Zoning and Building Code Review Overview

Whether a property owner is planning to construct a new building or expand an existing one, the project must comply with the applicable zoning ordinance regulations and building codes that govern the property.

A project typically begins with review by the Zoning Department. During this stage, the proposed work is evaluated to determine whether it conforms to the requirements of the local zoning code.

A zoning ordinance is a local law that regulates the permitted use and development of land within a city, town, village, or county. Because zoning must reflect local conditions, each municipality typically maintains its own zoning code.

By contrast, the building code is generally a statewide code that addresses safety and technical requirements, including fire safety, structural loads, maximum occupancy, travel distances, and mechanical, electrical, and plumbing standards.

A qualified design professional should be familiar with the applicable zoning and building code requirements for the project.

Documents Typically Needed for a New Building or Expansion

If a property owner hires an architect to design a new building or expand an existing building, the owner should generally have a current survey that is signed and sealed by a licensed surveyor. The survey should include the following information:

• Zoning map number

• Lot number

• Block number, where applicable

• Property lines and related property-line information

• Lot width and lot area

• Building address and owner name

• Building configuration and location on the property

• Building dimensions, if the structure is very old and no plans or elevations are available

• Building type, such as residential or commercial

• Number of stories

• Zoning district

• Front, side, and rear yard setbacks

• Number of street parking spaces

• Location and dimensions of all accessory buildings
