  4. Homeowner affidavit if the homeowner/occupant proposes to complete any of the work themselves (must own and occupy the property as primary residence to qualify)

A separate remodel permit is required for any structural changes proposed for a basement finish. This includes new exterior openings, changes to existing exterior openings, removal of interior walls, or removal/relocation of mono-posts or other supports. Engineering is required for these changes. A site/plot plan is required when new exterior openings are proposed.


  • Finished basements are not eligible to be utilized as a separate or accessory dwelling unit (apartment or rental unit) unless it was designed and approved as such. There are many UDC requirements and building code requirements for separate dwelling units that are not met by a typical basement finish.
  • Water heater/furnace replacement cannot be included in basement finish permit. Separate permit is required.
  • A separate permit and engineering are required:
    1. if any new openings are proposed in the exterior walls
    2. if any mono-posts or other supports are proposed to be moved or removed
    3. if any interior walls are proposed to be moved or removed
