Pool Permit Cost in San Marcos, TX (2026)
Residential swimming pool permit fees for the City of San Marcos, Texas (Hays County, between Austin and San Antonio on the I-35 corridor), pulled directly from the Development Fees schedule adopted as Resolution 2025-185R, effective October 1, 2025. San Marcos prices a swimming pool permit at a flat $263.00, and the schedule adds a $15.00 technology fee to every permit, so the building-side all-in is $278.00. Pool electrical and plumbing are separate trade permits. Texas has no statewide permit levy. This is the current fiscal-year schedule, so there is no source-age caution here.
This guide covers: The City of San Marcos swimming pool permit fee as printed in the current Development Fees schedule - a flat $263.00 pool permit plus the schedule's $15.00 technology fee applied to every permit, for $278.00 all-in on the building side. Both figures are exact from the schedule effective October 1, 2025.
This guide does NOT cover: pool construction cost, pool electrical (a separate residential stand-alone electrical permit, $63.00), pool plumbing (a separate residential stand-alone plumbing permit, $63.00), gas heater lines, a required pool safety barrier or fence (the San Marcos fence permit is $79.00 + $15 tech), engineering, or impact/utility fees. The schedule also charges an application deposit of one-half of the permit fee up front, which is applied to the permit balance (not an additional charge). These items are separate from the $278.00 building-side all-in.
A residential swimming pool permit in San Marcos, TX is a flat $263.00, plus the schedule's $15.00 per-permit technology fee, for $278.00 all-in on the building side. Pool electrical and plumbing are separate residential trade permits at $63.00 each. Texas adds no statewide levy, and an application deposit of half the permit fee is applied to the balance rather than added on top. This figure comes from the Development Fees schedule (Resolution 2025-185R, effective October 1, 2025). Verify with San Marcos Development Services (512-393-8000) before filing.
- San Marcos charges a flat $263.00 for a residential swimming pool permit - a single flat line, not a valuation-based fee.
- The schedule adds a $15.00 technology fee to every permit, so the building-side all-in is $278.00.
- Pool electrical and plumbing are separate residential stand-alone trade permits at $63.00 each - not folded into the $278.00 building-side figure. A full pool project therefore commonly runs higher once trades are added.
- Texas requires a compliant safety barrier around a residential pool; the San Marcos fence permit is a separate $79.00 (+$15 tech) line, not included in the pool permit.
- Among verified Texas cities, San Marcos's $263 pool permit is on the higher side - above Grand Prairie's $100, Tyler's $150, El Paso's $160, Abilene's $180 and Frisco's $200, and below Denton's $378.
- The figures come from the San Marcos Development Fees schedule (Resolution 2025-185R, effective October 1, 2025) - the current schedule. Verify before relying on them.

Worked Examples - Real Pool Projects in San Marcos
The pool permit is a flat building-side fee; trade permits are added when the pool needs electrical or plumbing work. The examples below use the current schedule amounts.
A homeowner pulls just the pool building permit (trades filed separately by subcontractors).
- Swimming pool permit: $263.00
- Technology fee: $15.00
- Building-side permit: $278.00
This is the flat building-side figure only. Pool electrical and plumbing are separate permits.
A typical in-ground pool with pump/equipment wiring and plumbing, all pulled by the homeowner or a single contractor.
- Building-side permit: $278.00
- Pool electrical: $63.00
- Pool plumbing: $63.00
- Estimated total: $404.00
The $404.00 is a build-up estimate assuming both trades are pulled as residential stand-alone permits. Trade counts and whether a child-permit rate applies under a general contractor can change it - confirm with Development Services.
The homeowner submits the pool application and pays the deposit up front.
- Deposit at submittal: 1/2 of $263.00 = $131.50
- Balance at issuance (incl. tech fee): $146.50
- Building-side total: $278.00
The deposit is applied to the total, not added on top - the building-side permit is still $278.00. Confirm deposit and refund handling with Development Services.
When This Estimate May Not Apply
The $278.00 building-side all-in ($263.00 pool line + $15.00 technology fee) covers the pool building permit on San Marcos's current schedule. Route your project to San Marcos Development Services before relying on this figure if any of the following applies:
- The pool needs electrical or plumbing permits. Those are separate residential stand-alone trade permits at $63.00 each and are not in the $278.00 building-side figure.
- A safety barrier or fence is required. Texas requires a compliant barrier around a residential pool; the San Marcos fence permit is a separate $79.00 (+$15 tech) line.
- A gas heater is added. Gas line work is a separate plumbing/gas permit not covered by the pool building permit.
- Impact, utility, or engineering fees apply. Those are assessed separately from the building permit.
- The property is commercial or a community pool. Commercial pools are priced on different parts of the schedule, not the flat residential pool line.
- The schedule changes. San Marcos adopts a new fee resolution periodically; confirm the current amount before budgeting a later job.
Pool electrical and plumbing permits, a safety barrier/fence, gas-heater lines, impact/utility/engineering fees, and commercial pools are all excluded from the $278.00 building-side pool permit on this page, and the page-standard disclaimer applies - always verify with San Marcos Development Services before budgeting.
