You are way too late to the party and power in Southern California is too expensive (and going up next year thanks to our Governor Jerry Brown). I wouldn't recommend purchasing any hardware to do mining but if you have PCs with decent video cards you can download nicehash and mine when they are idle. Nicehash mines other crytpo currencies and sell them automatically to give you bitcoin. With a GTX 970 and a 1080 Ti I have made about $90 in 3 months with only a few dollars increase to my power bill.
Buying an Asic is a risk no matter what you are mining. The thing is that the market moves so quickly, your asic might only have a few months of mining potential before the difficulty factor is ramped up again due to new better Asics on the market. Then you are left with hardware that really cannot do anything of value.... it isn't worth even pennies. So it becomes a gamble. Are the Asics you plan on buying going to pay for themselves before they are obsolete?
