Right, the list of things to maintain and/or replace is never ending; rugs, AC filters, light bulbs, water filter in fridge, detector batteries, pest control, coffee maker, stove eyes and pans, silverware, bowls, glasses, sofa cushions, pillows, blinds, brooms, mops, vacuum, brushes, shower curtains, bath mats, beach towels. 

@Julie McCoy, @Lucas CarlI've actually been leaning towards the Smokes just because it's only 3-4 hours away from me. 

If there’s an electrical issue, it’s typically up to the landlord to fix it.Heating and Cooling Systems: The landlord is responsible for maintaining and repairing any installed heating and cooling systems.Appliances: If the property comes with appliances, the landlord is responsible for repairing them if they break down.Safety Repairs: This includes things like smoke detectors, carbon monoxide detectors, and any other safety equipment the property might have.Remember, these responsibilities can sometimes vary based on the terms of your lease agreement, so it’s always a good idea to clarify these points with your tenants.

So, they look for habitability issues as well as safety issues like detectors, handrails, GFCI outlets, etc.

After not getting responses to schedule an inspection, I smelled smoke outside the door and went in to investigate.

I used to smoke myself.

That's a smoking $p/sq ft, for CA let alone in Calabasas.

And even in areas with no fire damage, you'll almost certainly need to replace the carpet, Kilz and paint the walls as the smoke smell won't come out otherwise. 

Additionally, installing a makeup air system along with a ducted vent hood seems impractical and costly.I've considered alternative options such as a recirculating vent hood, but I'm concerned about its effectiveness in removing grease and smoke.
