Questions?

What types of projects are you able to take on?

Cottage’s network and platform are currently best fit for major renovation and new construction projects that involve multiple pros, typically above $50,000 in construction cost.

Who handles permitting and coordinates with the city?

Most designers and architects will include permitting in their services. If you need engineers or other consultants, Cottage’s platform allows you to request proposals at the click of a button.

What is Cottage’s role after I start working with a pro from your network?

The average new construction project involves 6+ different specialized pros. Our platform helps you easily hire other vetted pros and allows them to collaborate on a centralized source of truth. We also have a dedicated customer success team offering on-demand platform support to ensure you have the best experience possible.

In which areas do you have coverage?

Cottage’s network currently spans across the San Francisco Bay Area, Southern California, and the Seattle Metro Area. We do offer remote designer options for homeowners that don’t live in our service areas.

Does my property qualify for an ADU?

California’s statewide regulations make the vast majority of residential properties eligible for an ADU. Washington’s regulations tend to differ by city so we recommend consulting an expert designer in our network. Learn more in our article about ADU feasibility.

How long does the process take from start to finish?

Timelines vary by project and depend on your project type, complexity and design. Book a call to get guidance on your project timeline from a Cottage expert.

How much will my ADU cost?

Learn more in our article about construction costs, or get an estimate for your property here.

Design and build with confidence.
