Fence Installation Permits in Maryland
Fences are governed mainly by local zoning, not a statewide building permit. Cities set height limits (commonly 3-4 ft in front yards and 6 ft in back and side yards), setbacks, and corner sight-line rules, and many require a zoning permit for any fence. Most jurisdictions exempt fences up to 7 ft from a building permit (IRC R105.2) and require one above that. Replacing a fence at the same height, material, and location usually needs no permit; a fence used as a pool barrier always does.

Maryland Building Performance Standards (IBC/IRC-based)
Maryland sets statewide Building Performance Standards through the Department of Labor, which local jurisdictions must adopt and may amend. Fences are handled through local zoning and accessory-structure rules, so the permit trigger differs by county.
Who Sets the Rules
What's Different in Maryland
County rules diverge a lot in Maryland. Baltimore County requires a permit for fences over 42 inches and for any fence in a 100-year floodplain (at any height); Anne Arundel treats a fence as an accessory structure that needs a permit; Howard County requires one over 6 feet. Front-yard limits commonly sit at 42 inches.
