(detached) and multiple, attached single-family dwellings (townhouses) not more than
three stories in height, with each townhouse having its own separate means of egress.
AF01.3 Purpose. The purpose of this appendix is to provide minimum requirements to
enhance the public safety, health and general welfare, through construction methods
designed and installed to resist entry of radon gas into the occupied spaces of buildings
regulated by this appendix.
SECTION AF102
DEFINITIONS
AF102.1 General. For the purpose of these requirements, the terms used shall be defined
as follows:
DWELLING UNIT, SINGLE-FAMILY DETACHED. An independent building
completely separated from adjacent dwellings by unobstructed physical space,
exclusively containing one dwelling unit located entirely on a separately recorded and
platted parcel of land (site) bounded by property lines, which parcel is deeded exclusively
for such single-family dwelling.
DWELLING UNIT, TWO-FAMILY DETACHED. An independent building
completely separated from adjacent dwellings by unobstructed physical space,
exclusively containing two dwelling units located entirely on a separately recorded and
platted parcel of land (site) bounded by property lines, which parcel is deeded exclusively
for such two-family dwelling.
- 39 -
FOUNDATION DRAIN SYSTEM. A continuous length of drain tile, perforated pipe,
or filter mat extending around all or part of the internal or external perimeter of a
basement or crawl space footing designed to collect and drain away excess subsurface
water. I
RADON. A naturally occurring, chemically inert, radioactive gas that is not detectable
by human senses, that can move readily through particles of soil and rock, and that can
accumulate under the slabs and foundations of homes where it can easily enter the living
space through construction cracks and openings.
SOIL-GAS-RETARDER. A continuous membrane of 3-mil (0.075 mm) cross-linked
polyethylene or other equivalent material used to retard the flow of soil gases into a
building.
SUBFLOOR. A concrete slab or other approved permanent floor system that directly
contacts the ground and is within the walls of the living spaces of the building.
SUB-MEMBRANE DEPRESSURIZATION SYSTEM. A system designed to achieve
lower sub-membrane air pressure relative to crawl space air pressure by use of a vent
drawing air from beneath the soil-gas-retarder membrane.
SUB-SLAB DEPRESSURIZATION SYSTEM (Passive). A system designed to
achieve lower sub-slab air pressure relative to indoor air pressure by use of a vent pipe
routed through the conditioned space of a building and connecting the sub-slab area with
outdoor air, thereby relying on the convective flow of air upward in the vent to draw air
from beneath the slab.
TOWNHOUSE. A single-family dwelling unit constructed as part of a group of two or
more attached individual dwelling units, each of which is separated from the other from
the foundation to the roof and is located entirely on a separately recorded and platted
