How to get a building permit in Manchester
Step 1: Prepare your documents
Most projects need a complete packet before review. Typical requirements include:
- Manchester building permit application (plus a $25 non-refundable application fee)
- Project description + estimated project cost/valuation (used to calculate fees)
- Construction drawings/plans (scope-dependent)
- Site plan / plot plan (Manchester provides a sample site plan link)
- Trade permit applications if your project includes electrical, plumbing, or heating work (Manchester lists these permit types separately)
Step 2: Submit your application
Manchester’s Building Division provides permit applications online (or use email: pcd@manchesternh.gov). If you’re unsure which permit(s) you need, start at the Building Division page (it lists what they process).
Step 3: Plan review
City staff review applications for:
- Building code compliance
- Zoning / local requirements
- Other safety items handled through the Building Division workflow
Step 4: Pay permit fees
Once approved, you’ll pay the permit fees to activate the permit.
Step 5: Post permit and begin work
Keep your permit info available on site and schedule inspections as work progresses. Manchester’s structural inspectors list office hours and direct instructions to request inspections by email, and include your permit/application number and project address.
Step 6: Close out the permit
For many projects, you’ll need final sign-off (and for some projects, a Certificate of Occupancy / final inspections).
