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
2021 Virginia Uniform Statewide Building Code, effective January 18, 2025, including the 2021 Virginia Construction Code, 2021 Virginia Residential Code, 2021 Virginia Existing Building Code, 2021 Virginia Property Maintenance Code, 2021 Virginia Energy Conservation Code, 2021 Virginia Mechanical Code, 2021 Virginia Plumbing Code, 2021 Virginia Fuel Gas Code, and 2020 National Electrical Code.
Inspection lane
Request inspections through the SmartGov portal, by calling 804-769-4969, or by emailing permits@kwc.gov. Requests received before 8:00 a.m. are eligible for same-day inspection, although workload may require a later day and timed inspections are not accepted. Provide the permit number, address, owner, contractor, inspection type, and callback number; the original approved plans must be on site.
Minor-work playbook
Virginia's statewide exemptions include qualifying low-voltage wiring; detached one-story tool/storage sheds, playhouses, and similar accessory structures not exceeding 256 square feet; qualifying tents up to 900 square feet with fewer than 50 occupants; fences up to 7 feet unless serving as a pool barrier; low retaining walls; and ordinary cosmetic or maintenance work such as painting, wallpapering, floor finishes, cabinets and trim, and specified replacement work. Zoning and other applicable requirements remain in force.
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
Request inspections through the SmartGov portal, by calling 804-769-4969, or by emailing permits@kwc.gov. Requests received before 8:00 a.m. are eligible for same-day inspection, although workload may require a later day and timed inspections are not accepted. Provide the permit number, address, owner, contractor, inspection type, and callback number; the original approved plans must be on site.
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.

Project questions
King William County Building Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 804-769-4969.
N/A. The county states that plan review takes time and applicants should not expect same-day permit issuance.

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.
