I found out the hard way that is typical in the area to go renting as a single mother and a week later the boyfriend moves in, or the alcoholic mother,or the date all men in the neighborhood sister...and it could go on and on.Will update after my talk with PD.Again thanks to all who helped

It just has to be enough time consumption that you can actually build a process/SOP around it. 

But I REALLY want to cut down on water consumption since I pay the bill.

The natural / nature made version noone has ever overdosed on it or died from it(marijuana alone that is - if its mixed with other drugs/alcohol those are the disruptive toxins that can kill...) however this gets a thumbs down.  

It's just one more thing to worry about besides alcohol and other drugs to monitor.

As a direct spray I do like using rubbing alcohol ( high alcohol content) in a spray bottle , a little more natural  and tolerant then store sprays 

I would definitely have a "no parties" policy, because alcohol and lots of people is a recipe for disaster.

I am interested in accepting VASH vouchers for homeless veterans in Detroit and since it tends to have a high rate of single males especially  alot of drug/alcohol abuse in this market.

Guests wont appreciate loud noises, parties, alcohol, etc....

Sub-metering can be a cheap way of allocating costs to each unit, but you usually have to leave the master meter (the city's meter) in your name, making you responsible for the water consumption.
