Boston Emergency Services Evolved: A Decade of Growth-Driven Changes
City records show the current setup for fire, police and EMS stems from decisions made over the past decade in response to housing growth and transit strains.
How we reported this
Boston emergency dispatch centers handled 268,400 calls in 2025, up from 241,000 five years earlier, according to Fire Department logs released this week.
The increase reflects years of policy choices that expanded residential density while holding first-responder staffing levels nearly flat. Mayor Michelle Wu’s administration has prioritized new housing units in already crowded neighborhoods, yet the number of on-duty paramedics per shift has risen only 4 percent since 2021.
Dispatchers now route more ambulances to Dorchester’s Fields Corner and Jamaica Plain’s Hyde Square, where new multifamily buildings opened along Washington Street and Centre Street. The Boston Housing Authority added 312 units in those two neighborhoods between 2023 and 2025, bringing more residents who rely on 911 for medical issues previously handled through private clinics.
MBTA service disruptions have added to the load. After the Red Line derailment near Andrew Square in March 2024, crews responded to 47 extra medical calls in one week alone. Average response time for priority-one emergencies now sits at 7.4 minutes citywide, compared with 6.9 minutes in 2022, per department performance data.
Staffing and Budget Decisions
City Council budget documents from fiscal 2023 show the emergency services line item grew 9 percent while overtime costs climbed 22 percent. Union contracts signed that year locked in the current shift structure, limiting the number of new hires the department could bring on without additional overtime. Training for new EMTs still takes 16 weeks at the Boston EMS academy on Southampton Street, a bottleneck that has not changed since the program moved there in 2019.
Earlier reforms under the prior administration had focused on merging fire and EMS command structures, a step completed in 2020. That merger reduced administrative overhead but left fewer specialized medical supervisors available during peak hours.
Next Steps for Residents
Starting July 15, the department will post daily response-time maps on its public dashboard covering Dorchester, Jamaica Plain, Roxbury and the South End. Residents can sign up for text alerts through the city’s NotifyBoston system to learn when crews are operating under high volume. Officials say these tools will help callers decide whether to drive themselves to urgent-care centers on Massachusetts Avenue or wait for an ambulance.
