Percentage rent is somewhat common in the US. But if I was paying $1000 already, no percentage, at least in most areas of the US. There could be some very upscale high rent areas where this would be reasonable.
Would that include utilities. Some people in some areas of the US don't realize that a tiny salon in some states pays $500 just for electricity, and they would pay $125 for the same amount of electricity in their state.
To really advise you, we would have to know what rents are. Again, some groomers don't realize that even non prime, not even close to prime, but commercial space rents for $3 a square foot per month. In fact I have some in urban cities groomers paying $10 a month per square foot, but they get top prices thankfully to make up and they work in tight quarters.
So again, it's all about what's relative for your area.
I always start with asking what are you being asked to pay, AND ONLY THEN come back with an offer to pay $XXX plus %. So percentage rent is usually a COUNTER offer to high rent areas.
