Frequently asked questions

Does a garage / carport need a permit?

In most U.S. jurisdictions a garage / carport requires a building or trade permit because it affects structure, safety, or utilities. Requirements vary by state and city, so confirm with your local building department using the state and county pages on this site.

Who issues the permit for a garage / carport?

Issuance depends on the project and locality: some are handled by the city building department, others by the county, and a few by the state. The state and county pages list the responsible authority with links to the official source.

What is typically exempt when installing a garage / carport?

Minor or cosmetic work is often exempt, but the thresholds differ by jurisdiction. Some states exempt small structures under a height or area limit, while others require a permit for any electrical or plumbing connection. Check the specific state and county rules rather than assuming a blanket exemption.

How much does a garage / carport permit cost?

Fees are set locally and range widely — from a flat residential fee to a percentage of project value. Where an official fee schedule is published we list it; otherwise confirm the current fee with the issuing authority before you apply.
