How to apply for a residential building permit

Applying for a residential building permit is straightforward once you know the sequence. Most counties follow the same general process, with minor variations in form names and submittal channels. Here is what to expect. Step one is preparation. Before you go anywhere near the building department, write a one-paragraph description of the work, gather a site plan or plot survey of your property, and prepare a set of drawings. For a kitchen remodel, the drawings can be hand-sketched plans showing existing and proposed layout. For an addition or a new structure, you will typically need stamped drawings from a licensed design professional. Confirm that any contractor you intend to use is licensed in your jurisdiction and bring their license number with you. Step two is intake. Most counties accept residential applications at the building department counter, online through a permit portal, or by email. Bring two sets of plans if you submit in person — one for the reviewer and one for the field. The intake staff will assign your project a permit number, log it in the system, and route it to the appropriate reviewer. Step three is plan review. A reviewer will check your plans against the adopted building, electrical, plumbing, and mechanical codes, and against the local zoning ordinance. For straightforward residential work, plan review typically takes between five and twenty business days. The reviewer may issue comments asking for clarifications, additional drawings, or revised energy code calculations. Respond to comments promptly to keep the project moving. Step four is permit issuance. Once the plan check is clear, you pay the permit fee and the building department issues your permit card, which must be posted at the job site in a visible location. Work cannot begin until the permit is issued. Step five is inspections. As construction progresses, you will request inspections at defined milestones — typically footing, framing, electrical rough-in, plumbing rough-in, mechanical rough-in, insulation, and final. Inspections are scheduled by phone or through the permit portal, usually with at least one business day of notice. Step six is the certificate of occupancy. After the final inspection passes, the building department issues a certificate of occupancy or a final approval document. Keep this with your property records — future buyers, lenders, and insurers will ask for it.
