Homeowners don't know if their house construction details meet building codes and won't cause costly damage

Homeowners and DIYers lack reliable guidance on whether specific construction details (like wood gaps at siding-ground interface) meet building codes and won't lead to water damage, rot, or structural problems. They post on forums hoping for answers but get inconsistent advice, and hiring contractors for minor clarifications is expensive. Current solutions (forums, generic building code documents) are slow, unreliable, and don't provide confidence before costly mistakes happen.
