Cambridge's Sign Regulations: The Rules That Matter

Every city handles sign regulations a little differently. In Cambridge, Massachusetts, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Political Signs

Cambridge exempts political signs from a sign permit as a temporary noncommercial sign, but caps them at 20 square feet under the Zoning Ordinance. A separate 10-square-foot cap applies to noncommercial signs displayed in any district under Section 7.16.13.

Key details: Political sign size cap: 20 sq ft (Sec. 7.16.12.C). General noncommercial sign cap: 10 sq ft (Sec. 7.16.13). Permit needed under cap: No, exempt as temporary sign. Certification trigger: Signs over 25 sq ft (Sec. 7.19). Max fine: $300 per day, per violation.

The Zoning Ordinance's general enforcement provision, Section 9.16, applies to sign violations: a person who violates any provision of the Ordinance may, upon conviction, be fined up to $300 per offense, with each day of a continuing violation a separate offense, or face non-criminal disposition under G.L. c. 40, § 21D with the same $300-per-day cap, enforced by the Commissioner of Inspectional Services. The Superintendent of Buildings is designated under Section 9.11 as the officer charged with enforcing the Ordinance and can deny related permits under Section 9.12 for noncompliance.

The rules around political signs in Cambridge lean permissive, but that does not mean anything goes.

Holiday Displays

In Residence C-1 districts, Cambridge's Zoning Ordinance bars outdoor floodlighting or decorative lighting outright, but carves out temporary holiday lighting used no longer than four weeks in any calendar year.

Key details: Where it applies: Residence C-1 districts. Holiday lighting duration cap: 4 weeks per calendar year. General floodlighting rule: Prohibited outside listed exceptions. Governing provision: Zoning Ordinance § 7.20. Max fine for violation: $300 per day.

Violations of Section 7.20 fall under the Zoning Ordinance's general enforcement scheme in Article 9.000: the Superintendent of Buildings, designated under Section 9.11 as the enforcing officer, can deny permits tied to a noncompliant installation, and a person who violates any Ordinance provision may be fined up to $300 per offense under Section 9.16(1), with non-criminal disposition available under G.L. c. 40, § 21D at the same $300-per-day cap, with each day of continued violation counted separately.

The Bottom Line

Cambridge's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Cambridge is broadly strict or permissive.
