Brookline’s $65 million plan to modernize its aging fire stations gets a public update Tuesday, July 14, as the Building Commission reviews construction progress at Fire Stations 1 and 4 and discusses the future of Station 5.

The hybrid meeting begins at 6 p.m. at Town Hall, 333 Washington St., fourth floor. Residents can also attend virtually through Zoom or by phone.

Commissioners are scheduled to vote on requisitions and change orders for the Station 1 and Station 4 projects. The agenda does not list dollar amounts but also includes an update on Station 5, one of the more challenging pieces of the long-term overhaul.

The town’s plan calls for renovations or replacements at Stations 1, 4, 5, 6 and 7 over roughly a decade. Construction began at Station 4 in Chestnut Hill in 2025, with Station 1 expected to follow.

Station 5, located at 49 Babcock St. near Coolidge Corner, remains the biggest question mark. Built in 1965, the station’s aging design and tight layout have led Fire Chief John Sullivan and firefighters union president Justin Robinson to argue that a full replacement makes more sense than a renovation.

The town hired CambridgeSeven for a $58,500 feasibility study on Station 5’s future. It is unclear whether that study has been completed.

The project is aimed at more than updating old buildings. Planned improvements include fossil-fuel-free heating and cooling systems, individual bathrooms and showers, and better separation between living areas and contaminated firefighting gear.

Officials have also raised concerns about cancer risks tied to firefighter exposure. The renovations are designed to better protect crews from carcinogens brought back on equipment and clothing.

Brookline voters approved the project through a debt exclusion in 2022. The current estimate is $65 million, with any additional borrowing requiring Town Meeting approval.

The Building Commission meeting agenda also includes updates on the Pierce School project and a vote related to the Larz Anderson skating rink.

Residents can follow the project discussion Tuesday night through the Building Commission meeting.
