San Francisco ADU Solutions

San Francisco ADU Solutions is an ADU design-build and construction company serving homeowners in San Francisco and surrounding Bay Area communities. The company provides an end-to-end ADU process covering design, engineering, permitting, financing assistance, construction management, and construction, with the goal of taking homeowners from initial site assessment through final inspection.

An accessory dwelling unit (ADU) — also referred to as a granny flat, in-law suite, backyard cottage, or secondary dwelling unit — is an additional residential unit located on the same property as a primary home. San Francisco ADU Solutions works with several common ADU configurations:

1. Attached ADU: An ADU connected to the primary residence, allowing homeowners to add living space while sharing a wall or portions of existing infrastructure.
2. Detached ADU: A separate structure built elsewhere on the property, providing an independent living space for family members, guests, or rental use.
3. Garage Conversion: An existing garage can be transformed into a functional ADU, making use of an existing structure rather than constructing an entirely new building.
4. Junior ADU (JADU): A smaller living unit created within an existing single-family residence, providing an additional housing option without requiring a separate detached structure.

What San Francisco ADU Solutions Offers Beyond Construction

San Francisco ADU Solutions presents itself as a full-service ADU contractor, handling the major stages of an ADU project under one coordinated process. Its services include ADU site assessments, architectural design, engineering, permitting, financing assistance, construction management, and construction.

The company’s ADU site assessment service evaluates a property’s feasibility, including zoning considerations, property lines, setbacks, utility connections, and potential construction challenges. This early assessment is intended to help homeowners understand what can realistically be developed before investing heavily in design and construction.

For design, the company prepares ADU plans intended to comply with San Francisco building codes and local regulations. Its engineering services address the structural design and calculations needed to prepare an ADU for construction.

Permitting is another major component of its service. San Francisco ADU Solutions handles the preparation and submission of plans and documentation to the relevant city departments and helps navigate local requirements involving setbacks, height limits, zoning, and historic-district considerations where applicable.

The company also provides ADU construction management, coordinating contractors and project activities from beginning to completion. Its website states that the construction process generally takes approximately 4–6 months, while the complete design and permitting process can extend the overall project timeline to roughly 12–18 months, depending on the project and site.

For homeowners concerned about financing, San Francisco ADU Solutions also provides ADU financing assistance, connecting homeowners with lenders and potential financing options for their projects.
