Building permits in Portsmouth are issued by the Permits & Inspections Division. Portsmouth enforces the 2021 VUSBC.
This guide covers what requires a permit, how to apply, fees, trade permits, and inspections in Portsmouth.
Portsmouth is an independent city in the Hampton Roads region, across the Elizabeth River from Norfolk. The city handles all its own permitting, with several historic districts requiring additional review.
What requires a building permit in Portsmouth?
Under the 2021 VUSBC, a building permit is required for most construction activities:
Permit required
- New construction, additions, and alterations
- Structural modifications
- Reroofing, windows, siding changes
- Electrical, plumbing, and mechanical work
- Decks, pools, fences, and accessory structures
- Change of occupancy
- Demolition
- Sign installations
Typically exempt
- Painting, flooring, and cosmetic work
- Detached accessory structure ≤ 256 sq ft
- Retaining walls ≤ 4 ft
- Same-type fixture replacements
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Portsmouth trade permits
Electrical, plumbing, and mechanical permits filed separately. DPOR-licensed contractors required.
Electrical permits
Required for service upgrades, panel work, solar PV, and wiring — DPOR-licensed electrical contractor required.
Plumbing permits
Required for plumbing, repipes, water heaters, and gas work — DPOR-licensed plumber required.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, and ductwork — DPOR-licensed mechanical contractor required.
Miscellaneous & specialty
Historic district projects may require additional design review. Sign and demolition permits follow separate processes.
Verify your contractor's license. Virginia requires a state contractor license issued by the Virginia Department of Professional and Occupational Regulation (DPOR) for any project valued over $1,000. Licenses are classed by project value: Class A ($120,000+ per project), Class B ($10,000–$120,000), and Class C ($1,000–$10,000). Each class requires specific experience, education, and financial qualifications. Homeowners may perform work on their own primary residence without a contractor license, but all permits and inspections still apply. Verify licensure at dpor.virginia.gov.
