I had a thought the HOA would be a problem, especially with an annoying neighbor. I wonder if you can get a metal, or build a wood-framed "Water Heater" cabinet to attach to the back wall, then run a "pipe" back into the garage? You'll need to make sure it has a vent so you don't develop back pressure, but you could line it with sound absorbing material to avoid annoying the neighbor and generating complaints. If you show you mean to make it nice looking and paint it to match the house, you might be able to get it approved. Let them know the alternative is for you to haul all the saws out into the driveway for use, which will be noisier and disturbing to the neighbors. I suspect they will prefer a nice looking, noise canceling enclosure to having your saws out on the driveway.
This is not only a dust collection, but a local politics issue. So if you make it clear, in writing, that you only have a few options to continuing your hobby while being a good neighbor. Most garages have air vents, and you may be able to use part of one to pass the pipe through. I'd be a little less happy about cutting through a wall, but the cabinet will conceal that. Politically I'd present my plan as trying to be nice to the neighbors. I believe most HOAs members know who the annoying people are and will be more likely to approve a small, out of sight solution that reduces the number of noise complaints. Both you and the association know full well that pulling your saws out is guaranteed to set off the easily annoyed. And that you are having either a stock cabinet or a pro carpenter build one, tells them you are doing your best to conform to HOA rules.
You will need to have a sizable air exhaust in that cabinet, and you can buy a cover that holds a large filter, but has vanes that keep rain out. The second filter will completely stop wandering sawdust from triggering a complaint.
One other alternative to consider is to put the filter where it returns the air back into the garage. This will preserve your conditioned air, and also allow you to soundproof the DC cabinet, which may appeal to your HOA. If you can build the cabinet, you can keep the garage door closed when using your noisy tools, and you can soundproof the garage door using heavy, spongy material that, again, won't be visible to neighbors. WIN WIN. If all else fails, you could set up a chamber with non supporting walls INSIDE the garage, which will eat a little space, and still give you the double filtration I spoke of.
The more I do, the less I accomplish.
