Round Rock TX Building Permit Fees (2026)
Actual residential building permit fees from the City of Round Rock Planning and Development Services, Building Inspection Division - taken from the department's published fee pages, retrieved June 10, 2026. Round Rock is in Williamson County on the I-35 corridor, about 20 miles north of Austin.
This page covers: The flat $485 building permit fee for new single-family, townhome, and duplex construction (plan review bundled), the flat per-project fees for decks, patios, sheds, pergolas, pools, garage conversions, generators, solar, foundation repair, and demolition, and the $50 standalone trade permits - all as published on the Round Rock Building Inspection Division department pages.
Trade permits are SEPARATE: Standalone electrical, mechanical/HVAC, plumbing, gas test, and irrigation permits are $50 each. Two inspections of each type are included in the fee; a $75 re-inspection fee applies once the same inspection type fails twice.
Utility and impact charges are SEPARATE from the $485: A 5/8" water meter is $320, the water/sewer line fee is $200, roadway impact fees are based on plat recordation, and water/wastewater impact fees run per LUE by meter size (post-January-2024 plats: Water $4,912 per LUE, Wastewater $2,921 per LUE). These are billed outside the building permit fee and can far exceed it.
Texas has no statewide levy: Texas adds no statewide percentage building-permit levy, and Round Rock adds no city percentage surcharge on the flat permit fees.
This page does NOT cover: Remodel, finish-out, and addition pricing is not printed here as verified (the department's method for those project types is in transition - see the limitation notes below), and zoning, platting, and site-development review fees are separate. Source-currency caveat: the department's live fee pages print no effective date, and the only dated companion PDF is "Updated August 2023" - treat every figure here as subject to confirmation with the Building Inspection Division (512-218-5428).
Round Rock charges a flat $485 building permit fee for a new single-family home, townhome, or duplex - at any size - and plan review is bundled in ("no additional fees will be added to the permit fee" per the department). Most other residential projects use a flat-fee menu: an in-ground pool is $350, a covered deck with electrical is $300, an uncovered wood deck is $125, a shed is $50, and solar is $150. Standalone trade permits (electrical, HVAC, plumbing, gas test, irrigation) are $50 each. Utility and impact charges - a $320 water meter, a $200 water/sewer line fee, and per-LUE impact fees - are billed separately. Texas has no statewide levy, and Round Rock adds no percentage surcharge.
- A new single-family home, townhome, or duplex is a flat $485 building permit fee at any square footage, with plan review bundled - no separate plan-review line is added.
- Utility and impact charges are separate from the $485: a 5/8" water meter is $320, the water/sewer line fee is $200, roadway impact fees depend on plat recordation, and water/wastewater impact fees run per LUE by meter size (post-January-2024 plats: Water $4,912 per LUE, Wastewater $2,921 per LUE).
- Most small residential projects are flat: in-ground pool $350, garage conversion $300, covered deck with electrical or plumbing $300, covered deck without $200, generator or solar $150, uncovered wood deck or pergola $125, spa or above-ground pool $125, foundation repair $125, shed $50, complete demolition $50.
- Standalone trade permits are $50 each (electrical, mechanical/HVAC, plumbing, gas test, irrigation), with two inspections of each type included; a $75 re-inspection fee applies after the same inspection type fails twice.
- A residential fence needs no building permit, and a re-roof needs no permit unless the roof structure is modified. Starting work before a permit is issued doubles the fee. Texas has no statewide building-permit levy.
How Round Rock Prices a Residential Permit
Round Rock uses flat per-project fees rather than valuation tables or per-square-foot rates for the project types below. A new home is one flat $485 fee with plan review bundled; small residential projects each carry their own flat amount, and standalone trades are $50 each. The tables show the verified figures exactly as published on the department pages (retrieved June 10, 2026 - note the pages carry no printed effective date).
New single-family / townhome / duplex construction
| Item | Fee |
|---|---|
| Building permit (new SFD / townhome / duplex, any size) | $485.00 flat |
| Plan review | Bundled - $0 extra |
| 5/8" water meter (separate, not in the permit fee) | $320.00 |
| Water/sewer line fee (separate) | $200.00 |
| Roadway impact fee (separate) | Based on plat recordation |
| Water / wastewater impact fees (separate) | Per LUE × meter size* |
*For plats recorded after January 2024: Water $4,912 per LUE, Wastewater $2,921 per LUE. The department states "no additional fees will be added to the permit fee" for the $485 new-home permit - plan review is included and expedited review is not offered.
Flat residential project fees
| Project | Fee |
|---|---|
| Wood deck / uncovered patio (no electrical or plumbing) | $125.00 |
| Covered deck / patio (no electrical or plumbing) | $200.00 |
| Covered deck / patio with electrical or plumbing | $300.00 |
| Shed (plastic or wooden, no electrical or plumbing) | $50.00 |
| Pergola / gazebo (no electrical or plumbing) | $125.00 |
| Accessory structure with electrical/plumbing (pergola, gazebo, outdoor kitchen, studio shed, detached garage) | $300.00 |
| Spa / hot tub or above-ground pool | $125.00 |
| In-ground swimming pool | $350.00 |
| Garage conversion | $300.00 |
| Generator | $150.00 |
| Solar panel | $150.00 |
| Foundation repair | $125.00 |
| Complete demolition | $50.00 |
Standalone trade permits
| Trade permit | Fee |
|---|---|
| Electrical | $50.00 |
| Mechanical / HVAC | $50.00 |
| Plumbing | $50.00 |
| Gas test | $50.00 |
| Irrigation | $50.00 |
Two inspections of each type are included in the permit fee; a $75 re-inspection fee applies after the same inspection type fails twice. Starting work before a permit is issued means a double fee. A residential fence needs no building permit (checking with Code Enforcement at 512-218-3329 is advisable), and a re-roof needs no permit unless the roof structure is modified - then a residential remodel permit applies. Remodel, finish-out, and addition pricing is not printed here as verified - contact the department (512-218-5428). Reminder: these figures come from department pages with no printed effective date; the only dated companion PDF is "Updated August 2023" - verify before budgeting.
Round Rock Permit Fee Components
A Round Rock residential total is unusually simple: the flat building permit fee (with plan review bundled), any separately priced $50 trade permits, and - for a new home - separate utility and impact charges that sit entirely outside the permit fee.
| Component | Amount | Status |
|---|---|---|
| Building permit fee | $485 flat (new home) or per-project flat fee | Exact schedule figure; plan review bundled |
| Standalone trade permits (electrical, HVAC, plumbing, gas, irrigation) | $50 each | Separate - priced and paid on their own |
| Plan review | $0 - bundled into the $485 | "No additional fees will be added to the permit fee" |
| Water meter (5/8") + water/sewer line | $320 + $200 | Excluded - billed outside the building permit fee |
| Roadway impact fee | Based on plat recordation | Excluded - separate schedule |
| Water / wastewater impact fees | $4,912 / $2,921 per LUE (post-Jan-2024 plats) | Excluded - can far exceed the building permit |
There is no percentage surcharge on a Round Rock permit and Texas has no statewide building-permit levy - the flat fee is the fee. Remodel, finish-out, and addition pricing is not reproduced here because the department's method for those project types is in transition; call the Building Inspection Division at 512-218-5428 for those figures.
Worked Examples
Because Round Rock uses flat per-project fees, the arithmetic is simple - each building-permit figure below is the published flat amount, with no size-based or valuation-based math. New-home totals separate the exact $485 permit fee from the utility and impact charges that are billed on their own.
Example 1: New Single-Family Home (Any Size)
| Fee Component | Rule Applied | Amount |
|---|---|---|
| Building permit | flat, any size | $485.00 |
| Plan review | bundled | $0.00 |
| Building permit total (exact) | $485 + $0 | $485.00 |
| + 5/8" water meter (separate) | flat | $320.00 |
| + Water/sewer line fee (separate) | flat | $200.00 |
Assumptions: The building permit is a flat $485.00 at any square footage, with plan review bundled - an exact schedule figure. The 5/8" water meter ($320), the water/sewer line fee ($200), roadway impact fees (based on plat recordation), and water/wastewater impact fees (post-January-2024 plats: $4,912 per LUE water, $2,921 per LUE wastewater) are billed separately and can far exceed the permit fee.

Example 2: In-Ground Swimming Pool
| Fee Component | Rule Applied | Amount |
|---|---|---|
| In-ground pool permit | flat | $350.00 |
| All-in total (exact) | flat fee | $350.00 |
Assumptions: An in-ground swimming pool is a flat $350.00 building permit. A spa, hot tub, or above-ground pool is $125.00 instead. Any standalone electrical work for the pool would draw a separate $50 trade permit. Source: City of Round Rock Building Inspection Division department fee pages, retrieved June 10, 2026.
Example 3: Decks - Covered With Electrical vs. Uncovered Wood
| Project | Rule Applied | Amount |
|---|---|---|
| Covered deck with electrical or plumbing | flat | $300.00 |
| Covered deck / patio (no electrical or plumbing) | flat | $200.00 |
| Uncovered wood deck / patio (no electrical or plumbing) | flat | $125.00 |
Assumptions: Round Rock prices decks by whether they are covered and whether they carry electrical or plumbing - $300 covered with a trade, $200 covered without, $125 uncovered wood. Each is a flat fee, so the all-in is exact. See the Round Rock deck permit guide for a full walkthrough.

Example 4: Small Flat-Fee Projects - Shed, Solar, Trade Permit
| Project | Rule Applied | Amount |
|---|---|---|
| Shed (no electrical or plumbing) | flat | $50.00 |
| Solar panel or generator | flat | $150.00 |
| Standalone trade permit (electrical, HVAC, plumbing, gas, irrigation) | flat, each | $50.00 |
Assumptions: Each of these is a flat fee, so the all-in is exact: a shed (plastic or wooden, no electrical or plumbing) is $50, solar or a generator is $150, and any standalone trade permit is $50 each. Two inspections of each trade type are included; a $75 re-inspection fee applies after the same inspection type fails twice.

Read before you budget from these examples
- The $485 new-home fee is exact but is only the permit: the water meter ($320), water/sewer line ($200), and per-LUE roadway and water/wastewater impact fees are billed separately and can far exceed it.
- Trades are separate: Round Rock prices standalone electrical, HVAC, plumbing, gas-test, and irrigation permits at $50 each, on top of the building permit.
- No percentage surcharge: there is no add-on percentage and Texas has no statewide levy - the flat fee is the fee.
- No verified remodel or addition figure: the department's method for remodel, finish-out, and addition permits is in transition, so no dollar amount is printed here - call 512-218-5428.
- Source-currency caveat: the live fee pages carry no printed effective date; the only dated companion PDF is "Updated August 2023" - verify before relying on any figure.
Practitioner Insight
Round Rock has one of the simplest permit-fee structures in the Austin metro: a flat $485 for a new home at any size with plan review bundled, and a short menu of flat fees for everything else. That is a very different structure from Austin, where a new home runs closer to $1,842 all-in once tiered plan-review and inspection fees stack up, and from San Marcos to the south (a per-square-foot rate plus a flat technology fee) or Georgetown ($0.50/sq ft plus fixed fees). If you only need a deck, pool, shed, or solar permit, the flat fee is the whole story.
Two things trip people up. First, the $485 covers the permit, not the utility and impact charges - on a new home, the water meter ($320), water/sewer line ($200), and per-LUE impact fees (post-January-2024 plats: $4,912 water and $2,921 wastewater per LUE) can dwarf the permit itself, so price those early. Second, remodel, finish-out, and addition pricing is in transition: an older August 2023 PDF used a tiered valuation table while the current live pages list flat fees for many project types, so we do not print a verified remodel figure - call the Building Inspection Division at 512-218-5428. And because the live pages carry no printed effective date, confirm any figure by phone before budgeting.

When This Estimate May Not Apply
Your project is a remodel, finish-out, or addition
Round Rock's pricing method for those project types is in transition - an older August 2023 PDF used a tiered valuation table while the current live pages list flat fees for many project types - so no remodel or addition dollar amount is printed here. Call the department at 512-218-5428 for a quote.
Your project triggers separate utility or impact charges
The water meter ($320), water/sewer line ($200), roadway impact, and water/wastewater impact fees (post-January-2024 plats: $4,912 per LUE water, $2,921 per LUE wastewater) are all billed outside the building permit fee and can far exceed it.
Work began before the permit was issued
The department doubles the fee when work begins before a permit is issued.
The same inspection type fails twice
Two inspections of each type are included in a permit; once the same inspection type fails twice, a $75 re-inspection fee applies from the third inspection of that type.
The department revises its fee pages after our retrieval

Source note: All figures come from the Round Rock Building Inspection Division's published department fee pages (New Single-Family Construction, Standalone Building Permits, Other Building Permits), retrieved June 10, 2026. Those live pages carry no printed effective date (they reference the current 2024 codes), and the only dated companion document, the Planning & Development Fees Summary PDF, is marked "Updated August 2023" - we treat this as a source-currency caveat rather than a confirmation of age. The remodel/finish-out/addition valuation table from the August 2023 PDF is not reproduced here because the current pages appear to have replaced it with flat fees for many project types; that discrepancy is flagged for confirmation with the department.
