Baltimore Fence, Pool Barrier, and Historic Permit Guide

Baltimore fence rules address property-line location, height, written neighbor agreements, pool barriers, historic exterior permits, and grade approval near streets or alleys.

Permit takeaway

Baltimore code requires permits for many construction and alteration activities, and the city fence section controls fence location and height.

Zoning and placement

Fences in historical and architectural preservation districts or on landmark-listed exterior structures need a permit before exterior alteration, construction, removal, or demolition.

Building and trade review

Baltimore fence rules limit many fences to 42 inches, allow dwelling-enclosure fences up to six feet in side or rear yards, and require written agreement for fences on a shared property line.

Call before applying when

Call before building if the fence is on a shared line, in a side or rear yard, near a street or alley, enclosing a pool, on a historic property, or taller than the basic limits.
