No, you don’t. Cottage can help you through each stage of the ADU journey, but you don’t have to commit to everything up front. You can move as fast as you want and pay as you go.
Yes, you can. However, if you choose a Cottage builder, you’ll also receive support from our team throughout construction to get your project across the finish line on time and on budget.
We’re currently serving the San Francisco Bay Area, Los Angeles, San Diego, and Seattle. See the municipalities we work in here.
The cost of an ADU depends on the size of your project, your site conditions, location, and design. Through Cottage, you’ll receive multiple competing bids for your ADU build, ensuring that you get competitive pricing. Book a consultation with us today to get tailored budget guidance for your project.
Free feasibility research: We assess your property up-front, at no cost to you to avoid surprises.
Efficient design: We design for elegance and efficiency to keep build costs down.
Competitive pricing from consultants: We’ve negotiated exclusive pricing that you can’t find elsewhere.
Multiple competitive bids: You’ll receive multiple line-item bids from vetted contractors. Competing bids mean you’re getting fair pricing.
Our vetting process includes an interview, site walk, reference checks, and bid reviews. Of hundreds of contractor applicants, we’ve accepted just 5% that meet our standards in quality, service, and value.
