Why Fairfax County Homeowners Trust LDN Decks
Fairfax County is the most populous county in Virginia with over 1.1 million residents and median home values exceeding $650,000. The county's established neighborhoods — from Vienna and McLean to Burke and Springfield — represent decades of homeownership, and many properties are now due for outdoor living upgrades as original decks reach the end of their lifespan.
LDN Decks brings Trex, TimberTech, AZEK, and pressure-treated framing experience to every Fairfax County project. We understand the county's detailed building code requirements, HOA architectural review processes, and the high standards Fairfax homeowners expect.
Fairfax County Building Permits & Codes
Fairfax County requires building permits for all attached decks and any deck over 200 square feet. Applications are submitted through the FIDO online system (Fairfax Inspections Database Online). Processing time is 3-6 weeks — longer than Loudoun or Prince William counties. Three inspections required: footing, framing, final.
LDN Decks handles the entire Fairfax County permit process including structural drawings, FIDO submission, and inspector coordination. We build to meet or exceed Fairfax County's typical deck detail specifications and address review comments when they arise.
