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
The current West Virginia State Building Code adopted by Jefferson County: 2018 IBC, IRC, IPC, IMC, IFGC, IPMC, IEBC, and International Swimming Pool and Spa Code; 2015 IECC; 2017 ICC/ANSI A117.1; 2020 National Electrical Code; and NFPA 101 Life Safety Code (2021), with state amendments. The 2026 proposed update to 2024 editions was still in rulemaking as of August 1, 2026.
Inspection lane
Request inspections through MGO Connect or call 304-725-2998 Monday-Friday, 9:00 AM-5:00 PM, with the permit number, owner/property details, inspection type, and caller contact information. Requests made by 3:00 PM are normally performed within the next two business days; no appointment time is assigned, and work must be ready by 8:00 AM on the scheduled day.
Minor-work playbook
Buildings used primarily for agriculture or agritourism are exempt from the State Building Code after eligibility determination by the West Virginia Commissioner of Agriculture, although Jefferson County publishes a $55 agricultural-building permit fee. Residential storage sheds of 200 square feet or less with no plumbing or electricity are exempt from local code inspection, not expressly from the county permit. The county specifically requires permits for sheds, roof work, replacement windows, electrical/HVAC work, and other listed improvements; no general cosmetic-work exemption was published.
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 MGO Connect or call 304-725-2998 Monday-Friday, 9:00 AM-5:00 PM, with the permit number, owner/property details, inspection type, and caller contact information. Requests made by 3:00 PM are normally performed within the next two business days; no appointment time is assigned, and work must be ready by 8:00 AM on the scheduled day.
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
Jefferson County Office of Building Permits & Inspections 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 304-725-2998.
No fixed permit-review period is published; review starts after the submission is complete and accepted, and timing depends on workload. Inspection requests made by 3:00 PM are normally completed within two business days.

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.
