Again, this depends upon your own individual usage. Generally speaking, in this area, most utilities are separate. You will have SCE for electricity, water, trash, cable or satellite, and phone. Electricity depends on usage really. It does go up in the summer drastically because of the heat. If you don't use the a/c consistently, and depending on the layout of your home (i.e.-open vaulted ceilings, open staircases, higher ceilings etc...) should run anywhere from about 100.00 up during the summer. Winter is usually significantly less. The water bill is also higher, but you can really reduce your usage by using a few simple tricks. Wash only full loads, take shorter showers, turn off the water when you're brushing your teeth or washing dishes etc... The gas bill is higher is in the winter for most homes because of heating costs...
Overall, in a 3000 sq. ft. home, I estimate I spend about an average of $175.00 per month. This averages out annually. There are some utility companies which will adjust your bill to an even payment each month if that works better for you.
Thank you for your question...
