New program helps bring tiny house dreams to life in SLO city backyards

Smart Share Housing Solution's newest program is ADU SLO, created to make connections between people and tiny house living. A new ordinance now allows Tiny Houses On Wheels (THOWs) in SLO City and Arroyo Grande backyards, opening up new housing possibilities. (For now only these two cities allow ADU/THOWs.)
We're here to help folks go from dream to reality, whether they have a lot that might be suitable, or own their own tiny house and are looking for a yard to host it.
The photo shows the first yardshare match in SLO! Rita and Taylor agreed to share Taylor's yard and Rita moved her tiny house in on August 13th. Congrats to both!
Our staff has background in planning, permitting and construction, and experience in drafting sharing agreements. Sign up below to stay in the loop, or email us at info@smartsharehousingsolutions.org

Our Goal: To help the community move forward with this new opportunity and get Tiny Homes On Wheels, and other Accessory Dwelling Units, in SLO backyards as housing for low income SLO residents
