Since you are in CA and probably a seismic zone "D" I would think ASCE 7 would apply

2021 IMC

2021 IBC


Non Structural Components would include HVAC systems

What kind of registers? 2x2 that fit in the grid system? linear slots that the grid is built around? just saying "registers" leaves it pretty wide open...

Make Up Air unit

The acronym for that would be MUA. I did an Internet search for "MUA Register" and all that came back was things like links to Mauritius, or to registration for some conference in Las Vegas.

General rant: As a chronic curmudgeon, I hate it when people make up acronyms without defining them, and I have to say that this forum is where I see it more than anywhere else in the real world or the cyber world.

The acronym for that would be MUA.

Nice catch, it didn't click with me that the A and U were backward.

As far as a Makeup Air register, the ones I see that are specifically designed for makeup air are the large boxes with perforated bottoms attached to the front of the hood, and typically supported with the hood. They are an accessory ordered with the hood. Everything else I see is standard HVAC registers and should therefore be supported the same as any other register.

I was taught the if you are going to use an acronym, the first time you spelled the words out then provide the abbreviation in parentheses.

In accordance with (IAW) the Massachusetts State Building Code (780 CMR) section ...

 

[ICE]

808.1.1.1 Suspended acoustical ceilings. Suspended acoustical ceiling systems shall be installed in accordance with the provisions of ASTM C635 and ASTM C636.
The ICC ESR for the ceiling will most likely have a statement that grid will not support anything other than itself.

 

[TheCommish]

Would say that Ice statement is acceptable as they are know abbreviations
