Do you need a building permit in Washoe County, Nevada?

Yes, for the work the county's rule covers. Constructing or erecting a building or structure over 200 square feet in unincorporated Washoe County requires the appropriate county building permit1. Washoe County Code Chapter 100 establishes the county's building codes, although the reviewed code page still lists the 2018 International Building Code and related codes10. The Building Program's newer notice says the 2024 ICC code editions and the 2023 NEC apply to new permit submittals11. Permitted work is subject to inspection by the building official; required stages include footing and foundation, under-floor work, framing, insulation, gypsum board and final inspection, among others specified by code12. The permit holder must call when work is ready, provide access and wait for approval before proceeding past successive inspection points13. A regulated building cannot be used or occupied until the building official issues a certificate of occupancy after inspection14. These county rules apply in unincorporated Washoe County; Reno and Sparks have their own codes and regulations2.

Who is the Washoe County building department, and how do you reach them?

The Washoe County Building Program provides plan-check and inspection services for county-adopted construction standards11. Reach the Building Program at (775) 328-2020 or [email protected], or visit 1001 E Ninth Street, Reno, NV 8951211. The county page links applicants to the online permit portal at www.onenv.us and lists front-counter hours from 8 a.m. to 4:00 p.m., Monday through Friday11. Permit fees depend on the project, but the reviewed county fee rule gives one concrete renewal example: renewing a building permit costs $45 plus 10% of the original building-permit fee and subfees, subject to the stated exclusions15. For zoning verification and land-use applications, contact the Planning Program at 775.328.6100 or [email protected], at 1001 E. Ninth Street, Building A, Second Floor, Reno, NV 8951216.

Does Washoe County have zoning, and what does that mean for RVs, tiny homes and setbacks?

Washoe County administers land-development and zoning regulations in unincorporated Washoe County, while Reno and Sparks have their own codes and regulations2. The unincorporated county rules include site- and area-specific zoning regulations17. Lot size and setbacks therefore depend on the parcel's jurisdiction and regulatory zone rather than one countywide rural standard62. The reviewed standards list minimum lots of 8 acres in LDR, 4 acres in MDR, 2 acres in HDR and 35,000 square feet in LDS, but the county calls the table a general guide and directs owners to Planning for parcel-specific confirmation6. We could not confirm a general minimum dwelling size, lot-coverage limit, temporary-camping rule or county-specific tiny-home occupancy rule. Nevada nevertheless requires a county of Washoe County's size to designate districts for tiny houses used as accessory dwellings, single-family homes and tiny-house parks, while allowing additional local requirements18. For unincorporated land, ask county Planning for the regulatory zone, allowed use, setbacks and occupancy conditions before designing or buying16.

How do septic permits work in Washoe County?

Northern Nevada Public Health Environmental Health Services permits and regulates on-site sewage disposal systems under the Washoe County District Board of Health, and a new-system construction permit is issued with the building permit3. The agency says the first planning step for a new residential septic system is a test-trench inspection and that the septic design must be permitted with the building permit19. Reach Environmental Health Services at 775.328.2003 or [email protected], at 1001 E. 9th Street, Building B, Reno, NV 8951219. Only about 6.9% of county soils are rated without severe limits for a conventional septic drain field, so make the test trench and system design part of due diligence rather than assuming a standard field will work20. Nevada prohibits cesspools, but that statewide rule does not answer whether another off-grid sanitation method would be approved on a particular Washoe County parcel21. We could not confirm a county septic-inspection schedule, so ask Environmental Health Services about inspections for the proposed system19.

Can you live in an RV or tiny home on your land in Washoe County?

The reviewed research does not establish a general yes-or-no rule for living in an RV on private land in unincorporated Washoe County. Ask the Washoe County Planning Program whether the parcel's regulatory zone permits the proposed RV use and what occupancy conditions apply16. Tiny houses have a clearer state framework but still require parcel-level zoning review: Nevada requires qualifying counties to designate zoning districts for tiny houses as accessory dwellings, single-family residences and tiny-house parks, and local ordinances may impose additional requirements18. A tiny house without a permanent foundation may receive a certificate of occupancy tied to a specific parcel; moving it requires a new certificate of occupancy22. Do not substitute the manufactured-home rule for the tiny-house answer. Manufactured homes are allowed as primary dwellings on residentially zoned property, while secondary manufactured dwellings require administrative review, must be no more than 50% of the main dwelling and cannot exceed 1,500 square feet23.

How do you build a home in Washoe County, step by step?

  1. Ask Planning to confirm the regulatory zone, allowed dwelling type, lot size and setbacks for the parcel166.
  1. If the home will use septic, arrange the test-trench inspection with Northern Nevada Public Health before finalizing the site plan19.
  1. Resolve water service or a domestic well; Nevada generally allows domestic wells without an appropriation permit up to 2 acre-feet per year, but requires a waiver where qualifying public water service is available7.
  1. Submit the building-permit application and plans through the county's online portal11.
  1. Permit the new septic system alongside the building permit3.
  1. Obtain an NDOT encroachment permit and approved traffic-control plan before driveway work in state highway right-of-way24.
  1. Call for each required building inspection and do not conceal or advance covered work before approval1213.
  1. Obtain the certificate of occupancy before using the completed regulated building14.

What should you check before buying land in Washoe County?

Water comes first: Nevada generally does not require an appropriation permit for a domestic well using no more than 2 acre-feet per year, but a waiver is required before drilling where qualifying public water service is available7. Septic feasibility is equally important because only about 6.9% of county soils are rated without severe limits for a conventional drain field20. Ask for a test trench before relying on a building envelope19. Check the parcel's regulatory zone and exact development standards; published rural minimum lot sizes vary from 2 to 8 acres among the reviewed rural zones6. For access onto a state highway, budget for an NDOT permit whose fee varies by permit category; a site plan or traffic study may also be required24. Ask the county to review flood exposure because its Engineering and Capital Projects Division reviews development in FEMA special flood hazard areas25. Finally, the county's median property-tax bill is about $2,297 per year, while the effective rate is about 0.5%926.

Watch-outs

  • We could not confirm a general minimum dwelling size, lot-coverage limit or exact parcel setbacks; get the parcel-specific standards from Planning before designing16.
  • We could not confirm a general private-land RV occupancy or temporary-camping rule for unincorporated Washoe County; ask Planning before relying on an RV as temporary or permanent housing16.
  • The Building Program says the 2024 ICC code editions and the 2023 NEC apply to new permit submittals; confirm the applicable edition for an older or already-filed project11.

Water rights & wells in Washoe County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Nevada’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt up to a limit

A single-family domestic well is exempt from a water-right permit up to 2 acre-ft/yr statewide, but in a State-Engineer-designated basin you must obtain approval before drilling, the State Engineer may bar new domestic wells where a municipal supplier is available, and in the most stressed basins (e.g. Pahrump) a new domestic well requires relinquishing 2.0 acre-ft of existing water rights.

Limit: 2.0 acre-ft/yr single-family domestic (NRS 534.180); 0.5 acre-ft/yr floor if curtailed in a critical management area
