I live in SW Petaluma, next to what used to be the Hash Ranch. This 16 acre parcel was once proposed for a dozen very large tract homes, but didn't fly (the developer tried to claim it didn't violate the the City's prohibition on ridgetop development despite the project being called "Pinnacle Ridge".) It looks like it has been sold (again), aimed at a single family "estate" dwelling. I wonder what might be the viability of a "tiny home co-housing village". It may be too late; it just sold. But it would be nice if it could accommodate more than just one family.

Aggregated communities can also consist of 1000-1200 square-foot homes. Such communities should be designed with a small community center, including a communal kitchen, dining room, and rooms for residents’ visiting family to sleep.

And yes, yes to tent, cabin, travel trailer, and mobile home communities, also including such a community center. Living outdoors is an ancient way of life and continues around the world. Why not make that available here?

Find a way to remove the stigma associated with tiny houses.

For the rewording you can include form-based codes (https://formbasedcodes.org/definition/) and more diversity of housing due to zoning changes. Converting single-family homes to duplexes, triplexes, and quadplexes. Sonoma County has many large single-family lots. ADU's, JDU's, and various conversions of existing buildings as others have mentioned should also be included as should community land trusts.

Tiny homes are a useful band aid. The larger, painfully obvious solution to our housing shortage is to acknowledge that we don't have a housing shortage, we have an equity shortage. Sonoma County has 19K habitable but unoccupied housing units, 10% of our housing stock. We have 3K people experiencing homelessness. Why then does our conversation about housing focus on building more, instead of encouraging owners of unoccupied housing to use some of the housing sitting vacant? Because people who own second and third homes have far more political sway than those who have none. A vacancy tax on unoccupied housing units would encourage occupancy while also funding efforts to improve and add affordable housing. I ask everyone to consider whether the multiple home owners would suffer more from a vacancy tax than our unhoused neighbors do camping outside those increasingly vacant neighborhoods.
