Southbridge, Massachusetts Building Permit Guide

In the Town of Southbridge, Inspection Services at Town Hall, 41 Elm Street, issues building permits and the electrical, plumbing and gas permits, taking applications through the Town’s OpenGov portal or on paper forms brought in or mailed. Building fees are $8 per $1,000 for one- and two-family dwellings and $10 per $1,000 for everything else, with a minimum for each type of job, such as $500 for a new single-family home.

What requires a building permit in Southbridge?

The Town’s permitting guide says Inspection Services issues building permits and the permits for demolition, electrical, mechanical and plumbing work, changes of use or occupancy, and signs. Its fee sheet shows how wide that net is.

What Southbridge decides and what the state holds

The building code itself is 780 CMR, the State Building Code issued by the Board of Building Regulations and Standards, which the Town enforces without changes. Southbridge sets its own fees and fines, its Zoning Bylaw (adopted and amended by the Town Council and kept on eCode360), its wetlands protection bylaw and its land-use permits. The permitting guide notes that a single-family home outside historic districts and away from wetlands may need only a building permit and a final inspection.

Southbridge building department: who handles permitting

Inspection Services is run by Building Commissioner Theodore Tetreault, with an administrative assistant, a wiring inspector and a gas and plumbing inspector. Its pages describe the department as working with contractors and homeowners to keep new construction and renovations in line with state and federal rules.

Mailed applications go to Inspection Services at the same address with a check to the Town of Southbridge, copies of the contractor’s licenses and certificate of insurance, and the workers’ compensation affidavit; add a stamped self-addressed envelope if you want the permit card mailed back.

Southbridge permit types and forms

The building page posts separate applications for single-family homes and for commercial and other buildings beyond one- and two-family use, plus a sign permit, a sheet metal permit, the workers’ compensation affidavit, a table of work that needs a home improvement contractor registration or a construction supervisor license, and a homeowner warning notice. The plumbing and gas page has residential and commercial plumbing applications, a gas application and the state commercial plumbing code reference.

Residential permits

The department’s memo on new buildings lists what a new house needs at filing: the residential application, copies of the construction supervisor license and home improvement contractor registration, the certificate of insurance and workers’ compensation affidavit, a preliminary HERS report, three copies of the plans including a plot plan, and the fee. An owner who will live in the new home for at least a year after it is finished signs the homeowner warning notice. A driveway permit application is filed with the Building Department too, after the driveway and property lines are marked on the ground, and water and sewer connection permits go to the DPW at or before the time the building and driveway permits are filed.

Accessory dwelling units

Section 8.10 of the Zoning Bylaw, posted with the May 2025 bylaw updates, allows one accessory dwelling unit by right on a lot wherever single-family homes are allowed; more than one needs a Planning Board special permit. The unit may be no larger than half the floor area of the main house or 900 square feet, whichever is less, must meet the setback and lot rules for a house or an accessory building, whichever are more generous, and needs one off-street space unless it is within half a mile of a transit station. It cannot be rented for less than 31 days without a special permit. Every ADU application includes a site plan for the Building Department, which may send it to the Planning Board for a limited site plan review of tree and grade changes, style, water and sewer or septic service, and parking.

Commercial permits

Anything other than a one- or two-family dwelling is charged at $10 per $1,000, with higher minimums for commercial demolition ($300) and commercial solar ($300). Annual inspections are $200, and multi-family inspections $50 per unit. Permit fees on Town-owned buildings may be waived, but that work is still inspected by the department.

For tenant improvements and new commercial builds, Alliance handles commercial permit filing through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning. The Economic Development and Planning office at Town Hall (508-764-5402) reviews projects and takes a Zoning Request Form through online permitting to say whether a use is allowed. The Zoning Board of Appeals hears special permits, variances, comprehensive permits and appeals of the Building Commissioner’s decisions under Section 902 of the Zoning Bylaws, with abutters notified at least two weeks before a hearing. Its filing fees are $100 for an appeal of the Building Commissioner, $150 for a residential variance, $200 for a non-residential variance and $200 for a special permit to alter or extend a nonconforming use or structure, paid to the Town Clerk before a petition counts as filed; the Planning Board also serves as a special permit granting authority.
• Conservation Commission. Work within 100 feet of a wetland or 200 feet of a perennial stream must be reviewed under the Wetlands Protection Act and the Town’s wetland bylaw, approved in October 2022. Application packages are at the Office of Planning and Development in GAR Hall; the Commission usually meets at 5:30 pm on the first and third Thursdays. Proposed wetland regulations dated October 22, 2026 are posted with a public comment form; they are a draft, not yet adopted.
• Health Department. Septic and Title 5 inspections are done by the Health Department, which takes its forms through OpenGov; the Director of Public Health is at 508-764-4252.
• DPW. Water and sewer connections, the house number and any subdivision requirements must be signed off before the building final.

Southbridge permit costs and fees

The building fee sheet now posted carries an approval signature dated September 1, 2025; the plumbing and gas sheet is dated September 17, 2024 and the wiring sheet October 7, 2024. Building permits are figured at $8 per $1,000 of cost for one- and two-family dwellings and $10 per $1,000 for other buildings, subject to the minimums below.

For example, a new single-family home costing $300,000 to build is charged $2,400 (300 × $8), above the $500 minimum. Permit cards must be picked up within 14 days of approval or a $50 fine applies, and replacing a lost job card is a $100 fine. Changing contractors or otherwise amending a permit brings an extra review fee set by the Building Commissioner. The fee sheet says the office does not issue refunds, while the Inspection Services page says approved refunds are processed within 180 days, so ask before counting on one.

Trade permits and who may pull them

The new-building memo has the licensed electrician, plumber and gas fitter each submit their own permit, and both trade fee sheets require the contractor to arrange each inspection and be on site for it.

• Electrical: each fee includes two inspections, and extra inspections or reinspections are $100. No wiring may be covered until it has been inspected; the inspector is notified in writing or by phone when the rough wiring is ready and again at finish. Major appliances, air conditioners and well pumps are $100 for the first and $50 for each added unit; alarm and low-voltage work is $100.
• Plumbing and gas: $100 plus $8 per fixture, covering two inspections; each added inspection or reinspection is $75.

Work without a permit in any trade draws a fine of $300 for a residential first offense or $500 for a commercial one, plus double the permit fee, with larger amounts for repeat offenses.

How to apply for a Southbridge building permit

Review, corrections and what causes delay

Under 780 CMR 105.3.1 the building official has 30 days from the filing of an application to approve or deny it. In Southbridge, a new house waits on more than the building review: the DPW connection permits, any Conservation filing and the Health Department’s septic or well approval all have to be in place, and the final inspection cannot be booked until gas, plumbing, electrical, health, water, sewer and DPW house-number sign-offs are complete.

Inspections in Southbridge

Call Inspection Services at 508-764-5412 to book inspections. For a new building the memo lists four building inspections:

• Foundation and drains, followed by an as-built plan filed with the Building Department.
• Framing.
• Insulation, followed by the final HERS report.
• Final, attended by the Fire Department, the Building Department, the Assessors’ Office and the DPW for the driveway.

Building reinspections cost $75 each, charged when work is faulty, illegal or not finished. Trade inspections are booked with each inspector, and the contractor must be there. Occupancy cards, like permit cards, must be collected within 14 days of approval.

Building code and local bylaws in Southbridge

Southbridge enforces 780 CMR, 10th edition, with fines for work done without a permit printed on each fee sheet.
