Houseal Lavigne is an urban planning, design, and technology firm based in Chicago, with an office in Los Angeles. Since 2004, we've helped communities across the country plan for what's next: comprehensive plans, zoning and development codes, downtown and corridor plans, and economic strategies built to actually get implemented.
We plan beyond the pretty picture. That means plans grounded in data, shaped by real community engagement, and communicated through visuals that help people see the choices in front of them.
We also build the tools planning has been missing. Our team pairs AICP-certified planners with GIS specialists, 3D visualization artists, and software developers. That combination produced Euclid HL, a GIS- and AI-powered planning and zoning assistant that answers questions in plain English, grounded in a community's own adopted plans and codes.
Our work has earned APA National Excellence recognition, 27 APA state chapter awards, 6 Esri Special Achievement in GIS Awards, and Esri's Most Innovative Partner Award. We're an Esri Gold Partner.
