Trying to understand lot lines near Little Compton? What you want is the Newport plat map, as it records the lot layout that deeds refer to. In this Newport guide: where to request a copy, plat versus tax map, and the details that matter to buyers.
Who keeps the Newport plat map
Recorded plats sit with the town or city clerk, usually in a plat book or cabinet.
Getting to the right map
Lots and tracts near Portsmouth appear on the RIGIS statewide Tax Parcels layer in ArcGIS Map Viewer, which opens without registering. In and around Middletown, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. Out toward Little Compton, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.

City limits and county records
Newport sits in Newport County, Rhode Island, so its parcels are on the county's map. For property near Tiverton, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the city limits toward Tiverton usually follows county rules rather than the town's.

Which office to call
