Omaha ADU Zoning Explained: What Homeowners Need to Know
Accessory Dwelling Units (ADUs) are becoming one of the most talked-about housing options in Omaha. Whether you are thinking about building one for family or as a rental, the first step is understanding the zoning and site rules. Omaha has made significant strides to make ADUs possible, but there are still guidelines every homeowner should know before starting.
This blog breaks down the basics of Omaha’s ADU zoning and the site development regulations that will shape your project.
What is an ADU?
An ADU (Accessory Dwelling Unit) is a secondary housing unit on the same lot as a single-family home. Think: a backyard cottage, guesthouse, garage apartment, or basement suite with its own kitchen and entrance.
They can be used for:
Housing a parent or adult child
Generating rental income
Increasing your property’s value
ADU Zoning in Omaha
Omaha’s 2024 zoning updates opened the door for ADUs, but the rules vary depending on your neighborhood. In many parts of the city, building an ADU requires a conditional use permit, which is a public approval process through the city. While that might sound intimidating, it is a navigable path that homeowners move through successfully every year.
In some districts, ADUs are allowed by-right (meaning you do not need extra approvals if your project meets the requirements), but those areas are less common for now.
Tip: Don’t let the permit process discourage you. With the right plan and understanding of your site, the conditional use permit is often just another box to check on your way to building your ADU.
Omaha ADU Site Development Rules: What Homeowners Need to Know
Beyond zoning, Omaha has specific site development regulations that affect how and where you can build an ADU on your property:
Lot Coverage: Adding an ADU allows up to a 15% increase in the maximum building coverage for your lot.
Setbacks: Detached ADUs must be at least 20 feet behind the front of your main house. Standard setbacks are 5 feet from the side yard and 8 feet from the rear, though they can shrink to 3 feet if no utility easements exist.
Height: Detached ADUs can be up to 16 feet tall.
Entrances: Street-facing entrances are limited. Exterior doors must face an alley, interior yard, or side yard, not directly toward the street.
Existing Structures: Older garages or sheds that don’t meet today’s setback or height rules may still be converted into ADUs, as long as you don’t increase their noncomformity.
Parking: No additional on-site parking is required when you add an ADU.
Driveways: Each lot is limited to one driveway per street frontage, meaning ADUs can not typically have their own driveway.
Waiver Option: Flexibility for Unique Lots and Use Cases
What if your property does not check every box or you are looking for something that would not conform to the site development rules? Omaha provides a waiver process through the Building Board of Review. That means even if your lot is not a perfect fit for the rules on paper, you may still have a path forward if you present the right design and use case. The waiver process often requires the assistance of a designer and/or general contractor to confidently navigate.
