Prepare, Submit and Close a Waltham Building Permit in the Correct Order
Waltham does not use the same application process as many nearby cities. Most building applications must be delivered in person with every required signature, Fire Prevention review and supporting document already complete.
This guide shows exactly where to start, which department handles each trade, what plans Waltham requests, how to read permit-number prefixes, how to estimate the published building fee and what must be finished before the permit can close.

How to Submit a Waltham Building Application
Download the correct application
Use the residential application for one- and two-family work and the commercial application for commercial work and buildings with three or more dwelling units.
Collect every required signature
The city requires completed signatures when the application is dropped off. The property owner must sign. Contractor, CSL, HIC and design-professional signatures apply as required.
Complete Fire Prevention plan review first
New construction, additions, substantial alterations, tenant fit-outs, solar and other plan-based projects may require Fire Prevention review before Building submission.
Prepare the paper and PDF package
Waltham requests paper plans plus a labeled PDF package or thumb drive for many plan-review projects. Commercial plans must be supplied in paper and PDF form.
Bring the complete package to Room 25
Submit at Government Center, 119 School Street, second floor, Room 25 during office hours.
Keep proof of the accepted application
An accepted application normally begins with an A. An issued building permit normally begins with P.
Complete inspections and final closeout
Schedule required inspections, submit as-built or final-cost documents when applicable and confirm the permit record shows the final approval.
