Best I've seen so far. Thank you.

Love the video and exactly what I needed. Can you please make a 2021 video tutorial? Yours is one of the best I found online. Thanks.

Very Helpful info

Nice, manageable intro. Comment on confusion of "new v. existing" at 8:45 to 10:40: Owners may say, "But my building has been there since 1987, so we're exempt from the new life-safety code until we remodel." Wrong. They're still required to follow the new code (depending upon the state's adopting statute language), but only the sections pertaining to an "existing" occupancy of that type. If the new code contains life-safety provisions that are more stringent than what was previously built, and they don't want to upgrade, they must look in the "existing" occupancy section for a specific exemption such as the form of "Existing previously approved installations may be continued in use," including any specific proviso for that exemption. For instance, in an existing education occupancy: "15.2.9.2. Approved existing emergency lighting installations shall be permitted to be continued in use." (2015). However, in the 2000 edition (15.2.9), existing education occupancies were required to install emergency lighting in (at least) all of the listed locations. If they didn't do it back then, they're certainly not exempt now. Thus, the NEW code (meaning the latest adopted edition) provisions for EXISTING occupancy (meaning previously built) may certainly require construction or operational upgrades in order to legally continue that occupancy in that building. How an owner proves the "existing approved" condition actually qualifies is a matter of AHJ policy and documentation.
