Do you need a building permit in Worcester County, Maryland?
Unincorporated Worcester County requires a building permit for building construction, including homes and additions; accessory structures 500 square feet or less and uses of land are excluded, though zoning approval may still apply1. Worcester County uses the 2021 IBC, IRC and IECC with local amendments for building-permit submittals on or after May 29, 202413. A landowner building directly and solely for personal use can bypass Maryland’s home-builder registration-number and Guaranty Fund-fee prerequisites by signing the required affirmation; the exception does not remove Worcester County’s building-permit requirement71. An owner performing a home improvement also qualifies for Maryland’s contractor-license-number exception for that permit14. Inside Berlin, the town reviews building work and requires written building permits or approvals before work begins15. Septic permitting remains with Worcester County Environmental Programs countywide4.
Who is the Worcester County building department, and how do you reach them?
Worcester County Development Review & Permitting handles building construction, site plans and subdivisions; reach the department at (410) 632-1200 or 1 W. Market St. Room 1201, Snow Hill, MD 2186316. A residential building permit needs three sets of construction drawings and three site-plan copies; commercial projects need four sets of architect-sealed drawings17. Under the FY26 fee schedule, one- and two-family building work starts at $50 plus a square-footage/value formula, manufactured and mobile homes carry a $100 flat fee, and building reinspections cost $50 per occurrence18. Development Review & Permitting reviews site-plan information for zoning and code compliance before directing applicants to Environmental Programs17. Occupancy or a change in land use requires a county zoning/occupancy certificate19.
Does Worcester County have zoning?
Worcester County zoning applies to unincorporated land; use the county GIS zoning map and current code to identify the parcel’s district220. Ocean City, Berlin, Pocomoke City and Snow Hill administer their own zoning21222324. Septic permitting stays with Worcester County Environmental Programs countywide4. An ordinary dwelling in unincorporated Worcester County needs at least 500 square feet of livable gross floor area25. Lot area, setbacks and height depend on the district and use; the private-well/private-septic provision sets a 100-foot minimum lot width262728. Agricultural activities and agricultural-purpose-only subdivisions are exempt from Forest Conservation Law, while farm structures other than dwellings are exempt from district height limits except in AP; these are not blanket building-permit or zoning exemptions29.
How do septic permits work in Worcester County?
The Worcester County Department of Environmental Programs reviews, permits and inspects septic systems countywide under delegated Maryland authority45. A qualified private-sector designer must prepare the plans; Environmental Programs must approve them, and the septic permit must be issued before building-permit signoff30. No part of an on-site system may be covered or used until the approving authority or its approved third party has inspected and approved it31. Federal soil data rates 0% of Worcester County soils as free of severe limits for a conventional drain field, so budget for a site evaluation and potentially an engineered system32. Property outside public water and sewer service needs a soil evaluation before construction of a plumbed structure33. Within a sanitary service area, building and occupancy permits depend on the required public facilities reaching the county's specified completion milestones34. Start with Environmental Programs35.
Can you live in an RV or tiny home on your land in Worcester County?
Worcester County allows private, noncommercial seasonal camping in cabins, tents, RVs and manufactured or mobile homes in A-1 and A-2, but prohibits permanent or year-round occupancy under those provisions36. In A-1, each listed unit requires five acres, with no more than five units, a 400-foot minimum lot width and 100-foot front, side and rear setbacks; Department of the Environment approval also applies8. Ask the Zoning Division for A-2’s complete parcel-specific standards937. Maryland adopts IRC Appendix AQ Tiny Houses, but the code framework does not authorize placement or occupancy on a particular Worcester County parcel38. An ordinary dwelling in unincorporated Worcester County still needs 500 square feet of livable gross floor area and a zoning/occupancy certificate before occupancy1019. A qualifying manufactured home in A-1 needs a building permit, water and wastewater compliance, at least 1,000 square feet of floor area and a 20-foot minimum depth39.
Building a home in Worcester County: the steps, in order
- Confirm the parcel's zoning district, allowed use and dimensional standards with the Zoning Division2037.
- If public water and sewer are unavailable, obtain the required soil evaluation from Environmental Programs33.
- Have a qualified private-sector designer submit septic plans; the septic permit must precede building-permit signoff30.
- For a private well, obtain Maryland's required well-construction permit12.
- Submit the building application with three residential drawing sets and three site-plan copies, or four architect-sealed commercial sets17.
- Obtain a floodplain development permit for construction, alterations or additions in a special flood hazard zone4041.
- Schedule county building inspections with 24 to 48 hours' notice and county septic inspection before the system is covered or used42531.
- Do not occupy the building or change the land use until Development Review & Permitting issues the zoning/occupancy certificate19.
What to check before you buy land in Worcester County
Before buying unincorporated Worcester County land, confirm the zoning district and applicable lot, setback and height standards with the Zoning Division2026272837. Check public sanitary-service requirements and flood exposure: sanitary-service-area permits depend on facility completion, while special-flood-hazard-zone construction needs a county permit and Coastal A and V-zone designs need professional certification3440. A driveway within state right-of-way needs an MDOT SHA permit43. County access-spacing rules govern specified development approvals; the commercial interparcel-connector requirement does not establish a universal residential-driveway rule4445. All rentals in unincorporated Worcester County need a rental license; short-term licenses cost $200 per dwelling unit annually and are subject to room tax46. Short-term rentals require two off-street spaces, or three when the dwelling’s building permit was submitted on or after April 17, 2026; events for non-lodgers are prohibited46.
Watch-outs
- Short-term rentals in unincorporated Worcester County may use only one rental contract per overnight period, and bedroom occupancy allowances require at least 50 square feet of unobstructed floor area per occupant when more than one person occupies a bedroom47.
- Camping or sleeping on Worcester County property became a criminal misdemeanor carrying up to 30 days in jail starting in July 2025, though the ban applies to County property, not private land48.
- An accessory apartment is allowed only where the parcel's underlying zoning district permits it, and Environmental Programs must find adequate wastewater capacity49.
