I am looking to put offers in an entire zip code in my area.

You need to immediately sit down a learn the Ontario codes and attend a few local LTB hearings to get a feel for how they work.

It's a revolving door,, If you choose to do this rent by the room, you will need to put a room number on each private room so if you ever have to file a eviction the room is designated,, I would suggest the electronic key pad type lock for main entry and one for each private room so easy to change codes.

Unless you are familiar with codes and the correct way to do things.  

This is a relatively new thought and I have not looked into building code and zoning restrictions that may hinder the prospect. 

It will go from looking like an old 'WOBBLY BOX' trailer to a quaint beach cottage and will mix in well with the 92024 zip code which BTW is one of the highest valued per capita zips in San Diego County.Sure it will cost me 175k plus 1k/mth to purchase, rebuild and sub lease this home but the good news is I can get about 2500/mth on it while it continues to appreciate due to is very desirable location of less than 300 feet from Beacons Beach; one of the best surf breaks on the planet.Like I said everything is relative.

Where can I find the listings of Charlotte / Mecklenberg county code enforcement violations?

Where can I find the Charlotte / Mecklenberg County Code enforcement listings. 

Put electronic locks on entry door to house, and each bedroom door. you can easily change the door codes when someone vacates..

These zip codes could offer a 9+% return on the purchase price if you buy right.
