The Ultimate Guide to ADU Regulations in California 2024: What Homeowners Need to Know


Creating an Accessory Dwelling Unit (ADU) in California will become more accessible and flexible in 2024, thanks to recent legislative changes. This guide briefly outlines the key aspects of ADU regulations for those interested in exploring this option, such as homeowners in Fallbrook, California, serviced by Coldwell Banker Village Properties.

Critical Changes in ADU Laws for 2024

1. AB 1033: This law has made a significant shift by allowing the sale of ADUs separate from the primary residence, with local agencies authorized to adopt ordinances for selling ADUs as condominiums. Homeowners may need to establish a Homeowners Association (HOA) for managing common property between the ADU and the primary residence.

2. AB 976: Extends the prohibition on local agencies from imposing owner-occupancy requirements on ADUs. This change allows more flexibility for homeowners, who can rent out their primary residence and the ADU without needing to live on the property.

3. AB 434: All California cities and municipalities must have pre-approved ADU plans in place by January 1, 2025. This aims to streamline the ADU planning and construction process.

Other Notable Changes

– Height Restrictions: The minimum height limit for detached ADUs is now 16 feet, with certain exceptions allowing up to 18 or 25 feet depending on location and attachment to the primary dwelling.
– Setback Requirements: Restrictions on front setbacks have been eased, especially for smaller ADUs less than 800 sq. ft.
– Fire Sprinkler Requirement: The need for automatic fire sprinklers in ADUs has been removed, simplifying construction.
– Owner-Occupancy Requirements: Lifting these requirements offers more flexibility in renting out ADU properties.
– 60-Day Rule: Local agencies must respond to ADU applications within 60 days, streamlining the approval process.

Practical Implications for Homeowners

The changes in ADU laws present new opportunities for homeowners in California. ADUs can provide additional living space, a source of rental income, and flexibility in property utilization. They can be a viable housing solution for extended families or create additional income sources.
