Accessory Structures in Providence, RI: What Residents Actually Need to Know
If you live in Providence or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Providence has 3 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.
ADU Rental Restrictions
Providence allows one accessory dwelling unit per lot in residential districts, but the zoning ordinance flatly bars renting that ADU out short-term.
Key details: ADUs per lot: one, in residential districts. Short-term rental use: not permitted in ADU. Size cap: 60% of principal GFA. Bedroom cap: two bedrooms max.
Renting an ADU as a short-term rental violates Section 1302.U's use restriction; the property remains subject to zoning enforcement, and an ADU built or leased outside these standards loses its permitted-accessory-use status.
This is not one of those rules that cities tend to ignore. Providence actively enforces its adu rental restrictions requirements.
ADU Rules
Providence allows one accessory dwelling unit per lot in every residential district, capped at 900 square feet for a studio or one-bedroom and 1,200 for a two-bedroom, with short-term rentals barred.
Key details: Units per lot: One ADU per lot. Size cap: 900–1,200 sf depending on bedrooms. Bedroom limit: Two bedrooms maximum. Foundation: Permanent foundation, not mobile. Short-term rentals: Not permitted in ADUs.
Building or renting out an ADU that breaks these size, foundation, or bedroom limits is a zoning violation; the zoning enforcement officer can order corrective action, and Code-wide fines run $1 to $500 per day under § 1-10.
Shed & Carport Rules
Providence caps detached sheds and other accessory structures at 10 feet high at the lot line, requires a 3-foot setback, and bars them from front yards.
Key details: Max height: 10 ft at lot line, up to 20 ft. Min setback: 3 ft from lot line. Front yard: Sheds prohibited. Permit: Required unless exempted.
Building without the required permit or placing a shed in a prohibited yard or setback is a zoning violation subject to Inspection and Standards enforcement, including stop-work orders and removal.
The Bottom Line
Providence'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 Providence is broadly strict or permissive.
This guide is based on Providence's current municipal code. Local rules can and do change, so check the individual ordinance pages for the latest details, penalties, and FAQs.
