Do you need a building permit in Westmoreland County, Virginia?

Yes. Westmoreland County requires a building permit before covered principal or accessory buildings, structures, uses, additions and structural alterations proceed; the zoning permit must come first, although both applications may be reviewed together1. The Building Official must approve or deny a complete application within 10 business days, and an issued building permit is valid for 1 year1. The county administers Virginia's statewide building code13. Most qualifying farm buildings or structures are exempt from the building code only when they are nonresidential, on operating farm property and used primarily for qualifying farm purposes; zoning, land-disturbance, stormwater, electrical and other permits may still apply12. An owner-builder exemption can remove contractor-licensing requirements for a qualifying primary residence, but it does not remove building-code compliance or the permit itself11.

Who handles Westmoreland County building permits, and how do you reach the office?

Westmoreland County Building & Zoning handles building permits, inspections, zoning review and land-use applications: call 804-493-0120, email landuse@westmoreland-county.org or write to P.O. Box 1000, Montross, VA 2252014. Applications may be submitted through the county's Citizens' Permit Portal14. Building applications must document the parcel, proposed building locations, utilities and drainage, and a zoning permit is required whenever a building permit is required15. County permit fees follow the Board of Supervisors' schedule, and additional processing charges may apply when a review costs more than the estimated average16. After final approval, land or buildings covered by the ordinance cannot be used or occupied until the Building Official issues an occupancy permit17.

Does Westmoreland County have zoning?

Yes. Westmoreland County administers zoning in unincorporated territory; incorporated towns may apply separate rules, so confirm whether a parcel sits inside town limits18. Building permits and zoning approval for unincorporated land come from the county, while septic and well permits come from the Three Rivers Health District wherever the parcel sits195. The county publishes base districts, overlays, use tables and district regulations4. Standards are parcel-specific: in the Agricultural Conservation district, a standard single-family lot is generally listed at 10 acres outside the 100-year floodplain with 100-foot front and 40-foot side and rear setbacks; the Rural Conservation figures are 5 acres, 50 feet in front and 40 feet at the sides and rear2021. Both districts generally cap building height at 35 feet, subject to stated exceptions22. We could not confirm a countywide minimum dwelling floor area or complete lot-coverage limits, so have Building & Zoning identify the parcel's district and overlays before laying out a house14.

How do septic and well permits work in Westmoreland County?

Outside Westmoreland County's public sewer service areas, a new private septic system requires a septic permit from Three Rivers Health District Environmental Health Services, which first determines whether the soil supports a system3. A septic construction permit is valid for 18 months and does not transfer to a new owner, so a buyer should not rely on the seller's permit23. Call the Westmoreland County Health Department's Environmental Health line at 804-493-1235 or visit 18849 King’s Highway, Montross, VA 2252024. After installation and inspection, the Health Department must issue an operation permit before the local Building Official can issue a certificate of occupancy25. Additions, replacements and redevelopment involving an existing system receive project-specific review, so confirm the required evaluation before changing a house footprint or bedroom count26. Only 12% of mapped county soils rate as free of severe limitations for a conventional drain field, making septic feasibility an important purchase contingency27. A private well also needs a permit: the Health Department inspects it, drinking wells need satisfactory bacteria-free water-sample results, and the fee is $3006.

Can you live in an RV or tiny home in Westmoreland County?

Westmoreland County does not allow an RV or similar equipment to be used for living, sleeping or other occupancy while parked or stored on a residential lot or another location not approved for occupancy7. A permitted travel-trailer park is different, but campers and travel trailers there are limited to 14 consecutive days7. The county materials do not define a tiny home as a distinct occupancy type, so a site-built small house still needs the normal building and zoning approvals89. Virginia's residential code offers an alternative path for dwellings of 400 square feet or less, but that addresses code compliance only and does not grant zoning approval, septic approval or a right to occupy10. Manufactured homes are allowed for single-family residential use in the Agricultural Conservation and A-1 districts when installed on a permanent foundation, stripped of transportation tongue and axles, and made compliant with applicable zoning and building-code standards28. Accessory dwellings are allowed with one unit per qualifying lot and a 1,200-square-foot cap29.

What are the steps to build a home in Westmoreland County?

  1. Ask Building & Zoning to identify the parcel's district, overlays, permitted residential use, lot size and setbacks414.
  2. Confirm public sewer and water availability; otherwise obtain septic and private-well approvals through Three Rivers Environmental Health30331.
  3. Document an existing driveway, private-road access or the required VDOT entrance approval32.
  4. Submit the zoning and building applications with the plans and supporting documents the county checklist requires15.
  5. Pay the invoiced fees under the county schedule33.
  6. Arrange required building inspections as work proceeds34.
  7. Complete the septic inspection and operation permit, pass final building review, and obtain the occupancy permit before moving in2535.

What should you check before buying land in Westmoreland County?

Start with the zoning district and septic feasibility: Westmoreland County uses district-specific lot sizes and setbacks, while only 12% of mapped soils rate as free of severe limitations for a conventional drain field363727. Check flood exposure before choosing a house site because floodplain rules restrict residential development and variances38. Confirm legal access and whether the permit checklist requires VDOT approval, private-road documentation or an existing driveway culvert32. Public water and sewer serve only specified areas, so verify service rather than assuming it reaches the parcel30. Subdividing land requires county plat review and approval39. For carrying costs, the effective property-tax rate is about 0.6%, the median annual bill is about $1,506, and farmland value averages about $5,735 per acre404142.

Watch-outs

  • An installed septic system must pass inspection and receive an operation permit before the local Building Official can issue a certificate of occupancy25.
  • Only 12% of mapped soils rate as free of severe limitations for a conventional drain field; make an approved site evaluation a purchase contingency273.
  • An owner-builder exemption concerns contractor licensing, not the building permit or code; qualifying owners must still follow county review11.
  • Septic construction permits expire after 18 months and do not transfer with a sale, so ask Three Rivers Environmental Health about the status of any permit that comes with a lot23.

Water rights & wells in Westmoreland County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Virginia’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

Household wells are exempt from the groundwater withdrawal permit even inside a Groundwater Management Area, but a private well in a GWMA must be registered with DEQ within 30 days (Va. Code 62.1-258); a permit is triggered only at 300,000 gal/month.

Limit: < 300,000 gal/month (no withdrawal permit)

Virginia DEQ — Ground Water Withdrawal Permitting ↗
  • Eastern Virginia Groundwater Management Areapartial of county

    DEQ has imposed mandatory withdrawal reductions on large Coastal Plain permittees because permitted demand exceeds sustainable aquifer yield (declining heads, land subsidence, saltwater-intrusion risk). Household wells (<300,000 gal/mo) are exempt but must be registered. The I-95-west counties (Fairfax, Chesterfield, Hanover, Henrico, Prince William, Spotsylvania, Stafford, Caroline) are included only east of I-95.
