If so,the roof structure code compliance check consists of the Contractor's visual roof audit,checking for unusual sagging or deterioration, without requiring additional measurements of existing rafters to check against span tables. — For CBOs of jurisdictions with evidence of structurally deficient one-and two-family housing stock or poor structural code compliance history, the CBO may elect to add the rafter span check option described in the criteria. The Structural Toolkit and CRC Wind Speeds The 2013 CRC contains an inconsistency related to wind speeds. Despite referencing ASCE 7-10 as its standard,the 2013 CRC's text and tables use outdated ASCE 7-05 wind speeds. Under the old ASCE 7-05 /CBC 2010,the basic design wind speed in most regions of the state was 85 mph(max.3 second gust in 50 years).Under ASCE 7-10/CBC 2013,the design wind speed has increased to 110 mph(max.3 second gust in 700 years).Despite the different definitions of wind speed,design wind pressures remain essentially unchanged. Because the Toolkit's structural document is intended to be forward looking,all wind speeds in the Toolkit document are based on the ASCE 7-10.This is clearly stated in the caption to the state wind speed map,and in the Table 1 footnotes.This anticipates an obvious and expected correction to the CRC;otherwise the Toolkit would become immediately outdated when the CRC is amended to change the base design wind speed from 85 mph to 110 mph. 2013 CRC text(ASCE 7-05)wind speeds equivalent to the 2013 CRC and CBC Reference Standard(ASCE 7- 10)are shown below.See ASCE 7-10 Table C26.5-6 for additional information. 2013 CRC text 2013 CRC and CBC Referenced Standard ASCE 7-05 ASCE 7-10 85 mph 110 mph 90 mph 115 mph 95 mph 120 mph 100 mph 126 mph 105 mph 133 mph (Introductory text provided for jurisdiction's reference only. Do not attach to Criteria that follow.) Structural Technical Appendix This toolkit document is supported by a Structural Teclunical Appendix that describes the technical analysis behind these criteria,which are based on structural engineering principles and the California Building and Residential Codes.The Technical Appendix also provides some additional guidance to address non- conforming items,such as when an anchor layout is not based on a solar support component manufacturer's guidelines,or when a coastal site is located within 200 yards of the ocean(Exposure D).This document can be found online. Probability of Code Compliance The Structural Technical Appendix includes a section that examines the probabilities associated with the assumptions behind Table 1 that allows six feet cross-slope anchor spacing in some circumstances. That statistical analysis estimates that the probability of code noncompliance for six feet anchor spacing is only 2 in a thousand installations(0.2%).Note that probability of structural failure is orders of magnitude lower than the probability of code noncompliance.

Req'd Calc. Req'd Calc. Req'd Solar support component manufacturer's guidelines may be relied upon to ensure the array above the roof is properly designed,but manufacturer's guidelines typically do NOT check to ensure that the roof itself can support the concentrated loads from the solar array. Table 1 assumes that the roof complied with the building code in effect at the time of construction,and places limits on anchor horizontal spacing to ensure that a roof structure is not overloaded under either downward loads or wind uplift loads.Note 4 below lists the basic assumptions upon which this table is based. Table 1 Notes: 1. Anchors are also known as"stand-offs';"feet "mounts"or"points of attachment". Horizontal anchor spacing is also known as `cross-slope"or"east-west"anchor spacing(see Figure 2). 2. If anchors are staggered from row-to-row going up the roof; the anchor spacing may be twice that shown above,but no greater than 6'-0': 3. For manufactured plated wood trusses at slopes of flat to 6:12,the horizontal anchor spacing shall not exceed 4'-0"and anchors in adjacent rows shall be staggered. 4. This table is based on the following assumptions: • The roof structure conformed to building code requirements at the time it was built. • The attached list of criteria are met. • Mean roof height is not greater than 40 feet. • Roof sheathing is at least 7/16"thick oriented strand board or plywood. lx skip sheathing is acceptable. • If the dwelling is in Wind Exposure B(typical urban,suburban or wooded areas farther than 500 yards from large open fields),no more than one of the following conditions apply: — The dwelling is located in a special wind region with design wind speed between 115 and 130 mph per ASCE 7-10,or — The dwelling is located on the top half of a tall hill,provided average slope steeper is less than 15%. • If the dwelling is hi Wind Exposure C(within 500 yards of large open fields or grasslands),all of the following conditions apply: — Design wind speed is 110 mph or less(not in a Special Wind Region),and — The dwelling is not located on the top half of a tall hill. • The solar array displaces roof live loads(temporary construction loads)that the roof was originally designed to carry. • The Structural Technical Appendix provides additional information about analysis asstunptions.

Table 2 is an optional table some CBOs may elect to use to provide additional assurance by requiring a check of existing roof rafter spans,and supports optional criteria 1.8.5 and 1.8.6.For post-1960 construction,these span tables match the rafter span tables found in the 2013 California Building and Residential codes.For pre-1960 construction,the rafter span tables are based on structural calculations with lumber sizes and wood species&grade appropriate for older construction.Note 5 below lists the basic assumptions upon which this table is based. Table 2 Notes: 1. See Figure 4 for definition of roof rafter maximum horizontal span. 2. "Non-tile Roof"=asphalt shingle,wood shingle&wood shake,with an assumed roof assembly weight of 10 psf. 3. "Tile Roof"=clay tile or cement tile,with an assumed roof assembly weight of 20psf 4. Unaltered manufactured plated-wood trusses may be assumed to be code compliant and meet intent of Table 2. 5. This table is based on the following assumptions: • Span/deflection ratio is equal to or greater than 180. • For post-1960 construction,wood species and grade is Douglas Fir-Larch No.2. • For pre-1960 construction,wood species and grade is Douglas Fir-Larch No. 1. • Other wood species and/or grade are also acceptable if allowable bending stress is equal or greater to that listed above.
