Several craftsmen and service people I know use these self storage sites for
warehousing of supplies or equipment. Nobody I know uses them for work
because they lack power outlets, have no a/c or heat (except the more
expensive units) and no windows. I have had storage space in 3 different
locations over the last few years and none of them allowed on-site work
(even hobbyists)...they let you access your unit as much as you want to move
stuff in and out, but no on-site work. I guess that's just one of the
reasons local woodworking co-ops exist....besides borrowing tools :-) I
would look to see if there is a co-op in the DFW area.
