Law + Planning + Design=Zoning

We write zoning codes that are clear, consistent, user-friendly, equitable, and defensible, so the rules match the community's vision instead of getting in its way.

Southold, New York

Three disciplines, one firm

Law

Codes that hold up. Our lawyers have written and defended zoning ordinances in court and at the dais, so every provision is drafted to be enforceable and defensible.

Led by a former Chief Counsel for Land Use and Planning, City of Cincinnati.

Planning

Codes that implement the plan. Our city planners have run planning departments in major U.S. cities and know how regulations work in practice, not just on paper.

Planners who have served as Planning Directors and FAICP-credentialed practitioners.

Design

Codes that people can use. Our urban designers and preservationists make regulations visual, intuitive, and readable by residents, staff, and applicants alike.

Development Pattern Districting, our intuitive approach to zoning.

Zoning that advances your community's vision

Clear. Consistent. User-friendly. Equitable. Defensible. Our proven process is built to solve your problem efficiently and effectively.

Year ZoneCo was founded

Founded on three zoning principles

Every code we write starts here. If a regulation doesn't serve one of these, it doesn't belong in the code.

  1. Zoning should regulate only what needs to be regulated to advance the vision and promote public health, safety, and welfare.
  2. Zoning should respect both existing and desired development patterns.
  3. Zoning should be the implementation of a plan, not a barrier to achieving desired outcomes.
