Permit glossary
Permit language is full of terms that vary by jurisdiction. These plain language definitions explain the words you will run into on PermitNotebook and on official permit pages.
- Building permit
- Official authorization from your local government to construct, enlarge, alter, or demolish a structure. It triggers plan review and inspections so the work meets the adopted building code.
- Zoning permit
- Approval that a structure or use complies with local zoning rules such as setbacks, height limits, and allowed uses. A project can need a zoning permit, a building permit, or both.
- Trade permit
- A separate permit for electrical, mechanical (HVAC), or plumbing work. These are often issued apart from the building permit and sometimes by a different agency.
- Setback
- The minimum required distance between a structure and a property line, street, or other feature. Setbacks are set by local zoning.
- Accessory structure
- A detached structure that is secondary to the main home, such as a shed, detached garage, or gazebo. Many codes exempt small accessory structures from a building permit below a size threshold.
- International Residential Code (IRC)
- A model code for one and two family homes published by the International Code Council. Most states adopt a version of the IRC, often with amendments, as the basis for their residential building code.
- International Building Code (IBC)
- The model code published by the International Code Council for commercial buildings and larger multifamily structures.
- Plan review
- The jurisdiction examining submitted drawings and documents to confirm code compliance before it issues a permit.
- Inspection
- A visit by the jurisdiction at set stages of a project to verify the work matches the approved permit and the code. Passing the required inspections is needed to close out a permit.
- Certificate of occupancy
- A document issued after final inspections confirming a building or addition is complete and safe to occupy.
- Variance
- An approved exception to a zoning requirement, granted when strict application would create an unusual hardship.
- Like for like replacement
- Replacing equipment or a fixture with the same type and size, for example a water heater for an identical water heater. Some jurisdictions exempt like for like replacements from a permit.
- Right of way
- Public land, often along a street or sidewalk. Work that affects the right of way, such as a new driveway apron, usually needs a separate permit.
- Permit expediter
- A professional who manages the permit application and approval process on your behalf, common on larger or time sensitive projects.
