In San Diego, Accessory Dwelling Units (ADUs) up to 800 sq ft—like the Alder two-bedroom ADU floor plan—benefit from streamlined, by-right approval processes. These units require reduced setbacks of just 4 feet from rear and side property lines and generally no additional parking if located near transit or built as a garage conversion. While standard zoning rules for lot coverage and open space still apply, the 800 sq ft size often simplifies the permitting process. Some properties may have additional requirements, such as coastal zone approvals or HOA considerations. Our team manages the full building process, securing necessary building permits and ensuring compliance with local building codes.

With the right design and careful consideration of the availability of space, you can comfortably fit two bedrooms in an 800 sq ft layout. Many L-shaped plans maximize flow and functionality by placing bedrooms on one side and living areas on the other. Each room can function as a bedroom suite, complete with closet space and access to a bathroom, offering privacy and comfort typically found in much larger homes. The result is an efficient, livable design that comfortably accommodates 4–6 people without sacrificing openness or style.

A 2-bedroom ADU typically ranges from 650 to 1,000 square feet, depending on how the layout is optimized for limited space. An 800 sq ft design is widely seen as the ideal balance—it offers additional space for a full kitchen, living area, and one or two bathrooms, while still remaining compact enough to meet most zoning and permitting guidelines. Smart use of vertical space and efficient layouts help make this size feel much larger than it is, providing comfortable, private living for families, guests, or tenants—all within a footprint that keeps construction costs manageable and regulatory hurdles low.

800 sq ft ADU floor plans are compact, efficient layouts designed to offer full living functionality within a limited footprint. Most include two bedrooms, one or two bathrooms, a kitchen, a living/dining area, and sometimes laundry space. These plans are ideal for multigenerational living, rental income, or guest accommodations, offering flexibility, affordability, and ease of permitting—especially in places like San Diego, where ADUs under 800 sq ft enjoy relaxed zoning restrictions.

The amount of material needed for an 800 sq ft ADU depends on the specific layout, construction methods, and desired finishes. However, on average, you can expect to use approximately 6,000 to 8,000 board feet of framing lumber for the walls, floors, and roof. The foundation and slab typically require about 10 to 15 cubic yards of concrete. For the interior, around 80 to 100 sheets of 4x8 drywall panels are common, along with 900 to 1,200 square feet of roofing materials, such as shingles or tiles. Additional components like flooring, insulation, doors, windows, plumbing, HVAC, and electrical systems will vary based on your design and materials selected. Partnering with a design-build firm like Better Place Design & Build ensures accurate material estimates, reduced waste, and a more streamlined construction process tailored to your specific site.

A well-designed 800 sq ft ADU floor plan incorporates all the essentials of a full-sized home within a compact, efficient layout. Most include two bedrooms, each offering privacy and typically featuring built-in closets. Depending on the needs of the homeowner, the floor plan may include one or two full bathrooms—an important feature for multigenerational living or rental scenarios. The heart of the unit is usually an open-concept living, dining, and kitchen area, which creates a spacious, airy feel despite the smaller footprint. Kitchens often include a pantry, dedicated fridge space, stove, sink, and sometimes an island with a built-in dishwasher. An in-unit laundry space, typically a tucked-away washer/dryer closet, adds convenience without sacrificing aesthetics. Lastly, the layout features well-planned circulation paths and a welcoming main entry that ensures seamless movement throughout the home. The Alder floor plan by Better Place Design & Build is a prime example, balancing form and function to make every square foot count.
