The inspection will fail for serious items like dead battery in a smoke detector or trivial items like missing 1 screw on a outlet or switch cover plate.Faill the inspection and they will advise the tenant to move out!

My real estate agent who uses zipLogix rental lease is trying to convince me that I HAVE to use the dual powered (AC and battery) smoke detector.The lease is referring to § 9-102.

As for smoke alarms, be sure to look at the fine print, many municipalities require hard wired smoke detectors in every room so it's not as easy as getting battery operated ones.

He install smoke alarms connected to batteries because he doesn't trust his own electrician.

Tech support had me remove the battery for the third time in 32 days.

In batteries that energy is stored in some form of chemical reaction, that then reverses to release the energy.

Your time is too valuable looking for the next deal or improving systems to be changing batteries in a smoke alarm or unclogging a disposal.

Maintenance to some degree is allowable as well, be reasonable, a tenant can't be expected to tow a car to have the battery charged!

Also, grid-independent systems are a lot more expensive because you need to add battery storage.

Otherwise I have to have a smart phone or ipad and hope that it's getting a signal or not battery challenged.
