Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
Effective January 1, 2026: 2024 IBC, IEBC, IECC, IFGC, IMC, IRC, ISPSC, UMC, and UPC; 2023 NEC; 2024 Northern Nevada ICC Amendments; and 2024 Lyon County Amendments. The county design criteria also specify seismic D2/D, frost depth of 18 or 24 inches by elevation, and county wind/snow criteria.
Inspection lane
Inspection requests must reach the Yerington office by 4:00 p.m. on the working day before the requested inspection; Monday inspections must be requested by Friday. Keep approved plans, permit card, and prior inspection reports at the job site. A recall fee currently listed is $80.
Minor-work playbook
The application covers residential, commercial, accessory, manufactured-home, electrical, mechanical, plumbing, demolition, grading, fence, pool/spa, reroof, and related work. The reviewed county pages do not provide a complete minor-work exemption list; contact the Building Division for project-specific exemptions.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
Inspection requests must reach the Yerington office by 4:00 p.m. on the working day before the requested inspection; Monday inspections must be requested by Friday. Keep approved plans, permit card, and prior inspection reports at the job site. A recall fee currently listed is $80.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
