What Is an Accessory Dwelling Unit (ADU)?
An accessory dwelling unit (ADU) is a secondary housing unit located on a single-family residential lot. These structures can take various forms, including a converted garage, a basement suite, or a detached unit in the backyard of your Los Alisos property.
ADUs serve multiple purposes. They can provide housing for family members, generate rental income in Westminster's competitive housing market, or serve as a guest house for visitors looking to enjoy Southern California's mild climate, with July, June, and September being the most pleasant months in the area.
Key features of ADUs include:
- Independence: ADUs have separate entrances and their own kitchen and bathroom facilities.
- Size: They typically range from 200 to 1,200 square feet, aligning well with Los Alisos homes that average 620-1,248 square feet.
- Types: Common types include attached, detached, and units created from existing structures.
Building an ADU can enhance property value and address housing shortages in Orange County. As certified ADU specialists with several completed projects, we can help navigate Westminster's local zoning laws and building codes
to ensure compliance, especially important in this established community with specific HOA guidelines.

Designing for Small Spaces
Designing ADUs and garage conversions often involves optimizing limited space. Our space-saving design system utilizes creative storage solutions, multi-functional furniture, and strategic layout planning to maximize every square foot.
In our designs, we prioritize:
- Furniture Layout: Strategic arrangement for fluid movement in compact spaces.
- Natural Light: Large windows to enhance roominess, capitalizing on Westminster's abundant natural sunlight.
- Outdoor Access: Connecting indoor spaces to outdoor areas to expand perceived living spaces.
Converting Detached vs. Attached Garages
When we consider detached versus attached garages in Los Alisos, each option has unique advantages and design challenges, influenced by the community's layout and climate considerations.
Detached Garages:
- Often provide more privacy since they are separate from the main home.
- Allow design flexibility without affecting the primary structure.
Attached Garages:
- Offer convenience, especially if they share walls with living spaces.
- Enable easier access to utilities, which can streamline conversion processes.
Our team is experienced in both types of conversions, with specialized equipment and techniques for each. We provide comprehensive structural assessments and foundation evaluations before beginning any project, ensuring your conversion will remain durable and problem-free across Westminster's seasonal changes.
