Building permits, zoning and septic rules in West Greenwich, Rhode Island

The Town of West Greenwich, Rhode Island requires a building permit before construction starts1. The town sets its own zoning through Chapter 400 of its town code2. Septic permits come from the state Department of Environmental Management, not the town3. Kent County has no zoning or building authority of its own4.

Do you need a building permit in West Greenwich, Rhode Island?

Yes. The Town of West Greenwich requires a building permit before construction, and an owner who builds without one must stop work until a permit is properly issued1. A permit obtained after work has started costs double the normal fee, with a minimum of $100 added to the stated fee7. Rhode Island's building code makes the same requirement statewide, with a written application to the local building official before covered work begins; ordinary repairs are exempt8. The statewide code now in force took effect in December 20259. Owners who build their own single-family home are exempt only from contractor registration; they still need the permit and inspections6. A new building cannot be occupied until the building official issues a certificate of use and occupancy10.

Who issues building permits in West Greenwich, and what stays with the state?

West Greenwich's own Building Official handles building permits and well permits for land inside the town5. Kent County does not issue building permits or adopt building codes, because Rhode Island counties have no such authority11. We could not confirm the town's current counter hours or online portal, so call Town Hall and ask for the Building Official before you apply. Septic permits are not a town matter: they come from the state Department of Environmental Management3. Driveways onto a state highway need a state permit12.

Does West Greenwich have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. West Greenwich adopted its zoning under Chapter 400 of the town code, last amended in 20162. The code publishes named districts, including the Exit 7 Special Management District, the Corporate Zoning District and two senior residential districts13. Kent County itself does not zone; each municipality does4. Dimensional rules such as lot size, setbacks and building height vary by district, and we could not confirm the table for any residential district, so ask the Building Official, who also acts as zoning official, for the district of your parcel. Manufactured homes must be allowed as single-family homes on lots zoned for single-family use if they meet the state standard and the district's dimensional rules14. We could not confirm the town's rules for tiny homes, accessory dwellings or living in an RV on private land.

How do septic permits work in West Greenwich?

Septic permits for West Greenwich come from the Rhode Island Department of Environmental Management's onsite wastewater program, which reviews site suitability and system design and inspects installations3. Any dwelling with plumbing fixtures where no public wastewater system is available must have a septic system of a type and design the DEM Director approves15. A town cannot issue a building permit for work that needs septic approval until the DEM approvals are presented and still valid15. Kent County's soil survey rates almost no soil as 'not limited' for a conventional drain field16, so expect a site evaluation and possibly an engineered system. Contact the DEM OWTS program at17.

Can you live in an RV or tiny home on your land in West Greenwich?

We could not confirm whether West Greenwich allows living in an RV or tiny home on private land; the town code has a recreational-vehicles chapter, but we could not confirm its occupancy rules. Statewide, extended stays in recreational vehicles are tied to licensed RV parks and campgrounds, which does not answer the question for your own lot18. Inside West Greenwich, mobile-home parks need a town license, and the land must be properly zoned19. Ask the Building Official and zoning official before you buy land with the plan of living in a camper.

Building a home in West Greenwich: the steps, in order

  1. Ask the Building Official which zoning district your parcel is in and what lot size and setbacks apply13.
  2. Check whether the lot touches a Zone A flood hazard area, which the town regulates separately20.
  3. Get septic approval from RI DEM before the town will issue a building permit15.
  4. Apply in writing for a building permit before any work begins1.
  5. Get a well permit from the Building Official for a new domestic well5.
  6. Schedule the required inspections, then obtain the certificate of use and occupancy10.

What to check before you buy land in West Greenwich

Splitting land is regulated: any subdivision of a West Greenwich parcel goes through the town's land development and subdivision regulations in Chapter 45021. Flood-hazard rules apply in mapped Zone A areas20. Typical property taxes in Kent County run at an effective rate of 1.5%22, and the typical home value is about $449,15523. For rules on land outside West Greenwich, see the Kent County page.

Watch-outs

  • Kent County has no zoning or building authority, so only the town's rules matter for a West Greenwich parcel4.
  • The town sets zoning for its own land2, but we could not confirm its rules on RVs, tiny homes, accessory dwellings or minimum home size; ask the West Greenwich Building Official before you buy.
  • A building permit obtained after construction has started costs double the normal fee7.
