Planned Unit Development (PUD)

Also known as: Planned Development District, Master Planned Development, PUD

A planned unit development is a zoning designation negotiated between a developer and a municipality that substitutes a custom, project-specific set of development standards for the underlying district's default dimensional rules, typically in exchange for public benefits such as open space, mixed uses, or affordable housing.

PUD zoning trades flexibility for negotiation: rather than applying uniform setback, density, and use rules parcel by parcel, the municipality approves a master plan and a binding set of standards tailored to the specific site, often allowing density transfers within the project (higher density in one area offset by preserved open space elsewhere), integrated mixed uses that a conventional single-use district would prohibit, and phased buildout over multiple years. In exchange, municipalities frequently extract public benefits—dedicated parkland, affordable housing set-asides, infrastructure contributions—codified in a companion development agreement. Because a PUD's standards are project-specific rather than generic, any material deviation from the approved master plan typically requires a formal amendment, which can be as time-consuming as the original approval and is a key diligence item when acquiring a site with existing PUD entitlements.
