Of the pods within the limit, 3 ship pre-wired, all from Autonomous. This rule addresses electrical power, so that condition applies to them.

The building department for the address decides whether a permit is required. This site repeats published rules and compares them with published pod sizes. Zoning rules, HOA rules and setbacks can also apply.
