Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 240-313-2460; 240-313-2488 (24/7 inspection IVR).
How long might review take?
Inspection requests require at least 24 hours' notice; a complete Certificate of Occupancy is normally issued by the end of the second business day after final building inspection approval. No universal plan-review issuance time is published.
How are inspections scheduled?
All new buildings, additions, and alterations require at least 24 hours' notice before each inspection. Schedule through Citizen Access or the automated IVR at 240-313-2488, available 24/7, using the building activity and inspection-item numbers. Rough trade inspections precede framing; final mechanical and building inspections are scheduled together after final electrical, plumbing, health, and other required approvals. A Certificate of Occupancy is normally issued by the end of the second business day after final building approval when all documents and fees are complete.
Which codes and exemptions should I review?
Washington County's code pages identify the Maryland Building Performance Standards with 2021 IBC, IRC, IECC, and IEBC local amendments; 2021 IFGC, IMC, and IPC local amendments; and local electrical amendments. The same page also labels a legacy 2018 IBC/IRC/IECC/IEBC/IPC/IMC/IFGC and 2017 NEC set as current, so applicants should confirm the transition edition with the Division. New residential one- and two-family dwellings and additions must comply with the 2021 IECC residential provisions, and new qualifying homes must provide an EV-ready or EV-installed parking space. The county's residential and commercial guidance generally exempts detached non-habitable accessory structures up to 400 square feet; fences up to 7 feet; retaining walls retaining less than 36 inches unless supporting a surcharge; certain grade-level sidewalks and driveways; painting, papering, tiling, carpeting, cabinets, countertops and similar finish work; prefabricated pools under 24 inches deep; swings/playground equipment; qualifying small wall-supported awnings; and qualifying detached decks up to 200 square feet and 30 inches high. Other zoning, trade, floodplain, or accessibility requirements may still apply.
