@Spark you could on your own or with other hosts seek to amend the pending legislation.
I would also suggest an exploratory chat (call to find out if you can get a free brief consult, I think they see these issues frequently) with Enrico Schaeffer, who in the podcast I linked yesterday discusses representing hosts facing onerous local regulations.
If it were me, I’d try to get a free initial consultation to lay out options, and fin out what sort of retainer he would want to do a quick letter or lobbying phone call to see how to tweak #4 to keep you legal.
If you could draft a letter yourself to go out under a law firm’s letterhead, even a local law firm, and enlists several more signatories, that might make this an more affordable lobbying effort. Perhaps note that you plan additional actions [political, legal] if #4 isn’t redrafted to define cooking facilities as the inclusion of a “range, oven, cooktop or hotplate,” and that refrigerators, microwaves and electric kettles are permitted.
