Form-Based Coding is a revolutionary approach to zoning that has the power to inspire walkable neighborhoods, resilient communities, and thriving cities.
For over twenty years, our architects and urban designers have led the advancement of form-based code techniques and best practices. We have worked on over 60 Form-Based Codes (FBCs). In 2004, we co-founded the Form-Based Code Institute, a think tank that is now part of Smart Growth America. In 2008, we wrote what has been called the definitive book on FBCs. We are continuously evolving and advancing our application and best practices.
We know what makes a code effective. We established many of the graphic standards, system approaches, and usability components emulated today in many codes. So when you choose us, you can be confident that we’ll create a code that delivers results, implements your vision, and is easy to use.
Unmatched Depth of Knowledge and Experience with Form-Based Codes
Our coding experience began with small planning areas, including neighborhoods and downtowns, and evolved to include citywide corridor networks, citywide land development code updates, multi-jurisdictional countywide codes, and form-based bridges between FBCs and comprehensive/general plans. Because of that depth of expertise, we were asked to write the first development code for a rapidly growing city in West Africa. We have a clear track record to effectively tackle your coding project whether it’s small or large.
We are most proud that these codes are delivering results and helping communities. These codes have also been recognized with over a dozen local and national awards, including the Congress for New Urbanism Charter Award Grand Prize, multiple Driehaus Form-Based Code Awards, and two National APA Burnham Awards.
Objective Design Standards to Deliver Missing Middle Housing and Housing Choices
Not all Form-Based Codes have Building Types Standards, but they are at the core of most of our codes. We believe building types are the building blocks of great walkable urban places. This is partly because because they introduce (or re-introduce) a broader range of housing types into local development, and also because they help ensure high-quality built results.
Many building types, including Missing Middle Housing, cannot be effectively regulated by conventional zoning. These building types often have medium or high densities, which excludes them from single-family use zones, even though they are house-scale. Meanwhile, their small footprints and lower heights don’t fit the parameters or intent of existing multifamily and medium-density zones. So we’ve developed an effective way to regulate for them by including building type standards within our Form-Based Codes.
More Than a Great Code: Education, Buy In, and Built Results
To be effective, a coding project involves more than just writing the code itself. So we’ll first help you to lay the groundwork for your FBC, train your staff, review your procedures, and strategize how to completely update your code or make targeted fixes to establish objective design standards.
We’ll coordinate a multi-disciplinary team to effectively tackle challenges such as parking and street design, and engage and inform community perceptions around challenging topics including density. In the end, we’ll translate all of these elements into a high-quality built environment that your community wants.

"Opticos was an invaluable partner in helping Cincinnati achieve its goal of ‘Thriving Re-Urbanization.’ Their Form-Based Code was remarkably easy to use and has spurred confidence within the development community. Thanks to Opticos, the focus neighborhoods are seeing private sector investment that has not been seen in over 40 years.”

How to Use Building Types in Zoning
Building types can be useful in form-based codes where the goal is to enable a fine–grained mix of buildings of varied density and type in walkable neighborhoods. The approach of using building types is also effective in situations where permit streamlining is required and discretionary review is not allowed or significantly limited. For example, in California, Senate Bill 35 requires that only a community’s ‘Objective Design and Development Standards’ apply to multi-family or mixed-use projects. This means that more rather than less clarity in the standards and the community’s expectations is needed. Building types when prepared well offer that needed clarity.

Opening Doors to New, Context-Sensitive Development
Recent California state legislation (eg., SB 35, SB 330 and the Housing Accountability Act) stipulates that in certain situations, projects that qualify for streamlined review and processing must be designed and reviewed only through objective design standards. Marin County retained Opticos Design in 2019 to develop Objective Design and Development Standards (ODDS) for multifamily and mixed-use residential development in coordination with 11 separate jurisdictions within the County, the largest objective design standards application to date.

Building Types in Zoning, Part 2: Where?
As established in Part 1 of this series, we understand why it’s important to use building types. Now, let’s get into the next question: where? This post focuses on where building types are most effective, where they could be helpful but aren’t necessary, and where they are not necessary and should not be used.
