A Boston commissioner is a department head who runs one of the city’s agencies under the mayor’s direct authority. The mayor appoints each commissioner alone, without City Council approval, and most serve at the mayor’s pleasure. The specific powers of any given commissioner come from the special act of the Massachusetts Legislature or city ordinance that created the position, which is why a Police Commissioner, a Fire Commissioner, and the Public Health Commission’s Executive Director each operate under different rules.1American Legal Publishing. The Charter of the City of Boston – Section 35 Appointments by the Mayor
Where a Commissioner’s Authority Comes From
Boston’s City Charter is not one document. It grew over more than a century as a patchwork of special acts from the Massachusetts Legislature, each granting or reorganizing specific powers.2American Legal Publishing. The Charter of the City of Boston One result is that individual commissioners trace their jobs to different statutes from different eras. The Police Commissioner’s role comes from a 1962 act, the Fire Commissioner’s from an 1895 act, and the Public Health Commission from a 1995 act. Each carries distinct powers and varying degrees of independence from the mayor’s office.
The mayor’s cabinet includes roughly twenty department heads, organized around functional areas such as public safety, housing, streets, human services, and equity. Some cabinet leaders carry the title Commissioner. Others are called Chief or Director, but the structural relationship to the mayor is largely the same: they serve at the mayor’s direction and can be replaced during administrative transitions.3Boston.gov.

How Commissioners Are Appointed
Section 35 of the City Charter gives the mayor sole power to appoint all department heads and members of city boards. There is no City Council approval requirement. 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 they will perform. The mayor cannot consider political party affiliation or place of residence in making selections.
In practice, a new mayor can rebuild most of the cabinet almost immediately after taking office. No confirmation hearing, no council vote, no waiting period. The mayor evaluates candidates on professional background and policy alignment, then formalizes the appointment. That concentration of hiring power is a defining feature of Boston’s strong-mayor system, and it explains why leadership turnover at the department level tends to follow election cycles.
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 department rules, the Commissioner commands the entire force and appoints every police officer, each of whom is charged with preserving public peace, protecting life and property, and enforcing all laws and city ordinances.5Boston Police Department. Rules and Procedures
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 industry under Chapter 392 of the Acts of 1930.5Boston Police Department. Rules and Procedures The Commissioner also sets operational priorities, deciding how officers are deployed across neighborhoods and which units receive additional resources.
Civilian oversight sits outside the department. The Office of Police Accountability and Transparency, established by city ordinance, operates separately from BPD and 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 all civilian complaints of officer misconduct. The OPAT 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.

The Fire Commissioner
The Fire Commissioner leads the Boston Fire Department and oversees fire 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 Department Records – Mayors Approvals
The Commissioner also manages the department’s apparatus fleet and station footprint through a multi-year capital plan.10City of Boston. Fire Department Capital Budget The Fire Prevention division, which operates under the Commissioner’s authority, inspects properties and issues permits, licenses, and certificates tied 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 all state and local fire prevention laws and regulations.11Boston.gov. Fire Prevention This is where the Fire Commissioner’s authority most directly reaches private property owners and commercial landlords.
The Public Health Commission Executive Director
The Boston Public Health Commission stands apart from other city departments. It was established as a distinct body politic and corporate under Chapter 147 of the Acts of 1995.12City of Boston. Public Health Commission Operating Budget That legal structure gives the Executive Director a degree of operational independence other commissioners lack, including the authority to enter contracts and manage the commission’s finances without routing every decision through other city agencies.13City 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, alongside communicable disease control and a broad range of community health programs, including substance use treatment and harm reduction services.12City of Boston.

Public Works and Transportation Commissioners
Two commissioners handle the physical systems that keep Boston moving. Both fall under the Streets cabinet, and both answer to the mayor through the Chief of Streets.
The Public Works Commissioner directs construction, maintenance, and cleaning of roughly 802 miles of roadway, supervises solid waste and recycling contracts, maintains the city’s street lights, and operates two major drawbridges. The department also requires commercial waste companies to hold permits before operating in the city.14Boston.gov. Public Works
The Transportation Department Commissioner manages how people and vehicles move through Boston. Programs 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, and oversees Recharge Boston, the city’s zero-emission vehicle charging initiative.15Boston.gov. Transportation For large-scale development, the department reviews the traffic impact of major projects before they break ground.
Environment and Parks Commissioners
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
The Parks and Recreation Commission draws its authority from Chapter 185 of the Acts of 1875, Massachusetts General Laws Chapter 45, and Municipal Code Section 7.4. The 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 Once a park receives a name, only the commission can approve a renaming, and not until at least twenty years have passed.
Oversight, Performance, and Removal
Commissioners report to the mayor and are accountable for their departments’ results. The city tracks performance through Boston About Results, 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 such as 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. 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. The Police Commissioner is a partial exception in practice. The termination of Commissioner Dennis White in 2021 triggered a protracted court battle before the firing was upheld. For the rest of the cabinet, the charter’s default framework gives the mayor broad discretion.
