Before a contractor can pour a foundation or open a wall for electrical work, the local building department must issue authorization. That authorization is a permit. Permits ensure that proposed work meets code and will be inspected.

Different permits cover building, electrical, plumbing, mechanical, and demolition work. Applications typically include plans, fees, and contractor information. Work done without required permits can result in fines, stop-work orders, or difficulty selling the property later.

The permitting process adds time and cost but also provides a record of compliant construction. Owners should confirm that major past renovations were properly permitted. Expedited or over-the-counter permits exist for simple jobs in some jurisdictions. Complex projects may require multiple reviews and public hearings.

A permit is the city’s way of saying the work is allowed to proceed under its rules.
