Density Bonus Law: Concessions and Waivers

Sibley meets with Omar Hason to discuss Density Bonus Law. Density Bonus Law works today largely because of its use of concessions and waivers to overcome zoning code barriers that would make the projects impossible or infeasible. And yet the details of what exactly requires a concession vs. a waiver and when one can and can't use either often remains murky in practice. Sibley Simon and guest Omar Hason talk through their use in project entitlement. Host Sibley Simon - Workbench Principal and Impact Development Executive Guest Omar Hason - Senior Designer, Workbench Omar is passionate about architecture and all things design. He has wide-ranging experience working in most building typologies, including hospitality, sports arenas, theatres, healthcare, offices, and most of all, housing. --- Who Are The Infill Insiders? The Infill Insiders break down the highly complex process of infill housing development in California. Host and principal developer, Sibley Simon, shares Workbench's experience to teach developers and land owners how to use the many state housing laws to successfully develop infill housing, while showing jurisdictions what makes the process more efficient, and encouraging elected officials and anyone interested to face the big challenges that still remain in housing creation.

Calculating Permittable Density Part 3 of 3: Density Bonus Law & Special State Laws

In this third and final installment of the density calculation series, Sibley Simon and guest Clay Toombs cover alternative density calculation methods — additional state law pathways that may yield even more units than either units-per-acre or form-based density, but come with other strings attached. Episode 6 completes the full picture of how to calculate the density a developer can legally build in California as of 2026. Host Sibley Simon Workbench Principal and Impact Development Executive Guest Clay Toombs Clay has been an independent land-use consultant and contract project manager for 10 years. He holds a Master of Real Estate Development, a Master of Business Administration, and a B.S. in Aeronautical Management Technology, all from Arizona State University. --- Who Are The InfillInsiders?

Calculating Permitable Density Part 2 of 3: Density Bonus Law and Form Based Zoning

In this second installment of the density calculation series, Sibley Simon walks Serena Collins through form-based density—the method used when local zoning does not specify a units-per-acre standard. The episode explains how developers use Floor Area Ratio (FAR) as the controlling density measure, how to conduct a base density study to convert FAR into a unit count, and how density bonus law then multiplies that count. The discussion also covers strategic use of multifamily ADUs, the role of the Housing Accountability Act in resolving code conflicts, and the critical distinction between entitlement-stage and building-permit-stage decisions. Guest Serena Collins – Project Manager, Workbench / New Way Homes Serena has been with Workbench for 5 years managing project development and capital raising. She specializes in brownfield site cleanup and redevelopment funding and grant writing at both the state and federal level. Here’s what you’ll learn: What form-based density means and when it applies (hint: most commercial corridor and mixed-use zones)How Floor Area Ratio (FAR) becomes your controlling density measureThe base density study process — and why it requires an architect to design a building you’ll never constructWhy your base density study doesn’t need to be financially feasible (and how to use that to your advantage)How to resolve conflicts between your general plan and zoning code using the Housing Accountability ActThe three density layers: base density + stacked bonuses + multifamily ADU conversionsA real example of how 5-story zoning can yield an 18-story building Why This Matters: For developers and landowners: The base density study is the single most important step in maximizing your site’s housing capacity under California law. Getting it right — or getting it wrong — can mean dozens of units of difference on the same parcel.For housing policymakers: Understanding how form-based density translates into actual unit counts is essential for evaluating whether your zoning code is achieving its housing production goals.For multifamily investors: The density math is the feasibility math. Knowing how base density, bonus density, and ADU layering interact tells you whether a site pencils — before you ever write a check.Coming next: Part 3 covers the alternative density pathways — additional state law methods that may yield even more units, with different tradeoffs. That episode will complete the full 2026 picture of how to calculate the density you have the right to build on any California site.

Calculating Permitable Density Part 1 of 3 - Density Bonus Law & Units Per Acre

Episode Overview This episode launches a critical three-part series on how to correctly calculate the maximum permitable density of housing for any given parcel in California. Sibley argues this is among the most misunderstood aspects of California housing development—and that getting it wrong (which happens at least 95% of the time) means leaving significant housing capacity on the table. Part 1 focuses on parcels where density is expressed in units per acre, walking through the full calculation from general plan designation through density bonus law and multifamily ADU provisions. Host & Guest Host: Sibley Simon — Founder, Workbench (Integrated Real Estate Development, Santa Cruz, CA) Guest: Chris Hudon — Director of Development, Workbench (25 years of multifamily development experience in Colorado and Utah) Why This Guest Sibley specifically brought Chris on for Part 1 because Chris is an experienced multifamily developer—but not in California. His background in Colorado and Utah, where developers rely on local zoning, site constraints, and informal planning department consultations, makes him the perfect stand-in for what most developers do when entering the California market. Chris's fresh perspective highlights just how different—and counterintuitive—California's density calculation system is compared to the rest of the country.

Inside SB79 California's New Transit-Oriented Upzoning Law

What is SB 79? SB 79 is California's landmark transit-oriented housing upzoning bill, passed in 2025 after eight years of legislative attempts. The law requires certain jurisdictions to allow mid-rise apartment buildings (typically 4-7 stories) near major transit stops.
