Accessory Structures in Richmond, VA: What Residents Actually Need to Know

If you live in Richmond or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Richmond has 9 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

ADU Rules

Richmond allows accessory dwelling units in most residential zones under recent zoning updates. ADUs can be attached or detached, must meet setback and size limits typically 800 to 1,000 sq ft or 30 percent of main house, and require a building permit. Short-term rental of ADUs requires a separate STR permit.

Key details: Allowed: Most residential zones. Size: 800-1,000 sq ft. Owner Occupancy: Usually required. Permit: Building required. Parking: Relaxed.

Unpermitted ADUs are subject to zoning enforcement, fines up to 500 dollars per day, and may require removal or legalization.

Shed Rules

Sheds up to 256 square feet and under 12 feet in height generally do not require a building permit in Richmond under Virginia USBC exemptions, but must meet zoning setbacks typically 3 to 5 feet from side and rear lot lines. Zoning permits may still be required.

Key details: Exempt: Under 256 sq ft. Setbacks: 3-5 ft typical. Height: Under 12 ft. Electrical: Separate permit.

Unpermitted shed placement violating setbacks can result in fines and a requirement to move or remove the structure. Fines up to 500 dollars.

Carport Rules

Carports in Richmond are accessory structures requiring a building permit and must meet zoning setbacks. Carports count toward lot coverage limits and generally cannot be placed in front yards. Minimum side yard setbacks typically 3 to 5 feet apply depending on zoning district.

Key details: Permit: Building permit required. Setbacks: 3-5 ft typical side/rear. Front Yard: Not allowed. Lot Coverage: Counts toward limit. Historic District: CAR approval required.

Unpermitted carport: stop-work order, double permit fee, civil penalty up to $2,500 under VA Code §36-106. Setback or lot-coverage violation: $200-$500 zoning fine per VA Code §15.2-2209, possible removal. Historic district carport without CAR approval: $1,000 plus removal.

Tiny Homes

Permanent tiny homes on foundations in Richmond must meet the Virginia USBC and zoning rules including minimum dwelling size in some districts. Tiny homes on wheels are treated as RVs and cannot be used as permanent residences on residential lots. Tiny homes as detached ADUs may be allowed under the ADU ordinance.

Key details: On Foundation: USBC Appendix Q eligible. On Wheels: Treated as RV, no dwelling. ADU Path: Available up to ~800 sq ft. Min Size: Zone dependent. Loft Height: 6 ft 8 in allowed.

Unpermitted tiny home occupancy: stop-work order plus double-fee penalty under USBC §115. Civil penalty up to $2,500 per VA Code §36-106. THOW used as dwelling: zoning violation, $200-$500 civil penalty plus removal order.

Garage Conversions

Converting a garage to habitable space in Richmond requires building permits, zoning review, and compliance with Virginia USBC for ceiling height, egress, insulation, and HVAC. Conversions creating a separate dwelling unit must follow ADU rules. Required off-street parking must be replaced if zoning mandates it.

Key details: Permit: Building and zoning required. Ceiling: 7 ft minimum (IRC R305). Egress: 5.7 sq ft window. Parking: May need replacement. Historic District: CAR approval needed.

Unpermitted conversion cited under USBC §115: stop-work order plus double-fee penalty. Civil penalty up to $2,500 under VA Code §36-106. Occupancy without a CO is a Class 1 misdemeanor, up to $2,500 and 12 months jail.

ADU Permits

Richmond is in the middle of a major zoning code rewrite (2024-2025) under the Richmond 300 Master Plan to expand ADU availability. Under the current Richmond Zoning Ordinance, ADUs are permitted in many residential districts subject to lot, size, and setback limits. Permits route through the Department of Planning and Development Review (PDR). Virginia has no statewide ADU preemption — Va. Code §15.2-2280 grants Richmond broad zoning authority. The 2021 Virginia Uniform Statewide Building Code applies.

Key details: Authority: Richmond Code Ch. 30; Va. Code §15.2-2280. Rewrite Underway: Richmond 300 Plan (2024-2025). Building Code: 2021 Virginia USBC. Filing: Richmond Online Permits Portal. Historic Review: CAR (Church Hill, Fan, Jackson Ward).

Unpermitted ADU construction violates Chapter 30 enforcement provisions and is subject to civil penalties up to $1,000 under Va. Code §15.2-2286 and stop-work orders by PDR Building Permits. CAR violations in Old and Historic Districts may require removal at owner expense. Chesapeake Bay Act buffer violations carry substantial Virginia DEQ civil penalties. Floodplain violations void NFIP flood insurance coverage.

ADU Impact Fees

Richmond does not charge general residential impact fees on ADUs because Virginia state law tightly limits municipal impact-fee authority. Costs are limited to PDR Building Permits fees, Richmond Department of Public Utilities (DPU) water and sewer connection fees, and stormwater fees. Cash proffers apply only in connection with rezoning, not as-of-right ADU permits. The Richmond 300 rewrite may add affordable-ADU fee waivers but the existing baseline charges remain.

Key details: General Impact Fees: Not authorized statewide. Cash Proffers: Rezoning only (Va. §15.2-2298). Water/Sewer: Richmond DPU (city-owned). Gas: Richmond Gas Works (municipal). Stormwater: Chesapeake Bay Act applies.

Building without permits to avoid fees: stop-work orders from PDR Building Permits, double permit fees on after-the-fact applications, and possible mandatory exposure of concealed work. Unpaid DPU water, sewer, or stormwater charges block service connection and can become liens under Va. Code §15.2-2118 (utility lien authority). Chesapeake Bay Act stormwater violations can carry substantial Virginia DEQ civil penalties under Va. Code §62.1-44.15:74.

The rules around adu impact fees in Richmond lean permissive, but that does not mean anything goes.

ADU Rental Restrictions

Richmond allows ADUs to be rented long-term to a single household subject to the owner-occupancy of the other unit. Short-term rentals (under 30 days) require a separate STR permit and remittance of the city's transient occupancy tax. The Virginia Residential Landlord and Tenant Act (Va. Code §55.1-1200) governs long-term leases statewide. Va. Code §15.2-2208 preempts municipal rent control.

Key details: Long-Term Allowed: Yes, with owner on-site. STR Permit: Required. TOT Rate: 8% city + 5.3% state (approx.). VRLTA: Va. Code §55.1-1200. Rent Control: Preempted (§15.2-2208).

Operating an unregistered STR: Notice of Violation from PDR, fines up to $1,000 per occurrence under Va. Code §15.2-2286, and listing-removal cooperation requests to Airbnb/Vrbo. Failure to remit transient occupancy tax: Richmond Department of Finance collection action plus state-level liability through Virginia Department of Taxation. VRLTA violations: tenant remedies through Richmond General District Court including damages, injunctive relief, and termination.

ADU Owner Occupancy

Richmond's current Chapter 30 zoning code requires owner-occupancy for properties with an ADU: the property owner must occupy either the principal dwelling or the ADU as their principal residence. The Richmond 300 zoning rewrite (2024-2025) is considering loosening this rule. Virginia has no state preemption of local owner-occupancy rules (unlike California or Oregon), so localities retain authority.

Key details: Current Rule: Owner-occupancy required. Rewrite Status: Considering removal (2024-2025). State Preemption: None (Virginia). Penalty: Up to $1,000 (Va. §15.2-2286). HOA Authority: Va. Code §55.1-1800.

Loss of ADU certificate following Notice of Violation from PDR. Civil penalties up to $1,000 per occurrence under Va. Code §15.2-2286. Continued non-compliance can result in the ADU being declared an illegal dwelling unit, requiring de-conversion. HOA enforcement runs parallel to city enforcement under Va. Code §55.1-1800.

The Bottom Line

Richmond's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Richmond is broadly strict or permissive.

These rules come from Richmond's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
