Nebraska

Nebraska communities are beginning to adopt accessory dwelling unit policies to address local housing needs. Lincoln and Omaha have updated their zoning codes to make it easier for homeowners to add a secondary unit. ADU Pass helps Nebraska property owners handle the permitting process.

State ADU details

State ADU law

Nebraska has enacted a partial-preemption framework through the Municipal Density and Missing Middle Housing Act (LB 866, 2020), codified within Neb. Rev. Stat. § 19-5501 et seq. LB 866 requires Nebraska cities to either adopt their own affordable-housing action plan by deadline (larger cities by January 2023, smaller cities by January 2024) or fall under a default state-mandated plan that effectively ends single-family-only zoning, allowing missing-middle housing types (duplex, triplex, fourplex, townhouse, ADU) in currently single-family-zoned areas. The Act does NOT include a stand-alone, by-right ADU mandate that overrides every city's zoning; LB 1166 (2024, Sen. Wayne / referred to Urban Affairs Committee) would have done that — requiring municipalities to allow at least one ADU by right on any single-family lot — but the bill stalled in committee after a contentious 2024-01-30 hearing and has not advanced. The 2025-2026 legislative session has continued to debate ADU preemption (carryover discussions and revised vehicles) but no statewide ADU-only preemption bill has cleared the legislature as of 2026-04-26.

State financing programs

Nebraska Investment Finance Authority (NIFA), the state housing finance agency, does not operate an ADU-specific loan or grant product as of 2026-04-26. NIFA's homebuyer programs (NIFA Homebuyer Assistance Program with down-payment and closing-cost assistance, plus the standard NIFA First Home and Military Home programs) can be used on a primary residence with an existing or planned ADU when the underlying mortgage program criteria are met. NIFA's Workforce Housing Pilot Program (created 2016) provides competitive financing or credit enhancement for housing developments in qualifying counties and could touch ADU-style units within larger workforce-housing projects. NIFA also passes through the federal Low-Income Housing Tax Credit and administered LIHTC Pandemic Gap Funding for affordable rental developments, neither of which is a homeowner-facing ADU instrument.

State insurance regimes

Nebraska does NOT operate a FAIR Plan or any state residual property-insurance market as of 2026-04-26. Property-insurance regulation falls under the Nebraska Department of Insurance (Neb. Rev. Stat. ch. 44). Coverage for owner-occupied dwellings, dwelling-fire policies for rented properties, and accessory-structure endorsements is entirely a function of the admitted private market, with surplus-lines carriers stepping in for risks the admitted market declines. Nebraska is in the heart of Tornado Alley; Omaha, Lincoln, Grand Island, Kearney, and Hastings see frequent hail and tornado losses. Wind/hail percentage deductibles of 1-5% of Coverage A are common, especially for roofs over 15 years. The Nebraska Administrative Code Title 210 Chapter 60 governs claim-settlement practices, including the matching regulation (§ 010.01(B)) which requires insurers to replace materials so as to maintain a reasonably uniform appearance — relevant to ADU and primary-dwelling siding/roof claims. Nebraska is a 'file-and-use' rate state where carriers can market premiums without prior approval, contributing to comparatively volatile renewal pricing in tornado-prone ZIPs.

State housing programs

Nebraska does not operate a statewide pre-approved ADU plan catalog, statewide impact-fee waiver statute, statewide streamlined-review mandate, or per-ADU rebate / incentive program as of 2026-04-26. The Municipal Density and Missing Middle Housing Act (LB 866) is the closest state-level ADU-touching policy: it requires either a local action plan or fallback to a default plan that legalizes ADUs and other missing-middle types in single-family zones. The Affordable Housing Trust Fund administered by the Nebraska Department of Economic Development funds local affordable-housing initiatives but does not target ADU construction directly. The Rural Workforce Housing Investment Fund (Neb. Rev. Stat. § 81-12,193) provides matching grants for workforce-housing projects in non-metro counties; some recipient projects have included ADU-style units.

Known state issues (2)

  • legislative-session (since 2024-01) — Nebraska homeowners cannot rely on a stand-alone statewide ADU mandate. The LB 866 default-plan mechanism is the operative state-floor instrument and depends on whether a city has filed a qualifying local action plan. (source)
  • other (since 2023-01) — ADU owners face steeper insurance pricing and stricter underwriting than ten years ago; an aging primary-dwelling roof or prior hail claim can drive non-renewal that affects ADU coverage as well. (source)
Federal (United States) — ADU-relevant rules and programs

Federal ADU law

The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.

Federal financing programs

Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.

Federal tax credits

There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.

Federal housing programs

HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
