Worcester building department

Worcester’s Building and Zoning Division, part of the Department of Inspectional Services, issues permits for new construction, repairs, additions, alterations, demolition, and changes of use anywhere in the City of Worcester. The same office issues plumbing, gas, electrical, and sheet metal permits and performs all of their inspections. It also interprets and enforces the city’s zoning ordinance and runs periodic safety inspections of schools, restaurants, theaters, churches, rooming houses, hotels, and multifamily buildings.

Staff answer questions Monday through Friday, 8 a.m. to 4:30 p.m. Inspectors are generally in the office from 8 to 9 a.m. and from 3:30 to 4:30 p.m. They are in the field doing inspections from 9 a.m. to 3:30 p.m., so call during those office windows if you need to reach one.

What needs a permit (and what doesn’t)

The division’s FAQ sets these thresholds:

Project	Building permit needed?
Shed	Only if over 200 sq ft
Fence	Not if 7 feet or less. Fences over 6 feet may need zoning relief.
Retaining wall	Not if under 4 feet, measured from the bottom of the footing to the top of the wall
Temporary tent	Only if 400 sq ft or larger

A dilapidated landscape retaining wall up to 6 feet or fence up to 7 feet along a private property line is a civil matter between neighbors. The division doesn’t enforce those disputes.

When you apply online, you pick a building permit classification. The city asks applicants to choose carefully because the wrong one slows review. The classifications are:

• Accessory dwelling unit (ADU), attached, internal, or detached
• Accessory structure (garages, sheds, carports)
• Addition, alteration/renovation, new construction, change of use, and demolition
• Moving a building
• Repair/replace, with subcategories for chimneys, decks, fencing, insulation, roofing, siding, weatherization, and windows
• Restoration after fire, water, or storm damage
• Retaining walls, signs and billboards, solar PV, wood/pellet/coal stoves, temporary tents, and wireless antennas

Applying through OpenGov

Worcester takes applications through its OpenGov Permit/License Center. You need an account to apply, and you can pay by major credit card or ACH. Permit types in the portal include building, certificate of inspection, certificate of occupancy, electrical, gas, mechanical, plumbing, welding card, and zoning analysis. Since January 1, 2022, a $50 administrative fee applies to any permit or license application filed over the counter or by mail. Online filing has no processing fee.

An application is not permission to start. Work may begin only after the application is approved, the fee is paid, and the permit is issued. Your tradesperson license and proof of workers’ compensation insurance must be on file with the department or attached to the application. Depending on the job, you may also need permits from the Fire Department, Police Department, or Public Works. Approvals may also be needed from the Conservation Commission, Historical Commission, Planning Board, or Zoning Board of Appeals.

For larger projects, the city offers free pre-development consultations with its Interdepartmental Review Team. These cover permitting, zoning compliance, engineering standards, and land use.

Homeowner exemption

The division states that owner-occupants of one- and two-family dwellings doing work that needs a building permit are exempt from the construction supervisor licensing rules in 780 CMR 110.R5. If the homeowner hires anyone to do the work, the homeowner must act as supervisor. The exemption does not apply to field erection of manufactured buildings under 780 CMR 110.R3.

Fee highlights

These come from the Department of Inspectional Services Schedule of Fees, effective March 1, 2024.

Item	Fee
Building permit (most types)	$12 per $1,000 of construction value ($9 per $1,000 over $1 million); $100 minimum
Demolition	$5 per $1,000; $100 minimum
Certificate of use and occupancy	$100
Change of use (no construction) or zoning determination	$100
Wood, pellet, or coal stove	$100
Sign	$135
Residential mechanical (up to 3 units)	$100 first fixture, $15 each additional
Residential plumbing or gas (up to 3 units)	$100 first fixture, $15 each additional
Residential electrical: addition/renovation, single-family detached	$100 ($170 with service upgrade)
Residential solar wiring / generator wiring	$250 / $150
Re-inspection	$100
After-hours inspection	$250

Working without the required permit or license costs triple the original permit fee. The minimum penalty is $500 for residential property and $1,000 for commercial property.

Rental registration and periodic inspections

All rented or leased property must be registered every year. The fee is $15 per unit for a first registration and $5 per unit to renew. Rental unit inspections are $50 per unit. The first re-inspection after a failure is free, and each one after that is $100.

Under the state building code’s periodic-inspection table (780 CMR Table 110), the division inspects buildings with three or more units every five years. The city says over 6,500 properties are covered. The inspection covers common areas, and the owner or an agent must be present. The fee for a multifamily certificate is $190 plus $5 per unit, or a flat $200 for a three-family. Restaurants, schools, day cares, hotels, and theaters are inspected every year. Certificates of inspection are issued through the city’s online portal.

Permit history

The city’s Permit History search covers building, electrical, gas, mechanical, plumbing, and temporary permits. You can search by map-block-lot (MBL) number, street name, or the name of the person or company the permit was issued to. The city notes the results are for inquiry only and are not a legally binding record.
