Authority Having Jurisdiction support in Wisconsin
The AHJ (Authority Having Jurisdiction) is the entity responsible for approving ERRCS installations and verifying ongoing compliance. For most buildings, the AHJ is the local fire marshal or fire department. The AHJ reviews system designs, conducts or witnesses testing, and issues approvals needed for certificate of occupancy. Different AHJs may have varying requirements, making it essential to understand your specific jurisdiction's expectations.
BDA Systems supports owners, contractors, and technical teams throughout Wisconsin. We align project scope with local AHJ expectations, adopted code language, and the practical realities of getting from failed testing to final approval.
