Another point no one has mentioned is permits. In Edmonton a licenced tradesman must pull the permit and sign off on the work then its inspected by the city (electrical, gas, plumbing, etc) . I don`t know many who would do that for someone else to do the work. I can pull the permit if I own & "occupy" the house but I can`t pull the permit for a rental property or a flip etc.
QUOTE (invst4profit @ Nov 15 2009, 05:58 PM) The final responsibility falls back on the licensed individuals doing the inspection. The purpose of the inspection is to show that the work has been done correctly and is safe.
Trades people use unlicensed individuals regularly, such as apprentices, to do all installation work for all trades but the one holding the license and signing off on the job is ultimately responsible.
The building code requires inspections of all work and I generally do have that done in any area related to safety.
With DIY the catch is finding a licensed contractor willing to OK someone else`s work.
The bottom line is if you do not know what you are doing you should always hire a licensed professional.
