Custom Home Builder in King William County, VA
Across the Pamunkey River from Hanover, and closer to our Henrico office than most people expect. One county, two tax rates and two school divisions — which one you get depends on whether your lot is inside the Town of West Point.
Why King William
Why Build in King William County?
King William County sits between the Pamunkey and Mattaponi rivers, which meet at West Point to form the York. Route 360 crosses into the county at Manquin, and most of what gets built out here goes up on land the owner already has — family acreage, a wooded lot, or a parcel off a county road.
- 01
Closer Than It Looks on a Map
Route 360 runs from Mechanicsville across the Pamunkey into Manquin and Central Garage. Manquin is under forty minutes from our Henrico office, Aylett about forty-five, and the courthouse and West Point just under an hour. Tell us where the lot is and we will give you the real drive.
- 02
$0.615 per $100 Outside West Point
King William's 2026 real estate rate outside the town is $0.615 per $100 of assessed value — $4,305 a year on a $700,000 assessment, against $5,670 in Hanover. Inside the Town of West Point the county levy drops to $0.305, but the town adds its own $0.56, for $0.865 combined.
- 03
Two School Divisions
The Town of West Point runs its own school division. King William County Public Schools serves everywhere else. Which one a lot falls in is set by the town line, so it is one of the first things we confirm for a family.
- 04
215 New Homes Last Year, Up From 129
King William permitted 215 single-family homes in 2025, up from 129 in 2024, at an average reported construction value of $227,667. That figure is the structure alone — no land, no well, no septic, no driveway.
- 05
Chesapeake Bay Act Rules Apply
King William is a Chesapeake Bay Preservation Act locality. Disturbing 2,500 square feet or more — which a house with its well, septic field and driveway will — needs local approval and erosion control, and land along perennial streams and tidal wetlands carries a 100-foot protected buffer. On river and creek lots that buffer shapes where the house can go.
- 06
A Reassessment Is Coming in 2027
The county's next general reassessment is scheduled for 2027. If you are buying land now, budget for its assessed value — and the tax on it — to move.
How We Build Here
Building on Your Own Land in King William
Family acreage, a wooded lot or a parcel you are about to close on — the order matters more than the calendar.
- 01
We Walk the Land Before Anything Is Drawn
Access, slope, tree cover worth keeping, the likely drainfield and, near the rivers and creeks, where the protected buffer runs. Every one of those constrains the floor plan, and all of them are cheaper to find on the parcel than on paper. See [lot walk](/lot-walk).
- 02
Health Department First, Then Design
Outside the Town of West Point most parcels are on a private well and septic. The Virginia Department of Health soil evaluation sets the drainfield’s size and position, and that decides where the house can sit — so we run it before design, not after.
- 03
Bay Act Review and Erosion Control, Planned Up Front
A house site crosses the 2,500-square-foot threshold, so the land-disturbance approval and erosion controls are part of every King William build. We plan them with the site layout and hold them through construction.
- 04
One Contract, Not Four Trades and a Spreadsheet
Site work, utilities, the house and the finishes run as a single contract with one schedule and one point of contact. On a build-on-your-lot project across the river, that is the difference between a builder and a project manager you hired by accident.
Frequently Asked Questions
Building in King William — Common Questions
Do you build in King William County?+
Yes — on your own land anywhere in the county, from Manquin, Central Garage and Aylett out to the courthouse and West Point. Manquin is under forty minutes from our Henrico office.
What is the property tax rate in King William County?+
For 2026, $0.615 per $100 of assessed value outside the Town of West Point — $4,305 a year on a $700,000 assessment. Inside the town, owners pay the county $0.305 and the Town of West Point $0.56, for $0.865 combined.
Which schools serve a King William lot?+
The Town of West Point has its own school division; King William County Public Schools serves the rest of the county. The town line decides which applies.
Do I need a well and septic system?+
Outside the Town of West Point, usually yes. The Virginia Department of Health issues both permits, and the soil evaluation decides the drainfield’s size and placement — which is why we do it before design.
What does the Chesapeake Bay Act mean for my lot?+
Building a house disturbs more than 2,500 square feet, so it needs local land-disturbance approval and erosion controls. Land next to perennial streams and tidal wetlands also carries a 100-foot protected buffer, which on a river or creek lot can decide where the house sits. We map it on the lot walk.
