This project is a full property transformation that turned a typical single-family house with a detached garage into a 5-unit investment property.

Originally, the site only had an 1,372 sq. ft. single-family residence and a detached garage. Through careful planning and site optimization, the property was redeveloped into a multi-unit layout consisting of a remodeled main residence, an SB9 unit, two detached ADUs, and one attached ADU.

The existing house underwent a major remodel to improve the overall layout, functionality, and living conditions while maintaining the original residential character of the property.

A new 667 sq. ft. attached ADU was added to the main structure, creating an additional independent living space that integrates naturally into the overall design.

Part of the existing residence was also converted into a new 481 sq. ft. SB9 unit, allowing the property to take advantage of California's SB9 regulations and significantly increase the usable residential density of the lot.

In the rear yard, the existing detached garage was converted into a new 361 sq. ft. ADU with an additional 142 sq. ft. expansion, transforming an underutilized structure into a fully functional rental unit.

The project also includes a brand-new 504 sq. ft. ADU, carefully positioned to maintain privacy, open space, and efficient circulation throughout the property.

The entire process — from initial measurements and feasibility analysis to permitting and final construction — was completed in approximately 8 months.

This project was designed specifically as an investment-focused development. By maximizing the property's potential and increasing the site from one residence to five separate units, the project created enough long-term rental value to help offset permitting and construction costs while generating strong ongoing income potential for the owner.

The final result is a highly efficient multi-unit residential property that demonstrates how ADU and SB9 regulations can completely transform a standard single-family lot into a profitable long-term investment.
