The Board of Zoning Appeal (BZA) has an important role in decisions that help shape the use and appearance of buildings in our community. Under the Cambridge Zoning Ordinance, certain uses and types of development may require a variance, special permit, or a comprehensive permit from the BZA, a quasi-judicial body that conducts public hearings on all applications and appeals before it and issues decisions.
