Sign Types and Where Rules Apply

Cambridge regulates signs by zoning district, sign type, and whether a property is in one of the citys historic districts. Typical categories include temporary signs, permanent wall or projecting signs, awning signs, and A-frame or portable signs. Historic districts may require additional review by the Cambridge Historical Commission.

Enforcement is handled by city departments including the Inspectional Services Department for building and permit compliance and the Cambridge Historical Commission for design review in historic districts. Specific fine amounts for sign violations are not specified on the cited pages; when numeric penalties appear in enforcement notices they will be listed on the department pages or in the municipal code.

  • Fines: amounts not specified on the cited page; check the municipal code or Inspectional Services for current figures.
  • Escalation: first or repeat offence procedures and per-day continuing penalties are not specified on the cited page.
  • Non-monetary sanctions: removal orders, stop-work notices, orders to abate, and court actions are used for noncompliant signs.
