Friends:
We just received back from a local jurisdiction a correction notice for a recently submitted permit application. The job is a 12 module roof mount on a tile roof. The jurisdiction is calling for: Show or describe roof framing including rafter type, size, span and spacing. If engineered, manufactured trusses, provide approval for modification of trusses by drilling by a California licensed architect, civil engineer or structural engineer per California Residential Code R802.10.4. The home has prebuilt trusses and was built in the mid-70s. The homeowner does not have blueprints for the home. If I read this correctly, we are being asked to document the roof trusses and to prove it is OK to drill into them. It seems pointless to describe the trusses to a building official as the building official is not qualified to determine if a described truss is adequate. Also, do I really need to have a licensed engineer prove I can set Simpson 1/4X3 SDS lags into a rafter? If ¼ Simpson lag is driven near the center of a truss, there should be no issue. I need: 1. Documentation that would prove the roof loading of less than 3 pounds per square foot with a point load of 59 pounds per connection should not require engineering, and 2. Documentation showing that I can drive ¼ lags into a rafter without an engineers permission. Thanks in advance.
