A business license gives you permission to run a business within a particular territory. It is important to note that not all local governments require you to obtain business licenses, while others only require them for specific business types such as bars or restaurants. To determine whether or not your state or business type requires you to obtain a license visit SBA.gov for state-specific license and permit information.
You may want a garage door if you will need to access your shop with large workpieces or tools, or if you or future owners will ever want to use the space to park a vehicle. Garage doors are notoriously drafty, however, so if you think you can live without one you will probably be warmer. Instead, you could opt for out-swinging double doors. In a small shop you can, at a pinch, rip longer lengths of lumber by feeding the material out of either a strategically placed door or window.
I look at these workshops and wonder if I'm the only woodworker that has other hobbies that require shop space. My one car garage serves for woodworking, motorcycle storage and maintenance and home repairs. I have a floor standing drill press, Band Saw, 10" cabinet saw, lathe, 6" jointer, 3 tier tool chest(automotive tools only) 4' workbench, mortiser on a pedistal, grinder on a 16" square storage cabinet, and a roll around 40"x22" cabinet that hold my miter saw, portable thickness planer and other storage. Luckily I have an attached shed where I can keep my dust collector and compressor and have them plumbed into the shop. Right now my snow blower also resides in the shop where otherwise my 450cc KTM off road motorcycle would. I need to step outside in order to change my mind so please stop teasing me with these to die for shops. Paul
Make sure to run ground wires wrapped around all lengths of flexible exhaust hose to prevent static build up, which can spark and potentially ignite. I chose the King 1.5 HP dust collector, with a 115 volt motor, so I did not need special wiring for it. A shop vac is a must, as well, used to vacuum out machinery, and to remove dust from furniture prior to finishing. Finally, an air filtration system was installed to clear the air of tiny airborne particles. The King KAC 650 unit I installed does a nice job, has a remote control, and a programmable delay – I usually have the air cleaner run for a timed two hours when I leave the shop.
