ADU SLO, a program of the non-profit Smart Share Housing Solutions, was created to help push opportunities for safe and affordable housing through Tiny House On Wheels (THOWs) and Accessory Dwelling Units (ADUs).  

What is an ADU? Accessory Dwelling Unit (ADU) is a permanent residential dwelling unit providing complete independent living facilities for one or more persons, and is accessory to an existing or proposed primary dwelling. Started in 2019, The ADU SLO Program assists property owners on the logistics of adding housing units using backyards, garages, infill lots and existing buildings that already have infrastructure and embedded energy grid. In mid 2019, the ADU SLO held the Tiny Footprint Expo, showcasing small homes and offering educational workshops. 850 persons attended more than 25 educational workshops and more than 6,000 people attended the 3-day event!

This project is funded for 2023 and 2024 for How-To Workshops and a Demonstration ADU project in the City of Arroyo Grande. (At this time, site feasibility visits and ADU information services will be limited to Arroyo Grande residents.) Please look for announcements and updates on upcoming workshops-and you can find updates on the City of Arroyo Grande's pre-reviewed ADU plans here: City of ArroyoGrande-ADUs.

The Demo Off-Grid Caretakers Cottage is here! A big "Thank You" to our project partners, the SLO Guild Hall, for allowing use of their beautiful grove to showcase the home. This unit shows how a small living space can function as a safe, efficient and beautiful living environment for the County's 1 in 4 single person households, including SLO's single seniors... Smart Share Housing Solutions will hold workshops, coffee chats and other educational opportunities at this Demo House in the Grove behind the SLO Guild Hall. Stay tuned for more info. The Demo House will:

  1. Show off a similar beautiful interior layout as homes proposed for the Waterman Village
  2. Help Smart Share Housing Solutions establish a pilot program in the County allowing 5-15 caretakers quarters, off-grid THOWs, on multiple sites at churches and service clubs
  3. To hold energy efficiency workshops in conjunction with and other partner organizations
