Basement Finishes

If you are planning to remodel or finish all or part of your basement, you are required to submit for and obtain a building permit and inspections.

Please be aware that dumpsters and construction materials must not create an obstruction to the public.

Requirements for submitting a permit application for an addition or remodel

  1. Permit Application Form
  2. Construction Plans (see Sample Remodel Diagrams)
    1. Provide a floor plan that shows the entire basement, hash through areas not being finished or that are already finished
    2. Label the use of each room (such as "bedroom"), also label unfinished areas as "unfinished" and areas that are already finished as "existing"
    3. Show all electrical outlets, lights switches, smoke/carbon monoxide detectors
    4. Show dimensions of each window, each room and of entire area
    5. Show window well dimensions for all bedrooms (see Emergency Escape diagram for egress requirements)
    6. If adding a new walkout, please include walkout plans (see Basement Walkouts).
  3. If there is any kind of kitchen, kitchenette, or wet bar in the basement, please be aware that creating an Internal Accessory Dwelling Unit (apartment) is only allowed in certain zones, has other conditions, and requires an application and approval (see I-ADUs). If you are not creating an I-ADU, please sign the Affidavit and submit it with your Basement Finish Application. If you have any questions, please contact the City Planning & Zoning Department at 801-446-5323 or

Permit fees are based on the square footage being finished (see Fee Calculation Form). Permit fees pay for reviews in the office as well as inspections which will need to be done at the property. We will email invoices when fees are due.

Submit signed application and plans to the Building Department by email at  If your plans are too large to email, please provide a shareable link to where we can download your plans from such as Dropbox, Google Drive or other online service.

Plan review will take approximately 7-10 working days, after which we may require corrections that will need to be made to your plans. The permit will be issued after plans are approved and all fees are paid.

Basement finishes/remodels typically require three inspections, but may require others as needed (see Required Inspections). You must pass a final inspection when all work is completed. Call the Building Department at 801-446-5327 at least one business day before you wish to schedule each inspection. You may ask for an hour block of time when there will be an adult to meet the inspector at the property. When the work is completed and all inspections are approved, be sure to keep the plans, permit and inspection reports with your house records.
