What is a building permit?
A building permit is a document of authorization issued by a local government when an individual or company wants to build a new structure or begin construction on an existing structure for expansion or repair. Moving, demolishing or converting a structure also may require a building permit.
When an individual or company files an application for a building permit, the corresponding local government agency reviews the application to make sure the proposed changes comply with all local zoning laws, land use standards and construction ordinances. While each municipality has its own unique set of laws, the government agency typically will ensure the proposed construction does not cause problems with:
- Structural integrity.
- Fire resistance.
- Proper exiting.
- Health concerns.
- Water and sewer lines.
- Extension of electrical service.
- Industrial waste.
The applicant also may need to obtain permits to cover other aspects of the construction, including electrical, mechanical, plumbing, concrete or development.
