As seems to happen often these days, I'm posting this photo at the last minute — and haven't had time to find out more about the person or business there. Some online searching led me to Siobhan's page on the Model Mayhem website. I'll try to find out more soon... in the meantime, if you have details, please add a comment below...
Update (6 hours later): Elizabeth Albert answered my email to ask whether she knows anything about the building and mural. She wrote "I am actually the artist behind that mural :). I design clothing but also paint." Along with the Model Mayhem link above, her email signature has more info:
