Understanding ADUs in Altadena

Types of ADUs

Altadena allows various types of ADUs to accommodate different needs

Detached ADUs

Detached Accessory Dwelling Units (ADUs) are standalone residential structures built on the same lot as a primary home, offering independent living spaces complete with their own kitchens, bathrooms, and entrances. Often referred to as backyard cottages, granny flats, or carriage houses, detached ADUs provide flexible housing solutions that can accommodate extended family, generate rental income, or serve as home offices or guest houses. Unlike attached or internal ADUs, detached units are physically separate from the main residence, offering greater privacy for occupants. They are increasingly popular in urban and suburban areas seeking to address housing shortages and promote more efficient land use.

Attached ADUs

Attached Accessory Dwelling Units (ADUs) are a smart and efficient way to add livable space to your existing home. Built as extensions connected to the main residence—such as garage conversions or home additions—attached ADUs offer added privacy, flexibility, and rental income potential. They are ideal for multigenerational living or creating a private guest suite, all while increasing property value. Discover how an attached ADU can transform your space and maximize your home’s potential.

Garage Conversions

Transform your unused garage into a functional and stylish Accessory Dwelling Unit (ADU) to maximize your property’s value and create additional living space. Garage conversions to ADUs are a cost-effective way to add rental income potential, accommodate extended family, or create a private home office—all without the need for new construction. With proper planning and permits, your garage can become a fully livable unit that enhances lifestyle and investment.

Junior ADUs (JADUs)

Junior Accessory Dwelling Units (Junior ADUs or JADUs) are small, self-contained living spaces created within the walls of an existing single-family home. Typically no more than 500 square feet, JADUs offer an affordable and efficient housing solution by converting existing space, like a bedroom or garage, into a livable unit. Ideal for rental income, multi-generational living, or home offices, Junior ADUs are gaining popularity across California due to their streamlined permitting process and lower development costs. Explore the benefits of adding a Junior ADU to maximize your property’s potential.

Zoning and Building Regulations

Altadena’s regulations are designed to facilitate ADU development while maintaining neighborhood character, they are constantly evolving and changing. Here are some general ideas of zoning and building ADU regulations for Los Angeles:

Accessory Dwelling Units (ADUs) are subject to size limits that vary by location, but most regulations cap detached ADUs at 800 to 1,200 square feet. In many areas, size restrictions depend on factors like lot size, zoning, and whether the unit is attached or detached. Understanding local ADU size limits is crucial for compliance and maximizing your property’s potential. Always check your city or county’s specific ADU guidelines to ensure your project meets code.

In California, ADU (Accessory Dwelling Unit) setbacks refer to the required minimum distance between the ADU and property lines. As of recent state legislation, ADUs typically must be set back at least 4 feet from side and rear property lines, though local regulations may vary. These relaxed setback rules are designed to encourage housing development and make it easier for homeowners to add ADUs. Understanding local ADU setback requirements is crucial for maximizing space and ensuring compliance with California state laws.

In California, Accessory Dwelling Unit (ADU) height restrictions have been relaxed to encourage housing development. Detached ADUs are generally permitted up to 16 feet in height. However, if the ADU is located within half a mile of public transit or on a property with a two-story multifamily dwelling, the height limit increases to 18 feet. For attached ADUs, the maximum height can reach up to 25 feet or match the height of the primary residence, whichever is lower. These statewide standards aim to streamline ADU construction, though local jurisdictions may impose additional requirements
In California, Accessory Dwelling Unit (ADU) owner occupancy requirements have evolved to encourage more housing development. As of 2020, state law prohibits local governments from enforcing owner occupancy requirements on ADUs permitted between January 1, 2020, and January 1, 2025. This means property owners can rent out both the main home and the ADU without living on-site, increasing flexibility for homeowners and investors. However, individual cities may have additional regulations, so it’s essential to check local ordinances before building or renting an ADU.
In California, Accessory Dwelling Units (ADUs) are subject to a combination of state and local regulations aimed at ensuring design consistency and neighborhood compatibility. State laws provide a foundational framework, allowing ADUs up to 1,200 square feet and mandating streamlined approval processes. However, local jurisdictions can impose additional design standards, such as requiring the ADU’s exterior to match the primary residence in materials and color schemes, and adhering to specific roof pitches and setback requirements. These layered regulations ensure that while ADUs contribute to alleviating housing shortages, they also respect the existing neighborhood character and planning objectives.

Our initial consultation for Accessory Dwelling Unit (ADU) construction is a crucial first step in bringing your project to life. During this complimentary meeting, we assess your property, discuss your goals, review zoning and permitting requirements, and explore design options tailored to your needs and budget. This personalized approach ensures your ADU project starts with a clear vision and a solid plan, setting the foundation for a smooth and successful build.

Design and Planning

Design and planning for the construction of an Accessory Dwelling Unit (ADU) are crucial steps that ensure the project meets local zoning laws, maximizes space efficiency, and aligns with your property’s aesthetics. A well-designed ADU adds value to your home, provides flexible living options, and supports sustainable urban growth. By working with experienced architects and understanding permitting requirements early, homeowners can streamline the process and avoid costly delays. Proper planning also ensures your ADU meets energy efficiency standards and enhances long-term livability.

Permitting

The permitting process for constructing an Accessory Dwelling Unit (ADU) typically involves submitting detailed plans to your local building department for review and approval. This includes zoning compliance, structural design, utility connections, and adherence to local building codes. Securing the necessary permits ensures your ADU project meets legal and safety standards, helping you avoid costly delays or penalties. Working with experienced professionals can streamline the process and improve your chances of quick approval.

Construction

The construction process for building an Accessory Dwelling Unit (ADU) involves several key phases, starting with planning and permitting, followed by site preparation, foundation work, framing, and utility installations. Once the structure is built, interior finishes such as insulation, drywall, flooring, and fixtures are completed. Throughout the process, ADU construction must comply with local building codes and zoning regulations to ensure safety and quality. Partnering with experienced ADU contractors helps streamline the timeline and ensures your secondary dwelling is built efficiently and to code.

Final Inspection and Handover

The final inspection and handover process for building an Accessory Dwelling Unit (ADU) is a crucial step to ensure the project meets all local building codes and safety standards. During the final inspection, officials assess structural integrity, plumbing, electrical systems, and overall code compliance. Once approved, a certificate of occupancy is issued, allowing the unit to be legally inhabited. The handover includes a walkthrough with the contractor to review completed work, provide maintenance tips, and deliver necessary documentation. This step marks the official completion of your ADU, ready for use or rental.
