Zoning, building permits and septic rules in Fernley, Nevada

The City of Fernley, Nevada, in Lyon County, regulates development inside city limits under its own Development Code, Title 321. Building permits inside the city come from the City of Fernley's Building Division, not Lyon County2. We could not confirm who issues septic permits inside city limits, so ask Lyon County's Building Department before designing a system.

Does Fernley, Nevada have zoning?

Yes. Land inside Fernley city limits is governed by the city's own zoning and development rules, published as Fernley Municipal Code Title 32, the Development Code1. Lyon County's separate land-use code, Title 15, covers only unincorporated Lyon County, so its district standards do not apply to a lot inside Fernley8.

We could not find the current numeric standards for Fernley's residential districts, so we cannot give minimum lot sizes, setbacks, minimum home sizes or height limits for the city. We also could not confirm the city's rules on RVs, tiny homes, manufactured homes or accessory dwelling units. Ask the City of Fernley Building Division for the zoning district of the exact parcel before you make an offer9.

Do you need a building permit in Fernley, and who issues it?

Inside Fernley city limits, building permits are handled by the City of Fernley, which publishes residential and commercial permit applications and a residential new-construction checklist2. That checklist calls for plans, water and sewer prepayment where applicable, and a completed utility connection form2. The permit desk closes at 4:00 pm daily for submittals9.

We could not find an official statement of exactly which work is exempt from a city permit, so assume a house, addition or repair needs one and ask the Building Division about smaller projects. Lyon County's building permit rules cover unincorporated land only, so the county's 200-square-foot accessory-structure exception should not be assumed to apply inside Fernley10.

Fees are published by the city. Each permit carries a $25 processing fee, plan review adds 65% of the building-permit fee, and a manufactured or modular home permit is $5003.

How do septic permits work in Fernley?

We could not confirm who issues septic permits for a lot inside Fernley city limits11. What the city does publish is a sewer rule: sewage may not be discharged into the city system until an application is filed and connection fees are paid, and installers of water or sewer connections must be licensed11.

For any dwelling not connected to community sewer, Lyon County's guide requires its own individual sewage disposal system and approval from the administrative authority before it is built12. That guide names the Lyon County Building Department as the county program7. Whether it handles lots inside the city is unconfirmed, so call the Lyon County Building Department and the City of Fernley Building Division before buying a lot without sewer13.

Soils matter too: about 9% of Lyon County soils are rated not limited for a conventional drain field, so expect a site evaluation on many lots14.

Can you live in an RV or tiny home in Fernley?

We could not confirm the City of Fernley's rules on long-term RV living, temporary camping or tiny homes on private lots, and the city's Development Code should be checked parcel by parcel with the Building Division9.

Do not borrow the county's answer. Lyon County prohibits motor homes, travel trailers and tiny homes classed as recreational vehicles as residences, but that rule is written for unincorporated Lyon County15. Nevada law also lets a city or county adopt a tiny-house zoning ordinance, so the answer inside Fernley depends on what the city has adopted16.

Building a home in Fernley: the steps, in order

  1. Ask the City of Fernley Building Division for the parcel's zoning district under Title 321.
  2. Settle water and sewer: confirm whether the lot connects to the city system, and complete the utility connection form2.
  3. If the lot is in a flood hazard area, include the flood hazard boundary and a FEMA elevation certificate with your plans17.
  4. Submit the building permit application and plans; if you will build for yourself, ask about the owner-builder exemption, which the city describes as covering conventional wood-frame construction under the International Residential Code6.
  5. Pass the required inspections; the final inspection comes only after all permitted work is complete4.
  6. Obtain the certificate of occupancy before anyone uses or occupies the building5.

What stays with Lyon County, and what to check before you buy in Fernley

Outside Fernley city limits, Lyon County's rules apply instead. Read the Lyon County page for unincorporated land, where the county requires building permits and runs its own zoning18.

Before buying inside Fernley, check the parcel's zoning district, whether city sewer and water reach it, and whether it lies in a flood hazard area17. Lyon County figures give context: its effective property tax rate is 0.5%19, and the area receives about 8 inches of precipitation a year20. The nearest city of 100,000 or more is about 50 miles from the county center21.

Watch-outs

  • We could not confirm who issues septic permits inside Fernley city limits; call the Lyon County Building Department and the City of Fernley Building Division before buying a lot without city sewer7.
  • Lyon County's ban on RVs and RV-type tiny homes as residences applies to unincorporated land; Fernley's own rule on RV living is unconfirmed15.
  • The city's permit desk closes at 4:00 pm daily for submittals9.
