All you need is a hoodie and a screwdriver.Constant motion alerts give no real value - easily and often ignored. 

Hey Cole,Definitely check out the Charlotte Uniformed Development Ordinance.

(Rooming and Boarding House Act of 1979), violations of the Newark MunicipalCode, and violations of the Uniform Fire Code.

If I have to replace a few, I sort of feel like replacing all might be the way to go so there is uniformity. 

We have the Uniform Commercial Code, these generally cover dealings in personal property sales and leasing, business contracts, installment sales, banking, negotiable paper and notes, investment securities and secured transactions.

I added a motion sensor light on the front and rear of the building; trimmed tree branches at least 10 feet off the ground.

But that's all Brownian Motion.

Change to automatic garage doors, and motion lights outside.

Turn key is like buying a house someone flipped, you pay top market, and often is substandard quality. you are much better off buying a marginal deal that needs a rehab, and managing the rehab, at least then you have control of the quality you decide to use, and if you scale you can create uniformity to your portfolio.   

Always enforce the rules uniformly unless you want to risk a discrimination claim.
