We gave 48 hours notice at least and said it was to test the smoke detector batteries and look for any plumbing leaks.This was in a building with 26 units.  

yes I had power, a solar charger for a 12 volt car battery that I used to charge my phone and run 12 volt rv lights. 

You CAN spend even more money and get battery backup with this mode... so if the power goes out you can have a small amount of energy to run things other than the HVAC or stove... like a medical device.

Try changing the batteries

So, be quick - check the smoke detector batteries, check for leaks under the sinks, do a quick look to see if there is any mold that needs to be cleaned up, see if the toilet is running or the window a/c unit is leaking into the building, ask the tenants if there are any maintenance issues you need to address -- and get out of there.In the building I managed, we only did inspections every 6 months and did them in one morning really quickly - 26 units - bam, bam, bam.I now have to put up with quarterly inspections in the senior subsidized units I rent (have been in two so far) and it seems like every time I turn around, I've got them coming into my home again.  

Some items mentioned include: - Don't pour grease, oils, rice or pasta of any kind down the disposal because it gums up the pipes leading to a clogged sink- Do run hot water down the drain for 30 or 45 seconds after use to help clear the drain after use.I do the same with a quick explanation on how to change out smoke detector batteries (when you install the 10 year, there's no need unless it is defective) the size of the air filter and how often to change it and how to change it out, how to operate the HVAC thermostat to heat or cool the unit.

If I in fact remove that tenant's hand upon being 3 days late (with their willingly given permission).... a signed document allowing me to do so would not prevent a charge of battery levied by law enforcement.No Lease Agreement can supersede Federal or State law.

My main complaint with some section 8 tenants is they are generally a little more needy with things like changing light bulbs, batteries in smoke detectors, changing filters, and other small maintenance items. 

Bam, bam, bam, you knock on the door, check the smoke detector batteries, check for leaks under sinks, make sure the A/C isn't dripping inside, check quickly in the shower for mold, ask the tenant if there are any issues they need to report - and bam, knock on the next door.  

Leaving the place filthy and damaged.Just for the cherry on top, they stole the following items:  all the curtain rods, a bath tub fixture, and the USED AA batteries out of all the smoke detectors.
