Accessory Structures in East Providence, RI: What Residents Actually Need to Know

If you live in East 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. East Providence has 4 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

Carport Rules

East Providence regulates carports as accessory structures under Section 19-144 of the Chapter 19 Zoning Ordinance. Section 19-1 limits accessory structures to no greater than 50 percent of the gross floor area of the principal use, and they may not be located between the public right-of-way and the principal building. Setbacks follow Section 19-136, and a building permit is issued under the Rhode Island State Building Code (SBC-1).

Key details: Zoning Section: Sec. 19-144 Accessory Buildings. Setbacks: Sec. 19-136 minimum measurements. Size Cap: 50% of principal gross floor area. Placement: Not between ROW and principal use. Permit Authority: RI State Building Code (SBC-1).

Building a carport without the required East Providence Building Department permit, locating it between the right-of-way and the principal building, or exceeding the 50-percent-of-principal-floor-area limit in Section 19-1 can lead to stop-work orders, code-violation citations, and required removal or after-the-fact permitting. Side-yard or rear-yard violations of Section 19-136 / 19-144 trigger the same enforcement, and applicants who cannot meet the setbacks must apply to the Zoning Board of Review for a dimensional variance.
