Construction permits

Construction projects and repairs require a construction permit.

Before you can get a construction permit for some projects, you might need to get a zoning permit first. This could involve approval from the Planning Board or Zoning Board. Contact us to find out if zoning approval is required for your project.

Projects have different requirements, depending on the nature of the work. Before you apply, review the application forms and prepare the required materials.

We have some permit guides for common home improvement projects:


All construction projects need a construction permit. Depending on the project, you may also need a subtype application:

  • Building
  • Electrical
  • Mechanical
  • Plumbing
  • Fire protection

Based on the project, you may need to complete multiple application forms.

Here's a list of common projects and the permits required. Contact us if you aren’t sure where to start or if you don't see your project on the list.

Apply for a construction permit

Permit costs and timelines vary depending on the:

  • Type of permit
  • Project size and complexity
  • Job valuation

If you do work without a permit, you may need to pay a fine and undo the work done.


We inspect your construction project as work progresses to make sure everything is safe and meets codes and regulations.

If you don’t get inspections, your permit could be revoked and you may need to stop your project.

Turnaround times

Turnaround times for processing building permits depend on the type and complexity. We review projects to make sure they conform to local, state, and federal regulations. We have 20 days to review your application.


If information is missing or does not meet the requirements, we will contact you and let you know. You will get plan review comments. You will need to fix the error and resubmit your plans. This may extend the time frame for approval.

Tips for faster turnaround times

  • Ask us any questions you have before you submit your application. If it’s a complex project, meet with us first.
  • Use high-quality design professionals.
  • Make sure your plans reflect and comply with current building, electrical, plumbing, and energy efficiency codes.
  • Review the zoning rules, building codes, and other standards.
