Gloucester County

Because Gloucester County contains no incorporated towns, the county is the sole local permitting authority for every parcel in the county. Permitting is administered through two principal county departments at the Gloucester Court House government complex (6489 Main Street): the Department of Planning and Zoning handles zoning permits, Conditional Use Permits, Special Exceptions, site-plan review, subdivision review, Chesapeake Bay Preservation Act review, and floodplain-development review, and supports the Wetlands Zoning Board for tidal-wetlands permitting; the Building Official's office (within the Building Inspections function) handles building permits, USBC plan review, trade permits, and inspections through Certificate of Occupancy. A typical accessory-dwelling permit bundle in Gloucester involves: (1) pre-application zoning inquiry to determine whether the project qualifies for administrative approval (attached / internal accessory dwelling in a qualifying district) or requires a CUP (detached accessory dwelling, the more common case); (2) the CUP path if applicable (Planning Commission and Board of Supervisors public hearings); (3) zoning permit confirming use compliance and Article 9 supplementary-regulation compliance; (4) Chesapeake Bay Preservation Act review — Gloucester IS a Tidewater locality fully subject to the CBPA — including Resource Protection Area (100-foot buffer from perennial water bodies and tidal wetlands) and Resource Management Area buffer review; (5) Wetlands Zoning Board permit if any tidal wetlands or subaqueous bottom is affected, with parallel Virginia Marine Resources Commission and US Army Corps of Engineers review for waters-of-the-US permits; (6) Virginia Department of Health (VDH) Three Rivers Health District construction permit for well and onsite septic on parcels not served by Hampton Roads Sanitation District (HRSD) sewer or by the county's small public-water service areas in the Gloucester Point / Hayes corridor — most of the county relies on private well and onsite septic; (7) HRSD sewer connection (where available) or county-water connection (where available); (8) building permit with stamped residential plans; (9) electrical, plumbing, and mechanical trade permits filed by Virginia-licensed contractors; (10) floodplain development permit if any portion of the parcel is within the FEMA Special Flood Hazard Area; (11) erosion-and-sediment-control / land-disturbance permit (Tidewater 2,500 sqft threshold under the CBPA); (12) sequenced inspections through Certificate of Occupancy.

Process overview: Accessory-dwelling permitting in Gloucester County follows this typical sequence for a detached accessory dwelling on a rural-residential or single-family-residential parcel: (a) applicant performs a pre-application zoning inquiry with Planning and Zoning at 6489 Main Street (free; resolves district, setbacks, CBPA buffer impact, wetlands exposure, floodplain exposure, and whether the project triggers a CUP); (b) applicant files a Conditional Use Permit application with site plan showing principal dwelling, proposed accessory dwelling, setback measurements to all property lines, CBPA buffer distance, wetlands-permit area if applicable, parking, and septic / well or HRSD-sewer / county-water connection; neighbor-notification list per Va. Code § 15.2-2204; CUP application fee; (c) Zoning Administrator technical review for use eligibility, Article 9 supplementary standards, setback / height / coverage compliance; (d) Planning Commission public hearing (typically 60-90 days after a complete CUP application) with staff report and Planning Commission recommendation to the Board; (e) Board of Supervisors public hearing (typically 30-60 days after the Planning Commission hearing) with Board decision — Board may approve with conditions (commonly owner-occupancy, recorded covenant, no separate metering, family-member-occupancy preference), approve without conditions, or deny; Va. Code § 15.2-2286 imposes a twelve-month statutory action limit from a complete application; (f) on CUP approval the applicant proceeds to Chesapeake Bay Preservation Act review with Planning and Zoning — RPA delineation if the parcel has perennial water-body or tidal-wetland frontage (Ware River, North River, East River, Severn River, York River, Mobjack Bay, Piankatank River, the Guinea Marshes complex, or any of the named tributaries), Water Quality Impact Assessment for any buffer encroachment, and stormwater best-management-practice plan for any new impervious surface; (g) Wetlands Zoning Board permit application if the project touches tidal wetlands or subaqueous bottom — monthly hearing cycle, with parallel Virginia Marine Resources Commission and US Army Corps of Engineers review for the federal waters-of-the-US permits typically required for shoreline or near-shore construction; (h) VDH Three Rivers Health District construction permit for well and onsite septic on parcels not served by HRSD sewer or county water — the well-and-septic permit must be in hand before the building permit is issued; the Three Rivers Health District (covering Gloucester, Mathews, King and Queen, King William, Lancaster, Middlesex, and Northumberland counties from offices in Saluda) administers Virginia's onsite-sewage-system program for the Middle and Northern Necks; (i) HRSD sewer connection (where available — principally Gloucester Point and Hayes service areas) or county-water connection (where available); (j) building permit application with the Building Official; stamped architectural plans, structural detail where applicable, energy-code compliance per USBC; (k) trade permits (electrical, plumbing, mechanical) filed by Virginia-licensed contractors; (l) floodplain development permit if any portion of the parcel is within the mapped 100-year Special Flood Hazard Area — Gloucester has significant SFHA coverage along all of its tidal frontage and inland along Beaverdam Run, Aberdeen Creek, and other tributaries; (m) erosion-and-sediment-control / land-disturbance permit for projects exceeding the Tidewater 2,500 sqft threshold under the CBPA; (n) sequenced construction inspections (footing, foundation, framing, rough-in trades, insulation, final building, final electric, final plumbing, final mechanical); (o) Certificate of Occupancy after all inspections pass, with notification to the Commissioner of the Revenue for supplemental real-estate-improvement assessment under Va. Code § 58.1-3292. Attached or internal accessory dwellings in qualifying districts skip steps (b)-(e) and proceed through administrative zoning approval, but all other steps apply.

Impact fees: Virginia counties have narrow statutory authority to charge development impact fees (Va. Code § 15.2-2317 et seq., with most fee authority limited to roads and requiring specific Board of Supervisors adoption and formula-driven computation). Gloucester County imposes Conditional Use Permit application fees, zoning permit fees, site-plan review fees, building permit fees that scale with construction valuation, separate trade permit fees, and Wetlands Zoning Board permit fees, but does NOT impose a California-style per-square-foot impact-fee schedule on accessory dwellings. The Virginia 2% fee levy under Va. Code § 36-137 applies to applicable transactions. The principal county-side cost drivers on a Gloucester accessory-dwelling project are: (i) the CUP application fee (typically several hundred dollars in 2026 dollars; verify current schedule with Planning and Zoning); (ii) building permit fee scaled by construction valuation (a typical detached accessory dwelling at $120,000-$200,000 valuation incurs roughly $800-$1,800 in building-permit fees at Gloucester's adopted rate); (iii) trade permit fees (electrical, plumbing, mechanical, each modest); (iv) CBPA review fee (modest, included in zoning workflow); (v) Wetlands Zoning Board permit fee if applicable (modest); (vi) VDH Three Rivers Health District well-and-septic evaluation fee (billed separately by VDH, varies with site complexity); (vii) HRSD sewer connection fee for parcels in HRSD service area (capacity charge typically several thousand dollars); (viii) Virginia Marine Resources Commission and Army Corps fees for tidal-wetlands and waters-of-the-US permits (modest federal/state fees but consulting and design cost is typically the larger expense). For non-waterfront parcels avoiding the wetlands path, the governmental fee stack on a straightforward detached accessory dwelling in Gloucester is typically in the $2,500-$5,500 range — meaningfully lower than Arlington County's $3,000-$7,000 range and substantially lower than Fairfax County's $7,000-$15,000+ Special Permit ALU range, reflecting Gloucester's rural-county cost structure. Waterfront parcels with wetlands-impact projects add roughly $3,000-$10,000+ in consulting, engineering, and permitting cost across CBPA WQIA, Wetlands Board, VMRC, and Army Corps reviews.

Gloucester County real estate is assessed under the supervision of the Office of the Commissioner of the Revenue, an elected Constitutional Officer with a four-year term serving as chief tax assessor for the county. The Commissioner administers the annual land book, processes personal-property and business-tangible assessments, processes state income-tax returns, administers tax relief for elderly / disabled / disabled-veteran property owners, administers the Land Use Assessment program (Va. Code § 58.1-3230 et seq.) for qualifying agricultural / forestal / horticultural / open-space land, and assesses all new construction and changes to improvements on real estate. The periodic general reassessment of the entire county land book is contracted to an outside reassessment firm and is conducted on a multi-year cycle — Gloucester's recent practice has been a four-year cycle, with intermediate years showing values held flat or adjusted only for new construction and physical changes. An accessory-dwelling addition is captured through the supplemental real-estate-improvement process under Va. Code § 58.1-3292: the Commissioner of the Revenue receives the building-permit record and Certificate of Occupancy from the Building Official and adds the accessory dwelling's assessed value to the parcel's existing land and improvement base, prorated from the completion date through the end of the tax year. The primary dwelling is NOT re-valued off-cycle. Property taxes are billed by the Treasurer (also an elected Constitutional Officer) on a semi-annual schedule (December 5 first half, June 5 second half, per Va. Code § 58.1-3915.3 for localities billing in two installments). Gloucester's real-estate tax rate is set annually by the Board of Supervisors in the budget cycle; the calendar year 2025 rate was $0.695 per $100 assessed value, materially lower than Northern Virginia rates but applied to a rural-county valuation base.

Assessment policy: Gloucester County operates under Virginia's standard fair-market-value assessment regime (Va. Code Title 58.1, Subtitle III, Chapter 32; Va. Const. Art. X § 2). The general reassessment of the county land book is performed by an outside contracted reassessment firm on a multi-year cycle — Gloucester's recent reassessment effective dates have been on a four-year rotation. An accessory-dwelling addition is captured as a supplemental real-estate improvement under Va. Code § 58.1-3292. On receipt of the building permit and Certificate of Occupancy from the Building Official, the Commissioner of the Revenue's office initiates the supplemental assessment — the accessory dwelling is added at its assessed fair-market value (typically derived using residential cost-approach multipliers consistent with the contracted reassessment methodology), prorated from the completion date through the end of the tax year. The existing principal dwelling is NOT revalued off-cycle. Typical Gloucester County accessory-dwelling assessed-value increments for an 800-1,000 sqft detached unit range from roughly $90,000 to $180,000 in the 2026 market (Middle Peninsula construction costs and rural-county comparables), producing a property-tax increment of roughly $625 to $1,250 per year at the $0.695 per $100 assessed-value 2025 base rate — materially lower in absolute dollars than Arlington's $2,000-$4,100 range, primarily because of Gloucester's much lower median property values and lower tax rate, not because of any ADU-specific exemption. Standard Virginia real-estate tax-relief programs apply per local-option rules: elderly / 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 (Gloucester participates in Land Use Assessment, an important consideration for accessory dwellings on parcels in active agricultural or forestal use — adding an accessory dwelling may carve a building site out of the qualifying acreage and trigger roll-back taxes under Va. Code § 58.1-3237 on the carve-out portion). Virginia has no Prop 13-style acquisition-value freeze and no 2% annual-growth cap; future market appreciation of the parcel (land plus principal dwelling plus accessory dwelling) is captured at each general reassessment.

Gloucester County administers several county- and state-level overlay regimes that materially affect accessory-dwelling siting on its very shoreline-rich Middle Peninsula geography: (1) the Chesapeake Bay Preservation Act (CBPA) Resource Protection Area (RPA) 100-foot buffer and the broader Resource Management Area (RMA), mandated by Va. Code § 62.1-44.15:67 et seq. and 9 VAC 25-830, and administered locally through the Gloucester County Chesapeake Bay Preservation provisions in Chapter 17 of the County Code — Gloucester is one of Virginia's most CBPA-impacted counties given its roughly 220 miles of tidal shoreline along the York River, Mobjack Bay (with the Ware River, North River, East River, and Severn River feeding into it), the Piankatank River, and the Guinea Marshes complex at the peninsula's southeast tip; (2) the Gloucester County Floodplain Management Ordinance covering FEMA Special Flood Hazard Areas (the county participates in the National Flood Insurance Program and maintains the standard Tidewater flood ordinance), with significant SFHA coverage along all tidal frontage and inland along Beaverdam Run, Aberdeen Creek, Timberneck Creek, Cedarbush Creek, and the named creek systems; (3) the Wetlands Zoning Board jurisdiction under Va. Code § 28.2-1300 et seq. — a locally constituted board with parallel and additional jurisdiction over any construction in or near tidal wetlands or subaqueous bottom; (4) the Naval Weapons Station Yorktown and Cheatham Annex Air Installation Compatible Use Zone (AICUZ) — the southern boundary of Gloucester County across the York River from Naval Weapons Station Yorktown produces some airspace and noise effect on southern Gloucester (Gloucester Point area), although the AICUZ contour impact is materially smaller than the well-known NAS Oceana / Langley AFB AICUZ effects further south and east; (5) the Gloucester County Historic District / Historic Preservation provisions covering the Gloucester Court House Historic District (a National Register Historic District around the colonial-era courthouse and Main Street commercial core) and several other locally significant historic resources — the Court House district affects accessory-dwelling siting on a small number of parcels in the immediate Court House area but does not produce countywide HALRB-style review; (6) Virginia Marine Resources Commission (VMRC) and US Army Corps of Engineers parallel federal/state jurisdiction over any project affecting waters of the US or state waters — frequent on Gloucester's heavily-indented shoreline. Coastal Commission jurisdiction does NOT apply (Virginia has no California-style Coastal Commission; CBPA, Wetlands Board, VMRC, and the Virginia Coastal Zone Management Program are the functional analogs). Very High Fire Hazard Severity Zones are NOT a Virginia regulatory category. Seismic retrofit zones do not apply in Virginia.

• Chesapeake Bay Preservation Act Resource Protection Area (RPA) 100-foot buffer and Resource Management Area (RMA) — Accessory-dwelling designs that cantilever over, or place impervious surface within, the 100-foot RPA buffer require an RPA Exception. The RPA Exception process in Gloucester involves a Water Quality Impact Assessment (WQIA) prepared by a qualified consultant, CBPA program staff review, and in more impactful cases Planning Commission review with a public hearing. Adding 45-90 days to the overall accessory-dwelling timeline for an RPA Exception is typical. The very high shoreline-to-acreage ratio of Gloucester (~220 miles of tidal shoreline for a 218-square-mile county, several times the typical Virginia shoreline density) means a substantial share of accessory-dwelling projects involve RPA review; waterfront parcels in Ware Neck, Guinea, Severn, Maryus, Susan, Bena, Achilles, Hayes, Gloucester Point, Petsworth, Cappahosic Beach, Glass, and the named neck-and-creek peninsulas should expect RPA review as a first-order siting constraint. Because Gloucester is classified for CBPA purposes as a 'Rural and Suburban' rather than 'Intensely Developed' locality (in contrast to Arlington's IDA classification), Gloucester's RPA / RMA framework is closer to the standard CBPA model — RPA is a hard 100-foot buffer with limited exceptions and RMA stormwater BMPs apply to new impervious surface throughout the RMA.
• Gloucester County Wetlands Zoning Board — tidal wetlands and subaqueous bottom permitting under Va. Code § 28.2-1300 et seq. — Accessory dwellings on waterfront parcels with planned shoreline-protection or access structures (bulkheads, riprap, living shorelines, piers, docks, boat ramps) require Wetlands Board permits. The Wetlands Board operates on a monthly hearing cycle; complete applications are typically heard 30-60 days after submission, with parallel VMRC and Army Corps review (Nationwide Permit or Individual Permit depending on project scope) running for 60-180 days. Best-practice timing places the Wetlands Board / VMRC / Army Corps applications in parallel with the CUP application so all permits are in hand before building permit application. Living shoreline alternatives are now strongly preferred by the Wetlands Board over hardened bulkheads following Virginia's Living Shorelines Act and VMRC's policy guidance — applicants proposing hardened bulkheads on shorelines where a living shoreline is technically feasible should expect challenging review and may need to demonstrate that conditions preclude a living-shoreline approach. The Joint Permit Application (JPA) is the standard intake document covering Wetlands Board, VMRC, Army Corps, and DEQ Virginia Water Protection Permit reviews; applicants should engage a Virginia-licensed coastal engineer or qualified shoreline consultant familiar with Middle Peninsula JPA practice.
• Gloucester County Floodplain Management Ordinance — FEMA NFIP participant — Accessory dwellings in an SFHA must have lowest floor elevated to or above Base Flood Elevation plus any locally-adopted freeboard, with flood vents on any enclosed area below BFE, structural anchoring to resist hydrodynamic and hydrostatic forces, breakaway walls in V zones (coastal high-hazard zones with wave action), and post-construction Elevation Certificate. The Gloucester County Floodplain Administrator (within Planning and Zoning) confirms BFE and zone designation for each parcel and reviews the design for ordinance compliance. Owners of waterfront parcels in the Hayes / Gloucester Point / Achilles corridor along the York River, in Ware Neck, Severn, Maryus, Susan, Bena, Cobbs Creek, Hartfield, and along the named tidal-creek systems should verify current FIRM status before accessory-dwelling design and engage a structural engineer familiar with V-zone and AE-zone Tidewater residential construction. Flood insurance is federally required for SFHA parcels with federally-backed mortgages. FEMA's Risk Rating 2.0 premium structure (effective 2021-2023 phased rollout) prices premiums on parcel-specific flood depth and structural features rather than the prior zone-based system, materially changing the premium economics for some Gloucester waterfront parcels (some owners saw substantial increases on legacy policies as the new rating phased in).
• Naval Weapons Station Yorktown / Cheatham Annex Air Installation Compatible Use Zone (AICUZ) and Felker Army Airfield airspace influence — Accessory-dwelling siting in Gloucester rarely encounters binding AICUZ or Part 77 constraints in practice because the typical detached accessory dwelling is one story or one-and-a-half stories, well within Part 77 surfaces, and because residential AICUZ noise-attenuation requirements apply only in the higher DNL contours which cover a limited footprint at the south end of the county. Owners of waterfront parcels in the southern Gloucester corridor (Gloucester Point, Hayes, Achilles) should verify AICUZ contour status with Planning and Zoning during pre-application consultation and consult the FAA 7460-1 obstruction-evaluation tool for any project at unusual height. The Naval Weapons Station Yorktown noise environment in Gloucester is dominated by occasional munitions-handling events rather than continuous aircraft operations, and is generally compatible with residential use — a meaningful contrast with the NAS Oceana / NAS Langley environments south and east.
• Gloucester Court House Historic District (National Register) and other Gloucester County historic resources — Accessory dwellings on parcels within the Gloucester Court House Historic District boundary are uncommon (the district is principally commercial and institutional rather than residential), but parcels immediately adjacent to the district or on contributing-structure parcels should consult with Planning and Zoning early about historic-context compatibility. Federal historic-rehabilitation tax credits under 26 USC § 47 and Virginia state historic-rehabilitation tax credits under Va. Code § 58.1-339.2 are available for income-producing rehabilitation of National Register-listed structures — a meaningful consideration if an accessory-dwelling project involves converting a historic accessory structure (e.g., a 19th-century smokehouse or carriage house on a National Register-listed property) into a rentable accessory dwelling, though the federal and state credit programs both require qualified rehabilitation expenditures meeting program standards. Most Gloucester accessory-dwelling projects (on parcels in Hayes, Gloucester Point, Ware Neck, Severn, Petsworth, Abingdon, and other non-Court-House communities) do not encounter historic-district review.
