Building codes exist to ensure safety, and reclaimed lumber is no exception to their reach. In Los Angeles, using salvaged wood in construction requires awareness of several code provisions — but compliance is absolutely achievable with the right approach.
The Los Angeles Building Code (LABC) follows the California Building Code, which is based on the International Building Code (IBC). For structural applications, lumber must meet the grading requirements of the applicable code section, regardless of whether it's new or reclaimed.
For reclaimed lumber used structurally, a licensed structural engineer can assign design values based on visual grading and, if necessary, non-destructive testing. The engineer prepares a letter or stamp for the permit application certifying the material meets code requirements.
For non-structural applications (accent walls, siding over sheathing, decorative beams, furniture), code requirements are minimal. The primary concerns are fire resistance (ensuring the wood doesn't compromise fire-rated assemblies) and lead paint compliance.
Fire-related requirements are important in Los Angeles. Any reclaimed wood used in interior finish must comply with flame spread and smoke development requirements. Untreated wood generally meets Class C requirements, which is acceptable for most residential applications. For commercial spaces, fire-retardant treatment may be required.
Lead paint testing is strongly recommended for any reclaimed wood from pre-1978 structures. While not explicitly required by building code for all applications, it's required for schools, childcare facilities, and public buildings, and it's simply good practice everywhere.
Permitting for reclaimed wood projects is straightforward when you have proper documentation. We provide species identification, grade certification, and source documentation for all structural-grade reclaimed lumber we sell. This paperwork satisfies building departments in our experience.
