No match yet. Send us the address and we will tell you what that building department asks for.
Two different questions. “Does the code require a Manual J?” is not the same as “Will the permit office ask to see it?” Many jurisdictions adopt the code requirement but collect the report only for new construction or added ductwork. Each page separates the two, links the source, and shows the date we verified it.
