Bump-Out Accessory Dwelling Units (ADUs)
A Bump-Out Accessory Dwelling Unit (ADU) is a strategic extension added to an existing structure, typically the primary residence, to create additional living space. Unlike detached or garage-conversion ADUs, a bump-out involves expanding outward from your home to incorporate a functional unit with a kitchen, bathroom, bedroom, and living area. It’s an excellent choice for homeowners with limited space who want to maximize their property’s potential without sacrificing a separate structure.
Why Consider a Bump-Out ADU?
Efficient Use of Space
Utilize unused yard or side space to seamlessly add living quarters to your home.
Boosts Property Value
Adds usable square footage and enhances the overall market value of your property.
Cost-Effective Solution
Lower costs compared to building a detached unit due to shared walls and utilities.
Versatile Applications
Rent out the space for additional income. Provide housing for family members or guests. Create a private home office, gym, or studio.
Design and Features
Bump-Out ADUs are designed to blend functionality and aesthetics with your existing home. Popular features include:
- Seamless Integration: Matches exterior finishes and rooflines for a unified appearance.
- Smart Use of Space: Optimized layouts to maximize comfort in smaller areas.
- Energy-Efficient Materials: Modern insulation, windows, and energy-saving appliances.
- Custom Interiors: Tailored designs for bedrooms, offices, or multi-purpose spaces.
- Enhanced Access: Separate entrances for privacy and convenience.
Key Regulations to Know
Bump-Out ADUs must comply with local zoning laws and building codes. Important considerations include:
- Size Restrictions:
- The size of the bump-out typically depends on your lot size and local zoning rules, often ranging between 150-500 sq. ft.
- Setbacks:
- Ensure compliance with distance requirements from property lines and neighboring structures.
- Structural Integration:
- Requires compatibility with the foundation and framing of the main residence.
- Utilities:
- Usually shares existing water, sewage, and electrical systems, reducing installation costs.
- Permits:
- Building and zoning permits are mandatory; ADU360 handles all regulatory aspects for you!
Costs and Financing Options

- Construction Costs:
- Typically ranges between $50,000 and $150,000, depending on the size and finishes.
- Financing Options:
- Explore home equity loans, construction loans, or local incentives for ADU projects.

Why Build an ADU in Southern California?
Southern California homeowners build ADUs for various reasons. Whether you’re considering housing family members or seeking additional income, ADUs offer flexible solutions that enhance your property’s functionality and value. Notably, a 2021 survey by Generations United found that 26% of Americans live in multigenerational households, up from 7% in 2011, indicating a growing trend toward such living arrangements. ADUs provide a practical means to accommodate this shift, offering independent yet connected living spaces for aging parents or extended family members.
