Lots of properties with mother in law suites and other accessory dwelling units called “carriage houses”.

@Mario Russo the coveted 4 plex can be difficult to come by in this area.

If you are renting them maybe you can build the main house and an accessory structure that is smaller but could still be rented out. 

Make sure that your Realtor knows which apartments are grandfathered and which are subject to the Town's accessory dwelling rules; that'll bite you if they're not aware.

I was under the impression that City of Denver only allowed primary residences to file for a permit, and the city was considering allowing accessory dwelling units.

The roof, crawl space and foundation were in excellent condition as the house was only 15 years old.The plan was to carve another bedroom out of the main house (making it a 4/2.5) and turn the rear unit into a 2-bedroom, 1-bath accessory dwelling unit (ADU, or backyard cottage).RehabThere was almost no work to be done in the main house--some expensive fixes like replacing the furnace and carving out the 4th bedroom from all the space available, but all in all, about $15K with carpeting, paint, trim work, and plumbing fixes.The ADU was the heavy lift.

Just wondering if any of u  bought a accessory dwelling units from modal?

I was going through the forums and saw someone posted about running a comp on the main house and the other home as an accessory unit.

You might able to get away with it just being listed as a duplex with an accessory dwelling.

Other accessory "helpers" would be a home inspector (hired by the buyer), and the appraiser (contracted through the lender....again, when a loan is involved).In states where attorneys are required the process plays out somewhat differently.
