Detached 500 SF ADU in Albany with modern exterior

500 SF Detached ADU in Albany

This 500-square-foot detached ADU in Albany transforms an underused backyard area into a highly functional and rental-ready living unit that meets modern California energy and zoning standards.

Aging backyard space with limited functionality

The existing rear yard lacked usable living space, suffered from poor drainage, and offered no insulated or code-compliant structures. The homeowners needed a compact ADU that would provide privacy, natural light, and long-term rental income potential.

Light-oriented layout + efficient utility routing

The design prioritizes natural light by orienting windows toward the southern exposure while maintaining privacy from adjacent homes.

A simple rectangular footprint allows cost-efficient framing, and a consolidated mechanical core minimizes plumbing runs, reducing construction cost.

High-efficiency insulation, mini-split HVAC, and Title 24-compliant glazing deliver comfort with minimal operating expenses.
