You might be able to make some basic framing without any sheating without a permit. Then hang your cabinets on that. Best would be to ask your local permit office though. Any new power runs will need a permit regardless.

However, I will say if you want to do any power wood cutting then you’ll want to enclose it real well. (ask me how I know, actually on second thought, don’t lol)

I have a hobbiest’s woodshop in a portion of my unfinished basement. No cabinets, but I do have a 15 foot or so long workbench with a miter saw in the middle of it. It has a few pull out shelves and this gives me a lot of storage. I also have a very overbuilt 4’x5’ table on wheels that has two shelves below the top. I initially intended this to be an outfeed table for my table saw. My basement has a drop ceiling, painted cement walls, and a linoleum floor.

Others have touched on permits and framing, so I’ll leave that alone.

Dust collection and air filtration are going to be must dos. I have the harbor freight dust collector connected to both my table saw and my miter saw via eye with blast doors so I can funnel 100% of available flow to the tool in use. The miter itself sits inside a pretty large hood. This works fairly well, but it’s not perfect. You’re going to want to build some kind of filter box (a cube or rectangle with filters on four sides and a fan pulling air through them, into the box, and out). Here’s an example.

I’d but some wood and frame it out instead of hanging anything directly to the block

I did up my garage by first lining the walls with 18mm construction ply (on 2x1s) and the (rough concrete) floor with cheap 4mm ply and speed nails. Ten years and about four or five major redesigns later, I feel it was well worth it for the convenience of being able to hang whatever wherever, whenever, quickly. And the floor was a fast fix, allowing me to easily roll various heavy things around. It’s also quite bright (bare block had the place looking like a dirty, dingy dungeon). The 2x1s allowed for easily rewiring and adding plenty of new sockets, very tidy.

Building permits are a thing because people who don’t know what they are doing would create dangerous conditions.

Permit or not, make sure you do your research first.

I’ve had to fix so many home “improvements” that I usually suggest people don’t go at it alone.

I agree that framing it is the right way to do it. You might not need a permit if you’re not closing up the framing and aren’t planning to run new electric lines. Check with your local permit office. They will be happy to tell you what is and is not required. They are not police, so they aren’t going to do any investigations later on.

Framing for something like that isn’t too tough if you’re a semi-decent woodworker. Youtube should have enough info. Just do the framing correctly so that if you want to do proper finishes later you’ll already have it.

For the floor, it is probably better to leave it unsealed. Properly sealing a concrete floor is not trivial and doing it wrong can cause bigger problems. If you don’t want to work directly on concrete, consider some interlocking foam/rubber squares.
