General information, current as of 2026 — not legal advice. Confirm specifics with your local jurisdiction.
The Nebraska Public Service Commission, through its Housing and Recreational Vehicle Department. Modular units built to Nebraska's adopted codes (IRC and NEC) receive a Nebraska Modular Housing Unit label; the State Fire Marshal's Office handles building plan reviews and code enforcement. With the label, your local jurisdiction permits the site work — foundation, utilities, zoning — without re-reviewing the structure.
Yes — and Omaha is unusually permissive after its 2024 zoning change. ADUs are allowed by right in nine zoning districts (and via conditional use permit in 12 more), with no maximum size limit, no required additional parking, and the ability to rent the unit short- or long-term. Only one ADU is allowed per residential lot, and it can't be sold separately from the primary home. It can be attached, internal, or detached.
Lincoln allows ADUs but with tighter limits — an ADU can't exceed 800 sq ft or 40% of the primary home. Douglas County (around Omaha) commonly caps ADUs around 750 sq ft and requires compliance with height, setbacks, and permanent utilities. Confirm the current rule for your specific jurisdiction.
Wind and cold. Nebraska sees significant tornado/high-wind activity, so the structure is engineered to the design wind speeds (a safe room is a common add), and winters require a high-performance thermal envelope with snow-rated roofs. Seismic risk is low. PSL Modular sets the envelope and wind spec from your site coordinates.
Yes. Agricultural-region and metro (Omaha, Lincoln) workforce demand suit modular, and Omaha's permissive ADU rules make backyard units attractive. The PSC-labeled unit clears the building; your work is the site and local zoning.
PSL Modular units are permittable in all 50 states. Pick yours for the building-approval path, the ADU law, and the structural spec your site needs.
