Install central air and the next thing this guy is likely to complain about is his high electric bill.Keep in mind that in many states a landlord must provide reliable and working plumbing, electrical and heat. 

Can someone guide me where to apply and obtain a license to build this basement unit to an official unit with its address, electric, and other amenities?

Hello All, i came across this college town property - it is a value add opportunity. 14 Unit Complex - 12 2bed/1bath & 2 1bed/1bath * Separate electric and water meters.

As well those government guaranteed section 8 rents have been consistently increasing every year. 5 Bedrooms are now renting for $2000 plus tenants pay ALL utilities. 3 Bedroom Duplexes are up to $1650 x 2 a month = $3,300 + they pay gas and electric.

It has separately metered electric service. 

Older buildings with older systems: plumbing, electric, HVAC, roof, tend to have more maintenance costs than newer properties.  

Rick, I think online permits are limited to the items below that I pulled off the website: Request Electrical & Plumbing permit for new or replacement electrical & plumbing for single family/duplex homes

Units are metered separately for gas and electric.

I did everything myself from cabinetry, drywall, flooring, windows, plumbing electrical, etc...

Mainly because I "assumed" how long could utilities such as water ,trash and electric really get backed up without getting shut off.
