Building permits, zoning and land rules in Somerset County, Maryland

Somerset County requires building permits for construction governed by the Maryland Building Performance Standards; ask Planning and Zoning whether the specific work needs a building permit^1,2. Somerset County has adopted the International Building Code and International Residential Code framework, including subsequent Maryland-adopted versions and county amendments¹³. The local jurisdiction inspects permitted work and issues appropriate use-and-occupancy certificates; project-specific requirements must be confirmed with the issuing office¹⁴. An owner building directly and solely for personal use qualifies for the home-builder registration exception but must sign an owner affirmation and obtain applicable building permits and other authorizations¹². Owner-performed home improvements have a separate contractor-license exception¹⁵.

Somerset County Department of Technical and Community Services, Planning and Zoning, handles county building, zoning and floodplain questions and publishes building permit, utility inspection and energy-compliance forms². The county publishes a development fee schedule, but individual building permit charges, required attachments and review times could not be confirmed; ask Planning and Zoning before filing². Inside Princess Anne, building permits come from the Town Code Enforcement Officer; Crisfield also issues its own building permits^3,5. Private septic systems and wells remain under Somerset County Health Department Environmental Health review, including inside municipal limits where private systems are applicable^7,16.

Somerset County has an adopted zoning ordinance and county zoning maps; the county rules below concern unincorporated land². Princess Anne and Crisfield have their own zoning, while private septic and well review stays with Somerset County Environmental Health^4,6,7. Minimum lot area and setbacks depend on the district, dwelling type and applicable health, water, sewer and Critical Area requirements; there is no single lot-size figure to use for every rural home^17,18. Accessory dwellings are permitted by right in AR, require a special exception in CO and R-1, and are prohibited in I-1, I-2 and AP¹¹. In AR, the accessory unit must accompany an owner-occupied detached single-family home, be smaller than the main home and occupy no more than 50 percent of its living area¹¹.

Somerset County Health Department Environmental Health conducts perc tests, determines septic designs, issues private septic and well construction permits and inspects both systems⁷. None of Somerset County's mapped soils are rated free of severe limitations for a conventional drain field, so establish septic feasibility before buying¹⁹. Many lot evaluations must occur during the seasonal high-water-table period; contact Environmental Health before arranging a perc test⁷. Somerset County's interim individual sewage and water permit requires discontinuing those systems and connecting to community systems when community service becomes available²⁰. Portable toilets cannot support occupation of a new structure and need approving-authority authorization when used longer than 3 days in a 60-day period²¹. A new well requires a Maryland well construction permit⁹.

In unincorporated Somerset County, RV temporary residence is allowed by right in AR or by special exception in CO and prohibited in the other listed districts^8,11. The allowance requires an active residential building permit, at least 5 acres, no electrical service, annual zoning approval and seasonal removal; occupancy cannot exceed 60 days per year or 14 consecutive days⁸. Campgrounds require a separate special exception in eligible districts and are prohibited in R-1, R-2 and R-3; campground approval does not replace the private-lot RV rules^8,22. A tiny house regulated as a dwelling must meet Maryland residential-code, zoning, utility, septic and site requirements¹⁰. Newly placed manufactured homes in unincorporated Somerset County must be HUD-certified and have at least 720 square feet of dwelling floor area, excluding garages, storage rooms and porches, unless a stricter rule applies²². Homes over 10 years old need a third-party structural and code inspection; homes over 3 years old need electrical certification by a licensed electrician²². Ask Planning and Zoning to confirm the placement category and any special exception, especially for an AR parcel whose acreage requirement could not be confirmed because the ordinance wording is inconsistent^2,22.

1. Ask Somerset County Planning and Zoning to confirm jurisdiction, zoning district, permitted use, setbacks and required applications^2,18.

1. Contact Environmental Health early for the lot evaluation, perc test, septic design and well-permit path^7,9.

1. Check flood status: all development in the 100-year floodplain needs a local permit, and work in the 100-year nontidal floodplain also requires a State Waterway Construction Permit²³.

1. Resolve access; work on a residential driveway within a state right-of-way needs the applicable highway permit²⁴.

1. Submit building materials, fees and any owner-builder affirmation, complete inspections, and obtain the appropriate use-and-occupancy certificate^2,12,14.

Confirm Somerset County jurisdiction, zoning, lot dimensions, setbacks and septic feasibility before closing^2,7,18. Outside incorporated towns, subdivision requires an approved, recorded plat; covered lots cannot be sold or receive a zoning permit before final plat recording and construction or guarantee of required improvements¹⁸. The agricultural subdivision exemption requires each tract to be at least 20 acres, retain its agricultural use, add no residence or new street and undergo zoning review¹⁸. Environmental Health separately lists subdivision plat-review fees of $200 for 1–5 lots and $50 per lot for 6 or more lots²⁵. Preserved open space can restrict buildings to customary agricultural or non-commercial recreation buildings allowed by its conservation easement or deed restriction; confirm current requirements with Planning and Zoning^2,17. Check floodplain and wetlands permits, and obtain the applicable highway permit for residential driveway work within a state right-of-way^23,24.
