The Harrison ADU

The Harrison ADU is a perfect case study of "house hacking" as the front rental unit offsets the mortgage cost making this a positive cashflow property. Other unique features include a clean minimalist interior, energy efficient design and a high degree of privacy despite being on a tight urban lot in the Logan Heights neighborhood of San Diego.

The Everett ADUs

The Everett ADUs is an awesome showcase of how multiple ADUs can be fit on one lot with smart planning. By adding two ADUs behind the main house, our client is able to generate rental income from three units. This shows how ADUs add much-needed housing in San Diego while also generating passive income for the owner.
