Permit process - Dallas

[Michael H.]

I purchased a home in Dallas that I plan on remodeling. Can I pull my own building permit and sub out licensed electricians and plumbers? I read it’s possible if you homestead the property. However, I don’t live there so not sure if it can be considered homestead. 

Never pulled a permit. Can someone tell me what is the process? I believe you file a permit application with a plan. Once approved, then what? 

What is the turn around time these days to get building permit approved?
