Boston’s commissioners are the mayor-appointed department heads who run the city’s major agencies, from the Police and Fire departments to Public Health, Public Works, Transportation, Environment, and Parks and Recreation. They sit on the mayor’s cabinet, serve at the mayor’s direction, and are hired without City Council approval. Roughly twenty department leaders make up that cabinet, and together they handle most of what residents experience as city government.1American Legal Publishing. The Charter of the City of Boston – Section 35 Appointments by the Mayor
Where Commissioners Fit in Boston’s Government
Boston’s City Charter is not one document. It grew over more than a century as a series of special acts from the Massachusetts Legislature, each granting or reorganizing specific powers.2American Legal Publishing. The Charter of the City of Boston That history matters because individual commissioners draw authority from different statutes passed in different eras. The Police Commissioner’s role traces to a 1962 act, the Fire Commissioner’s to an 1895 act, and the Public Health Commission to a 1995 act. Each carries distinct powers and a different degree of independence from the mayor’s office.
The cabinet is organized by function: public safety, housing, streets, human services, equity, and so on. Some cabinet leaders carry the title “Commissioner,” others are called “Chief” or “Director,” but the structural relationship is the same. They report to the mayor and can be replaced during administrative transitions.3Boston.gov. City of Boston Government
The Police Commissioner
The Police Commissioner holds the highest authority within the Boston Police Department. The position was originally a gubernatorial appointment, but Chapter 322 of the Acts of 1962 transferred that power to the mayor.4State Library of Massachusetts. Massachusetts Acts and Resolves – 1962 Chapter 0322 Under the department’s rules, the Commissioner commands the entire force and appoints every police officer, each charged with preserving public peace, protecting life and property, and enforcing all laws and ordinances.5Boston Police Department. Rules and Procedures
The role reaches beyond general law enforcement. The Commissioner designates administrative hearing officers for disciplinary proceedings, appoints the Harbor Master, and retains regulatory authority over the city’s hackney carriage (taxi) industry under Chapter 392 of the Acts of 1930. The Commissioner also sets deployment strategy and department priorities.5Boston Police Department. Rules and Procedures
Civilian Oversight Through OPAT
The Office of Police Accountability and Transparency (OPAT) was established by city ordinance to operate independently of BPD. It runs three internal boards, including the Internal Affairs Oversight Panel, which reviews Internal Affairs Division decisions for thoroughness and fairness.6Boston.gov. Police Accountability and Transparency
OPAT staff investigate civilian complaints of officer misconduct and support the Commission’s review of department policies. The Commission can compel testimony and documents through subpoena power, enforceable by a two-thirds vote and backed by Superior Court contempt proceedings.7City of Boston. Ordinance Establishing an Office of Police Accountability and Transparency The office also conducts racial equity assessments of BPD policies, analyzes Field Interrogation and Observation data for disparities, and tracks reform progress. For everyday policing decisions, this is the accountability channel that operates separately from the mayor’s authority to hire or fire the Commissioner.
The Fire Commissioner
The Fire Commissioner leads the Boston Fire Department and oversees suppression and emergency response. The role dates to 1895, when Section 9 of Chapter 449 of the Acts of 1895 abolished the former Board of Fire Commissioners and placed the department under a single executive.8City of Boston Archives and Records Management Division. Guide to the Fire Commissioner Records Under this structure, the Chief Engineer serves as the executive officer directing the daily work of department members.9City of Boston. Guide to the Fire Department Records – Mayors Approvals
The Fire Prevention division, which operates under the Commissioner’s authority, inspects properties and issues permits, licenses, and certificates related to fire safety. That includes smoke and carbon monoxide detector compliance for residential property sales, environmental property searches, and fire report requests. A Legal Unit within the division enforces state and local fire prevention laws.10Boston.gov. Fire Prevention This is where the Fire Commissioner’s authority most directly touches private property owners and commercial landlords.
The Public Health Commission Executive Director
The Boston Public Health Commission is not like other city departments. It was established as a distinct body politic and corporate under Chapter 147 of the Acts of 1995, which gives the Executive Director operational independence other commissioners lack, including the ability to enter contracts and manage the commission’s finances without routing every decision through other city agencies.11City of Boston. Boston Statutes and Ordinances – Acts of 1995 Chapter 147
The commission runs Boston’s Emergency Medical Services, which carried an operating budget of over $85 million in FY25, along with communicable disease control and a broad range of community health programs.12City of Boston. Public Health Commission Operating Budget The Executive Director also serves as the city’s top public health official and coordinates with state agencies on regulatory compliance and disease surveillance. On the ground, the commission operates substance use treatment and harm reduction programs, deploys Neighborhood Engagement Teams in areas like Nubian Square and East Boston, and runs a Mobile Sharps team that manages eleven outdoor syringe disposal kiosks across the city.13Boston.gov. Recovery Services
Streets: Public Works and Transportation
Two commissioners handle the physical systems that keep the city moving, and both sit under the Streets cabinet reporting to the Chief of Streets.
Public Works
The Public Works Commissioner directs construction, maintenance, and cleaning of roughly 802 miles of roadway. The department supervises contracts that remove about 260,000 tons of solid waste annually, runs a recycling program that diverts about 44,000 tons per year, maintains 68,055 city-owned street lights, and operates two major drawbridges.14Boston.gov. Public Works The department aims to resurface more than 30 miles of roadway each year and requires commercial waste companies to hold permits before operating in the city.
Transportation
The Transportation Commissioner manages how people and vehicles move through the city, with programs centered on access, safety, and quality of life.15Boston.gov. Transportation Key initiatives include Vision Zero, which aims to eliminate fatal and serious traffic injuries on city streets by 2030, and Neighborhood Slow Streets, a traffic-calming approach for residential areas. The department also runs the Resident Parking Program, manages towing and booting operations, administers bus stop improvements, oversees the Recharge Boston zero-emission vehicle charging initiative, and reviews the traffic impact of large development projects before they break ground.
Environment and Parks
Environment
The Environment Department leads Boston’s push toward carbon neutrality by 2050. Its work includes the Building Emissions Reduction and Disclosure Ordinance, which sets net-zero requirements for large buildings, and Boston Community Choice Electricity, which gives residents more control over their electricity sourcing. The department also runs the Air Pollution Control Commission and the Conservation Commission.16Boston.gov. Environment
Parks and Recreation
The Parks and Recreation Commission oversees land acquisition for parkland, enforces design regulations, reviews construction within 100 feet of any public park or parkway, and controls the naming of parks and placement of memorial plaques.17Boston.gov. Parks and Recreation Commission
How Commissioners Are Appointed
Section 35 of the City Charter gives the mayor sole power to appoint department heads and members of city boards. There is no City Council approval. The only exceptions are the school committee and positions the governor appoints.1American Legal Publishing. The Charter of the City of Boston – Section 35 Appointments by the Mayor Appointees must be recognized experts in their field or have special training for the work. The mayor cannot consider political party affiliation or place of residence when making selections.
The practical effect: a new mayor can rebuild the entire cabinet almost immediately after taking office. No confirmation hearing, no council vote, no waiting period. That concentration of hiring power is a defining feature of Boston’s strong-mayor system and explains why department leadership tends to turn over with election cycles.
How Commissioners Are Held Accountable and Removed
Commissioners answer to the mayor for their departments’ results. The city tracks performance through the Boston About Results program, which requires administrators in over forty departments to update performance data monthly. That data feeds web-based scorecards and a Mayor’s Dashboard organized around core service areas like public safety, basic city services, and economic development.18City of Boston. Boston About Results – A Data-Driven Boston
The mayor convenes monthly cabinet data meetings to review performance and guide policy. Departments also measure against Service Level Agreements that set benchmarks for on-time delivery of city services, and during the annual budget process, the Office of Budget Management requires each department to evaluate its performance measures and use prior-year results to justify funding requests.18City of Boston. Boston About Results – A Data-Driven Boston
Most commissioners serve at the pleasure of the mayor and can be replaced at any time without a stated reason. That at-will structure allows quick leadership changes when priorities shift or performance falls short. The Police Commissioner’s removal has historically involved more legal complexity; the 2021 termination of Commissioner Dennis White triggered a protracted court battle before the firing was upheld. For the rest of the cabinet, the charter gives the mayor broad discretion.
