Available to City of Arroyo Grande Homeowners

Smart Share Housing Solutions is pleased to kick of its Arroyo Grande–ADU AND THOW program in May 2023. Smart Share has an American Rescue Plan Act (ARPA) grant from the City of Arroyo Grande to enhance affordable accessory dwelling unit production in the City. The program aims to: 1) assist lower-income homeowners to produce ADUs; and 2) to create lower cost ADUs that can be rented to lower income residents or family members for affordable rents.

This project is funded for 2023 and 2024 for five (5) FREE "How-To-ADU" Workshops and a Demonstration ADU project in the City of Arroyo Grande. Site feasibility visits and ADU information services will be limited to City of Arroyo Grande homeowners only.


For A.G. homeowners looking for help with community housing needs, create inter-generational housing, and/or earn a bit of additional income, ADUs and THOWs can serve all these purposes and more!

Movable tiny houses are typically separate, independent living quarters with the following characteristics:

  • No larger than 400 square feet
  • Mounted on a wheeled trailer frame
  • Includes basic functional areas that support normal daily routines, including a bathroom, kitchen, and sleeping area
  • Designed and built to look like a conventional single-family house
  • Utilizes conventional building materials
