Full Breakdown

Under RIGL Chapter 23-27.3 (State Building Code), Rhode Island adopts a single statewide building code, including SBC-1 with floodplain provisions tied to the NFIP and ASCE 24. The Rhode Island State Building Commissioner promulgates the code, and municipal building officials enforce it locally. Flood-resistant construction, freeboard, and elevation requirements apply uniformly across all communities. Coastal flood zones are also regulated by CRMC under RIGL 46-23. Local floodplain ordinances must meet or exceed NFIP and state code minimums.

Violations & Penalties

Non-compliant construction in flood zones can result in denial of certificate of occupancy, NFIP insurance penalties, and orders to elevate or remove structures.

Frequently Asked Questions

Can my Rhode Island town set lower flood elevation requirements?
No. Local floodplain rules must meet or exceed the State Building Code and NFIP minimums; weaker requirements are preempted under RIGL 23-27.3 and risk loss of NFIP eligibility.
Who issues my flood-zone building permit?
The local building official issues the permit, but applies the statewide SBC-1 floodplain provisions and confirms compliance with FEMA flood maps and any required CRMC Assent.
