In the early 80s the lone building inspector in Piedmont asked me to apply for an open position on the Design Review board because he didn't want a "housewife" on the panel, after several months I resigned because I couldn't bear sitting on a panel debating until midnight which color we were going to mandate a home be painted. In Pleasanton several years ago they mandated a La Habra stucco color on a home, in the end the owner changed the color
by one shade, the building department refused to final the home because of the color change, the local newspaper published articles about it including pictures of the mandated color and the owner's choice side-by-side, you could barely tell the difference and there was such an uproar that the city finally relented and allowed the owner to occupy the house. There are good reasons for zoning regulations, like separating single family from commerical occupancies that I agree with that are unfortunately breaking down, but mandating dormers, porches, or roof pitches are not good reasons and do nothing but take people's freedoms away from them.
