If not if you have site control you can look at other permits for construction in the area for other projects.

Now I have only logged a few Redwood sites in CA. ( too tough to get permits) and what they allow you to harvest is younger trees as you note.. 

Best to partner with a builder who has experience in JC and can navigate the permit/zoning process with the town plus do the renovation work needed.

All-in costs, including design, survey, permitting, construction loan interest, land, construction will be $360,000.

My brother's rental is a little over 1,000s sqft heated living area, so the ADU would only be permitted for 500 sqft in Winston-Salem, according to information I found online .One advantage of an ADU I believe would be the ability to hook up to the primary residence's utilities.
