Cambridge Excavation Permits & Road Bonds Guide
Cambridge, Massachusetts requires permits and often financial guarantees for excavations and street openings within the public way.

Overview: Permits, Bonds, and Who Regulates Them
The City of Cambridge regulates openings, excavations, and restoration of public ways through municipal ordinances and permitting administered by the Department of Public Works (DPW) and associated inspectional units. Typical requirements include a street opening or excavation permit, site restoration standards, and a performance bond or surety to guarantee proper restoration. For the controlling ordinance text see the city code and DPW permit pages below Cambridge Code of Ordinances[1], and the DPW permit instructions Cambridge Department of Public Works - Permits[2].
When a Permit and Bond Are Required
- Excavation or cutting of any public street or sidewalk within the city.
- Installation or repair of underground utilities that disturb the street structure.
- Temporary lane closures or long-term trenching that affects traffic or pedestrian access.
How Bonds Work
Performance bonds or cash deposits are commonly required to ensure that the contractor completes restoration to the city's standards. The DPW sets bond types and acceptable surety forms; amounts are typically calculated by scope or set as a percentage of estimated restoration cost or per-linear-foot rates. Specific bond amounts and formulas are provided with the permit application or referenced ordinance; see the DPW permit page for the official bond instructions DPW permit forms and bond requirements[3].
