Fiberglass Pool Installation in Berkeley County, WV
Berkeley County is the fastest-growing part of West Virginia’s Eastern Panhandle, and it’s growing in two directions at once: new commuter subdivisions spreading out from Martinsburg, and long-established rural parcels that predate all of it. Those two kinds of property are governed differently enough — on zoning, on covenants, on what a permit application even requires — that “Berkeley County rules” isn’t really one set of rules. This page covers what actually applies, and where the lines fall.
Mostly unzoned — except two places
Berkeley County’s own government answers this plainly: most of the county has no zoning at all. The exceptions are the Tuscarora and Windewald Districts, which have carried their own zoning ordinances since the early 1970s. Everywhere else, there’s no zoning code setting pool setbacks or lot coverage limits the way there is in, say, Jefferson County next door.
That doesn’t mean unincorporated Berkeley County is unregulated, though. The county adopted a new Comprehensive Plan in February 2025 and a Subdivision & Land Use Ordinance in 2024 (amended January 2025) that governs how new development happens even without a general zoning code behind it. It’s a genuinely different governmental structure from Jefferson County, which has run a comprehensive, countywide zoning ordinance since the late 1980s — if you’re used to Jefferson County’s rules, or you’re comparing the two counties, don’t assume Berkeley works the same way. In practice, that means a pool on unzoned Berkeley County land isn’t tested against a set of zoning-code setback numbers the way a Jefferson County project is — it’s tested against the building permit’s own site-plan requirements and whatever the subdivision ordinance or your specific plat happens to require instead.
Berkeley County is also West Virginia’s fastest-growing county by a wide margin, and that growth is concentrated close to Martinsburg and along the commuter corridors toward Maryland and Virginia. The practical effect for a pool project is that “Berkeley County” increasingly means two different kinds of address: an established rural property that predates the current growth wave, and a newer subdivision lot platted specifically to absorb it — and the rules below split fairly cleanly along that same line.
New subdivisions come with mandatory covenants; older rural land might not
Here’s where the county’s newer Subdivision & Land Use Ordinance actually bites. Every final subdivision plat approved under the current ordinance has to come with a recorded Declaration of Protective Covenants and Restrictions, reviewed by the Planning Commission’s own legal counsel, governing maintenance of shared common areas and open space. In practical terms: a lot inside a subdivision platted under the 2024 ordinance comes with real, recorded, HOA-style covenants as a condition of the subdivision existing at all.
An older rural parcel, platted decades ago or never subdivided in the first place, may have none of that — no covenants, no architectural review board, nothing beyond whatever deed restrictions happen to be on file, which is sometimes nothing. That’s a genuine, practical difference for a pool project: on a newer subdivision lot you should expect an architectural review process before you finalize a pool location or a fence line, and on an older or rural parcel you may not have one at all. Your permit application itself will ask for your subdivision name and lot number, which is as good a first clue as any to which category your property falls into.
What the plat has to show: sinkholes
Berkeley County sits on carbonate bedrock — limestone that the U.S. Geological Survey has documented as producing real karst topography across the county, the same underlying geology that shows up as sinkholes and irregular bedrock depth. The county’s own Subdivision & Land Use Ordinance responds to that directly: every final subdivision plat is required to show remediated and unremediated sinkholes, along with their setbacks, before the plat can be approved.
That’s a useful thing to know even outside the subdivision-approval process itself, because it’s the county’s own planning department formally acknowledging what the ground here can do. If you’re excavating for a one-piece fiberglass shell — which needs a stable, evenly prepared base — it’s worth checking whether your specific lot’s plat notes any sinkhole activity nearby, and treating an honest look at the excavation site as a real early step rather than an assumption.
The permit process — and what changes between an above-ground and an in-ground shell
Berkeley County Building Permits and Inspections handles pool permitting, and the process is genuinely different depending on what you’re installing. An above-ground pool only needs the manufacturer’s installation manual submitted with the application. An in-ground pool needs plans signed and sealed by a West Virginia–registered design professional, including reinforcement and concrete detail and footing/deck cross-sections — and if the pool has a bottom drain, it also needs a licensed pool installer and compliance with ANSI/APSP-7 entrapment-protection standards.
The inspection sequence for an in-ground pool runs through excavation, electrical bonding where applicable, an in-ground panel inspection before the concrete pour, final electrical, and a final inspection. The county’s fee schedule is itemized rather than flat, scaled to the size of the pool and the deck around it. Before the county signs off, you’ll sign a Certificate of Compliance acknowledging that using the pool before the final inspection can get it posted as an unsafe structure, with legal action possible — and permits here void automatically if there’s no inspection activity within 180 days, which is worth keeping in mind if a project stalls partway through. The barrier code is the 2018 International Swimming Pool and Spa Code: a minimum 48-inch barrier, the standard 4-inch sphere rule for openings, and self-latching gates.
The ANSI/APSP-7 entrapment-protection requirement for bottom-drain pools deserves a specific mention, because it’s a real, separate compliance item from the barrier code — it governs the drain and suction-fitting hardware itself, not the fence around the pool, and it’s why a bottom-drain in-ground installation needs a licensed pool installer signed onto the permit rather than a general contractor alone. On a shell-only project, confirming which drain configuration your chosen model uses, and whether it triggers this requirement, is worth doing before the permit application goes in rather than after.
Inside Martinsburg city limits, it’s a different code
If your property is inside the City of Martinsburg rather than unincorporated Berkeley County, the county’s process above doesn’t apply — Martinsburg administers its own building code. The city’s ordinance requires a pool to sit within the same setback lines that apply to the main house’s side and rear yards, though a hard-surface pool patio flush with grade is exempt from that setback if it isn’t raised above the ground. Martinsburg’s code defines a “pool” broadly, as any structure holding water more than 24 inches deep — worth knowing since that threshold is lower than what triggers pool rules in some other jurisdictions. As with the county/incorporated-town split we see in Jefferson County next door, the first real question for a Berkeley County project is which government’s rulebook actually applies to your address.
Well and septic
Outside Martinsburg and the county’s newer public-water-served subdivisions, a lot of Berkeley County still runs on private wells and septic systems, and the county’s own plat standards set real distances: an individual well has to sit at least 100 feet from any septic system and at least 10 feet from any property line, and septic reserve areas and filter-field locations have to be shown on the plat and approved by the state health department. If you’re planning a pool on well-and-septic land, mapping those three things — well, septic system and reserve area, and the pool site — together, before you commit to a location, avoids finding out about a conflict after excavation has started.
Getting a shell onto Berkeley County land
The access question splits along the same line as everything else here. In a newer subdivision, lots tend to be laid out with paved streets and defined lot lines, which usually makes access straightforward but can mean tighter side-yard clearance and, per the covenants above, a design that needs architectural review before it’s finalized. On older rural acreage, access is usually the easier problem — wide open land and long driveways — but the property itself, its access road, and where a delivery truck or crane can actually stage, deserve an honest look before a shell model gets chosen.
Setbacks: zoned districts and subdivision plats
The Planning Department names two zoned districts, Tuscarora Community and Windewald Neighborhood, mapped on the county’s Planning & Zoning Regulations page. Both ordinances list swimming pools on residential lots as a customary accessory use, limited to occupants and guests with no admission or membership fee. Accessory structures count toward lot coverage, and accessory buildings go in the rear yard at least 5 feet from the rear lot line. For anything not listed, the zoning administrator decides.
Outside those districts, the Subdivision & Land Development Ordinance sets residential building setback lines of 20 feet front, 10 feet side and 20 feet rear for the subdivisions it approves (Section 504). For setback purposes it exempts only fences, sidewalks, driveways, curbs, hydrants and mailboxes from “structure,” and the county’s pool permit packet asks for the pool’s distance from property lines and building restriction lines. A lot recorded before setbacks were required may show none.
Floodplain: excavation counts as development
Berkeley County’s floodplain ordinance (posted version dated June 11, 2009) defines development to include filling, grading, paving and excavation. Development in the floodplain needs a permit or certificate of compliance from the Floodplain Administrator, the county’s Planning Director. In a mapped floodway it allows no encroachments, including fill or new construction. The county’s pool packet requires a West Virginia design professional for any structure in the floodplain.
The maps are changing. As of an October 2025 coordination meeting, the effective maps dated from July 2009, and FEMA’s preliminary maps issued August 29, 2025 showed the floodplain widening along Opequon Creek, Dry Run and Evans Run (FEMA coordination meeting notes). Check which maps apply to your parcel before fixing a pool location.
Stormwater: 5,000 square feet and one acre
Two disturbance numbers appear on Berkeley County pages. The Planning Department says a site plan is required for projects disturbing more than 5,000 square feet, with Planning Commission approval before earth-moving. The county Stormwater Ordinance applies at one acre of land disturbance, or where a project creates 5,000 square feet of impervious cover that is 40 percent or more of a parcel or sits in a designated stormwater hotspot. It counts pools, decks and patios as impervious cover, and clearing, grading, excavating and filling as disturbance. The County Engineer may waive an engineered site plan for a single-family residence on one lot with under one acre of disturbance. Ask whether that covers a pool at an existing home.
Limestone soils, rock depth and sinkholes
The USDA Natural Resources Conservation Service’s Soil Survey of Berkeley County maps limestone soils across the Great Valley. Its Hagerstown-Funkstown unit covers 26 percent of the county. Hagerstown silt loam on 3 to 8 percent slopes has bedrock deeper than 60 inches and moderate shrink-swell in the subsoil, with sinkholes in some areas. In the Carbo-Opequon complex, bedrock lies 20 to 40 inches down under Carbo soil and 12 to 20 inches under Opequon soil. Both have high shrink-swell potential, depth changes greatly over short distances, and in most areas the rock has to be blasted to excavate it.
In practice, where rock sits that shallow a pool excavation will meet it, so rock removal and a uniform bed become part of the plan, and swelling clay is a poor neighbor for a rigid shell. The subdivision ordinance (Section 404.5) keeps sinkholes remediated or 50 feet from construction and calls for a professional subsurface investigation of improvements within 100 feet of one. Those are plan-review rules, so ask whether they reach a single-lot pool.
Taking out an old pool in Berkeley County: what the county publishes
Berkeley County’s building permit page says a building permit is required to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure. The county’s swimming pool checklist covers new pools: sealed plans for an in-ground pool, drain and entrapment details, and the required inspections. It does not mention removing, filling or abandoning one. We found no county page on pool removal, so call Building Permits and Inspections at 304-264-1966 to ask whether a removal needs a demolition permit before the work is priced or scheduled.
The same page requires a Floodplain Certificate for construction activity in a mapped 100-year floodplain, and the floodplain section above explains why excavation counts as development here. If the old pool is in or near a mapped floodplain, ask whether taking it out is treated the same way. We also found no county or state page on draining a residential pool, so settle where the water will go with the local sewer or stormwater office before the old pool is emptied. Our guides to partial vs full pool removal and how to verify a pool removal contractor cover the questions to bring, and our pool removal and replacement page explains how Calm Water Pools coordinates removal and replacement.
A sensible order of operations
- Confirm whether your property is inside unincorporated Berkeley County, inside the Tuscarora or Windewald zoned districts, or inside Martinsburg city limits — each has a different rulebook.
- If you’re in a subdivision, check whether it was platted under the current Subdivision & Land Use Ordinance and pull the recorded covenants before you finalize a pool layout.
- Check your plat for any documented sinkhole activity near your lot, and treat a real look at the excavation site as an early step, not an afterthought.
- Confirm whether you’re installing an above-ground or in-ground shell — the permit package and the professional sign-offs required are genuinely different.
- If you’re on well and septic, map the well, the septic system and its reserve area, and the pool location together before you commit to a spot.
- Walk your site’s access — road, driveway, staging area — for a rigid one-piece shell delivery.
- Then submit your permit application, confirm the itemized fee, and build your inspection sequence into the project schedule.
