Their base install ran $375 as I was allowed to wire all the EXIT signs, emergency lighting & hard wired smoke/CO detectors.Materials ran about $4,500 as I was able to use 3/4 Pex, but it took 18 long months of meticulous nook & cranny routing, sprinkler head installations & code inspections.

I don't know what the process would be like to turn an existing structure into a boarding house--but I'd imagine, your larger problem would be with existing zoning, which likely would not permit a boarding/rooming house in a zone where you currently have a single family home.The state maintains information about rooming and boarding houses here: https://www.state.nj.us/dca/divisions/codes/offices/roomingboarding.html but your municipality will have its own zoning laws about what is permissible.

so when a new property comes on the market i can look up the zip and address and know 1) have i ever reviewed this property before and if so what has changed, 2) i have detailed comps for the zip code.
