Arlington County Building Permits & Codes
Arlington County requires structural building permits for all decks attached to a building, as well as freestanding decks higher than 30 inches above the surrounding grade. Permits are processed online through the Permit Arlington portal. Review timelines generally run 3–4 weeks.
Because lot sizes in Arlington are often compact, setback requirements, lot coverage ratios, and stormwater management guidelines are strictly enforced. Additionally, historic overlay districts in neighborhoods like Maywood require exterior modifications to match specific guidelines. LDN Decks handles the entire process — from zoning analysis and engineering layout to permit submission and inspection walkthroughs.
