Florida exemption
You may build 2 house's ayear as an Owner builder. That is you are building the home for yourself. You will still need licensed electricians, plumbers, hvac, septic and well professionals. YTour plans must be engineered by a Florida engineer but can usually be drawn by a drafting service. there are other ways to get plans that are rated for floridas tough requirements. Coastal areas are the worst of course. Depending upon the relationship you develop with the local bldg dept I was able last year to build 2 small additions and got the inspector to allow me the courtesy of doing my own elect and plumbing. They don't have to allow you that tho. A County lic can be aquired but if your going to go thru the testing process you might as well get State certified. I believe the state dept of professional regulation is where you'll find worthwile information about requirements.(think it myflorida.gov) Either test you take , you must purchase the books and take a class on how to test. The test are all open book. You have to be able to locate the answers in the book. thats the whole test. I plan to relocate to Polk county this Fewb and I will probably build a spec home. I will go after my lic this spring tho. It's actually a coveted thing to have in Florida with the stringent requirements upon the construction industry. Hope this is helpful.
