<br />2304.12 Protection against decay and termites. Wood shall be protected from decay and termites in
<br />accordance with the applicable provisions of Sections 2304.12.1 through 2304.12.4.
<br />2304.12.1 Locations requiring waterborne preservatives or naturally durable wood. Wood used
<br />above ground in the locations specified in Sections 2304.12.1.1 through 2304.12.1.5 shall be naturally
<br />durable wood or preservative-treated wood using waterborne preservatives, in accordance with AWPA
<br />U1 for above-ground use.
<br />2304.12.1.1 Joists, girders and subfloor. Wood joists or wood structural floors that are closer
<br />than 18 inches (457 mm) or wood girders that are closer than 12 inches (305 mm) to the
<br />exposed ground in crawl spaces or unexcavated area located within the perimeter of the building
<br />foundation shall be of naturally durable or preservative-treated wood.
<br />2304.12.1.1.1 [SPCB] There shall be a clearance of at least 18 inches (457 mm) between
<br />the underside of wood floor joists and the finished surface of the ground, and at least 12
<br />inches (305 mm) between the underside of any other wood horizontal framing member
<br />and the finished surface of the ground. The ground underneath floor joists shall be leveled
<br />or smoothed off so as to maintain a reasonably even surface.
<br />Exception: For purposes of structural pest control inspection, a minimum of 12 inches
<br />(305 mm) of clearance under-floor joists shall be considered adequate except that such
<br />clearance shall not be necessary where the subarea soil is of such a nature as to prevent
<br />excavation or where excavation would create a hazard from shifting soil or other causes.
<br />2304.12.1.2 Wood supported by exterior foundation walls. Wood framing members, including
<br />wood sheathing, that are in contact with exterior foundation walls and are less than 8 inches (203
<br />mm) from exposed earth shall be of naturally durable or preservative-treated wood.
<br />Exception: [DSA-SS and OSHPD 1, 1R, 2, 4 & 5] At exterior walls where the earth is paved
<br />with an asphalt or concrete slab at least 18 inches (457 mm) wide and draining away from the
<br />building, the bottom of sills are permitted to be 6 inches (152 mm) above the top of such slab.
<br />Other equivalent means of termite and decay protection may be accepted by the enforcement
<br />agency.
<br />2304.12.1.3 Exterior walls below grade. Wood framing members and furring strips in direct
<br />contact with the interior of exterior masonry or concrete walls below grade shall be of naturally
<br />durable or preservative-treated wood.
<br />2304.12.1.4 Sleepers and sills. Sleepers and sills on a concrete or masonry slab that is in direct
<br />contact with earth shall be of naturally durable or preservative-treated wood.
<br />2304.12.1.5 Wood siding. Clearance between wood siding and earth on the exterior of a
<br />building shall be not less than 6 inches (152 mm) or less than 2 inches (51 mm) vertical from
<br />concrete steps, porch slabs, patio slabs and similar horizontal surfaces exposed to the weather
<br />except where siding, sheathing and wall framing are of naturally durable or preservative-treated
<br />wood.
<br />2304.12.2 Other locations. Wood used in the locations specified in Sections 2304.12.2.1 through
<br />2304.12.2.8 shall be naturally durable wood or preservative-treated wood in accordance with AWPA
<br />U1. Preservative-treated wood used in interior locations shall be protected with two coats of urethane,
<br />shellac, latex epoxy or varnish unless waterborne preservatives are used. Prior to application of the
<br />protective finish, the wood shall be dried in accordance with the manufacturer's recommendations.
<br />2304.12.2.1 Girder ends. The ends of wood girders entering masonry or concrete walls shall be
<br />provided with a 1/2-inch (12.7 mm) airspace on top, sides and end, unless naturally durable or
<br />preservative-treated wood is used.
<br />2304.12.2.2 Posts or columns. Posts or columns supporting permanent structures and
<br />supported by a concrete or masonry slab or footing that is in direct contact with the earth shall be
<br />of naturally durable or preservative-treated wood.
<br />Exception: Posts or columns that meet all of the following:
<br />1. Are not exposed to the weather, or are protected by a roof, eave, overhang, or other
<br />covering if exposed to the weather.
<br />2. Are supported by concrete piers or metal pedestals projected not less than 1 inch (25
<br />mm) above the slab or deck and are separated from the concrete pier by an impervious
<br />moisture barrier.
<br />3. Are located not less than 8 inches (203 mm) above exposed earth.
<br />2304.12.2.3 Supporting member for permanent appurtenances. Naturally durable or
<br />preservative-treated wood shall be utilized for those portions of wood members that form the
<br />structural supports of buildings, balconies, porches or similar permanent building appurtenances
<br />where such members are exposed to the weather without adequate protection from a roof, eave,
<br />overhang or other covering to prevent moisture or water accumulation on the surface or at joints
<br />between members.
<br />Exception: Sawn lumber in buildings located in a geographical region where experience has
<br />demonstrated that climatic conditions preclude the need to use durable materials where the
<br />structure is exposed to the weather.
<br />2304.12.2.4 Supporting members for permeable floors and roofs. Wood structural members
<br />that support moisture-permeable floors or roofs that are exposed to the weather, such as
<br />concrete or masonry slabs, shall be of naturally durable or preservative-treated wood unless
<br />separated from such floors or roofs by an impervious moisture barrier. The impervious moisture
<br />barrier system protecting the structure supporting floors shall provide positive drainage of water
<br />that infiltrates the moisture-permeable floor topping.
<br />2304.12.2.5 Ventilation beneath balcony or elevated walking surfaces. Enclosed framing in
<br />exterior balconies and elevated walking surfaces that have weatherexposed surfaces shall be
<br />provided with openings that provide a net free cross-ventilation area not less than 1

<br />exposed earth shall be naturally durable for both decay and termite resistance or preservative
<br />treated in accordance with AWPA U1 for soil or fresh use.
<br />Exception: Untreated wood is permitted where such wood is continuously and entirely below the
<br />ground-water level or submerged in fresh water.
<br />2304.12.2.6.1 Posts or columns. Posts and columns that are supporting permanent
<br />structures and embedded in concrete that is exposed to the weather or in direct contact
<br />with the earth shall be of preservative-treated wood.
<br />2304.12.2.7 Termite protection. In geographical areas where hazard of termite damage is
<br />known to be very heavy, wood floor framing in the locations specified in Section 2304.12.1.1 and
<br />exposed framing of exterior decks or balconies shall be of naturally durable species (termite
<br />resistant) or preservative treated in accordance with AWPA U1 for the species, product
<br />preservative and end use or provided with approved methods of termite protection.
<br />2304.12.2.8 Wood used in retaining walls and cribs. Wood installed in retaining or crib walls
<br />shall be preservative treated in accordance with AWPA U1 for soil and fresh water use.
<br />2304.12.3 Attic ventilation. For attic ventilation, see Section 1202.2.2.
<br />2304.12.4 Under-floor ventilation (crawl space). For under-floor ventilation (crawl space), see
<br />Section 1202.4.
<br />2304.12.8 Separate wood framing. [SPCB] Correct the conditions in frame and stucco walls and
<br />similar appurtenant construction so that the wood framing is separate from the main structure by a
<br />complete concrete or masonry plug with no voids that will allow infestations to enter the structure from
<br />the wall. If there is no plug, the foundation shall be 2 inches (51 mm) or more above the grade levels
<br />and at least as high as the adjoining slabs or 4-inch (102 mm) concrete barrier seat off installed.
<br />2304.12.9 Earth fills. [SPCB] Separate the earth fills such as under porches or paving from all
<br />woodwork by concrete, masonry, good quality cement plaster or other material approved by local
<br />building codes. Chemical treatment of earth fills is considered adequate if the foundation adjoining the
<br />fill meets standards of the current building codes.
