When Does an Omaha Basement Room Count as a Bedroom?

The City of Omaha's 2018 IRC amendments, effective July 1, 2020, define a sleeping room as any room over 70 sq ft with built-in closet space that typically could be used as a bedroom. Each one needs an emergency escape opening, and Omaha removed the code's sprinkler exception for basement bedrooms.

How does Omaha's code define a basement bedroom?

Three things together make a sleeping room in Omaha: the room is larger than 70 sq ft, it has built-in closet space, and it could typically be used as a bedroom. Rooms used only for cooking, eating, family living or gathering are left out, as are bathrooms, toilet rooms, halls, storage, utility and workshop space, and unconditioned space. An office with a built-in closet is the classic gray area. If it passes the size and closet test, plan as though it is a bedroom.

Finishing a basement: when an opening is required

• Remodeling an existing basement with no new sleeping room: no escape opening is required by that work (R310.6 as kept in Omaha's amendments).
• Creating a new sleeping room in an existing basement: it needs its own escape opening under R310.1.
• A new basement, for example under an addition: it needs an escape opening unless it reaches one through an existing basement or has a bedroom with its own (R310.5).
• Sprinklers: the model code lets a sprinklered home skip openings in basement bedrooms. Omaha deleted that exception, so the opening is still required.

Basements used only for mechanical equipment and no bigger than 200 sq ft are exempt from R310.1.

Which code edition applies

Nebraska law adopts the 2018 International Residential Code as the state building code (Neb. Rev. Stat. 71-6403) and lets cities enforce their own version if it conforms with it (71-6406). The City of Omaha's Permits and Inspections division lists the 2018 IRC as its effective residential code, with amendments in chapter 43 of the Omaha Municipal Code. Code editions do get updated, so confirm the edition and any changes with the city when the permit is issued.

Buying or selling with a basement bedroom

If a listing counts a basement room as a bedroom, check it against the test above and measure the window: 5.7 sq ft clear, 24 in high, 20 in wide, a sill no higher than 44 in. If you are the seller and it falls short, the options are an egress window installation or describing the room as something other than a bedroom. A well and cover that work in winter round out the job, and the typical egress window costs show what each piece runs.
