Air Pollution Control Commission

The Boston Air Pollution Control Commission works to maintain healthy air quality and noise levels in the City.

The Commission works to make our City a healthier and more comfortable place to live, work, and visit. We regulate activities that affect air quality and noise levels.

The Commission's programs and policies support our work to make Boston a carbon-neutral community by 2050. Reducing air pollution results in healthier air for Bostonians. We also reduce Boston's contribution to global climate change.

    Parking Freezes

    Parking freezes reduce air pollution caused by cars by limiting off-street parking in a given area. The Commission oversees the Downtown, East Boston, and South Boston Parking Freezes. You can view a map of parking freeze areas in the City.

    About our program

    Our parking freeze program is part of the Massachusetts State Implementation Plan (SIP). This plan ensures the state meets air quality standards under the federal Clean Air ActLearn more about Boston's parking freezes at our dedicated program page:

    Noise in Boston

    The Boston Municipal Code sets standards for reasonable noise levels. It also sets maximum acceptable noise levels for different times of day. An unreasonable level of noise is:

    • anything louder than 50 decibels from 11 p.m. to 7 a.m., or
    • anything louder than 70 decibels at any time, except for permitted construction.

    The Commission has developed regulations that apply to residential, business, and industrial districts. Our Commission and the Boston Police Department work together to enforce the rules on noise.


    Inspectional Services approves after-hours construction permits on a weekly basis. Find approved permits near you. You can also contact your neighborhood coordinator to learn about approved after-hours construction in your area.

    Building Energy Reporting and Disclosure Ordinance

    Buildings account for over seventy percent of greenhouse gas emissions in Boston. The Building Energy Reporting and Disclosure Ordinance (BERDO) requires that buildings over 35,000 square feet report their annual energy and water usage to the City. It also requires the City to make this data public. Buildings covered must also take steps to reduce their emissions every five years through energy actions or audits.

    Learn more about the BERDO Program

    The City is developing a building emissions performance standard to cut carbon from existing large buildings.

    Abrasive blasting and chemical cleaning

    Abrasive blasting uses water, sand, or other materials under high pressure to clean surfaces. Chemical cleaning uses chemicals and water to clean surfaces. If your project requires abrasive blasting or chemical cleaning, you will need to apply for a permit:
