Reinforces the thought that the innkeeper should always be on top of a few things:
Ensuring smoke detectors, CO detectors are present and the batteries/power supply are always proper.
Proper fire extinguishers in each unit and in the kitchen
Keeping the fire and emergency numbers in obvious places in each room
Getting fire inspection if possible, by the local professionals (if they are willing to do this).
Ensure electrical system and "fuse box" are modern, ample and correct. The property inspection we just had, the guy said the fuse box was unbalanced. And not a small thing with every room having electric baseboard heat. Older homes often have insufficient wiring. Simple things like replacing all bulbs with CF/LED, avoiding electric baseboard heat, helps keep the wires cooler.
Keeping grilling activities away from house. Insurance companies (rental properties) always ask me about 4 things - is grilling allowed on decks? Pools? Trampolines? Dogs?
