The garden unit is non-conforming but fully equipped with 3 bedrooms, a living room, and a full bathroom.

Put locks on each bedroom door so individual tenants have security of their personal belongings.You need a really good set of rules regarding shared common space, cleaning, kitchen use, bathroom use, etc.Be very clear about the rules up front, and selective about who you put in there.

None on ceiling, walls, bathroom, etc.

Hi everyone, I recently purchased a house and have no idea how I renovate this bathroom.

Turns out the daughter's boyfriend was smoking in the bathroom...Sometimes they can scrub, others it has to go down to the studs and rebuilt if there's been a lab.

But Now, in my area, not only does a plumber have to be the one that touches that, but I am "supposed" to hire a plumber just to demo (i.e. remove a toilet or vanity) the house. 

Because of their experience, I was able to get parts of the work covered under code upgrades for things that I did not build back exactly as they were before the claim (e.g. moving plumbing to expand a bathroom).At the end of the day, no one is going to care more about your property than you.

Complicated rooflines, modern details that require a bunch of steel framing, excessively large great rooms, spa-like bathrooms, etc would push you into the $1,000-2,000 range.  

We painted, replaced flooring, added countertops, fixtures, and bathroom finishes.

The 1 bathroom has the major leak at the toilet which is causing major damage under the floor.
