Hi, I was visited by an inspector from the Department of Licensing in Seattle last year. My business is in my home and there were 2 things I needed to do - one was to out up a little sign that she provided with the words, "not for public use" on the sink I use to wash supplies and secondly, I did not have my bold spill baggie double bagged with 2 pairs of disposable gloves. She came unannounced and passed me with flying colors. they get around to all spas! salons and home based businesses every other year or so.
