Local Project Overview
Fence Installation · St. Mary's County, Maryland
Set by local rules
In St. Mary's County, whether a Fence Installation needs a permit is set locally, and the county does not publish a single fixed threshold.
General guides describing Maryland fence rules note wide variation by county, with some jurisdictions requiring a permit for any fence over 42 inches and others exempting fences up to 6 feet, but none of these figures could be confirmed as specific to St. Mary's County. The applicable rule should be confirmed directly with the county's Land Use and Growth Management office. The reliable answer comes from Montgomery County Department of Permitting Services. Zoning setbacks apply either way.

Installing a new fence can improve privacy and property value. However, most counties require a permit if the fence exceeds 6 feet in height or is located in the front yard.

Frequently Asked Questions
What happens if I build a Fence Installation without a permit in St. Mary's County?

Can a homeowner pull their own Fence Installation permit in Maryland?
Yes. Maryland generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Maryland Building Performance Standards.
