Zoning in Park Hill, Denver.

[James Carlson]

I'm helping a buyer who wants a home in Park Hill, Mayfair, or Congress Park. He wants the option to build a carriage house out back and so I was going to set up a search filtered through zoning descriptions with a '1' attached to the last letter -- U-SU-C1, for example, or U-TU-B1. Those allow for one accessory unit on the property. But I then looked at the zoning map, and there are no such zoning designations in this buyer's desired areas.

Am I missing something? Are there any "secret" pockets of this type of zoning sprinkled throughout the zoning overlays? Maybe on a corner lot or something? 

Thanks for any help.
