Fairfax County enforces the Virginia Uniform Statewide Building Code regulations, mandating a Building Permit for most new residential and commercial construction, which includes, electrical, mechanical, plumbing, installations, and floor layout alterations; to include building additions, decks, carport enclosures, finished basements, second kitchens, bathroom and kitchen alterations. If you notice new construction, demolition of an existing structure, construction equipment or materials, or work occurring on the weekend or after hours anywhere in the county, contact the Land Development Services Department (LDS) at 703-222-0801, TTY 711. If further assistance is needed, then contact the Department of Code Compliance (DCC) to confirm whether a permit is required or was issued to the subject property address. If the permit requirement is in question, an investigation of the activity would be performed by DCC to make that determination. If the investigation reveals the work to be unpermitted, then a notice of violation would be issued requiring permits to be issued and inspections to occur. Your identity will be kept confidential. If you need to obtain a Building Permit, information is available from LDS on the Publication and Permit Library. PLUS is the County system that LDS uses for the Building Permit process and can be accessed at plus.fairfaxcounty.gov. If you have any questions about PLUS, information is available on Your LDS Guide to PLUS.
