Treated wood for garage door frame

[bnymbill]

I see this frequently and it takes a long time to rot but it's inevitable. It might fit category 5 of Protection of Wood and Wood-Based Products Against Decay (R317 in 2015 IRC; R304 in 2024 IRC).

Number 5 reads, "Wood siding, sheathing and framing members on the exterior of a building having a clearance of less than 6" from the ground or less than 2" measured vertically from concrete steps, porch slabs, patio slabs and similar horizontal surfaces exposed to the weather."

Curious if anyone is calling this out during an inspection and what code reference is used?

Typically see the stem wall extend up and a treated jamb liner run down the inner side to the concrete. Even the treated will eventually decay. A small gap at the bottom can help a lot. 317.1 #2, #5 and 404.1.6 as needed.

I agree, a small gap would do wonders or even wrap the bottom with AAMA 711 flashing.
