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.

I'm assuming things like taxes, permits, code, insurance etc.

On the other hand, if the renovation is a true gut with plans and permits, you will need an architect.

How do you balance the workload between seasoned agents and newcomers?

If any permits were used, check to make sure they were signed off. 

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. 

I was quoted $5,700 by licensed contractor and $3,200 by one not licensed who wouldn't pull a permit but has done several of these before.
