The purpose of this item is to recommend adoption the 2012 International Codes (I-Codes). The 2012 I- Codes represent the most up-to-date construction standards establishing minimum requirements to safeguard the public health, safety, and general welfare from hazards attributed to the built environment within the City of Fort Collins. STAFF RECOMMENDATION Staff recommends adoption of the 2012 I-Codes and the associated local amendments. Key recommendations include: 1. Proposing to amend the International Building Code (IBC) to require that new Group R-2 (multi-family buildings) be provided with the enhanced fire-suppressions (fire-sprinkler) system, NFPA 13, which would provide sprinkler head protection in attic spaces not currently required to be protected. This amendment is proposed to become effective July 1, 2014, providing sufficient time for designers and developers to make the appropriate changes to construction documents. Please see local amendment to the IBC Section 903.3.1.2. 2. Proposing to amend the IBC and International Residential Code (IRC) by disallowing the use of vinyl and polypropylene siding materials on new buildings. Vinyl siding products have been found to be ATTACHMENT 1 Agenda Item 17 Item # 17 Page 2 contributors of flame spread in recent local fires causing extensive damage and property loss. Vinyl siding products tend to warp and crack over time when exposed to sunlight, especially at higher altitudes. Vinyl siding products are mostly used on low income multi-family housing projects and have not been used on single-family products for at least the past decade. Please see local amendments to the IBC Sections 1404.9 and 1404.12 and local amendments to the IRC Sections R703.11 and R703.11.3. 3. Proposing to amend the IBC and IRC to improve the Construction Waste Management Plan (CWMP), currently required for new buildings only, to require recycling of construction waste such as wood, concrete and masonry, metals, and cardboard during remodels and additions over 2500 square feet. Also, proposing that supporting documentation that verifies compliance with the CWMP would be required before the Certificate of Occupancy can be issued. Please see local amendment to the IBC Section 3602.1 and local amendment to the IRC Section R324.1. 4. Proposing to amend the IBC and IRC to require a demolition/recycling plan for all buildings being demolished. The amendment would require the removal of all hazards such as asbestos and lead paint, removal and recycling of all reusable components such as cabinets, doors, windows, and fixtures. All remaining wood, concrete and masonry, metals, and cardboard is to be recycled in accordance with a Construction Waste Management Plan. Please see local amendment to the IBC Section 3602.1.1 and local amendment to the IRC Section R324.1.1. 5. Proposing to amend the IRC to require fire-sprinkler systems in new duplex and new townhome projects. This proposal is to become effective July 1, 2014. Please see local amendment to the IRC Sections R313.1 and R313.2. 6. Proposing to amend the International Energy Conservation Code (IECC) to require an air-tightness test in multi-family buildings that verifies that the air leakage between dwelling units, across the common wall, meets Leadership in Energy and Environmental Design (LEED) for Homes Multi-Family criteria of not more than .30 CFM/cubic feet/of surface area. This criteria is equivalent to the air tightness requirements currently in place for detached single-family homes. Recognizing that designers will need time to incorporate construction details to meet this amendment, staff suggests that this proposal become effective July 1, 2014. Please see local amendment to the IECC Section R402.4.1. BACKGROUND / DISCUSSION The International Codes and standards are reviewed and voted on by construction industry professionals from across the country and published every three years under the oversight of the International Code Council (ICC). The latest publications brought forth by the ICC are the proposed 2012 International Codes intended to replace the current City-adopted 2009 International Codes. 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 thirteen (13) times since 1924. Locally, the rational for staff to recommend items #1 and #2 above are the result of recent highly damaging fires at the Buffalo Run and Bull Run apartment complexes. Both complexes were provided with the lower standard NFPA 13R fire-sprinkler system which does not require fire-sprinkler heads in the attic. Both projects were constructed with the required fire barriers in the attic space and these fire-barriers failed to contain the fire spread. Both fires started on the exterior enflaming the vinyl siding products allowing the flames to travel fairly rapidly up the exterior wall surface and into the un-protected wood constructed attic spaces. The construction details incorporated and the siding products used were in compliance with the codes at the time of construction but were proved to be ineffective at retarding a fire which destroyed a dozen apartments before the fire department arrived and extinguished these blazes. These two fire events caused damage estimated at $400,000 and $500,000 respectively, displacing a dozen low income families from their homes Agenda Item 17 Item # 17 Page 3 and destroying all contents and personal belongings. Over the past decade or more, very few multi-family projects were designed with vinyl siding and no single-family detached projects have used vinyl siding products. Staff’s recommendation of item #5 above is based on the understanding that duplex and townhome projects more closely resemble the multi-family projects (which are required to have fire-sprinklers) in that, one occupant or owner has no control over the actions or accidents of a neighbor just a wall thickness away. Requiring fire-sprinkler systems in new single-family detached dwellings is not being recommended with this code adoption cycle. FINANCIAL / ECONOMIC IMPACT The proposed Codes and local amendments will have an economic impact on construction cost of multi-family and attached dwelling units of duplex and townhome projects. Effective July 1, 2014, requiring new multi-family buildings to be protected with the National Fire Protection Association’s NFPA 13 fire-sprinkler system is anticipated to increase the cost of the fire-suppressions system by 35% over the currently allowed NFPA 13R. This calculates to approximately $750 increase per dwelling unit of a multi-family building. Effective July 1, 2014, requiring new duplexes and new townhomes to be provided with a fire-sprinkler system in accordance with the IRC Section P2904 is anticipated to increase construction cost by approximately $1.50 per square foot floor area. IRC’s P2904 fire-sprinkler system is the most cost effective system available with current technology. The system is a combination potable-water/fire-sprinkler system and is installed by a licensed plumber as an extension of the building’s water plumbing system. The P2904 is not anticipated to cause leaks any more often than current water piping systems installed in buildings and is subject to the same freeze protections required of water piping systems in general. Eliminating the use of vinyl siding products on new buildings is anticipated to increase the cost of siding materials by approximately $0.41 per square foot of siding. Labor cost to install siding is the same regardless of the materials used. This calculates to approximately $245.00 increase per dwelling unit, but only on projects that propose the use of vinyl siding. Over the past 12 years or more, very few multi-family projects and no single-family projects have started construction proposing the use vinyl siding products. See Attachment 2 for a breakdown of these cost estimates. ENVIRONMENTAL IMPACTS Improvements being proposed to the Construction Waste Management Plan (CWMP), for new buildings as well as remodeled buildings, will divert additional construction waste from the landfill. Buildings to be demolished will, for the first time in Fort Collins, be required to first remove hazards such as lead paint and asbestos, then remove and recycle any salvageable materials, while complying with the adopted CWMP for all remaining materials such as wood, concrete and masonry, metals, and cardboards. Installing fire-suppression systems in new duplexes and new townhomes is considered by many construction industry organizations as “green building”. Several studies have been completed that tout the environmental benefits of suppressing a building fire with sprinkler systems as opposed to relying on fire departments to extinguish an event. The philosophy of extinguishing a fire through the use of fire-sprinkler systems, versus containing a fire through fire-rated construction has been a key point for the code writers, the International Code Council, since the inception of the I-Codes in 2000. Please see Attachment 3 Residential Sprinkler Reports for the various studies conducted. Multi-family air testing of individual dwelling units, constructed after July 1, 2014, will need to show air tightness similar to new single-family detached homes. It is anticipated that assuring the air tightness of individual dwelling units will significantly improve indoor air quality by reducing air pollutants and odors from transferring between dwelling units across common walls or floor ceiling systems. Agenda Item 17 Item # 17 Page 4 BOARD / COMMISSION RECOMMENDATION Over the past several months, the proposed 2012 I-Codes and local amendments were introduced to numerous City boards and commissions. While there is wide support for the adoption of the 2012 I-Codes including the proposed fire-sprinkler changes to multi-family buildings and requiring fire-sprinklers in attached dwellings such as duplex and townhomes, there is concern over the construction cost increases in general. There is little to no support for requiring fire-sprinklers in new detached single-family homes. See Attachment 4 for the list of presentations and dates, including a brief summary of each along with minutes or actions where provided. PUBLIC OUTREACH In August 2012, a committee was convened for the purpose of reviewing and recommending the adoption of the proposed 2012 I-Codes and accompanying local amendments. The stakeholder’s Code Review Committee represented a wide spectrum of volunteers from across the local construction industry including private developers, builders, architects, engineers, building officials from neighboring jurisdictions and representatives from the Building Review Board and the Poudre Fire Authority. See Attachment 5 for a list of the members of the Code Review Committee. On October 2, 2013 and November 13, 2013, the Code Review Committee met and committee members voted in support of the 2012 I-Codes and accompanying local amendments as proposed, including the six “key recommendations” discussed above. See Attachments 6 and 7 for an abbreviated list of proposed amendments to the IBC and the IRC. Code Review Committee Conclusions: The Committee felt that generally, there are no significant changes in the 2012 IBC that the members considered to be controversial or overly expensive to new construction. The proposed requirements that new multi-family buildings provide fire-sprinklers in the attic and the elimination of vinyl siding products on new buildings were supported and considered important discussion items. The remaining IBC and amendments were supported for adoption. The 2012 IRC requires that all new buildings constructed under the IRC, single-family detached, duplex, and townhomes, be provided with a fire-sprinkler system. A majority of the members voted for support for the fire- sprinkler requirement in new duplexes and new townhomes, and support an effective date of July 1, 2014. The committee members do not support requiring fire-sprinkler systems in new single-family detached projects. The remaining 2012 IRC and amendments were supported for adoption. The proposed codes were introduced to the local Board of Realtors on two separate occasions and the Northern Colorado Home Builders Association. Agenda Item 17 Item # 17 Page 5 ATTACHMENTS 1.
