Adding a additional duct into the garage

I have a 1750 sq ft house, that was built in '97. The garage is attached with 1.5 walls which are inside walls...
Is it feasible to run a duct for heating this space with my current furnace? I'm not looking to make it 70 degrees in there, but something warmer than the very cold nights we have...
FWIW, I'm in the Detroit area.

that would be against code, and dangerous to boot.

you should have hvac in the garage independent of the living space, so that fumes aren't mixed into the living space air.

You don't as it against building codes. Look into supplemental heat of some sort. Solid fueled stoves are not allowed in garages either so you have to look at propane, electric, or kerosene.

Bad idea on many levels.
May I ask why you would be willing to spend good money heating a garage. Other than when you are working on a car or other project, what needs heat? The cars a likely better off cold.

Consider quartz infrared heaters. They start heating instantly and heat objects and people, not the air; so you feel comfortable even though the garage door may be open. Mounted over the car, the heaters will de-ice a car in a few minutes.
I have two 1500 watt units mounted on the ceiling of my 2-car garage and they're perfect for those odd times when I want to work on the car or do some carpentry. You'll need a 220 volt line of sufficient capacity, of course. You can control the heaters with switches or thermostats. Thermostats are the safest in case someone leave the heaters on by mistake. I seldom operate the heaters for more than a few minutes and shut them off when I'm not in the garage, so the electricity use isn't significant.
As a bonus, quartz infrared lamps give off a lot of light -- makes it easy to see under the hood.
The units I have are mounted on standard "J" boxes and were made by Fostoria; but I don't know if they are still available.

I had a new furnace installed in the garage a couple of years ago and had them run a duct over to the workbench area for just the purpose you stated. Works fine and the installing company made no mention of any code issue. And I don't see what any issue could be. I keep the vent closed except when I want the heat.

I don't think it is a code violation to install a heat run to the garage, only a code violation to have a return duct there- That said it would add to problems balancing the remainder of the system and be difficult to properly control without a return- A seperate heater would be a safer, more efficient idea-
