Our Signature Approach to Building ADUs in San Diego

Accessory dwelling units (also known as granny flats, in-law suites, companion units, and guest houses) have become very popular projects for homeowners and property investors alike.

An accessory dwelling unit is a worthwhile investment for those looking to maximize + modernize their living space or generate rental income. Planning an ADU build can feel overwhelming, with many options to consider depending on the size and orientation of your lot. An ADU can be built as part of an existing or to-be-built home, or detached and located as a separate structure from your main residence.

Ten Seventy Architecture will walk you through every option available for your project. All you have to do is share your vision + project goals with us and we’ll do the rest, from designing your ADU and securing the proper permits to finishing construction. Our team specializes in creating innovative ADUs, navigating the city’s notoriously complex codes to add extra design value to every build.
