Accessory Structures in Richmond, VA

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 3 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

Tiny Homes

Richmond's zoning code does not let residents place a tiny home in the backyard as an ordinary accessory structure. A tiny home, defined at Richmond City Code § 30-1220 as a structure of 400 square feet or less, is only a lawful use as part of a licensed assemblage of two or more units serving emergency, transitional, or permanent supportive housing, and only in the B-3 or M-1 zoning districts.

Key details: Tiny home size cap: 400 square feet maximum. Building code tie-in: IRC Appendix AQ101 through AQ105. Permitted districts: B-3 and M-1 only. Minimum assemblage: Two or more tiny home units. Transit proximity: Within 2,640 feet of transit stop.

Placing a tiny home as an accessory structure outside the licensed emergency, transitional, or permanent supportive housing framework, or operating a tiny-home assemblage outside the B-3 or M-1 districts, or without the certificate of zoning compliance required by § 30-698.3, is a zoning violation enforceable by the Zoning Administrator in the Department of Planning and Development Review, which reviews and issues the certificate under Article X, Division 3 of the zoning chapter.

This is one of the stricter rules in Richmond's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Shed & Carport Rules

Richmond caps accessory structures like sheds and detached garages at 20 feet in height and limits their combined footprint to no more than the footprint of the main house. Placement within required yards depends on the structure's height and the zoning district, with extra clearance required near alleys and side lot lines.

Key details: Max height: 20 feet. Alley clearance (12-ft structures): 5 feet minimum. Front yard placement: 100+ feet from street. Combined footprint: Cannot exceed main house area. Governing sections: § 30-680.1 to § 30-680.4.

Building an oversized or misplaced accessory structure without complying with these limits is a zoning violation under Section 30-1080, punishable as a misdemeanor with a fine of up to $1,000. If the violation is not corrected by the court-ordered deadline, each following ten-day period of noncompliance is a separate offense, with fines climbing from $100 up to $2,000, plus a $100 administrative fee to cover enforcement costs.

ADU Rules

Richmond permits one accessory dwelling unit per single-family lot, but caps it at one-third of the main house's floor area or 500 square feet, whichever is greater. City Code § 30-402.2(13) routes ADU structures through the accessory-building standards in Article VI, Division 9, and requires access sign-off from both the Department of Public Works and the Department of Fire and Emergency Services before occupancy.

Key details: ADUs permitted per lot: One accessory dwelling unit per single-family lot. Size cap: Greater of one-third main house floor area or 500 sq ft. Governing section: Richmond City Code § 30-402.2(13). Accessory building height limit: 20 feet citywide, Sec. 30-680.4. Access approval required: Public Works and Fire/EMS sign-off on access.

Building or occupying an oversized ADU, or one that skips the Public Works and Fire and Emergency Services access sign-off, violates Sec. 30-402.2(13) and is enforced as a zoning violation under Sec. 30-1080. A first conviction is a misdemeanor punishable by up to a $1,000.00 fine; if the ADU is not brought into compliance, each following ten-day period is a separate offense carrying fines up to $2,000.00, plus a $100.00 administrative enforcement fee.

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.
