I don't know of any spaces in bothell but the two ways I've found spaces to do this type of thing before is looking on craigslist and just walking around and calling for rent signs. Usually if it's a commercially zoned place the signs will say so or it's obvious because it's already in a commercial space
You might wAnt to find a group of people ahead of time becaue you not only will have a chunk of rent that needs to be divided between several to be affordable but with com buildings you have triple net and other taxes to deal with if the space is legit. You will probably have alot of building out to make the space usable for multiple functions so extra hands is good.
If you don't have other interested artist pals craigslist is good for this as well becaue there is more of a void of this kind o space in bothell you will probably get a decent amount of responses and be a bit picky. Plan a meeting to discuss what your goals are from the endeavor and meet the potentials to see what they want and find copacetic artists
It can be quite hard to run a space and more expensive to both your time and money but very rewarding. That said when I founded a space in Seattle years ago I found most of my time went to running the building, filling spaces when people flaked and very little went to my own work. Make sure you're in hole heartedly before you sign a lease
You might want to talk to a lawyer ( artist trust can put you in touch with one for the arts that does probono or sliding scale work) and work out some contracts so your covered if things go screwy. Figure out if you wanna run t collectively or you're the big boss and then cover your ass
You will also have to get insurance on a com building which can add cost. When you're looking at options get something that covers your stuff as well as if someone breaks their neck in your space. The coverage I ended up with even covered instances where if my work hurt someone outside the space (ie if a sculpture fell on someone at another show space) adding on to the insurance you have to legally have wasn't too much extra. There is also a required homeland security charge in insurance that no one could really explain to me why those extra few bucks were tossed into insurance other than it's the law
It will probably take you several months to build out studios and com space, unless you're really lucky and find something already laid out, so take that down time in consideration and the hardware store costs. The 4000 sq foot bld I had already had studios somewhat divided but we still ended up sinking about 2000 collectively into it to create two more spaces and upgrade other areas (and that was with free tool rentals since a member worked at a tool place) most of that was drywall and lumber. Later we had to fix some electrical that we split with our landlord but was also a chunk of cash. So keep in mind when you're looking for a space how much work you're gonna have to do and what your resources are ( get at least one sculptor for a studiomate so you have someone good at construction if you aren't so inclined). Host some fundraisers before if you can and after it's open to help defray costs. Also anything you do to the building legally is the property of the owner in most cases so remember you're gussying up their property too well can bite you in the ass if you don't have good landlord relations and they just see you as a way to hike the rent up more for someone else you're safe for a while in this regard with the economy but if you go see that lawyer take them a copy of the lease and make sure they can't yank it from you after you've rented a year and made it desirable by other parties
