Worked Examples - Real Solar Projects in Austin
The examples below use the exact schedule lines: the $169.83 solar electrical permit base and the $53.56 Auxiliary Power intake fee. The separately printed $84.92 solar inspection fee (1-50 kW) is shown where it may apply. The permit does not scale with array size.
A homeowner installs a standard rooftop photovoltaic system with no service upgrade.
- Solar electrical permit base: $169.83
- Auxiliary Power intake fee: $53.56
- Total permit cost: $223.39
This is the base all-in permit figure for a residential rooftop system that does not need a service upgrade. If the separately printed $84.92 solar inspection fee (1-50 kW) is billed, the total would be $308.31.
A homeowner installs a larger rooftop system on a bigger home.
- Solar electrical permit base: $169.83
- Auxiliary Power intake fee: $53.56
- Total permit cost: $223.39
The Auxiliary Power solar lines are not tiered by array size, so a bigger system carries the same permit lines. Structural roof review, if needed, is separate.
A home needs an electrical service/panel upgrade to support the new array, filed separately.
- Solar electrical permit + intake: $223.39
- Separate service/panel upgrade permit: department-priced
- Solar side is $223.39 ($308.31 if the $84.92 solar inspection fee is billed); the upgrade is a separate line
A service or panel upgrade is its own electrical permit and is not part of the solar Auxiliary Power lines - ask Development Services how it is priced for your project.
When This Estimate May Not Apply
The $169.83 solar electrical permit base and $53.56 intake fee come from Austin's current FY 2026-27 schedule. Route your project to Development Services before relying on a figure if any of the following applies:
- You need a service or panel upgrade. That is a separate electrical permit, filed on its own, and is not part of the solar Auxiliary Power lines.
- You are adding battery/energy storage. An energy-storage system can carry its own review and is not the rooftop solar permit.
- The roof needs structural reinforcement. Structural review for added load is separate from the electrical solar permit.
- Ground-mount or commercial solar. Non-rooftop or commercial systems can follow different lines and reviews.
- Austin Energy interconnection engineering is involved. Interconnection studies beyond the permit are handled by Austin Energy separately.
- HOA approval applies. Homeowners-association review is separate from the city permit.
A separate service upgrade, battery storage, structural review, ground-mount/commercial scope, interconnection engineering, and HOA rules are all excluded from or may change the solar figures on this page, and the page-standard disclaimer applies - always verify with Austin Development Services before budgeting.
