However, I came across a plot right on the corner that has a 2b/1b home about 900-1000sqft(owner wasn't sure), 3 trailer plots that already have trailers on them, the renters just pay to rent the lot for $250/piece and they cover all their own amenities, and two more vacant lots that are set up with water, gas, and electric.

@Kam MillDon't know where you got your numbers, but a water heater can cost $375 for electric and $450 for gas.

Utility costs are a major consideration at -40f and -50f especially running on heating oil or wood heat (most places in Fairbanks aren't hooked up to natural gas).

We're paying $80 for yard upkeep; renter is paying garbage, gas/electric, sewer.

I count electric, gas, and water.

Worries me because you dont know if furnace goes out or runs out of oil or gas?

Here are some steps to consider when developing commercial space.Check with the city or county to determine what is required for all approvals including site plan and building permits, proffers, water/sewer tap fees, bonding requirements, inspections and CO process and time frame for all approvals.You also need to check with the utility companies and get an idea of availability and cost estimates from them for water, sewer, power, gas, cable, installation and connection requirements, tap fees, hookup charges, transformer location and relocation, power line and power pole relocation issues.Check to see if you have to install any manholes, fire hydrants, curb, gutter, sidewalks, street signs, street lighting any specific street design or access requirements,.Check DOT requirements for access, stop lights and permits, traffic studiesDWQ requirements for permits, permit fees, time framesThis is a broad overview of the process and your civil engineer can handle all of this but it's good for you to know exactly what's required.

Usually it is a tenant that gets a bit of a discount and can be assigned the title, along with other basic menial tasks(meeting inspectors, reporting issues to you, sweeping up messes, etc,), so when and if the city comes a knocking, you have someone there with that title.Also, good for someone to know about the hot water heater, electrical panels, gas shut off valve, water shut off valve, etc.To your broader question of "needing one?"

Electric, gas, water, and trash are common items that can be passed on to tenants, depends on the area.

Bonus things I provide are a smart TV, gas or charcoal grill, sundries, garden hose, vacuum cleaner, and bedrooms decorated as if Hugh Hefner himself was going to stay there.
