You want smallish, well soundproofed rooms so your tenants aren't disturbed by others. 

Another problem with people living closer together is noise disturbance. 

Originally posted by Mike Cartmell: Preliminary/Final Drainage Report, Erosion Control & Grading Plan, Water Report, Traffic Study and an Erosion Control Permit will be required if the area of disturbance is greater than 1 acre, which @J Scott mentioned.In Maryland, it's not even 1 acre...it's 5000 square feet!

Playing music late at night to disturb is against the law.

And, disturbingly, true.

Also, bear in mind that tenant-occupied properties can be challenging and listing agents often don’t want to disturb tenants unnecessarily which is why the reason for !

Called the landlord reference (provided by the tenant) and the landlord stated that they were currently being evicted, late on rent for the last few months, and have caused disturbances within the complex.  

If nothing else, it would show the tenant you are taking their concerns seriously.I would also do a search on the property history;   it's very possible the tenants did this as well, and uncovered something disturbing about the house that is the root of this.  

Hello GeorgeI wish I could see your project to give you a better idea,,,plumbing jobs are like people ,,,no 2 are alike,,,Moving or disturbing original drains and water lines can be tricky,you must proceed with caution like a surgery,,,,no place for amateursYou also want to consult an experienced tilesetter for the creation or altering of a shower pan,,,,they must be perfect and sound,,,,If your going to go that far I strongly suggest upgrading to a Moen shower valve with integral shutoffsI would consult a family owned plumbing company with good refferals from a local supply house.Having said that ,msot of these folks want to supply there own materials and do a "turn key " installation.Interview them on the phone and have them over to give you na accurate price quote for the comp[lete job.This way you both know how long and how much.It also gives you a chance to say yes or no ,,,yay or nay.This is how I conduct my business and I havent found a better way.Everyones on the same page,,,,Hope that helpsDD

I myself have considered carrying a sign at one of those "free" seminars but I do not want to be arrested for "disturbing the peace".
