (IEBC) and
International Pool and Spa Code (IPSC) all language being added to the City Code must be shown as yellow.
Language that is being added as local amendment is highlighted in grey so that it is easily distinguishable from
already-existing language in the IEBC and IPSC.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinances on First Reading.
BACKGROUND / DISCUSSION
Since 1924 the City of Fort Collins has periodically reviewed, amended, and adopted the latest nationally
recognized building standards available for the times. The City has updated the minimum construction
standards fifteen (15) times since 1924.
The 2018 International Codes will replace the 2015 editions of the IBC, IRC, IMC, IFGC, and the IECC which
were adopted on July 17, 2017. Even though the 2015 codes were adopted not long ago, this 2018 code
adoption is important for the following reasons:
• Maintain the highest ISO insurance rating which affects homeowner insurance rates in our community. The
best score is achieved by adopting the most recent series of codes within 12 months of issuance.
• Many other communities in the area and Larimer County will be adopting the 2018 codes in early 2019 and
this will provide consistency and maintain regulations in the region.
• The 2015 City of Fort Collins Energy Policy has committed to adopting the newest IECC energy code
within 12 months of issuance.
• Adopting each 3-year code cycle typically means code changes are in small steps instead of large, costly
ones.
Some code provisions formally located within the above listed codes have been relocated into new separate
codes such as the IEBC and the ISPSC. These are included in this proposed adoption process; however, the
requirements in these two standards have not changed from the previous code sections located in IBC and
IRC.
Building codes and standards are reviewed and voted on by code officials and construction industry
professionals from across the country and published every three years under the oversight of the International
Code Council (ICC). These core 2018 I-Codes represent the latest construction publications from ICC.
Review process
The implementation of new building standards can have a dramatic impact on the construction industry and the
economy of the community. To better understand these impacts, a code review committee is convened (see
attachment #1) for the purpose of reviewing the new codes and all local amendments. The code review
committee represents a wide spectrum of volunteers from across the local construction industry including
private developers, residential and commercial builders, architects, engineers, representatives from the energy
conservation sector and Poudre Fire Authority.
The code review committee met regularly in July, August, and September 2018 to discuss new proposed
amendments and current amendments. In September, the code review committee found that the proposed
Agenda Item 10
Item # 10 Page 3
amendments are neither controversial nor overly onerous or cost prohibitive on the construction industry and
voted to support and moved for adoption of the 2018 I-Codes and amendments. While this review process
requires considerable time and resources, it produces enforceable and effective building codes and
amendments that the community and construction industry support and create together.
Changes in the new 2018 codes
There are a few dozen changes in the 2018 codes, but they are considered minor or only adding clarity. The
committee did identify one change worth noting:
The energy code window u-value will change from .32 to .30. This increase in efficiency has an approximate
cost increase of 8% for vinyl windows. This will add an upfront cost of $200-$300 to the cost of the window
package for an average size house but could reduce ongoing energy costs over the lifetime of the home. While
the ROI is small with this step, the Energy Board agrees any increase in efficiency is the right direction.
Local Amendments overview
Local amendments are changes to the proposed code or new code regulations that are added due to
life/safety concerns or from local priorities. Many of the current local amendments are now incorporated into
the new 2018 code as written (the International body of codes have caught up to many of Fort Collins local
amendments). As a result, several amendments have been removed, as they are no longer necessary. Other
amendments that did not have the intended results or were shown to be ineffective and an unnecessary cost
burden to the construction industry were modified or removed. Being mindful of the City’s Climate Action Plan,
any removal of amendments was done without forsaking gains in energy efficiency. Overall the changes from
the 2015 codes to the 2018 codes are few and impacts to cost of construction are minimal.
A handful of new local amendments are being proposed:
• The definition of Imminent Danger has been revised to add clarity and convey the urgency involved in
taking action. The language “at any time” has been changed to “immediate”.
• When a trash chute is provided in new multi-family buildings, a second chute for recycling must be
provided. This can be achieved in the same fire-rated shaft to reduce costs. Cost increase is approx.
$1500 per floor.
• In new multi-family, 10% of all parking spaces must provide an empty conduit from the electrical room to
the front of the parking space for the purpose installing electric vehicle charging equipment in the future.
Approximate cost increase is $300 per parking space.
• A new, no-fee emergency repair permit provision was added to allow a fast permit to be issued in a
disaster/damage situation where a building owner can temporarily repair a dwelling and obtain inspection
to allow occupancy while more permanent repairs are forthcoming. This was recommended by the Larimer
County Building Department, who scrambled to put this in place after several recent disasters.
• Responding to a concern by the Chamber of Commerce, the requirement to install a fire-sprinkler system
in an in-home daycare (5 children max) has been removed. In-home daycares are not required to change
the building occupancy (remains single-family) and these are state regulated. Neither the City nor Poudre
Fire Authority is notified of these. If that requirement changes, requiring these owners to fire-sprinkler could
have a large negative effect on the number of these businesses approved in Fort Collins due to the high
cost of these sprinkler systems. PFA supports this change.
• All structures choosing to install asphalt shingles will be required to use class 4 impact resistant shingles.
A requirement for reroof projects to report the amount of waste and final waste location will be added, as
well. The cost increase for an average size home to install Class 4 shingles is $500 - $1000, or 5%-10%
increase over normal shingles.
• Responding to a concern by the Water Board about water consumption, showerheads will be lowered from
2.0 gallons per minute (gpm) to 1.8 gpm. In addition, the flushing performance requirements of new water
closets will increase which should reduce multiple/failed flushes. Research conducted by water
conservation staff did not identify any substantial costs increases.
• Responding to a concern by the Commission on accessibility, the required roll-in showers provided in new
multi-family and hotels, will be larger, from 30”x60” to 36”x60”. The impact (approx. $100 per shower) is
Agenda Item 10
Item # 10 Page 4
minimal since those size shower pans are readily available and most projects only require one to four roll-
in showers depending on the number of dwelling units/sleeping units.
The cost assumptions discussed in each bullet above were calculated based on outreach to professionals in
the building industry, such as general contractors, electricians, plumbers, mechanical contractors, and fire-
suppression contractors. Construction supply houses were contacted for an estimate of off-the-shelf materials.
Factoring in local amendment costs listed above, it is estimated the overall cost increase to build under the
2018 codes is less than 1%.
CITY FINANCIAL IMPACTS
Alterations to, or new construction of City-owned properties must comply with the provisions of the 2018 I-
Codes. The scope of work will determine the financial impact to the City. In general, there are no Citywide
financial impacts expected with the adoption of the 2018 I-Codes.
Community Development and Neighborhood Services (CDNS) anticipates the following financial impacts which
are accommodated by the current CDNS budget:
• Purchase of new building codes, approximately $5000. The necessary copies of the seven core 2018 I-
Codes will be purchased for staff.
• Staff training on the new codes is mostly accomplished in-house. When possible, staff will attend code
classes that are offered at various times throughout the year. This additional training cost is expected not
to exceed $5,000.00.
Triple Bottom Line Scan
The 2018 I-Codes adoption was not identified as one of the select major projects requiring a triple bottom line
scan.
BOARD / COMMISSION RECOMMENDATION

City Code Update
Russ Hovland, Chief Building Official
(attachments available upon request)
Mr. Hovland presented the 2018 International Building Codes and International Residential Codes (IBC
and IRC, respectively) to the Energy Board in January; at the time staff was seeking support to bypass the
2018 IBC, which the board was supportive of. Mr. Hovland said staff has since identified a few issues
with bypassing 2018 updates: The 2015 Energy Policy commits to adopting codes within 12 months of
issuance; furthermore, if the City falls more than 12 months behind the code issuance, the Insurance
Services Office will downgrade the City’s rating which can affect homeowner’s insurance rates within the
City. Additionally, neighboring communities such has Longmont and Loveland are planning to move
ahead with the 2018 codes in January, and Fort Collins City staff do not want to fall too far behind.
The Code Review Committee met several times over the last few months and proposed a few
amendments to both the 2018 IBC and IRC. Mr. Hovland described the following amendments for the
board and added that staff’s cost assumptions (included in attachments) were determined after reaching
out to the tradespeople who would be involved with the code requirement such as electricians, plumbers,
mechanical contractors, and fire-suppression contractors. Construction supply houses were contacted for
an estimate of off-the-shelf materials.
The proposed amendments to the 2018 IBC include: In new commercial and multi-family buildings when
a trash chute is provided as typical in a multi-story apartment building, a second chute for recycling must
be provided. In new multi-family buildings 10% of all parking spaces must provide a conduit from the
electrical room to the front of the parking space for the purpose installing electric vehicle charging
equipment in the future. A new no-fee emergency repair permit provision was added to allow a permit to
be issued quickly in a disaster/damage situation where a building owner can temporarily repair a building
(house) to allow occupancy while more permanent repairs are forthcoming. This was recommended by
the county building department who scrambled to put this in place after several recent disasters.
The proposed amendments to the 2018 IRC include: New homes are to be provided with an empty ¾”
conduit from the attic to the main electrical panel for ease of installing future photovoltaic (PV) system
signaling wiring. New homes are to be provided with an empty ¾” conduit from the main electrical panel
board to an empty junction box in the garage for ease of installing future electrical vehicle (EV) charging
outlet. Window u-value (the rate of heath loss) will go change from .32 to .30 an increase in efficiency
and approximate cost increase of 8% for vinyl windows.

October 11, 2018
Excerpt from minutes
Energy Board Minutes
DRAFT October 11, 2018
Board members discussed the lack of Electric Vehicle Readiness in new commercial buildings, as
outlined for the multi-family amendment. Mr. Hovland said there was an issue around who would be
using those spaces (depending on the use of the building), like building employees versus customers, and
because of that the review committee elected to only amend the code for multi-family buildings. Board
members expressed their disappointment and said that much like solar-ready rooftops, the code does not
require the installation of the panels, only the infrastructure, and they believe the same methodology
should be put place for EV readiness. Mr. Hovland said if the Board is recommends including commercial
EV Readiness in the amendments, he would bring that feedback to the code review committee prior to
taking this item to City Council.
Board member Fassler said the building code is week, and for an organization with lofty Climate Action
Plan goals we should be striving to exceed the current standards; he disagrees with the review
committee’s amendment to allow existing construction to use a less efficient window u-value. Mr.
Hovland said the builders were concerned with home renovations, but board members felt that the
builders are not being ambitious enough because the cost will be passed onto the consumer regardless.
Board member Fassler moved to recommend the adoption of the 2018 International Codes and
References, with any necessary local amendments, except the allowance of a .32 window u-value for
existing homes.
Chairperson Michell proposed a friendly amendment, to recommend the adoption of the 2018
International Codes and References, with any necessary local amendments, except the allowance
of a .32 window u-value for existing homes, and include an amendment requiring commercial
new-construction to install EV readiness infrastructure.
Board member Becker would like to include an additional friendly amendment, the Energy
Board regrets the 2018 International Codes and References are insufficiently ambitious to
meet the City’s Climate Action Plan goals. The Board recommends the adoption of the
codes with any necessary local amendments; however, they also recommend striking the
allowance of a .32 window u-value for existing homes and would like the amendments to
include a provision requiring commercial new-construction to install EV readiness
infrastructure.
The proposed friendly amendments were accepted by the Energy Board.
Board member Becker seconded the motion.
Discussion:
Vice Chairperson Shores asked what the harm would be to vote no, since the Board has so many
stipulations. Chairperson Michell said a no-vote could be misconstrued as a vote to not update the codes
at all, which is not what the Board wants either. Mr. Hovland said a very similar situation happened when
they presented the codes to the Water Board, and they ultimately voted to approve the 2018 codes on the
condition that staff went back to the review committee to discuss the Board’s amendments. Mr. Hovland
said he would do the same for the Energy Board.
Vote on the Motion: It passed, 7-2
Vice Chairperson Shores said the codes are not ambitious enough. Board member Becker agreed, a yes
vote with all the conditional reasoning is not enough. He added that he voted no after Mr. Hovland’s last
presentation in January.

code. The City established a working group to review the 2018 IBC and will
now be on a process to update the code every three years.
b. Questions asked by the LLAC included: whether the electric vehicle ready
requirement will be for garages or surface lots, Whether the requirement will
change the width of spaces, How the EV ready framework will transform to
EV service, Whether or not the residential code acknowledge battery storage
for the future, What impact of multifamily EV spaces will have on affordability,
What does the window efficiency requirement buy you, If there isn't a change
in efficiency, why wouldn't we wait for a better product that can really change
the impact, Daycare facilities impact with local changes, When considering
code impacts, do we look at the large picture, Update on the process and
timeliness of permits, Do you bring in other boards to see impact and is there
any consideration of regionalizing codes and expectations?
III. Housekeeping
a. Action to take: The committee noted that process improvements in
development review are still uncertain, but on the right path. It was also
noted that the inspection team at the City was much stronger today than in
the past.

DISCUSSION ITEMS
1. Building Code Update
Bob Poncelow introduced Russ Hovland, City of Fort Collins Chief Building Official, who
was present to discuss the ordinances and local amendments relating to the 2018
adoption of the building codes.
Russ Hovland explained that he is providing public outreach with a presentation on the
2018 codes to numerous boards and commissions and will also be presenting it to City
Council. Gerry Horak stated he would like to see the years of service added to the list
of 2018 Building Code Adoption Review Committee members. Gerry advised he would
also like to see those codes being eliminated be tracked somehow.
Bob Poncelow advised the recommendation of the adoption of the International Fire

B. 2018 International Building Code Updates—Russ Hovland, Chief Building Official
Going to council December 4 to propose adoption of updates to codes. Started review
committee in June and met for three months. Builders, architects, developers, City staff,
firefighters, etc. Suggested changes to code and then conducted outreach—take concerns
back to committee to address.
Comments/Q&A:
• Curt: Can you give a quick overview of changes?
o Russ: Changes between 2015-2018 code as written were very minimal. The
fewest I’ve seen in 15 years. We can delete the local amendments because they
are now included right in the code—able to delete about a third of the 200 pages
of local amendments.
• Jeff: There was a perfect match between local and international code?
o Russ: Yes. One example is radon: there were a couple things in our amendment
that weren’t in the code body.
o Jeff: How did you get it so right?
o Russ: We had a lot of really intelligent people, especially in the Utilities
Department, who all got together about what they foresaw for the future. A lot
was energy code based, radon, air quality. Brought this to us and we made
those local amendments.
• Rachel: What if the code changes in the middle of a project?
o Russ: You are vested at the time you apply for your permit.
• Sue: Are there new local amendments?

10/11/2018 – MINUTES Page 2
o Russ: Yes, a couple new ones. For multifamily—the trash chute must have a
paired recycling chute. Unless these are side-by-side, recyclables tend to get
landfilled. That’s an approximate cost increase of $1,500 per floor. Another
amendment is in multifamily: 10% of parking spaces must provide an empty
electrical conduit for installing EV charging equipment in the future. About $300
per parking space.
o Sue: Could this be waved if there’s an affordable housing developer? For
example, Oakridge got their parking space reduced after some studies on
seniors who have vehicles. What if there’s a community that says we don’t
foresee our population using it?
o Russ: Council would have to approve that. It’s problematic when we wave
something for someone and then others want that as well. The one thing on this
requirement is that the goal is to eventually reduce costs. In the next 10 years,
we imagine EV prices going way down and these projects will already have the
infrastructure in place.
o Jen: It’s more expensive to retrofit after construction?
o Russ: Yes, retrofitting is very expensive. We landed on 10% of parking spaces
based on research: Aspen is doing 3%, Atlanta 20%, Boulder 10%.
• Russ: There’s a new emergency no-fee permit. For example, after a flood, very quick
free permits are needed. Adding that to the administrative part of the code.
• Russ: For single family homes, change in requirement of window efficiency. Changing
from .32 to .30 U value, slight increase in energy efficiency. Increase in cost per window
by about 8%. $200-$300 total for whole house window replacement.
o Jen: Is there much production of windows that don’t meet these values?
o Russ: Yes, but there are tons of windows that do meet this requirement and
better. They’re readily available.
• Sue: In your outreach, have people voiced concerns?
o Russ: Yeah, a couple. Chamber of Commerce had a concern about people
choosing to have an in-home daycare. By code and state law, allowed to have 5
kids, and when you have up to 5, that home does not change occupancy.
Doesn’t change to commercial daycare, not a lot of regulations. State regulated
and not locally regulated. Threw a requirement in the code that they have to fire
sprinkler the house, and this will start to impact a lot of people. Went into that
code section and struck out sprinkler requirement completely—is there any loss
of safety here? Not really. Reviewed this with the fire department and decided it
didn’t decrease safety for these homes to be without fire sprinklers.
o Russ: The Water Board wanted lower flow on shower heads and a fix to the toilet
requirement. The toilet flushing performance is called a map score –the higher,
the better. If you raise the map score, fewer flushes leads to lower water
consumption. Increased from 300 to 600 map score requirement.

REGULAR MEETING
10/11/2018 – MINUTES Page 3
o Russ: We were considering removing the U value requirement for windows, and
the Energy Board wanted to keep it.
Catherine: What happens if you don’t have vinyl windows? Like in my old
house from the 1800s.
Curt: This would be for new construction.
Catherine: What if I add an addition to an older house?
Russ: If someone is doing an addition in Old Town and they want to
match the windows, they may not be able to get the U value, and they can
come to the City for a variance.
• Sue: Would you welcome a recommendation from this board, or what would be helpful?
o Russ: Just a general agreement/vote that you support me taking these to
Council for adoption in December.
• Jen: Were any codes removed?
o Russ: Yes, there are occasionally codes removed. When you replace a water
heater, we used to require a combustion safety test to make sure it’s safe. The
problem is now that the homeowner wants to do their own water heater
replacement and has to pay to get the tests done, what we found is that people
stopped getting permits for water heaters. We analyzed whether or not the code
was serving its purpose, and decided no. We still do an inspection, we just no
longer require a combustion safety test.
• Curt: Doing the math on adding EV spaces to housing developments, it doesn’t seem
like enough to cause a big issue.
o Russ: And I think we can get those costs down, that’s the high-end, worst-case
scenario price at $300/space.
o Curt: For individual homeowners, there was already a requirement for the
conduit.
o Russ: Yes, just the size of the conduit increased.
Jen moved to support the internal building code update amendments.
Rachel seconded. Motion passed unanimously 5-0-0.

2. UPDATES TO 2015 BUILDING ORDINANCE
Russ Hovland, Department Head Building Services met with the NRAB to secure support for the
2018 updates to the Building Code. He explained that updates to the code occur every 3 years.
The particular updates to highlight for this evening’s discussion concern waste recycling, electric
vehicles, and emergency repair permits in disaster. These changes, he points out, are minimal.
Specifically, the change regarding recyclable materials requires multi-story, multi-family buildings to
have an additional disposal option for recyclable materials in addition to regular waste receptacles.
He points out that many builders already do this, thus, the impact is minimal.
Also proposed for the buildings are 10% EV Ready conduits for future Electric Vehicle charging
stations. Similar ordinances already exist for single family homes. There is an upgrade as well from
½” to ¾” conduits because electric vehicles require the upgrade.
Speaking for the NRAB, Luke Caldwell told Russ that the members feel the ordinance changes are
appropriate and want to record their support therefore.

3. 2018 I-CODES ADOPTION
Staff Report
Mr. Hovland presented the staff report and discussed each International Code being adopted. He noted
the 2015 Codes were adopted late, in 2017, and the goal is to implement a regular adoption schedule
every three years and to adopt the new Codes within 12 months of issuance.

ATTACHMENT 10
DRAFT EXCERPT
City of Fort Collins Page 2 October 25, 2018
Advantages of this schedule will be to minimize the impacts of changes and lessen the degree of
construction cost increases as well as lessen ISO insurance rates.
Mr. Hovland discussed the process involved in examining the Codes for adoption, which began with
the formation of a committee of staff and stakeholders to review the Codes and local amendments. He
noted many of the local amendments are now in the Code which allowed about 1/3 of local amendments
to be deleted.
Mr. Hovland highlighted some proposed local amendments to the Codes. For the International Building
Code IBC, an amendment is planned to require a recycling chute next to any provided trash chute in
multi-story, multi-family buildings.
Additionally, for multi-family buildings, 10% of parking spaces must have a conduit from the electrical
room to the front of the parking space for the purpose of installing electric vehicle charging equipment
in the future. Mr. Johnson expressed concern about the requirement causing a spider web effect in a
small space. Mr. Hovland replied the Committee left flexibility on how the goal is achieved.
Mr. Hovland stated an emergency no-fee repair permit for disasters will be added to the IBC as well.
Mr. Hovland discussed minimal changes to the International Residential Code.
Mr. Hovland went on to discuss changes resulting from yesterday's final Committee meeting, one of
which involved sprinkler requirements for in-home daycares of 5 or less children. The City does not
receive notification of daycares as they are state regulated facilities; therefore, staff worked with Fire
Chief Poncelow to remove the requirement as the home is not changing occupancy and there are 5 or
less children. Mr. Reider expressed support for the change and Mr. Hovland noted there are other
state fire requirements for such daycares.
Mr. Hovland stated City Council has asked about roof shingle waste over the last few years given the
number of hail storms. Staff found construction materials, including shingles, make up 50% of landfill
materials and there is no place for shingle recycling in Northern Colorado. The Committee discussed
impact-resistant shingles at its meeting yesterday and ultimately voted to bring a local amendment to
require class four impact-resistant shingles for all asphalt roofs. Mr. Hovland noted the class four
shingles would likely still be destroyed in very severe hail storms with larger than golf ball size hail.
Mr. Reider expressed support for this amendment and asked if a re-roof would also require the class
four shingles. Mr. Hovland replied in the affirmative.
Mr. Reider mentioned homeowner's insurance policies can include riders for Code updates which would
enable homeowners to get replacement class four shingles. He suggested staff notify area insurance
agents.
Mr. Massey asked for more detail about class four shingles. Mr. Hovland described the testing process
and stated there are two types of class four shingles, one with a rubber backing and one with a
fiberglass backing. The rubberized-backed shingles have been found to be much more storm resistant.
Mr. Massey asked if it is assumed an older roof structure could handle the weight of class four shingles.
Mr. Hovland replied the Committee did not examine the potential weight of the shingles but stated older
buildings with 2x4 rafters may need to be examined. He noted there is currently no requirement for a
structural analysis unless the roof is concrete tile.
Ms. Penning expressed concern with imposing the requirement on older homes. Mr. Hovland replied
he would be more concerned with the weight issue if roofs were getting an overlay. He noted the
current Code only allows two layers and suggested language could be added to the amendment to
require structural evaluation if an overlay is planned.
Mr. Hovland stated the next local amendment is to change the showerhead flow rate from 2.0 gallons
per minute to 1.8 to lower water consumption. The estimate for water savings at total City build-out is
1.8 million gallons per year. Mr. Reider asked if the Committee considered longer shower use if the
flow is decreased. Mr. Hovland replied the Committee ultimately felt the savings was still worth the
change and stated the amendment can be reversed in three years if it is found to be an issue.
Mr. Hovland noted water conservation staff wanted to require low-flow toilets as well; however, the cast
iron and clay sewer systems do not allow waste to get to the main sewer line with these low-flow toilets.
Instead, staff opted to require increased MaP scores, which provide an indication of flush performance.
DRAFT EXCERPT
City of Fort Collins Page 3 October 25, 2018
Mr. Reider asked if the City has any plans to research the regulation of flushable wipes. Mr. Hovland
replied that issue will be examined over the next three years prior to the next Code cycle.
Mr. Hovland stated the last local amendment was a request from the Commission on Disability involving
an increase to the 30" width required for roll-in showers in multi-family buildings. The Commission
requested an increase from 30" x 60" to 36" x 60" minimum.
Mr. Marzonie asked about the number of accessible units required in multi-family buildings. Mr.
Hovland replied buildings of 26 units must provide one roll-in shower, 55 or 56 units must provide a
second, etc. The number of showers required will not change as part of this amendment.
Mr. Hovland reviewed the timeline for adoption of the Code changes.
Public Input
No members of the public were present.
Board Questions and Discussion
There was no further discussion.
Board Deliberation
Mr. Massey moved that the Building Review Board recommend the City adopt the 2018
International Codes with the local amendments as discussed.
Mr. Reider seconded. Motion passed 5:0.
