What it takes to build here — permits, zoning, and septic — scouted from Middlesex County’s own official sources.
Middlesex County has no functioning county government; building permits are issued by municipal inspectional services (e.g. City of Cambridge) under the state building code 780 CMR, and are required before any construction, alteration, or demolition.
City of Cambridge Inspectional Services - Building Permits ↗Zoning is administered at the municipal level; the City of Cambridge Zoning Ordinance is enforced by its Inspectional Services Department (Lowell and other Middlesex municipalities likewise have their own zoning).
City of Cambridge Inspectional Services - Zoning ↗Cambridge and Lowell are served by public sewer, so on-site septic is largely N/A; where septic exists it is governed by the statewide Title 5 code (310 CMR 15.000) administered by the local Board of Health under MassDEP.
Mass.gov - Title 5 and Septic Systems ↗Under 780 CMR (Ch. 110.R5) a homeowner of a one- or two-family dwelling is exempt from the construction supervisor license requirement and may pull and supervise their own permit; Cambridge provides a homeowner affidavit for this.
