"Good Housekeeping"
E-911 Addressing:
Your address numbers should be posted and visible from the road so that emergency service agencies can easily find you in case of an emergency. Posted numbers should be a minimum of three inches (3") in height.
Air Filters:
Change your air filter as much as you need or would like to, but a good practice is every 1-2 months.
Smoke/Carbon Monoxide Detectors:
Change the batteries in these life-saving tools at least every six months.
