BUILDING PLANNING The property line concept is a convenient means of ,protecting one building from_another as far as expo- sure is concerned. Exposure is the potential for heat to be transmitted from one building to another during a fire in the exposing building. Radiation is the primary means of heat transfer. 4 Wallsless than 5 feet (1525 mm) from the property line must be of 1 -hour fire-resistant construction. The tire -resistance rating also requires the rating expo- sure to be for both sides. The exterior rated walls should be tested in accordance with either ASTM E 119 or UL 263. This is not intended to limit fire -resis- tance -rated assemblies solely to the test criteria con- tained in these standards. Section R104.11 still allows the building official to approve alternative fire -resis- tance methodologies, such as those described in Sec- tion 703.3 of the IBC. This would still allow a builder to use acceptable engineering analysis, calculations in accordance with Section 721 of the IBC or prescrip- tive assemblies permitted by Section 720 of the IBC as alternatives to the standards contained within the code. Projections must not extend more than 12 inches (305 mm) into the area where openings are prohib- ited. Therefore, projections cannot be closer than 2 feetj610 mm) from the lot line. Projections that are less than 5 feet (1525 mm) from the lot line are re- quired to be protected on the underside with 1 -hour fire-resistant construction [see Commentary Figure R302.1(1)]. Unlike the IBC, the code does not set a distance from the property line at which openings must be pro- tected. Openings are notpermitted in exterior waplg where the exterior wall has a fire separation distand: of less than 3 fe (914 mm) fro_m_Ite Open/ ings in a wall located at a distance equal to or greater than 3 feet (914 mm), but less than 5 feet (1525 mm) from the lot line cannot exceed 25 percent of the maxi- mum_ wall area_ [see Commentary Figures R302.1(2) and! R302.1(3)]. Openings,jDrojections or penetra- tions that are 90 degrees (1.57 rad) (perpendicular) to the line used to determine the fire separation distance are not prohibited. Section R302.4 describes through penetrations and membrane penetrations in detail. See the definition of "Fire separation distance" in Chapter 2. The requirements for protection do not ap- ply to walls that are at a right angle (perpendicular to) the property line [see Commentary Figures R302.1(2) and R302.1(3)]. Exception 1 applies to detached tool and storage sheds, playhouses and similar structures that are exempt from permits. Projections from these structures, however, are not permitted to extend over the property line. Exception 2 will allow roof eave projection for de- tached garages to be closer than 2 feet (610 mm) from the lot line, but limits the roof eave projection to 4 inches (102 mm). This projection cannot extend over the property line. Exception 3 allows foundation vents installed in compliance with the code in areas where openings are otherwise prohibited. 1 -HOUR FIRE -RESISTANCE RATING c 5 WITH EXPOSURE FROM BOTH SIDES FT I PROJECTION f+— 2FT —► LINE USED TO DETERMINE -- /111 THE FIRE SEPARATION DISTANCE ,-PROJECTION RESISTANCE OF WALL 1 -HOUR FIRE AND PROJECTION NOT REQUIRED EXTERIOR WALL For SI: 1 foot = 304.8 mm. 1 -HOUR FIRE -RESISTANCE -RATED CONSTRUCTION ON UNDERSIDE OF PROJECTION EXTERIOR WALL 1 -HOUR FIRE-RES/STANCE-RATED I a 2 FT < 5 FT CONSTRUCTION ON L— —.
