AB 2533: New Opportunities for Legalizing Unpermitted ADUs in California
As California continues to tackle its housing crisis, accessory dwelling units (ADUs) are playing a key role in expanding housing options. However, unpermitted ADUs have long posed challenges for both property owners and municipalities.
Assembly Bill 2533 (AB 2533)—set to take effect on January 1, 2025—offers a lifeline to property owners by expanding the amnesty program for unpermitted ADUs and Junior ADUs (JADUs) built before January 1, 2020.
Key Benefits of AB 2533
- Simplified Standards: Assessments will focus on habitability rather than strict building codes.
- Fee Waivers: Retroactive impact, connection, and capacity fees are largely waived.
- Expanded Eligibility: ADUs built between January 1, 2018, and January 1, 2020, now qualify for amnesty.
This program makes it more affordable and straightforward for property owners to bring unpermitted ADUs into compliance.
Why This Matters
Legalizing unpermitted ADUs is about more than compliance—it’s about creating safer housing, protecting landlord-tenant rights, and helping municipalities meet their housing goals.
- Safety First: Ensures proper utility connections and safer living conditions.
- Fair Housing Protections: Legal clarity for both landlords and tenants.
- Stronger Communities: Helps cities accurately account for housing stock and secure funding.
How to Get Started
If you own an unpermitted ADU, here’s what to expect:
- Consult Local Planning Departments: Begin the permitting process.
- Schedule Safety Inspections: Meet habitability standards.
- Prepare for Upgrades: Address any necessary improvements.
Don’t let your unpermitted ADU remain in a legal gray area. AB 2533 provides a clear, cost-effective path to compliance, increasing your property’s value and ensuring peace of mind.
