I am thinking about building a large woodworking shop and Sandy City kept emphasizing that "you can't have anyone sleeping in it". 

How many other heirs could come out of the woodwork? 

It's most common on windows, doors, stairs and other painted woodwork - but could be in lots of other placesI believe the EPA website has some info on how to encapsulate existing LBP - or you could just paint the place.

REI instructors "gurus" are coming out of the woodwork. 

You can give it as a percentage if you're afraid the relatives will come out of the wood work now that you're rich.

Have you folks ever heard of an aggressive bidder buying rights of redemption for a given property prior to an auction, then coming out of the woodwork after the sale to demand a huge fee to sell those rights to the high bidder?

The sellers don't want me listing them on the regular MLS because they say they don't want the "vultures" coming out of the woodwork and lowballing them (although the price I got them to agree to was within the market ranges for their respective areas).

I also go ahead and install curtain rods because I don't want a lot of holes in my woodwork.

I will say that I have a separate business checking/saving account that I opened several years ago for a woodworking business that operates under the same sole proprietorship business name.  

Expect the tar from the nicotine to penetrate into the HVAC system, electrical outlets and smoke detectors, seep into the walls and woodwork, seep into floor coverings and window coverings, and seep into cabinets.
