Modern and contemporary designs are common, featuring clean lines, large windows, and minimalist finishes. Two-bedroom family-friendly layouts and one-bedroom retreats are both popular, often with smart storage and dedicated laundry areas. Other sought-after styles include L-shaped configurations, garage conversions, and cozy cottage or farmhouse-inspired designs. Regardless of style, the focus is on functionality, natural light, and flexibility in a compact footprint.

To make the most of 800 sqft, prioritize open-concept layouts, which eliminate unnecessary walls and promote light and flow. Use multi-functional furniture like Murphy beds and storage ottomans, and install built-in or vertical storage to free up floor space. Opt for compact kitchens with islands that double as prep and dining areas, and reduce dead space by minimizing hallways and using pocket doors. Incorporating large windows or outdoor extensions like patios also helps visually and functionally expand the space.

A well-designed 800 sqft ADU should include 1–2 private bedrooms, at least one full bathroom, and an open-concept living and dining area to enhance space and light. A functional kitchen with modern appliances and ample storage is essential, along with in-unit laundry and efficient entry or mudroom space. Key features like built-in storage, natural light, outdoor access, and flexible-use rooms (e.g., office or guest area) add livability. Smart design touches like minimal hallways, pocket doors, and multi-use furniture help maximize comfort and efficiency.

Zoning regulations in San Diego County are ADU-friendly, especially for units up to 800 sqft. These ADUs are exempt from lot coverage, floor area ratio (FAR), and open space rules, offering greater design freedom. Minimum setbacks are just 4 ft on the sides and rear, and front setbacks can't be used to block construction. Height, fire safety, and coastal zone rules may still apply, but no parking is required in most cases. These relaxed regulations are intended to simplify and encourage the development of modest-sized ADUs.

An 800 square foot floor plan typically fits 2 bedrooms comfortably, along with a bathroom, kitchen, and open living space. This layout offers a good balance between privacy and livability.

For most homeowners, 2 bedrooms is the ideal fit for function and space efficiency in an ADU or small home.

For ADUs and small homes, 2 people is the most common and functional fit.
