ADU rules in Omaha, NE — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Omaha allows ADUs under a 2020 zoning code update, but uptake has been minimal. ADUs must comply with Chapter 55 zoning setbacks, lot coverage limits, and building permits.
Omaha updated its zoning code (Chapter 55) around 2020 to allow accessory dwelling units in residential zones. ADUs must comply with the applicable zoning district's setback requirements, height limits, and lot coverage rules from the Site Development Regulation table. ADUs require building permits and must meet all applicable building codes (2018 IRC for single-family/duplex, 2017 NEC for electrical). In practice, uptake has been extremely low — in the first three years of the streamlined process, no ADU units were produced. Many neighborhoods have HOA covenants that prohibit ADUs.
ADUs built without permits or in violation of zoning rules are subject to code enforcement, stop-work orders, and potential removal.
