Which authority sets minimum lot sizes, building heights, and setbacks for home construction?

The Zoning Board is the correct authority for setting minimum lot sizes, building heights, and setbacks for home construction. This body is primarily responsible for interpreting and enforcing zoning laws, which dictate how land can be used and how structures can be built in a given area. Zoning regulations are critical because they ensure that land use is consistent with the community's development goals and land-use plans. They help maintain the character of neighborhoods and prevent overcrowding or incompatible uses.

The responsibilities of the Zoning Board often include evaluating and deciding on applications for zoning variances, which allow for deviations from the established zoning regulations under certain circumstances. This means they play a central role in making decisions about what types of buildings can be constructed and their dimensions within specific areas.

In contrast, the Building Commission typically focuses on ensuring that buildings comply with safety codes and construction standards rather than zoning regulations. The Planning Department is often involved in the broader aspects of urban planning and land use, but it does not enforce the specific zoning regulations. The Architectural Review Board generally advises on the aesthetics and design of buildings, rather than enforcing zoning laws related to lot sizes and setbacks.
