FIPS 24031
Article I · County Baseline

The county inherits from the state. And adds local rules.

2018 International Building Code and related 2018 International Codes with local Montgomery County amendments.

Montgomery County DPS handles permitting for the entire county, including most incorporated municipalities like Rockville and Gaithersburg, though some cities maintain their own planning and zoning authority. The county utilizes a centralized eServices portal for all permit applications. Geographic overlays include specific requirements for the Agricultural Reserve, historic districts, and mandatory forest conservation areas.

The county enforces a strict Forest Conservation Law that requires a forest conservation plan or exemption for most development projects involving land disturbance.

How this fits with the state

The state authority here is Maryland Home Improvement Commission; Maryland Department of Labor. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
