This guide is intended to provide you an overview of the requirements for interior remodel projects involving structural changes inside your home. For information on specific types of interior remodels, visit the project guides for attic conversions, basement finishes, bathroom remodels and kitchen remodels.
No permit is required for simple projects that only replace (like-for-like) existing cabinets, countertops, tiling, flooring in the same configuration, and/or like-for-like electrical, plumbing or ventilation fixtures. No permit is required for tearing down, replacing or repairing drywall, if limited to less than one 4-foot by 8-foot sheet.
Permits are required when your project includes the following:
- Alteration to the existing floor plan.
- Structural changes, such as adding or removing doors or windows.
- New or rerouted ductwork.
- New or relocated electrical or plumbing fixtures.
NOTE: If your project changes the use or occupancy of your home or creates an additional dwelling unit without altering the exterior of the structure, see the project guide for adding a new dwelling unit. For change of use/occupancy conversions that change the exterior of the structure see the Building/Expanding a Home page.
