And when I applied for a rental license it was a really easy process, they cared more about the safety things like having enough smoke detectors and fire extinguisher and GFCI outlets near water, etc. 

Most utility water meters have a small red or black dial on the face of them that is a leak detector.

The laws on smoke/CO2 detectors aren't going to get more lenient as time goes on.

Things like leaking pipe under sink, downspout that needs securing, sewer vent pipe out to the attic, missing smoke detectors in a unit, loose material, etc. are all very easy fixes that we would be happy to make for you. 

The 4th Thursday of every month is a standing inspection for fire prevention to check all smoke detectors and CO detectors.

So they are financially misaligned on long-term performance (and I think this is why there are so many people who have had bad turnkey experiences) And, as someone who has done lots of rehabs directly myself, I have seen hundreds of ways that turnkey operator could take shortcuts (to the detriment of the investor but beneficial to their bottom line) which investor could never detect (or not until years later when it's too late).

How about motion sensors on a long driveway with a chime in the house? 

The time constraint really is not that bad once you have everything in motion.

The homes had no working smoke detectors (Huge liability in CAlifornia), he was under valuing the rent by over $300 on 2 of the properties, and the lease was a 1/2 page long with no rules for the tenant to follow.  

This will be a detailed inspection of every room, ceiling, floor, plumbing, smoke/CO2 detectors, window treatments and screens, etc.
