How long might review take?
Most applications are reviewed and issued within 10 business days; some may be issued on the date of application. Building permits are valid for one year, require construction to begin within 12 months, and become invalid if work is suspended or does not progress for six months after starting.

Call Building Services at 410-638-3366 before 3:00 p.m. for a next-business-day building inspection; requests after 3:00 p.m. are scheduled for the second business day. The permit number is required. Electrical inspections use 410-638-3363, plumbing/mechanical/fuel gas 410-638-3215, and well/septic 410-877-2300. Approved plans and the permit must remain on site, and work must not be covered before inspection. Final approvals lead to a Use and Occupancy Certificate; $50 reinspection fees must be paid before issuance.
Which codes and exemptions should I review?
For applications made on or after May 20, 2024, Harford County enforces the 2021 International Building Code, International Residential Code, International Mechanical Code, International Energy Conservation Code, International Existing Building Code, International Swimming Pool and Spa Code, International Plumbing Code, and International Fuel Gas Code, all with local amendments. The county also enforces the 2023 National Electrical Code, 2024 NFPA 1 Fire Code, 2024 NFPA 101 Life Safety Code, Maryland Rehabilitation Code, Maryland Accessibility Code, and applicable Maryland State Fire Code amendments. Harford County publishes no single broad cosmetic-exemption list and says a building permit or zoning certificate is generally required to construct or alter any principal or accessory structure, including sheds, fences, swimming pools, and finished basements; to demolish or move a structure; change use; or install or alter regulated equipment. The county's residential information indicates a shed under 200 square feet or a pre-built shed may not require construction plans, but zoning/permit applicability should be confirmed with the Permit Center. Interior-only work does not require a site plan with the application, which is not itself a permit exemption.
