What does an AHJ do?

An authority having jurisdiction (AHJ) is an organization, office or individual responsible for enforcing applicable codes and regulations or approving equipment, installations or procedures.

For sign installations, different authorities may oversee electrical safety, building permits and zoning requirements. Depending on the location, you may need approvals from more than one authority.

Who is the AHJ for my installation?

The relevant AHJ may be a provincial or territorial electrical regulator, a municipal department or another organization with delegated authority. The responsible authority depends on the location and the type of approval required.

Before starting work, confirm which authorities oversee your installation and what permits, inspections and approvals they require.

How should I work with the AHJ?

Contact the relevant authority early to clarify applicable requirements, particularly when installing a sign on an existing building or connecting it to existing wiring.

An existing installation may have been built under an earlier code edition. Ask the electrical authority which requirements apply to the proposed work and whether any upgrades are necessary.

Any alternative approach or deviation must follow the approval process permitted by the applicable legislation and code.
