Building permits, zoning and septic rules in Churchill County, Nevada

Yes. Unincorporated Churchill County requires permits for new residential and commercial construction, additions and alterations¹. Accessory buildings and garages under 200 square feet are listed as not requiring a permit, while prefabricated storage sheds, carports and cargo containers require one⁹. Concrete patios, driveways and wood decks generally do not require one, although a deck or patio structure 30 inches above grade does⁹. The county lists the 2024 building, residential, energy, fuel-gas, plumbing and mechanical codes with Northern Nevada amendments¹⁰. Permitted projects proceed through applicable construction inspections, with the final inspection after finish grading when the building is complete and ready for occupancy¹¹.

The Churchill County Building Department issues permits and inspects residential and commercial construction in the county's unincorporated areas³. The office is at 270 S. Maine Street, Suite A, Fallon, NV 89406; call (775) 428-0264 or email buildings@churchillcountynv.gov³. All building-permit applications go through the county's online portal³. Ask the Building Department for the fee applicable to the proposed work. Inspection requests generally need at least 24 hours' notice, and the sequence may include foundation, stemwall, slab or under-floor, rough framing, other code inspections and a final inspection¹¹.

Yes. All land in Churchill County is assigned a zoning district². The county has 10 districts in agricultural, residential, commercial, industrial and rural-resource groups². A parcel's district determines its allowed uses and required permit type, so a rural-looking tract is not unrestricted land². Setbacks vary by district; along state- and county-maintained roads with speed limits above 25 mph, an additional 30 feet generally applies unless the lot is smaller than 1.5 acres¹². Minimum parcel size depends on the district: A-5 requires 5 acres, A-10 requires 10 acres, RR-20 requires 20 acres, R-1 requires 7,000 square feet, and E-1 requires 1 acre, or 1/2 acre where water or sewer facilities are provided¹². Land divisions are also regulated under the district-specific rules¹³. Call Planning at (775)423-7627 or use CitizenServe before designing a house, accessory dwelling or land division¹⁴.

The Churchill County Building Department permits and inspects new individual septic systems and repairs in unincorporated Churchill County³. The plan-check and inspection fee for an individual residential septic construction or repair is $200⁴. A septic permit application must be complete and include a soil profile, two percolation tests and a scale plot plan⁴. Septic work has two inspections: the first when the soil-profile pit is dug and the second after completion but before anything is covered⁴. Only about 9.1% of county soils are rated without severe limitations for a conventional drain field, so obtain the site evaluation early and budget for a parcel-suitable design¹⁵. Nevada prohibits cesspools and injection wells associated with septic tanks¹⁶. Call the Building Department at (775) 428-0264 for the application and inspection sequence³.

In unincorporated Churchill County, living in an RV outside a mobile home park or RV park is generally limited to 90 days per year⁵. Longer temporary occupancy may qualify for a temporary-use permit for farm labor, a watchman, hardship or caretaker needs, or while an on-site permanent home is being built or placed; proof of need and annual renewal apply⁵. Nevada requires counties below the state population threshold to designate at least one zoning district for an accessory dwelling unit, single-family tiny house or tiny-house park, but that does not make every parcel eligible⁶. Churchill County publishes an accessory-dwelling or second-permanent-dwelling application, but allowed use and conditions still depend on the parcel^2,17.

1. Ask Planning to identify the zoning district, allowed residential use, setbacks and required land-use approval^2,12.

1. Schedule the recommended pre-application meeting, then upload the signed planning application, supporting documents, site plans and maps through CitizenServe².

1. Confirm water and wastewater early; for an individual septic system, start the county application and soil-profile review before finalizing the site plan^3,4.

1. If acting as your own builder, apply to the Nevada State Contractors' Board for the licensing exemption and submit the required disclosure⁷.

1. Submit the building-permit application through the county portal³.

1. Schedule construction and septic inspections, leaving at least 24 hours for a typical building inspection request and keeping the septic system uncovered for its completion inspection^4,11.

Start with water: Churchill County averages about 6.4 inches of precipitation a year, and severe drought appears in roughly 47.6% of years¹⁵. A domestic well generally does not require a Nevada groundwater-appropriation permit, but nondesignated basins and other exceptions may require a permit or waiver⁸. Check septic feasibility because only about 9.1% of county soils avoid severe conventional drain-field limitations¹⁵. Ask Planning to check the flood-zone status using the parcel number or address¹⁴. A temporary-use application requires legal access to the property, so confirm recorded access before relying on an RV exception¹⁸. Any driveway work inside a county right of way or road easement needs an encroachment permit, and the standard road easement is 60 feet wide; the $50 residential encroachment fee is waived for a driveway if the Road Department is notified during planning¹. For carrying costs, the effective property-tax rate is about 0.6%, with a median annual bill near $1,670¹⁵.
