ADU Rules in Fremont, Nebraska

No Statewide ADU Law — Fremont's Zoning Controls

Nebraska has not passed statewide ADU preemption legislation. In Fremont, the City of Fremont Zoning Ordinance governs all accessory dwelling unit permissions, and the Planning and Zoning Department is the key point of contact. Fremont is a smaller city with a stable, established residential character — primarily single-family neighborhoods — and the zoning code reflects that tradition.

Zoning Districts and ADU Permissions

Fremont's residential zoning includes standard single-family districts (R-1, R-2) and higher-density residential zones. ADUs are generally allowed as accessory uses in residential districts, subject to use standards that address:

• Minimum lot area
• Parking requirements (ADUs may require one additional off-street parking space)
• Compatibility with the primary dwelling's architecture and scale

Properties in Fremont's downtown or near major commercial corridors may be in commercial or mixed-use zones with different regulations.

Permitted ADU Types

Fremont's zoning generally permits:

• Detached ADUs: Freestanding accessory structures in the rear yard, including garage conversions and new builds
• Attached ADUs: Additions to the primary dwelling with a separate exterior entrance
• Interior conversions: Basement or upper-story units meeting habitability and egress requirements

Size and Setback Standards

Typical standards in Fremont (verify current code with Planning):

• Maximum ADU size: Often limited relative to the primary dwelling's square footage, commonly 600–800 sq ft
• Rear setback: Generally 5 feet minimum
• Side setback: Generally 5 feet minimum
• Height: Detached accessory structures typically limited to 15–18 feet at peak
• Lot coverage: Total structure footprint limits apply per district

Platte River Floodplain

The Platte River flows along Fremont's southern edge, and portions of the city — particularly near river access areas and low-lying terrain — are mapped in FEMA Special Flood Hazard Areas (SFHAs). The Platte's broad, braided channel can carry high spring flows. If your property is in a flood zone:

• Contact the City of Fremont's Floodplain Administrator (through Public Works)
• A Floodplain Development Permit is required before construction
• Finished floor elevation for new structures must meet or exceed the Base Flood Elevation (BFE)
• Substantial improvement rules apply to existing structures in flood zones

Proximity to Omaha Metro

As a community within the greater Omaha metropolitan area, Fremont residents commuting to Omaha may benefit from ADUs for extended family housing or rental income. Owner-occupancy requirements — if any — should be confirmed with the Planning Department, as these vary.

Permit Process

1. Confirm your property's zoning district with the Fremont Planning and Zoning Department
2. Verify floodplain status through the city or Dodge County GIS
3. Submit a building permit application with site plan, floor plan, and elevation drawings
4. Pay applicable permit fees
5. Schedule required inspections
6. Obtain certificate of occupancy before occupancy
