The permit was $65 to replace my Heat Pump, Did it my self a few weeks ago. The inspection was a joke, He walked in said you do this your self, I said yes sir, He said looks good. That was it.
I agree you should pull permits, But had this not been a requirement for me to get a tax credit on my heat pump, I would not have pulled the permit.
You just gotta know when you should and shouldn't, You just have to use your judgement.
For example
I wouldn't pull one for: Replacing a light fixture, adding a light, changing a switch out, Replacing a faucet or toilet.
I would pull for: Adding a new circuit in the house, Redesigning the layout of a room by relocating walls, Changing the roof. Any job over 5k as witch doctor said.
They also told me if I replace my deck board I would need to get a permit and have it inspection.
