I want to build a Tandem House on a property zoned for it. Seeking as much information as possible. Has someone done one yet? I hear they are rare so far. Zoning/permitting issues? Cost vs ADU? Highest and best use of property? Specific experience or insights? Builder familiar with it?

Kelly you are revealing my secret strategy!
I love this idea and have recently built several tandem houses. The most common form (with garage underneath) can be seen at 2268 S Acoma, which is behind 2266 S Acoma. Please don't bother the tenants.
Resale value is the main problem with them. (Almost) Nobody wants a carriage house as their primary residence, but they make fantastic rentals.
I thought if I built one on a corner, the resale value would be as high as one side of a duplex unit. I was wrong. I built one on Harvard Avenue behind the original 1947 house. It cost $380k to build, but I couldn't sell it for more than $495k, so I'm keeping it and renting it for $2600/month. The half duplexes in the same neighborhood are selling for $600k.
Besides Landmarkk, the leading Tandem House architects in Denver are:
