Never. Not since the heady days of 2E in the mid 1990's have we used any homebrews. And those were just joke spells we made up on the spot to deal with the DM's little brother's ANNOYING character, lol. The fact that lots of smokeables and sleep deprivation were usually included- had much to do with it, too. Funny Bigsby's variants, mostly. (nostrilific nullifier; Bitch slappin back hand*; Fizban's Ferocious Fart.- like stinking cloud with visual and audible effects!)
Since then? Nope. There are thousands of spells already created- every edition prior to this had many scattered throughout modules, campaign settings, splat books, etc. If we needed something new and interesting, we'd just add a few of those in. Mainly via NPC casters, found spellbooks, scrolls, and wands, etc. But sometimes, if a character really wanted to learn a spell from a source other than the PHB, we'd allow it. (subject to review of course)
Forgotten Realms was a perfect example- and a great source of ideas to glom, even if you didn't play that setting. There are a huge number of FR specific spells- even if you only mined the 3E releases! I liked them for the flavor- having played since the early 80's, some variety to spice up the magic game was very welcome.
* the best part of the bitch slappin' backhand spell was that after the giant hand smacked you onto your butt, an illusory gully dwarf would momentarily appear, glare at you, and call you a bitch. This spell was tailor made to cast on Drew's character Razor Lips- a Goblin fighter, who went out of it's way to make just about all of the other characters hate him. (just a TOUCH of sibling rivalry going on there...) We needed players. That's why.
