AB 6 – Exploring Simpler Codes for Small Apartments
AB 6 – Exploring Simpler Codes for Small Apartments
Could triplexes and fourplexes get easier to build? This bill says maybe.
AB 6 launches a statewide study to explore whether smaller residential buildings—typically between 3 and 10 units—can be permitted under the simpler California Residential Code (CRC) rather than the more complex and expensive California Building Code (CBC).
If adopted, this change could make small-scale housing development significantly faster, cheaper, and more accessible, especially for homeowners and small infill developers.
This is a forward-thinking effort to remove one of the key technical and financial barriers that prevents many “missing middle” housing projects from moving forward.
What This Means for You
While AB 6 is currently a study—not a law change yet—it signals the state’s intent to rethink overly complex code requirements for modest apartment buildings. That’s great news if you’re considering:
Building a triplex, fourplex, or small apartment on your lot,
Adding multiple ADUs or converting an existing structure into smaller units,
Creating housing for extended family, renters, or shared living, and
Wanting to do it without the high costs of full commercial code compliance.
Potential Future Benefits:
Lower construction and engineering costs,
Simpler permitting and plan check processes,
Faster timelines due to less complexity,
More small-scale housing in walkable, residential neighborhoods.
And even while the study is underway, it’s still a great time to plan or begin a modest multi-unit project—because the market and legislative climate are increasingly in your favor.
