Big Changes to California ADU Laws in 2025 – What You Need to Know
Big news for California homeowners: New ADU laws are coming in 2025, and they’re making it easier than ever to legalize, build, or expand Accessory Dwelling Units (ADUs). If you’ve been thinking about adding an ADU to your property, now’s the time to pay attention.
Here’s a quick breakdown of what’s changing:
-
AB 2533: Legalizing Unpermitted ADUs
Have an unpermitted garage conversion or unit? Don’t worry. This law lets you legalize your ADU without expensive upgrades or penalties. Plus, inspections will remain confidential—no fear of being reported. -
SB 1211: More ADUs on Multifamily Properties
If you own a multifamily property, you can now add one detached ADU per unit, up to eight ADUs. You’ll also get more flexibility with parking and converted spaces. -
SB 937: Impact Fee Relief
Building an ADU over 750 square feet? You’ll no longer have to pay impact fees upfront. Instead, fees will be collected at the final inspection, making cash flow during construction much easier. -
SB 1077: Simplified Coastal Zone ADUs
Building in a coastal area? New guidelines make the approval process clearer, faster, and more predictable while still protecting the environment.
These changes are a game-changer for homeowners like you. Whether you want to legalize an existing unit, generate rental income, or add living space for your family, 2025 offers exciting opportunities.
