Overview of ADU Permitting in Omaha

An ADU is a secondary housing unit on the same lot as a primary residence. In Omaha, ADU approval commonly involves both zoning approval and a building permit to ensure compliance with land-use rules, setbacks, occupancy limits, and building codes. Confirm whether your lot zoning allows an ADU and whether design standards or owner-occupancy rules apply before preparing plans. See the municipal code for zoning provisions and the City Planning/Building pages for permit intake and submittal procedures Omaha Municipal Code[1] and City of Omaha Planning & Building[2].

Check zoning and overlay districts first to avoid rejected applications.

Step-by-step process

  • Pre-application zoning check: verify ADU allowance and lot standards.
  • Prepare plans: site plan, floor plans, elevations, and code compliance documentation.
  • Submit building permit application and required documents to the Planning & Building division.
  • Pay application and permit fees as determined at submission; fee amounts may vary and are listed on the City of Omaha permit pages.
  • Undergo inspections during construction and prior to occupancy to confirm code compliance.
  • Receive permit approval and final certificate of occupancy before renting or occupying the ADU.

Applications & Forms

The primary submissions are a building permit application and supporting plans. The City of Omaha Planning & Building pages list permit intake methods and requirements; specific form names or numbers are either provided on that page or through the online permit portal. If a named ADU form is required, it will be listed on the City’s permit pages; otherwise, submit a standard building permit application with ADU plans. For current forms and submission portals, consult the City of Omaha Planning & Building resources Planning & Building[2].

If your property is in an overlay or historic district, additional approvals may be required.
