Our Story

Otto — a sister company of Homestead — has spent the last 3 years designing, permitting, and building ADUs across the Los Angeles area. Our units have helped homeowners expand living space, generate rental income, and bring family closer together.

Homestead now lives on helping homeowners subdivide their lots under California's new Senate Bill 9.

Why Homeowners choose Otto

Architectural Expertise

The Otto team is led by trained architects who know how to design beautiful spaces, vet contractors, and provide quality control over construction.

Transparent Process

Our customers receive a detailed scope of work, clear pricing estimates, and coordinated drawing sets — so they always can make informed decisions.

Design Driven

We embed great design into every step of the project delivery process in order to transform the chaos of construction into an exciting and joyful experience.

Construction, Managed

Unlike other ADU providers, we fully manage the construction process and your project’s selected Contractor. Sit back and enjoy the progress!

Procurement Assistance

We procure long lead-time items like finishes, appliances, accessories, doors, and windows to minimize delays and ensure quality.

All-in-One Portal

Our Homeowner Portal lets you easily track progress, review project documentation, log issues, and communicate with our team.

Your money, well spent.

Working with Otto guarantees that your ADU will be as valuable as possible. Our units rent for more than market rate & have an outsized positive impact on property values.
