Provide Percolation test results and report by a NV licensed Engineer per NRS 445A. A construction permit for a new on-site sewage disposal system shall only be issued in conjunction with a building permit application for the building it serves. A building permit application is not required to obtain a construction permit to repair an existing on-site sewage disposal system.

ADDITIONAL REQUIREMENTS:

Floodplains:

If the structure is in a FEMA floodplain or in an area determined to be a floodplain, there will be additional requirements for permit/construction. There are several options and methods of construction in a floodplain and the CSD-Engineering Division will assist you in determining which method meets your project requirements.
The services of a licensed NV Engineer or Land Surveyor will be required to complete a FEMA Elevation Certificate. The 1st part of the elevation certificate is required before a building permit is issued. The 2nd part of the elevation certificate is required at the floor joist inspection. The elevation certificate (part 2) can be used to obtain flood insurance for the structure.

Impact Fees:

Regional Road Impact Fee (RRIF): Washoe County collects the RRIF for new residences. The fee is for the increased traffic generated by new construction. This fee is collected at the time the building permit is issued or can be differed until C of O.
The Residential Park Tax is imposed on construction of apartments, houses, condos, duplexes and residential dwelling units and mobile home lots in the County. This tax rate is 1 percent of the valuation of each building permit issued or $1,000 per residential dwelling unit, whichever is less.

Prerequisite:

Architectural Committees (NRS 278.563): If the project is located in an area that has an architectural committee, the committee must be registered with Washoe County per NRS 278.564 and the State of Nevada Department of Business and Industry, Real Estate Division, Office of the Ombudsman for Commission for Common-Interest Communities and Condominium Hotels, OR have an “Exemption Certificate”. Architectural committee letter of approval is required prior to submitting your plans to the Building Program.
If project location is in Incline Village or Crystal Bay, TRPA approval or exemption is needed prior to permit being issued.

Engineering Requirements:

Structural engineering is strongly recommended. Structural engineering is required when the ground snow load (See table below) is more than 70 pounds per square foot, exceeds the prescriptive design requirements, or exceeds a 25’ length braced wall line.
