Buying Land in Louisa County, Virginia

Rural Central Virginia, anchored by Lake Anna

Louisa County sits in Central Virginia roughly equidistant between Richmond and Charlottesville, a genuinely rural county of country roads, rivers, farmland, and rolling hills. Its best-known feature is Lake Anna, Virginia's third-largest lake, created when Virginia Electric and Power Company (now Dominion Energy) purchased approximately 18,000 acres in the late 1960s to build the North Anna Nuclear Power Station and its cooling reservoir -- the lake now has over 200 miles of shoreline and draws significant regional recreation and second-home demand. This page keeps its focus on the county's inland agricultural zoning rather than lakefront real estate, which functions as its own distinct market within the county.

North Anna Power Station has also made Louisa a real data-center market

The same North Anna Power Station that impounds Lake Anna also generates roughly 15% of Virginia's electricity and more than 40% of the state's carbon-free power, with high-voltage transmission already built out toward Northern Virginia's data center corridor. That combination has made Louisa a genuinely active data-center growth market: the county created a Technology Overlay District (TOD) in 2023 to steer that development toward suitable parcels, then tightened it in August 2024 to require a conditional use permit -- a public-hearing process -- rather than by-right approval. Two AWS data center campuses are under construction inside the TOD today, a third AWS campus was withdrawn in July 2025 after resident opposition, and AWS separately purchased roughly 1,920 more acres in January 2026, while EdgeCore Digital Infrastructure has announced its own roughly 1.1-gigawatt campus in the county.

For a land buyer, that means a parcel's location inside or outside the TOD -- and whether any pending conditional-use-permit application affects land nearby -- is a real, live factor to check directly with the county, not a theoretical one. See our standalone Louisa County zoning page for the full detail on how the TOD and its conditional-use-permit requirement work, and where the fight over its boundaries currently stands.

Agricultural zoning: A-1 for farming, A-2 for a residential-agricultural mix

Louisa County's zoning ordinance (Chapter 86 of the county code) sets out two agricultural districts, both situated within a Growth Area Overlay District framework. The A-1 Agricultural district is intended to accommodate farming, forestry, livestock maintenance, and other related farm activities -- a district oriented primarily around active agricultural production. The A-2 Agricultural district, by contrast, is described as intended to allow a compatible mixture of agricultural uses and limited residential development in rural areas while protecting and retaining the rural, open character of the countryside -- a somewhat more residential-friendly designation than A-1, though still grounded in preserving rural character rather than enabling suburban-style subdivision.

Each district's specific permitted-use list, minimum lot size, and any special-use-permit requirements are set out in Division 6 of the zoning code, and are worth confirming directly with the county's Planning & Zoning Division for a specific parcel and intended use -- particularly since the A-1/A-2 distinction turns on active-farming versus mixed-residential intent, which can matter a great deal if your plan involves anything beyond straightforward agricultural use.

Septic and well: confirm the health district directly

As with the rest of Virginia, septic and well permitting in Louisa County runs through the Virginia Department of Health rather than a county department. The Louisa County Health Department itself is confirmed at 101 Woolfolk Avenue, Suite 203, Louisa, VA 23093, reachable at 540-967-3707 or LouisaEH@vdh.virginia.gov. What this page could not resolve cleanly is which specific VDH regional health district that office falls under -- different search-indexed sources referenced both the Blue Ridge Health District and the Piedmont Health District in connection with Louisa County, an inconsistency this page is not resolving by guessing, consistent with this project's no-fabrication standard.

For practical purposes, this makes little difference to a buyer: call the Louisa County Health Department's own number directly for septic and well permitting questions rather than trying to route through a district office first, and confirm the current regional district assignment with VDH if that detail specifically matters to your research.
