Oh, I dunno about that.
I added a 160 sq ft laundry/sewing room and a large garage on my house. The laundry was between the existing structure and the new garage.
Although I plumbed in HVAC from the existing system, the duct was a long way from the plenum and since it's a masonary house with a flat roof and no crawl space I couldn't add a return duct.
Since the garage is also the workshop and it gets hot in Arizona, I added a cooling system to the garage. I also planned to supply additional cool air from this system to the laundry to augment that system.
I designed the addition but had a professional do the drafting and run the plans through the county plans examiners. After approval, I began construction. One of my inspections was for rough framing and mechanical. The inspector blessed the duct that ran from the garage into the laundry.
During the plumbing and electrical inspection, a different inspector looked at the duct and said, "You can't have that duct run from a garage into a living space."
I said, "Huh? This was blessed by the plans examiners and the last inspector."
He said, "I don't give a damn, you either tear it out completely or replace it with a thicker gauge sheet metal and install a heat operated damper, or your project stops here."
I went to the county plans examiners and told them what happened and they were besides themselves. I appealed to the chief inspector and his reply was, "I never overrule the inspector in the field."
I tore it out.
