See if that property management company is keeping up to date on the latest laws (for instance, look to see if a newer lease still requires the tenant to replace batteries in smoke detectors -- it's now the California Landlord's responsibility).  

They beep when the battery is about to die or when kitchen fumes are abundant.

I have found that the cheap, battery powered fake cameras with the flashing red lights are a great deterrent.

I would never rent out a house with at least battery powered smoke alarms and a CO monitor.

Hi @Matt Ryan  I usually have a little useful welcome gift to new renters.... either some smoke detector batteries and a couple light bulbs, or a few cleaning supplies. 

Its important to flush the drain every few yearsReplaced sump with twin pump system and battery backup with alarmTied stairwell drains to drain / sump systemInstalled dimpled membrane on wall that will divert any wall seepage to drain/sump systemDug out / cleaned window wells 3ft down and re-graveledAdded proper exterior grading, swale system downspouts and french drains

But there is no way to avoid it - the tenant complained to the building department, and the building department says we MUST install an owner's meter, rather than simply changing the bulb over to a motion detector battery operated light.

You haven't witnessed this person smoke inside, so why not find a reason to go over there (maybe to change the smoke detectors/batteries) and check if the whole home reeks of smoke.

The City fire marshal has an annual inspection where we load new batteries in the CO/Smoke detectors and replace the fire extinguishers.  

Used batteries and used motor oil are contaminants in CA and require special disposal fees.
