Business Insider has a couple of articles about how horrible tiny houses actually are. They are behind a paywall, but one thing that stood out [and was relevant to a mere office] was this:
They need to be strapped down in areas prone to strong winds.
Would a city inspector allow me to mount a surge protector and run an extension cable, like the friend suggested [and Mom thought was a good idea?]
How much would it cost to run electricity from the house? I would have the privilege of digging a trench?
I hate digging in Arizona!
Apparently this is the correct way to run power to a tiny house:
NOCO GCP1 15 Amp 125V AC Port Plug Power Inlet with 16-Inch Integrated Extension Cord
Or you could pay the same amount for this and run wires:
