Town of Kilmarnock, Virginia: building permits, zoning and septic

New-home construction in the Town of Kilmarnock, Virginia requires a building permit under Virginia’s statewide code; Kilmarnock controls zoning within town boundaries.12 The town identifies county-level building-permit issuance, while septic permits for Lancaster County addresses go through the Virginia Department of Health’s Three Rivers Health District.34 Public-sewer connection requirements and restrictions on private wells make utility availability a key question before buying a Kilmarnock lot.56

Do you need a building permit in the Town of Kilmarnock, VA?

A new home in the Town of Kilmarnock requires a building permit before construction begins under Virginia’s Uniform Statewide Building Code.1 The statewide code also covers additions and specified alterations, installations and demolition, with listed exemptions for some minor work.1

An owner-builder exemption concerns contractor licensing, not permission to skip building-code compliance or building permits.8 Virginia limits that exemption to no more than 1 primary residence owned by the builder for the builder’s own use in a 24-month period.8 Ask Kilmarnock Planning and Zoning to route your parcel’s building-permit application before scheduling construction.910

Who handles building permits and zoning applications in the Town of Kilmarnock?

Kilmarnock’s Planning and Zoning Department handles land-use and site-project questions inside town boundaries.29 The town publishes zoning, conditional-use, rezoning, sign-permit and plat-review forms or links; a single-family home, garage or fence is an example of a small-scale project that may receive administrative review.10

Kilmarnock’s business-development page says building permits and land-disturbing permits are issued at county level, and directs business applicants to Lancaster or Northumberland County’s Building Office.3 That page places town zoning approval before the building permit for business projects.3 For a residential project, ask Town Planning and Zoning which county building office serves the address and what zoning documents must accompany the building application.910

Does the Town of Kilmarnock have zoning, lot-size rules and setbacks?

The Town of Kilmarnock controls planning and zoning within its boundaries, so a county zoning answer does not establish what can be built on a town lot.2 Kilmarnock’s minimum lot area is 20,000 square feet in R-1 and 10,000 square feet for single-family lots in R-2.1112 R-3 lots require at least 1 acre.13

A single permitted use in A-1 requires at least 33,000 square feet, and the administrator may require more with health-official recommendation and Town Council approval.14 Corner-lot side-street yards are at least 30 feet in R-1 and R-3, and 25 feet in R-2; these are specific corner-lot rules, not a complete setback schedule.15 Ask Town Planning and Zoning to identify the parcel’s district and review the proposed footprint.9

How do septic permits and sewer connections work in the Town of Kilmarnock?

For Kilmarnock addresses in Lancaster County, septic permitting remains with the Virginia Department of Health through Three Rivers Health District and the Lancaster County Health Department.4 Virginia requires written authorization before constructing, expanding or modifying a sewage-disposal system.16

Kilmarnock’s comprehensive plan describes a public-sewer connection requirement for human-occupancy development within 250 feet, subject to minor exceptions, and discourages private septic systems.5 Confirm the connection requirement for the parcel with the town before commissioning a septic design.5 Existing private septic systems in Kilmarnock must be pumped out at least every 5 years.7 Lancaster County septic construction permits are valid for 18 months and do not transfer with ownership; after installation and inspection, a health-department operation permit is needed for a certificate of occupancy.17

Can you live in an RV or tiny home in the Town of Kilmarnock?

We could not confirm a Kilmarnock rule authorizing residential RV occupancy or a separate tiny-home use; ask Town Planning and Zoning about the proposed dwelling and the parcel’s zoning district.29 Virginia’s campground rules govern campground operations and do not establish town zoning permission to live in an RV on a private lot.182

A small permanent home still faces Kilmarnock’s district-specific lot rules and Virginia’s building code.111219 We could not confirm a town-wide minimum dwelling size or current accessory-dwelling permission; request a use determination from Town Planning and Zoning before buying a tiny home or converting an accessory building.92

Building a home in the Town of Kilmarnock: what steps come first?

Start with the parcel’s town zoning and utility constraints, then obtain the building authorization required before covered work begins.2520

  1. Ask Kilmarnock Planning and Zoning to identify the district and review the proposed use, lot area and building placement.92
  2. Confirm public water and sewer availability; the town comprehensive plan describes private wells as prohibited except in unusual circumstances approved by Town Council.65
  3. If septic is appropriate, contact Lancaster County Environmental Health for the construction-permit process.421
  4. Have the town identify the county building office for the address, then apply to the building official before construction.320
  5. Complete required inspections and obtain the applicable certificate of occupancy before moving into the new home.2223

What should you check before buying land in the Town of Kilmarnock?

Kilmarnock’s private-well restriction and public-sewer policy can determine whether an intended off-grid plan works, even where a lot meets the zoning minimum.65 In A-1, land using individual sewage disposal requires health-official approval of the area, and a larger lot may be required.14

An entrance connecting to a VDOT-maintained highway requires the applicable VDOT land-use permit; the statewide rule also covers qualifying changes to an existing entrance.24 In special flood hazard areas, the building official may require a building permit even for work otherwise exempt.25 For land outside Kilmarnock’s boundaries, use the Lancaster County guide for the county’s building and zoning answers; town planning jurisdiction stops at the town boundary.2

Watch-outs

  • We could not confirm residential RV occupancy, tiny-home use or a town-wide minimum dwelling size in Kilmarnock; ask Town Planning and Zoning before committing to the dwelling.92
  • A Lancaster County septic construction permit does not transfer to a new property owner, so an existing permit is not enough to assume a purchase is ready for septic construction.17
  • Kilmarnock’s comprehensive plan describes private wells as prohibited except in unusual circumstances approved by Town Council; confirm the current exception process with the town.6
