Cost of a one room office, guest house, laundry room (that is an absolute work horse of a building!)

The backyard accessory dwelling

Travis and Kelly approached New Avenue to discuss adding a multipurpose casita/office/guest room/laundry room in the backyard of their Oakland, CA home. We created a 250 square foot casita that is an absolute workhorse.  Any given day this casita serves three or more purposes: Pet-sitters, house-sitters, house guests, laundry, office, and au-pair quarters.

Construction time was 6 months. When you include custom design, permits, survey, engineering, tree removal, site work, utility upgrades (and finally actually building it) the cost is $116,700.   The full detailed budget is here: 250 Square Foot Cottage Completed Budget

Project like this take 6 months to design, 6 months to permit and 5 months to build.  That is almost 18 months.  You can read more about it here: Average Project Timeline

Some challenges to this project included poor access to the backyard that required hand carrying everything in and out, a sloped lot with drops from the neighbors yard, and older utility lines that needed replacing.

Just as the the work came to completion Travis and Kelly adopted a baby. Now they take turns working from home two days a week in their backyard office so they can spend quality time with the newest member of their family.

When family and friends are in town to see the new baby or if Travis and Kelly are entertaining and hosting a get-together, they offer their casita as a small home away from home for overnight guests. It has a fully functioning bathroom and working washer dryer. In the instances the family is away, it serves as a residence for their dog-sitter.
