No matter where you live, whether its San Francisco, Alameda, or Berkeley, one code requirement remains the same. Smoke detectors are required inside and outside of each bedroom. Its not that the building inspectors really want to checkout your whole house, it is a safety precaution. Even if you are "just remodeling a kitchen or small bathroom" it is something that all building departments are responsible for. Its a good thing, big brother is actually looking out for your best interest for a change. Does this mean that you need to re-wire your entire house to put in a fancy hardwired system that alerts the fire department? In most cases, no. Requirements of that kind are usually reserved for new construction or when a certain percentage of your home is being worked on.
So what are your options? You could run to the hardware store and purchase the lowest costing model off the shelf, or you could go to the Mac Store and drool over the Apple computers and iStuff to buy a Nest model with its sleek design. The drawback to the Nest is that it is now a Google owned company and they have been able to turn its sensing features into more personal anylitics for their marketing strategies. I have done some research recently because my Apple employed clients are anti-Google-tracking, especially when it comes to your coming and going in your home just because you wake in the night to use the toilet.
You may be aware of the concerns about carbon monoxide during sleeping hours too. This is because its presence will actually cause drowsiness and if you are already asleep you are not very likely to notice any difference in your ability to take in the required oxygen to continue to breath. So how can you keep your newly remodeled home less cluttered without sacrificing your safety? First Alert has a wonderful, clean and simple combination detector that is photo sensitive to detecting smoke and has an active voice. Its the PC900V, it will tell you which alarm is going off with words, it will also tell you when its battery is getting low so that you don't end up taking it down in the middle of the night and never returning it to its post. Its affordable too, you can buy it directly from their website or in most local hardware stores like Ace.
Now you can sleep safely in style without the concerns of the big G knowing even more about your hourly habits. Nighty night!
