Rockville, MD Fence Regulations: Fence Requirements (2026)

All fences in Rockville must comply with the zoning requirements in Chapter 25, Article 9 of the city code. A zoning permit is required before any fence construction. Fences must not encroach on public rights-of-way, utility easements, or stormwater management areas. Corner lot fences must maintain adequate sight-line triangles at intersections to ensure safe visibility for vehicles and pedestrians. The fence must be placed entirely within the property owner's lot unless a shared fence agreement exists with the adjoining property owner. In planned development zones, fence installations must conform to the approved PD site plan, which may specify approved materials, colors, and maximum heights that differ from base zoning standards. Properties in Rockville historic districts require Historic District Commission review and approval for fence design, materials, and placement to ensure compatibility with the district's architectural character. Electrically charged fences and barbed wire are prohibited in residential zones. The city publishes a Technical Guide for Exterior Alterations covering fencing standards.
