Austin vs Round Rock: Building Permit Fees Compared (2026)

Key Takeaways

• New home: Austin is about $1,842.04 all-in for a home up to 1,000 sq ft (estimate from verified inputs) versus Round Rock's flat $485 with plan review bundled - roughly 3.8x. Austin scales up with square footage; Round Rock does not.
• Opposite structures: Austin charges five separate per-square-foot trade lines (Building, Electrical, Mechanical, Plumbing, Energy) plus a separate plan review. Round Rock publishes one flat fee per project type with review included.
• Re-roof: Austin charges a $370 roof replacement inspection; Round Rock requires no permit at all for a re-roof (unless the roof structure is modified).
• Solar is a near-tie: Austin about $144.13 (estimate from verified inputs: $111.66 electrical permit base including the 10% Austin Energy technology fee + $32.47 intake) versus Round Rock's flat $150.
• Pools and decks: Round Rock prints flat fees ($350 in-ground pool; $125/$200/$300 deck menu). Austin does not publish a single flat pool or deck permit total - those run through a $132.86 small-projects plan review plus standalone inspection fees.
• No state levy in either city. Austin's only percentage add-on is a 10% Austin Energy technology fee on Austin Energy/solar line items; Round Rock adds no city surcharge but doubles the fee if work starts before a permit.

How Each City Structures Its Fees

These two cities could not price permits more differently. Austin prices residential permits per square foot, tiered, and charges the dwelling permit as five separate trade lines - Building, Electrical, Mechanical, Plumbing, and Energy - with plan review billed separately on its own tier table. Round Rock publishes a flat-fee menu: one number per project type, with residential plan review bundled into the permit fee ("no additional fees will be added to the permit fee," per its live pages). Note the scope difference in the table: Austin's five trade lines bundle the trades into the dwelling permit, while Round Rock's $485 covers the building permit (review included) and standalone trade permits are $50 each when pulled separately.

Source vintages differ and this is not a like-for-like comparison of dated documents: Austin's figures come from its FY 2025-26 fee schedule (effective October 1, 2025, current). Round Rock's figures come from its current live department pages, which carry no printed effective date (they reference 2024 codes; the companion fees PDF is marked "Updated August 2023").

Worked Example: New Home up to 1,000 sq ft

Same assumptions in both cities: a new single-family home of up to 1,000 sq ft, permit-office charges only (utility, meter, and impact fees excluded in both).

Austin's $1,842.04 total is arithmetic from verified line items on the FY 2025-26 schedule ($838.82 + $896.50 + $106.72) and is labeled an estimate from verified inputs. The 1,000 sq ft tier is Austin's base (floor) tier: every trade line and the plan-review tier step up with square footage, so a larger home costs more than this in Austin, while Round Rock's building permit stays $485 at any size. Scope note: Austin's total bundles the five trades into the dwelling permit; Round Rock's $485 is the building permit with review bundled, and standalone trade permits are $50 each when pulled separately - the two totals are close in scope but not perfectly identical.

Which City Is Cheaper?

• New construction: Round Rock, decisively. Its flat $485 (review bundled) is roughly 3.8x below Austin's ~$1,842.04 all-in at the 1,000 sq ft floor, and the gap widens as Austin's per-square-foot lines scale up on larger homes. Caveat: the scopes are close but not identical (see the worked example note), and the source vintages differ.
• Demolition: Round Rock, $50 flat versus Austin's $73.70.
• Re-roof: Round Rock - no permit is required for a re-roof (unless the roof structure is modified), versus Austin's $370 roof replacement inspection. See the Austin roof replacement permit guide for the full Austin picture.
• Solar: Effectively a tie. Austin is about $144.13 (estimate from verified inputs, including the 10% Austin Energy technology fee and the $32.47 intake fee) versus Round Rock's flat $150.
• Pools and decks: Round Rock is the predictable one - $350 in-ground pool, $125 spa or above-ground pool, and a $125/$200/$300 deck menu (see the Round Rock deck permit guide). Austin does not publish a single flat total for either, so no dollar-for-dollar winner can be printed; budget Austin's $132.86 small-projects plan review plus $67.10 per standalone inspection and confirm the rest with the department.
• Trade-only work: Round Rock's standalone trade permits are $50 flat; Austin itemizes (a residential HVAC change-out, first system, is $67.32). Small edge to Round Rock.

When This Comparison May Not Apply

• Different source vintages: Austin's numbers are from a dated, current FY 2025-26 schedule (effective October 1, 2025). Round Rock's come from live department pages with no printed effective date (the dated companion PDF is "Updated August 2023"). If Round Rock has adopted newer figures without updating its pages, its side of this comparison would shift.
• Scope is close, not identical: Austin's dwelling permit bundles five trade lines; Round Rock's $485 bundles plan review but prices standalone trade permits at $50 each when pulled separately. A project that pulls multiple standalone trades in Round Rock will cost more than the headline flat fee.
• Permit fees are not total project cost: Both cities bill utility, water/wastewater, and impact fees separately - on new construction those routinely exceed the permit itself. Round Rock's water and wastewater impact fees, for example, are charged per LUE on top of the $485.
• Larger or unusual homes: The worked example uses Austin's base tier (up to 1,000 sq ft). Bigger homes move Austin up its tier tables, so the 3.8x ratio is a floor-tier snapshot, not a constant.
• Penalties change the math: Round Rock doubles the permit fee when work starts before a permit is issued. Austin applies a 10% Austin Energy technology fee, but only on Austin Energy/solar line items.
