Get a blower/vac. Mine's a Toro, it's been a nice thing. I think
this is the model I have.
There's two attachments that make it a blower. Take them off, two other attachments turn it into a vacuum, sucks up the leaves, grinds them up, and puts them in a canvas bag. Empty the bag into trash can/bag (or composting if you have that, I guess). Tough to be simpler.
As to being required, probably depends whether you have an HOA, and whether they have strict rules about appearance.
