When a permit is required
Permit triggers and exempt work for Nevada County
If the project is not on the County exempt-work list, a permit is required. Typical permitted work includes new residences, additions, remodels, garages, structures with utilities, reroofs beyond the exempt threshold, and other work subject to the California building codes and local amendments.

- Exempt Certain agricultural structures may be exempt only with site plan review and a letter of exemption from Building and Planning, and only if they meet zoning, size, setback, use, and construction limits stated in the handbook
Note: Nevada County says if a project is not on the exempt-work list, a permit is required. Exempt structures still must meet setbacks and other zoning and fire rules.
- Construction plans
- Site plans
- Truss calculations if manufactured trusses are used
- Engineering calculations if an engineer is involved
- Septic design or site plans for a new dwelling
- Completed site plan checklist
- Energy calculations where applicable
- Signed and stamped plans where applicable
- Building code
- For projects submitted on or after January 1, 2026, Nevada County requires compliance with the 2025 California Building Standards Code, including current Energy Codes, plus local amendments in the Nevada County Land Use and Development Code effective January 1, 2026.
- Permit validity
- Permits are active for one year from issuance and are eligible for one one-year extension based on justifiable cause. County policy also states permits expire if work is not commenced, or is suspended or abandoned, for 180 days at elevations of 5,000 feet and lower, and one year at elevations above 5,000 feet.
- Owner-builder
- Owner-builders may perform their own work without workers' compensation insurance only if they do the work themselves or with immediate family and no wages or contracts are involved; otherwise, with proof of workers' compensation insurance, an owner-builder may hire by the hour, use licensed contractors, or use unlicensed persons for up to $500. Owner-builder agents may need an authorization letter and owner-builder verification form.
- Contractor requirements
- The online application handout requires a licensed contractor number unless the applicant is owner-builder. The owner-builder application form states the applicant is either a California licensed contractor, the property owner, or an authorized agent, and cites the Contractors' State License Law.

Application process
Typical processing: New residences are reviewed in about 4 weeks; most other projects are reviewed in 10 days to 4 weeks depending on project size and type. The online-application handout also says initial application processing is 24-48 hours from receipt for express permits and staff intake of full-review applications.
- 01 Research parcel constraints before applying. Use the County Research page, My Neighborhood map, and zoning resources to confirm zoning, snow load, permit history, and site constraints.
- 02 Prepare the application package. For in-person submittals, bring construction plans, site plans, truss calculations if applicable, engineering calculations if applicable, and septic design or site plans for a new dwelling. For online submittals, create an Accela account, choose the Building module, enter project details, and upload plans plus calculations or miscellaneous documents.
- 03 Submit the application online through Accela Citizen Access or in person at the CDA counter.
- 04 Pay intake fees. The County requires plan check fees at application for paper submittals; online full-review applications are reviewed by staff first so fees can be calculated and then paid.
- 05 Monitor plan review status in the Citizen Access Portal and respond to corrections. The County posts workflow status, notes, and documents in the permit record.
- 06 After approval, satisfy issuance prerequisites such as site plan approval, Environmental Health approval where required, and outside fees or receipts, then pay remaining permit fees and obtain the permit card.
- 07 Schedule inspections during construction and obtain final inspection before permit expiration.
