I bought a commercial house, but I live in ordinary residents, which is equivalent to civil use. Is it reasonable to collect property fees and utilities according to commercial purposes?

Reasonable. Because the certificate you applied for at that time was for commercial and residential use. Go home and look at your real estate license. Commercial and residential buildings can be used for business and life. Rent if you want, and give full play to the biggest advantage of this kind of house. If you and many owners think it is unreasonable, you can negotiate with the property.
