Electricity to a build site

Does anyone know if you can get electric to a build site before a home is built on it?

We'll be building a tiny home this summer and living in it while we build our bigger home over the next year or so, and we're going to need electric to the site to use the tools we need, and also to work for our business (we work from home online).

Is this going to be a problem? Who governs rules about this? Would it be the electric company supplying the power to the built site? The county?

It's rural property, btw.

Contact your local electric company and it should not be a problem. Most sites have electric before the home is built. My property has a power box set up with several outlets on its face. Might look something like the photo below.

Yep, Call the power company and tell them you need temp power for a building site.  You will probably be responsible for the cost of the temp pole and box, depends on your particular power company.  If you are responsible for that cost, cruise Craigslist or the like in your area and see if you can find a used set-up.
