Residential Garages

detached garage This webpage provides guidance on applying for residential garage permits. Please review this information before applying for your permits.

General Rules

  • Homeowners can apply for building permits without a contractor, but will need to meet specific eligibility criteria. Review the homeowner permits page for more information.
  • If your project includes a new or modified driveway connection or curb cut, city transportation engineers will look at the quality of the right-of-way (sidewalks, curb ramps, and alleys) adjacent to your lot to ensure neighborhood infrastructure is safe and accessible for all residents. Please be aware that this could require you to make improvements to the public right-of-way adjacent to your lot.


Construction Permits

All garages need zoning, building, and sewer use and drainage permits (SUDP). Projects that upload all of the information required for these three permit types (zoning, building and SUDP) with their initial online application can receive a simultaneous review.

Scroll down for a list of items to upload with your application.

Trade Permits

Depending on your project, you may also need trade permits, such as electrical, plumbing, or mechanical permits if you are adding light, heat or A/C, or water to the garage. These can be applied for at any time, and in most cases, are issued online as quick permits. Find out what qualifies as a quick permit.

Special Situations

Landmarks and Historic Districts

All garages that are located in a historic district or a designated landmark will require a certificate of appropriateness, meaning the project's design has been reviewed by Landmark Preservation and is appropriate for the historic nature of the property. It is highly recommended that you obtain this certificate before applying for building and zoning permits.

Learn more about meeting design guidelines for landmark properties.


If your property is along a designated parkway and the project encroaches on the parkway setback, you will need to download an Exception Request form (located under Contact the Parkways Team on the Parkways webpage) and email it to

If there are trees located in the public right-of-way, or trees requiring protection in the primary street setback or side street setback, you will need to contact the Office of the City Forester at (720) 913-0651 or
