Key Highlights from the New Legislation
SB 1211: A Game-Changer for Multifamily Properties
SB 1211 is poised to redefine housing density in California by allowing unprecedented flexibility for ADUs in multifamily developments. Here’s how this groundbreaking law changes everything:
- Double the Units (or More): Property owners can now add one detached ADU per existing unit on multifamily properties, up to 8 detached ADUs. For example, if you own a 4-unit apartment building, you can build 4 additional detached ADUs, potentially doubling your rental income.
- Interior Conversions Expanded: Up to 25% of a building’s interior space can now be converted into additional units. This expanded definition of "living space" includes areas not traditionally part of private residences, such as unused common areas.
- Clearer Guidelines: Ambiguities around "interior conversion" and parking requirements have been clarified, making it easier to plan and execute projects.
- New Development Applications: While this law doesn’t allow for speculative developments like building new 8-unit complexes with 8 detached ADUs, it opens doors for owners of existing properties to maximize density and cash flow.
This law is a game-changer for multifamily property owners, offering unparalleled opportunities to increase rental income and provide housing in high-demand areas. It’s a clear signal that California is embracing density as a solution to its housing crisis.
Other Key Highlights
- Amnesty ADUs (AB 2533):
- Legalizes existing non-compliant ADUs using health and safety standards instead of rigid building codes.
- Prohibits impact and connection fees unless new infrastructure is required.
- Cities must create clear approval processes and provide third-party inspection options for homeowners.
- Coastal Zone ADUs (SB 1077):
- Streamlines ADU approvals in highly regulated coastal areas like Venice Beach, making it easier to build in some of the most sought-after locations.
- JADU CEQA Exemption (AB 3057):
- Junior ADUs (JADUs) are now exempt from CEQA, removing a major bureaucratic hurdle for property owners.
- Streamlined Development Projects (SB 1123):
- Excludes ADUs from the 10-unit cap for streamlined approval under SB 684. This means you can add ADUs to your project without sacrificing eligibility for fast-track permitting.
- Permit Time Limits (SB 450):
- Establishes a 60-day "shot clock" for ADU permit approvals. Miss the deadline? The permit is automatically approved.
- Reduced Impact Fees (SB 937):
- Delays impact fees until a project’s final inspection or certificate of occupancy, saving developers significant upfront costs.
- Expanded Transit Definitions (AB 2553):
- Redefines “Major Transit Stops” to allow for taller ADUs within a half-mile of transit, boosting urban housing density.
- Historic Designation Reporting (AB 2580):
- Requires cities to include a breakdown of housing units denied due to historic designations, shedding light on how these rules affect housing.
- Builder’s Remedy Strengthened (AB 1893):
- Empowers homeowners in non-compliant cities to move forward with ADU permits, providing relief from local bureaucratic barriers.
- Attorney General Enforcement (SB 1037):
- Fines cities up to $50,000 per unit for non-compliance with housing laws, ensuring stricter enforcement and funding for affordable housing.
- Permit Extensions (AB 2729):
- Extends permit expirations to 18 months, giving property owners more time to complete their projects.
