STR newbie looking for more info

[Michael Guydish]

I am a newbie looking to house hack and get into STR's in the future. I have a passion for hospitality and I am graduating from SJSU soon with a hospitality degree. My question today is how can I find out if a house for sale is residential or commercially zoned? Is there a source that can make it easier for me to tell the difference? I do want to invest in STR's in the future that allow me not to live on site. I know a lot of regulations are being passed in cities that are strict. Then I hear that there are cities that have none yet, but are cracking down. So to summarize this whole thing, how can I find out if a property is residential zoned or commercial zoned? I am looking at properties daily trying to get myself familiar to see if its a good deal but I never know if I can buy it to short term rent on its own. Thanks, anything helps as I am learning!
