Transparent Process

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

Exclusive Bids

We obtain exclusive bids from our vetted contractor network and select the best one for your new ADU.

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.
