How to bring things up to code

[Charles Peralta]

Hey BP community! Had a quick question for you this afternoon. How would i go about learning all the requirements and code for real estate in my area? I primarily want to know how big certain dimensions of the house have to be (i.e. Closet, how big a door has to be). I know I will learn this throughout my deals but I would love to do some homework on it before hand. Thank you!
