Project Cost:

Goal: The homeowner wanted to add a detached ADU wrapping around the existing primary dwelling and spanning from the front yard setback to the rear yard.

Design Challenge: The ADU was visible in the front which required additional design specifications to meet the zoning ordinance. Because the newly constructed ADU would be attached to the primary dwelling, the city required a design with a higher fire rating.

Process and Solution: The Homeowner had a fully realized design which matched the primary home in style with a footprint of 67’x17’. They wanted a modern shed roof with clerestory windows to maximize light and privacy.

The final ADU included three bedrooms, one with a master-bathroom and bathtub, a second bathroom with a shower with a standing washer-dryer set, and a full kitchen/living area.

This project was completed in 5 months for $225,000, including Housable's feasibility and drafting services. This project was completed quickly because the homeowner managed the project, interacted with the city, and was very active and decisive during the process.

Unique Project Traits:

  • This large ADU was visible from the front and required additional design specifications.

  • Housable verified that an existing sunroom was permitted as well as the location of lateral sewer lines and the need to upgrade electrical service

Using this model as the starting point, this project was customized to the owner's preferences and the conditions of the property.
