Do you have to have a smoke detector if you own the home? No. You can disconnect or disable without penalty. It is required to be active only during a sell or if in a commercial residence (i.e. rental property, hotel, apartment, ect).
Do you have to your electrical outlets grounded? No. Even if you sell the home, it does not have to be brought up to code...AND...if you do the electrical work yourself, there is no requirement to meet code.
How many pilots are there? Because I'm going to bet that there are more people without certification than with. So it is not required as a condition of living.
