But consumers all are on the site for free where real estate agents are constantly hawked to buy leads or participate in what is now a 35-40% referral business for unvetted leads who think they are contacting the listing agent.Their business model has always been flawed.

For the community development dept, you'll need proper plans (architect), site survey, permits, etc. when you're ready. 

is there a tool on this site? 

No, he's not an architect, he drew all designs, floor plan, site plan, etc, and we had a structural engineer design his part, and paid an architect to sign off on them.  

I dont know the delivery time on a ADU but I'd assume same with site plans and zoning. but how do you get your money out of that?

Many of the OTAs and lead gen sites, like Furnished Finder, are pushing credit card payments. 99.9% of the time I get a message from FF saying 'your tenant would prefer to pay by credit card so activate Stripe now!' 

I'm on a call now and they same decent and honest, but some reviews on here and other sites are a bit concerning.

Is there any good resource with links to the relevant sites in particular states/counties?

Best part is that it unfolds and if site prep is done, we can have a renter in in a matter of days upon delivery. 

Cleaning up our work area, I remembered what my old co-worker once told me on the construction site "There are 3 ways a job gets done: One way in our head, another way planned out, and how the job actually goes."
