Re: Looking to start up bakery, where to rent?!
I know people who run a small bakery operation from home, you just need a food handling license and, probably, permission from your landlord to run a business from his property.
I also know someone who rented a small industrial unit and converted it to a kitchen for catering prep, again, a food handling license and landlord permission was, I think , all that was needed.
There will be restrictions on some properties re what they can be used for, but I think they are mostly residential/commercial/retail.
Re the food hygiene permit, the inspectors, in my experience, are really helpful.
Good luck and let me know what you are planning on baking!
