Worcester County's Department of Development Review and Permitting, in the Government Center at One West Market Street in Snow Hill, permits construction for the easternmost county in Maryland — the only one bordering the Atlantic, and the only one whose Critical Area programme covers two systems. The Atlantic Coastal Bays Critical Area and the Chesapeake Bay Critical Area both reach the waters and lands under the bays and their tributaries to the head of tide, plus all land and water within 1,000 feet beyond the landward boundary of state or private wetlands.
Inside them, three land use designations govern. Intensely Developed Areas are where residential, commercial, institutional or industrial uses predominate and little natural habitat remains; Limited Development Areas are developed at low or moderate intensity and still contain natural habitat; Resource Conservation Areas are nature-dominated and support agriculture and forestry. Some activities are permitted only in Intensely Developed Areas. On every waterfront property and every property bordering tidal wetlands there is a 100-foot buffer measured from mean high water, the most landward edge of tidal wetlands or the bank of tributary streams, and the county’s guidance is to contact the county’s Department of Environmental Programs (410-632-1220) before any clearing or cutting in the Critical Area — including a dead tree.
This guide covers Worcester County. Its four incorporated municipalities — Ocean City, Berlin, Snow Hill and Pocomoke City — enforce their own zoning, building and permit rules; confirm the town’s position before filing inside one. Ocean Pines is unincorporated and permitted by the county.
Ask before you cut, even a dead tree. The county's own guidance on the Critical Area is that the majority of development activities in the Critical Area need a permit, that there are limits on lot coverage, tree clearing and development activity in general, and that an owner should contact the Department of Environmental Programs before any clearing or cutting occurs — the question it answers specifically is what to do about a dead tree, and the answer is to ask first.

Typically permit required
- Most development activity within the Atlantic Coastal Bays or Chesapeake Bay Critical Area, including tree clearing
- Work within the hundred-foot buffer measured from mean high tide on waterfront and tidal wetland property
- Subdivision and development in the Critical Area, which carries the county's Critical Area review fees
- New buildings, additions and any structural work on an existing building
- Interior alterations that reconfigure space, add plumbing fixtures or extend circuits, under the building or residential code and the Maryland Building Rehabilitation Code
- Decks, accessory structures above the local exemption threshold, retaining walls and swimming pools, including above-ground pools
Often exempt
- Work outside the Critical Area that the adopted codes place below the permit threshold — but the Critical Area maps decide which side of the line a parcel falls
- Painting, wallpapering, interior finishes, cabinets, flooring and trim
- Like-for-like replacement of windows and doors in the same opening
- Small detached accessory structures below the jurisdiction's exemption threshold and fences below its height limit — the zoning rules still apply
- Minor repairs that do not remove or alter structural members
What is actually local, and what is not
The code editions are the state's. Worcester County's layer is the enforcing office and its amendments to the building and residential codes, its fee schedule, its grading ordinance and its stormwater programme under MDE criteria, and the Atlantic Coastal Bays Critical Area, its hundred-foot buffer and the three land use designations that govern inside it.
Maryland enforces one statewide set of codes, the Maryland Building Performance Standards (COMAR 09.12.51), through the county or city permit office, which may amend the building and residential codes for local conditions. Maryland rules
Who handles permitting in Worcester County?
The Department of Development Review and Permitting is the enforcing office for building permits, at the Government Center, Room 1201 (Monday to Friday, 8:00 am to 4:30 pm). A separate Department of Environmental Programs in Room 1306 administers the Critical Area, its maps, permits and review, forest conservation, and plumbing and gas permits and inspections, and the Critical Area Commission for the Chesapeake and Atlantic Coastal Bays approves the county’s mapping. The county’s forest conservation provisions sit in its public local law, with an election available where a property is bisected by the Critical Area line.

In 2025, building permits issued in unincorporated Worcester County authorized 171 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Permit types
Residential permits
A Worcester County house project checks the Critical Area maps for the parcel first, because the designation — Intensely Developed, Limited Development or Resource Conservation — sets the lot coverage and clearing limits before the building code says anything. Inside the buffer, work is tightly constrained; outside the Critical Area entirely, the ordinary permit route applies. A contractor improving a house holds the state home improvement licence and a new-home builder the state registration.
Commercial permits
Commercial and resort development in Worcester County is shaped by the same designations, with some activities permitted only in Intensely Developed Areas, and Critical Area review fees charged on subdivisions on a base-plus-per-lot basis. Where a property is bisected by the Critical Area line and at least half its area lies within the Atlantic Coastal Bays Critical Area, the owner may elect to develop the whole property under that subtitle, in which case the county's forest conservation provisions do not apply.
Prior approvals, plan review and the local clock
In Worcester County the Atlantic Coastal Bays and Chesapeake Bay Critical Areas both reach 1,000 feet inland, the county's forest conservation law applies outside the Critical Area election, and the coastal floodplain governs the barrier island and bay shores. Maryland sets no deadline for deciding a building permit (though since 1 October 2026 the office must decide within 30 days whether a housing application is complete) — Worcester County publishes its own targets, and they are the number to plan against.

Worcester County permit costs and fees
Fees follow the county's schedules, with Critical Area review charged separately on subdivisions and development activity within the mapped areas.
| Item | Fee or rule |
|---|---|
| Building permit | County schedule by project type and scope |
| Critical Area review, major subdivision | A base fee plus a charge per lot |
| Critical Area development | Review charged for development activity within the mapped Critical Area |
| Buffer work | Constrained within 100 feet of mean high water or the tidal wetland edge; contact Environmental Programs before clearing |
| Forest conservation | Applies outside the bisected-property election under the county's public local law |
| Municipal permits | Charged by Ocean City, Berlin, Snow Hill or Pocomoke City where the work is inside a town |
A bisected property gets a choice. Where a property is cut by the Critical Area line and at least 50 percent of its land area falls within the Atlantic Coastal Bays Critical Area, the county lets the owner develop the entire property under the Critical Area subtitle — and where they do, the county's forest conservation requirements do not apply. It is a genuine election, and it is worth modelling both ways before filing.

How to apply for a Worcester County building permit
Zoning certification, grading and sediment control, stormwater, forest conservation and Critical Area review run ahead of the building permit.
The home builder registration number (required by state law for new homes) or, where the office asks for it, the Maryland Home Improvement Commission licence number goes on the application.
The local application with the building, residential and energy code submittals the scope requires, and trade permits alongside.
Reviewers in the local office check the building, residential and energy codes as the jurisdiction amended them; corrections are answered in writing.
Fees follow the jurisdiction's ordinance and are due before issuance.
Footing to final by permit number, then the use and occupancy certificate that closes the permit.
Review, corrections and what actually causes delay
Worcester County reviews the building permit against the Critical Area designation the parcel carries, which is why the maps come before the drawings. What delays a file here is clearing done before the department was asked, a design that assumed the ordinary lot coverage limits inside a Limited Development Area, and work inside a town filed with the county.

Inspections follow the adopted codes' required sequence — footing, foundation, framing, rough trades, insulation and final — and are requested from the local office by permit number. Work that passes final receives a use and occupancy certificate for new buildings and changes of use, or a final approval on the permit for everything else. Worcester County inspects through the department, with Critical Area compliance — lot coverage, buffer, clearing and planting — checked alongside the building work on parcels within the mapped areas.

Inspections are where schedules slip.
Get a free quote →Which Critical Area applies in Worcester County?
Both — the Atlantic Coastal Bays Critical Area and the Chesapeake Bay Critical Area, each reaching the waters and lands under the bays and their tributaries and 1,000 feet beyond the landward wetland boundary.
What is the buffer?
100 feet measured from mean high water, the most landward edge of tidal wetlands or the bank of tributary streams, on all waterfront properties and properties bordering tidal wetlands, within which development is tightly restricted.
What do the land use designations mean?
Intensely Developed Areas are largely built up, Limited Development Areas are low or moderate intensity with natural habitat, and Resource Conservation Areas are nature-dominated; some activities are permitted only in Intensely Developed Areas.
Can I remove a dead tree?
Contact the Department of Environmental Programs ((410) 632-1220) before any clearing or cutting occurs in the Critical Area; the county answers this question specifically and asks to be consulted first.
What if my property straddles the Critical Area line?
Where at least half the land area lies within the Atlantic Coastal Bays Critical Area, the owner may elect to develop the whole property under that subtitle, in which case the county's forest conservation requirements do not apply.
Which code edition applies?
The 2021 editions of the International Building Code, International Residential Code and International Energy Conservation Code with Maryland modifications, effective statewide on May 29, 2023 under the Maryland Building Performance Standards, with local enforcement required from May 29, 2024.
