*Approximately $200K for a restroom building in a public park.
No, because of the publicity surrounding the $1.7 million original estimate a private party donated $425,000. You can't seriously expect that as a matter of routine.
To show you how out of touch you and California are, I am a private lender in Ohio in addition to being a lawyer. Recently several investors have presented several very beat up 4000 sq ft mult-family structures that they could buy for $150,000 -- $175,000 and fix for under $200,000. Depending on the configuration of the bldgs they could rent typically for $1,000 a month for 4 units. Myself and another lender will provide the money. Basically 4 families will live in what will be nice buildings for less than it costs to build a toilet in Calif. You might be insensitive to the cost and waste in California because you are a member of a privileged class as a professor and other professors and graduates of the UC system benefit by being hired to write up useless multiple reports (for instance environmental reports) as a precondition to build a toilet or restroom building as you call it. (According to chat gpt building was 50 sq ft when completed. $12,500 per sq ft. as I analyze it. $4167 per sq ft as you analyze it.
Something you and all Californians can be proud of,
