Missing Middle Housing
Walkable, attainable communities people love to call home
Opticos principal Daniel Parolek inspired a new movement for housing choice in 2010 when he introduced the concept of the “missing middle” in American housing. Today, Opticos creates innovative architectural designs to help build walkable communities with unique, diverse housing choices that are attainable for all.

Zoning codes for
people-centered places
Opticos is a world leader in zoning reform for walkable, sustainable communities. We didn’t create form-based coding, but we’ve been trailblazers in the field for more than 20 years. We are experts in understanding how the form of buildings will shape community spaces, and we can simplify the process of introducing form-based codes with a predictable build-out.

This article was originally published in the American Planning Association, California Chapter – Northern Section newsletter authored by Stefan Pellegrini, AICP, Opticos Design Principal and Jillian Zeiger, AICP, Senior Planner at the County of Marin.

2023 Missing Middle Solutions and Car-Free Urbanism Road Tour
Opticos is hitting the road! Come join Daniel Parolek at one of his upcoming speaking events to discuss all things walkable urbanism-related, including the state of Missing Middle Housing applications around the world, including Opticos’ latest Missing Middle Scans and Deep Dives™, a County-wide Zoning Toolkit for Marin County intended to deliver much-needed housing options, and Housing Plans for various cities including Modesto and Sacramento, California, the latest updates on the implementation of Culdesac Tempe, the county’s first car-free community built from scratch and Prairie Queen, the country’s first 100% Missing Middle Neighborhood which utilizes the Missing Middle Neighborhood Kit™. There will be some frank discussions about existing barriers for implementing walkable urbanism, why we have not made more progress enabling it, and what organizations are leading the way in these conversations.
