However, we (my parents and I are the owners) noticed that they are using the HVAC in excess and using what appears to be unnecessary electric (TVs and lights remain on even when not in use and air conditioner is running constantly).

As mentioned above, though, you could see delays in inspectors coming out to approve/deny draws...but more than 1-2 weeks is quite excessive.

(Additionally, Case law has allowed the inclusion of water charges when calculating monthly rent when paid by tenant with rent)Section 5321.16 | Procedures for security deposits.Ohio Revised Code/Title 53 Real Property/Chapter 5321 Landlords And Tenants(A) Any security deposit in excess of fifty dollars or one month's periodic rent, whichever is greater, shall bear interest on the excess at the rate of five per cent per annum if the tenant remains in possession of the premises for six months or more, and shall be computed and paid annually by the landlord to the tenant.https://codes.ohio.gov/ohio-re...This is why we (and all the other landlords I know) quit doing pet deposits and started doing 'non-refundable pet fees' 

@Michael Lutes,The short answer is this:[1] In the RM-1 district, the minimum lot area required per dwelling unit is as follows, provided that, whenever the calculation of permitted number of dwelling units results in a fraction of a dwelling unit, then the number of permitted dwelling units shall be rounded down to the nearest whole number: 325(.a) A minimum 360 sq. ft. of lot area is required per dwelling unit for the first 1,440 sq. ft. of lot area.(.b) A minimum of 480 sq. ft. of lot area is required per dwelling unit for the lot area in excess of 1,440 sq. ft.; provided that, if the green roof conditions set forth at § 14-602(7) are met, the number of units allowed is 25% greater than indicated by the foregoing lot size requirements, applied prior to the inclusion of any other applicable increases in allowable units.Click the link below for zoning use chart: (Table 14-602-1.A)https://codelibrary.amlegal.com/codes/philadelphia/latest/philadelphia_pa/0-0-0-154712#rid-0-0-0-170236You also have to check if you are located in an overlay district.

Hi Guys,Having several properties divided into several LLCs.. these LLCs are owned by a Parent LLC, which is owned by a partnership.LLLP -> Holding LLC-> Rental LLC1/ LLC2 / LLC3All income/expenses are flowing out/in from a single bank account.im using QB to account and allocate by classes, so no mess there.i heard there is a need to have a bank account separate for each LLC, it seems excessive and cumbersome to me.is there a better way to go about this and maintain a balance between protection and ease of operating?

I would investigate to see if the renters are using excess water, most commonly caused by a running toilet. 

Find out later that is a "Private" hydrant forthe Apartment complex you bought the excess land from.

Does your lease have any provisions about excessive water usage or leak reporting requirements?  

Example, they left a couch behind that cost you $600 to remove/excessive personal items that required you to "hire a cleaning crew/movers" - things like that... then you handle that issue on your own, charge the tenant out of the security deposit for it and use the funds as needed.
