County ADU details
County ADU ordinance
Lee County does NOT maintain a standalone accessory-dwelling-unit ordinance with codified ADU-specific size caps, owner-occupancy provisions, or by-right paths. ADUs are regulated through the 2014 Zoning Ordinance's general treatment of 'accessory use,' 'accessory structure,' and the per-district use schedules. In the Agricultural and Rural Residential districts that cover the great majority of county acreage, one principal dwelling per lot is permitted by right with customary accessory structures; a second independent dwelling unit with full kitchen facilities typically requires a Conditional Use Permit (CUP) from the Board of Supervisors after Planning Commission recommendation. A 'family-member' or 'tenant dwelling / farm labor dwelling' allowance is generally recognized in the agricultural district subject to minimum lot area. A no-kitchen 'guest house' accessory structure is generally permitted as a by-right accessory structure subject to district setbacks, height, and lot-coverage. Manufactured / mobile homes are an additional path in some districts, subject to specific manufactured-home siting standards. Confirm current ordinance text with the Zoning Department at 276-346-7766 before committing to a project pro forma — the ordinance is updated periodically and administrative interpretation is load-bearing.
County permitting (unincorporated parcels)
Lee County's Department of Community Development is a one-stop department combining planning, zoning, building, and code-enforcement functions. A typical ADU-like permit bundle includes: (1) pre-application zoning inquiry to determine whether the project qualifies for a by-right accessory-structure path or requires a Conditional Use Permit, (2) zoning permit confirming use compliance and per-district performance standards, (3) building permit with stamped residential plans, (4) electrical, plumbing, and mechanical trade permits, (5) Virginia Department of Health (VDH) Lenowisco Health District construction permit for well and onsite septic for parcels not served by Lee County Public Service Authority (LCPSA) public water and (where applicable) sewer, (6) floodplain development permit if any portion of the parcel is within the FEMA Special Flood Hazard Area along the Powell River, North Fork Powell, or their tributaries, and (7) erosion-and-sediment-control / land-disturbance permit. For parcels with a coal-mining or coal-bed-methane history, additional title and surface-rights review is recommended; severed mineral rights are common in the Central Appalachian coalfield and can affect surface use, structure siting, and subsidence risk.
County assessor
Lee County real estate is assessed under the supervision of the Office of the Commissioner of the Revenue, with periodic general reassessments contracted to an outside assessment firm hired by the Board of Supervisors (the Commissioner of the Revenue does not perform the general reassessment in-house). The Commissioner administers the land book annually, processes personal property and business tangible assessments, processes state income-tax returns, and (distinctively for Lee) administers a Severance Tax on coal under the county Severance Ordinance: 1.5% on monthly gross receipts under 10,000 tons and 2% on monthly gross receipts of 10,000 tons or more. Mineral interest reporting flows through the Commissioner's office. An ADU or second-dwelling addition is captured through the supplemental real-estate-improvement process under Va. Code § 58.1-3292.
Assessment policy: An ADU is captured as a real-estate improvement under Va. Code Title 58.1 Subtitle III Chapter 32. On receipt of the building permit and Certificate of Occupancy from Community Development, the Commissioner of the Revenue's office initiates the supplemental assessment under Va. Code § 58.1-3292, prorated from the completion date through the end of the tax year. The ADU is added at its assessed fair-market value (typically derived by the contracted reassessment firm using cost-approach residential cost multipliers) on top of the parcel's existing land and improvement value; the existing primary dwelling is NOT revalued off-cycle. There is no Lee-County-specific ADU assessment exemption. Standard Virginia real-estate tax-relief programs (elderly and disabled relief under Va. Code § 58.1-3210 as adopted locally, disabled-veteran exemption under Va. Code § 58.1-3219.5, Land Use Assessment under Va. Code § 58.1-3230 et seq. for qualifying agricultural / forestal / horticultural / open-space land) apply per local-option rules. For parcels with severed mineral rights, the surface owner's real-estate tax base does not include the mineral interest, which is separately assessed.
County overlays (4)
Lee County administers a Floodplain Overlay tied to FEMA Special Flood Hazard Areas along the Powell River, North Fork Powell, Wallen Creek, Indian Creek, and other tributaries. The county is NOT a Tidewater locality and is therefore NOT subject to the Chesapeake Bay Preservation Act — Lee's drainages flow to the Tennessee River system via the Powell River, not the Chesapeake Bay. The county includes Cumberland Gap National Historical Park federal land at the tri-state corner, which is outside county zoning jurisdiction. Karst geology is significant in portions of the county (Powell Valley limestone), with associated sinkhole, cave, and groundwater-protection considerations. A long history of underground coal mining underlies surface parcels in the central and northern county, with associated subsidence risk and severed-mineral title issues. Locally adopted Agricultural and Forestal Districts (Va. Code § 15.2-4300 et seq.) preserve farmland on a renewable petition basis. Lee County has NO designated coastal-commission analog (none exists in Virginia), NO statewide WUI regulatory overlay, and NO seismic-retrofit overlay. There are no FAA Part 150 commercial-airport noise zones reaching the county.
Known county issues (6)
- other — ADU pro formas that would pencil as by-right or ministerial projects in jurisdictions with codified ADU ordinances require a discretionary CUP cycle in Lee County. Budget 90-180 days for the CUP cycle plus ordinary building-permit timeline. Manufactured-home siting on a qualifying parcel can materially reduce total cost relative to site-built ADUs in this rural Appalachian context.
- other — ADU title due diligence in Lee County must include severed-mineral-rights review and Virginia Energy abandoned-mine-land mapping check. Title insurance should be reviewed for surface-rights and subsidence carve-outs. Foundation specification for an ADU above old mine works may be precluded entirely or require enhanced engineering. Plan for this at the title-search stage, not after architectural design.
- other — ADU pro formas on karst parcels should budget for AOSS septic design and pre-construction geotechnical evaluation. Sinkhole-adjacent siting can require setback increases and enhanced foundation engineering. Initiate VDH application in parallel with — not after — county pre-application inquiry.
- other — ADU applicants in Jonesville, Pennington Gap, or St. Charles work through the county Department of Community Development for building permits. Town-level zoning may overlay county zoning in the incorporated areas; verify with both the town clerk and the county Zoning Department before architectural design.
- staffing-shortage — Plan-review and CUP-processing timelines in Lee County can run longer than comparable projects in more-staffed counties. Schedule a pre-application meeting early. Direct contact with the Department (276-346-7766) is often faster than email queue.
- policy-review — Applicants should confirm the current ordinance text with the Zoning Department rather than relying on prior summaries, and should be alert to General Assembly session outcomes in any year when an ADU preemption bill is introduced. A pre-application zoning inquiry is strongly recommended before architectural or engineering investment.
Virginia state — ADU law and programs
State ADU law
Virginia has NOT enacted a statewide ADU preemption law. Virginia is a Dillon Rule state — localities possess only those powers expressly granted by the General Assembly — and the statutes granting zoning authority (Va. Code § 15.2-2280 et seq.) leave ADU regulation to local ordinances. ADU permission, setbacks, parking, size, and owner-occupancy rules therefore vary by county, independent city, and town. Virginia is unique in that it has 38 independent cities that function as counties (neither in nor subordinate to the surrounding county), meaning 'the county' for any given Virginia property may be an independent city rather than a true county. Several ADU preemption bills have been introduced in recent General Assembly sessions (2022 through 2025) without enactment; none have advanced past committee as of the Assembly's 2026 regular session adjournment.
State financing programs
Virginia does not operate an ADU-specific statewide loan, grant, or forgivable-loan program. Virginia Housing (formerly the Virginia Housing Development Authority, VHDA — rebranded 2020) administers general first-time-homebuyer, down-payment-assistance (DPA), mortgage-credit-certificate, and rehabilitation products that can be applied to ADU-adjacent purchases or improvements when eligibility criteria are met, but none target ADU construction as a distinct product. The Virginia Department of Housing and Community Development (DHCD) administers federal HOME and CDBG pass-through funds that local jurisdictions can direct toward ADU-adjacent rehab, but there is no state-level ADU-dedicated line item. Federally available products (FHA 203(k), Fannie Mae HomeReady and HomeStyle Renovation, Freddie Mac CHOICERenovation) remain the primary ADU financing path for Virginia homeowners.
State housing programs
Virginia does not run a state-level pre-approved-ADU-plan catalog, statewide impact-fee-waiver statute for ADUs, or streamlined-review mandate. State-level programs that touch ADU-adjacent policy are coordinated primarily through the Department of Housing and Community Development (DHCD) and Virginia Housing, and act by funding or assisting local jurisdictions rather than by preemption. Local ADU activity — Arlington County's Accessory Dwellings program (detached ADUs permitted since 2008, liberalized 2020), Alexandria's accessory-dwelling ordinance, Fairfax County's accessory-living-unit program, and Charlottesville's 2021 zoning-code changes — is authorized under the localities' Va. Code § 15.2-2280 zoning authority, not by state mandate.
- DHCD Community Development Block Grant (CDBG) Program — Federal CDBG funds administered by DHCD to eligible non-entitlement Virginia localities for community-revitalization, housing-rehab, and infrastructure projects. Not ADU-specific. Participating localities can direct CDBG funds toward housing-rehab projects where local policy supports ADUs.
- DHCD HOME Investment Partnerships Program — Federal HOME funds administered by DHCD to Virginia participating jurisdictions and non-profits for affordable-housing acquisition, rehab, and new construction. Not ADU-specific; can be directed to ADU-adjacent rehab at local discretion.
- Virginia Housing Commission — Permanent advisory commission of the General Assembly that studies housing-policy questions and recommends legislation. Has periodically studied ADU preemption and missing-middle housing without recommending statewide enactment as of 2026-04-21.
- Local ADU ordinances under Va. Code § 15.2-2280 authority — Not a state program — listed here because Virginia ADU policy is executed entirely at the locality level under the § 15.2-2280 zoning grant. A homeowner seeking to build an ADU consults the zoning ordinance of the specific county, city, or town where the parcel is located.
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
