For instance, changing the battery in a garage remote and reprogramming it.

I don't really want a separate meter for the ADU, especially since we will have solar/battery installed on the main home and would want the benefit of that for the ADU.

This presence alone has drawn other logistics and distribution companies to set up shop in the area, solidifying Louisville’s reputation as a key logistics center in the U.S.Moreover, the automotive industry is making waves with Ford’s massive investment in the BlueOval SK Battery Park in nearby Glendale, Kentucky.

Not to mention I ditched my iPhone 5S for the Samsung Galaxy Note 4 (battery life = sooooo much better, lasted TWO DAYS without charging) and I don't have iTunes on it (and I probably won't install it either). 

@Yousuf Kaleem Change the batteries in the smoke detectors.

Smoke detectors, missing batteries 6.

how long do batteries last? 

I was wondering if Section 8 will accept battery operated light fixture as permanent light fixture.

You'll also need storage space for cleaning supplies, change of linens and towels and small miscellaneous items like a first aid kit, extra batteries, flashlights, broom, vacuum, etc.
