Important

​It is imp​ortant to keep in mind the following when you are assessing whether the proposed work requires a building permit:

1. Work exempt from a buil​ding pe​rmit is not necessarily exempt from a mechanical, electrical or plumbing permit. Review the other dropdowns on this webpage for more information about those types of permits.
2. Local land-use (planning/zoning) laws must always be considered FIRST. The building code tells you how to construct something while the local laws will tell you if you can construct something.
3. Always start the discussion early with the local land-use authorities. There may be other local requirements that must be met prior to consideration of building.
4. Work not meeting all parameters specified by a particular building permit exemption will require a local building permit.
