We're a team of architects, builders, and technologists committed to solving housing affordability by making it easy to build an ADU.

About Us | Cottage

We empower homeowners and contractors to build more and build better.

Our mission

About Cottage

Room for more

We are owner-builders. We roll up our sleeves together, do whatever is required for our homeowners and partners, and do it right.

Build like you own the place

In an opaque industry, we build trust with radical transparency. We offer this transparency to and ask for it equally from our homeowners, partners, and team.

Transparency

We're taking an entirely new approach to an age-old industry. We aren't afraid to pave the path forward.

Break ground

We started this business because we felt the pain firsthand and knew there had to be a better way. We obsess over the homeowner and partner experience and build products/services that solve their most acute pain points.

Customer obsession

Design and Build Your Custom ADU With Cottage

Yes! New California state regulations mean nearly all residential properties (both single family and multifamily) are eligible for ADUs. Additionally, municipalities must allow all ADUs of up to 800 sq. ft. in size with 4 ft. property line setbacks and up to 16 ft. in height under the new California Statewide Exemption ADU rules. Most municipalities allow larger ADUs with even fewer restrictions, and these vary from city to city. We cover this topic in more detail in our <a href='/resources/2021-05-05-is-my-property-eligible-for-an-adu/'>Resources page about ADU eligibility</a> and in <a href='/regulation/'>our municipal ADU regulations pages</a>.

Is my property eligible for an ADU?

Accessory Dwelling Units can come in many shapes and sizes, from an attached garage conversion or an in-law suite to a backyard guest house or a basement studio apartment. The best ADU design is one that matches the use cases, budget, and needs of both you and your property. Cottage’s architectural design team can help bring the best ADU for you to life. Learn more from our <a href='/resources/2021-05-19-how-do-i-choose-the-right-adu-floor-plan/'>article describing how we think about floor plans</a> and to see a few sample ADU designs.

How do I choose the right ADU design?

Cottage’s in-house design team specializes in only ADUs, creating efficient and elegant small space designs that result in a smoother permitting process. After the initial permit submission to the local municipality, our permit operations team works hand-in-hand with our design team to address plan check comments promptly while keeping you in the loop. Cottage has built local permitting expertise in over 50 municipalities - we’ve likely permitted an ADU in your city already!

How does Cottage permit its ADUs quickly?

Cottage’s ADU builder partners are local construction experts that specialize in ADUs and have decades of experience building in your area. Cottage carefully vets all potential contractors to ensure that they not only do high-quality work, but also deliver projects at great, consistent prices.
