What Common Permit Statuses Mean
Find Watertown Permit History, Status and Missing Documents
Search the current permit platform
Open Viewpoint and search the property or permit. Watertown says building, electrical, plumbing and gas permit history and current status are available online.
Confirm the property in MapGeo
Compare the address, parcel, zoning and available permit-history links.
Search Planning, Zoning and Code Enforcement records
Search by date, date range, address or information type, then open the Record ID for details and attached documents.
Request records only when online sources are incomplete
Watertown warns that online permit lists may not contain every permit or application and records may be at different approval stages.
Old Permit Not Closed? Ask These Questions
Give the department
- Permit number
- Exact property address
- Original scope of work
- Original contractor name
- Available plans
- Current photographs
Ask the department
- Which inspection is missing?
- Is the permit expired?
- Can it be reactivated?
- Are revised plans required?
- Are trade permits still open?
- What proves final closure?
Demolition Requires More Than the Building Application
Health plan
Provide a plan to control noise, odors, dust, asbestos and rodents or pests.
Asbestos
Watertown requires an affidavit from a certified asbestos inspector stating asbestos was properly removed or was not present.
Rodent control
Prepare the required rodent or pest assessment and mitigation information before demolition.
Utilities and DPW
Confirm utility disconnections, street or trench work and any DPW permit or site-plan requirements.
Permit fee
One–three family: $20 per $1,000, $100 minimum. Other structures: $25 per $1,000, $200 minimum.
Do not start early
Work without the required permit is charged at double the permit fee under the published schedule.
Verify Who Is Legally Responsible for the Work
Licensed trade work
Watertown states that plumbing and gas permits are issued only to Massachusetts licensed plumbers and gas fitters.
- Verify active license
- Match name to permit
- Confirm who books inspections
- Keep insurance documents
Residential contractor checks
Massachusetts Home Improvement Contractor registration and Construction Supervisor Licensing are different credentials.
Use the Current Massachusetts Building Code
