You can you use office address as "mailing address"

You do not need to update your home address after you moved. You just need to update your "mailing address" if it is changed.

I use my office address as "mailing address" for all my I485, I149, I130, I175 and my home address as "home address" All letters from USCIS have been mailed to my office.

After I moved, I called USCIS to update my home address, I was told that there is no need to update "home address", just need to update "mailing address".
