Thanks for backing my post up.
He holds services three times per week... in a building permitted only for residential use. This is an issue of safety and 67 code violations.
If he wants a church, get the permits and build a church. If a pastor is holding service in a 2000 square foot building because he can't fit the people in his living room... that's a church.
If there was a fire and people died, people could have sued the city for knowingly allowing this to continue.
