Sam, I am in Mass, I am an owner /operator, I reclaim/recycle my water and I pay over minimum wage.
I am going to start of by saying the biggest problem is what rph9168 has in his signature block. "All car washes are the same, they are different." What may work for me, very well may not work for you.
As far as minimum wage, here in MA. It is currently $9.00/hour but I am starting employees at $10.50, I have to do this just to get people in the
door to work, your area may be different. To me part of the problem is not just the increasing wages but our prices. For too long wash prices have been stagnant and not increased like other industries. It seems like every few months my Dunkin Donuts coffee goes up a little bit, why are car washes so afraid to increase prices?
As far as owner/operator... I would not be able to imagine not being able to fix my wash myself, when it is down I am not making $. I would not want to be at the mercy of a repair company. I do not know anything about the laundry business but I would imagine that you have many of the same type of machines. So if one goes down it doesn't necessarily mean you are out of business, just one is out of order. In the tunnel wash business we have many items that when broken mean we are out of business until fixed, (conveyor, water pump, air compressor etc.)
You talk about automating which is great (I have both a Auto cashier and human cashier as well as prep people) but remember when your pool of employees gets smaller you have less coverage. What I mean is if you have 1 employee and he doesn't show up...what then?... If you are not there who runs the wash or who even calls for a backup employee. Or if you have 2 employees and one doesn't come in, are you going to cover? Can one employee do it???
If you are not going to be there full time, IMHO you need a manager and he is most likely going to need more than minimum wage. You will need to find that special someone who cares as much as you do about
your business.
Environmental - My experience is it is just a Phase 1 inspection that is required. If you have sewer hook up you should be fine and consider yourself lucky as long as your sewer fees are not that high. If you are forced to recycle your water, yes your water and sewer fees may be less, but reclaim is not a easy road.
Good luck - I believe the industry is strong but I don't have a crystal ball.
