Maryland Permit & Stamping Requirements
Requirements vary by region, code cycle, seismic zone, and wind or snow load. Here is what typically drives design for Maryland projects.
What Drives Design in Maryland
Maryland projects are governed primarily by formal plan review and special inspections.
- ✓ Special inspection program coordination
- ✓ Full MEP package for commercial filings
- ✓ Plan review comment response and expediting
Exact code edition and local amendments vary by city and county. We confirm the specific requirements for your address before drafting.
Code in effect in Maryland
Maryland's Building Performance Standards require every county and city to enforce the same model codes: currently the 2021 International Building, Residential and Energy Conservation Codes, adopted by the state on May 29, 2023 and enforced locally since May 29, 2024, with each jurisdiction adding its own amendments. The state has proposed moving to the 2024 editions; the draft rules were published June 26, 2026 and had not taken effect at our last check.
What to plan for
- ✓ Each county and city adds its own amendments, so the same project can need different details in Montgomery County than in Baltimore County.
- ✓ A move to the 2024 codes is in progress. Once the state adopts them, local jurisdictions have up to 12 months to follow, so confirm the edition your jurisdiction enforces when you submit.
- ✓ Buildings owned by the state follow a separate Maryland Performance Code rather than the local standards.
Code information last verified October 2026. Codes change, so we confirm the edition in force for your address before drafting.
Frequently asked questions about Maryland permits
Which code applies to my Maryland project right now?
The 2021 International Codes as adopted by the state and amended by your county or city. A move to the 2024 editions has been proposed, so we confirm the edition your jurisdiction enforces before drafting.
Do Maryland counties change the state code?
Yes. The state sets the model codes, and each county and city adopts them with its own amendments and enforces them. Your local building department reviews the drawings.
