Mark is correct. You will need permits in Houston or most areas that are within city limits. Professional contractors will know what you need and what is necessary to do. I recommend speaking to several contractors to get bids on what you are looking to do. Also request references so you can see and speak with people about the work they have done in the past.
Hope this helps.
