THIMBY designed and is building a tiny house that is ecologically sustainable.

Tiny House in My Backyard (THIMBY) is a project of Sustainable Housing at California (SHAC), an interdisciplinary group of students at the University of California, Berkeley. Construction is underway—right now, the THIMBY team is building a 240 square foot tiny house on wheels. They are looking for a City of Richmond homeowner to host this THIMBY house in their backyard upon its completion later this year.

The City of Richmond, California, recently renewed an ordinance (No. 07-21 N.S.) creating a pilot project allowing tiny houses on wheels to serve as accessory dwelling units (ADUs). These units will help alleviate the shortage of affordable housing available to low- and middle-income households, as well as working, formerly homeless individuals and small families in search of permanent housing. THIMBY partnered with nonprofits Tentmakers, Inc. and Care Association to complete construction of a “park model” tiny house on wheels and is seeking homeowners who may be interested in hosting the dwelling in their yard.
