Legal Aid of Sonoma County – Lead on multiple campaigns for rental housing registries. 

• North Bay Organizing Project / Sonoma County Tenants Union – Active in efforts to get a rental registry in Petaluma. Organizes political support among renters.

• Sonoma County Community Development Commission – County agency that runs many social programs targeted at tenants, including the County’s Housing Authority. A major utilizer of rental registry data. Possibly the department running the registry. Permit Sonoma is the other candidate.

• 3Di – A company that operates several rental registries around the state, including in San Francisco, Oakland, and unincorporated LA County. 3Di has given a quote to Sonoma County for a rental registry, putting the estimated cost at less than $5 per rental unit per year. 3Di can explain rental registries and offer models that already work.
