What usually changes the answer

What to ask
Call or check the website of your city or county building department before you start, and give them your address and a short description of the job.
- Is a permit needed for a tear-off? For an overlay?
- What if the roofer finds rotted decking partway through?
- How many layers are allowed?
- Who arranges the inspection?
Why it's worth asking first
Portland, Oregon's 2022 permit guide says inspections catch problems early, that buyers, realtors or lenders may require unpermitted work to be corrected before closing, and that a lack of permits and inspection approvals may void insurance. Even where no permit is needed, the work generally still has to meet code and zoning rules.
