The only reference to clearance is for structural members
NFPA 13 – 2016 edition: 9.3.4.9 The installed horizontal and upward vertical clearance between horizontal sprinkler piping and structural members not penetrated or used, collectively or independently, to support the piping shall be at least 2 in. (50 mm). If it were a branch-line with sprinklers then per NFPA 13 -2016 edition: 9.3.4.11* The installed clearance between a sprinkler and structural elements not used collectively or independently to support the sprinklers shall be at least 3 in. (75 mm). Nothing referencing Mechanical that I know of.

This way I’m not challenging them, but seeking their assistance. When they can’t produce any reference, the issue goes away. I copy key people on the project so that they are aware of the issue. It’s just a more diplomatic way of saying “prove it”. The fact is that most AHJ types or reviewers only review the drawings associated with their specific area of responsibility. They do not care about coordination, that’s part of the responsibility of the design professional. So they would most likely never pick up on something like this during permit reviews.

There is a 6” main that is about 1/2” from the ductwork. Of course, the inspectors response is “it’s in the code book” when asking for a reference that mandates clearance to hvac ductwork. Has anyone run into something similar? Note: this is not a high temp duct that would cause for enough heat to convert the sprinkler water to steam.
