This is a base-district reading of the ordinance text, transcribed from the source below. It is not a Zoning Verification Letter, not a determination by the jurisdiction, not legal advice, and not a substitute for asking the planning department about a specific parcel. Overlays, recorded plan conditions, rezoning stipulations and parcel geometry are not checked here, and any one of them can change the answer on this page.

Verify locally before you spend money. Call the planning counter, pull the parcel's zoning-map designation and its case history, and confirm the section cited above still reads the way it reads here.
