Round Rock's cost page should read differently from Austin because electric service is tied to Oncor delivery and retail-provider choice rather than Austin Energy. Its 2002 median structure year means many homes are relatively newer, but Level 2 installs still hinge on a city electrical trade permit, torque-letter documentation for upgrades, and panel capacity.
Permit path
Permit required: Yes
Round Rock's standalone trade-permit page covers contractor applications for electrical work that is not part of a larger remodel or new-build project. The city says electrical upgrades or replacements require a torque letter upload, an inspection is required when pulling a permit, and two inspections of the same type are included in the permit fee.
Published permit fee: $50 standalone electrical, plumbing, or HVAC trade permit fee; additional failed inspections of the same type after two included inspections are $75 each.
