Deck Permit Cost in San Marcos, TX (2026)
Residential deck permit fees for the City of San Marcos, Texas, pulled directly from the Development Fees schedule adopted by Resolution 2025-185R, effective October 1, 2025. San Marcos prices decks and patios at $0.53 per square foot plus the $15 technology fee applied to all permits - so a 200 sq ft deck is $121.00. Texas has no statewide permit levy and San Marcos adds no percentage surcharge. Unlike flat-fee cities, the San Marcos deck fee scales with the size of the deck you build.
This guide covers: City of San Marcos, Texas (Hays County) residential deck and patio permit fees as published on the Development Fees schedule (Resolution 2025-185R) effective October 1, 2025. The schedule prints one line for "Decks/Patios" at $0.53 per square foot, and every permit adds the $15.00 technology fee printed at the top of the schedule.
Deck electrical is a separate permit: if your deck adds lighting, an outlet circuit, or a hot-tub feed, that is trade work priced on its own line - a residential stand-alone electrical permit is $63.00 plus the $15 technology fee ($78.00 all-in). A deck with no new electrical work needs no trade permit.
Deposit mechanics: San Marcos collects a non-refundable application deposit of one-half the permit fee (max $2,000) up front and credits it to the permit balance. On a $121 deck permit that is about $60.50 at application - it changes when you pay, not the total.
This guide does NOT cover: deck construction cost, HOA approvals, zoning setback questions, or whether a low free-standing deck under a code exemption threshold needs a permit at all - the schedule does not print exemption thresholds, so route that question to the Permit Center at (512) 805-2630 before filing.
A San Marcos, TX deck permit is $0.53 per square foot plus a $15 technology fee - $121.00 for a 200 sq ft deck and $174.00 for a 300 sq ft deck. Electrical work on the deck is a separate trade permit ($78 all-in). Texas adds no state levy. Figures are from the schedule effective October 1, 2025 - confirm at (512) 805-2630.
- San Marcos prices decks by size: $0.53 per square foot plus the $15 technology fee. A 100 sq ft deck is $68, a 200 sq ft deck is $121, a 300 sq ft deck is $174, and a 400 sq ft deck is $227.
- The deck line also covers patios - the schedule prints one "Decks/Patios" rate, so a covered patio slab and a raised wood deck are priced the same way per square foot.
- Deck electrical (lighting, outlets, hot-tub circuits) is a separate residential stand-alone electrical permit at $63 + $15 tech = $78.00 all-in. A no-electrical deck pays only the per-square-foot fee.
- Texas has no statewide percentage permit levy - unlike Virginia's 2% USBC add-on - and San Marcos adds no city percentage surcharge, just the flat $15 technology fee per permit.
- For context among verified Texas cities: a 200 sq ft deck is $121 in San Marcos versus $170 in Georgetown ($60 app + $0.50/sq ft + $10 tech) and $125 flat in Round Rock. San Marcos is cheaper than Round Rock for decks under about 208 sq ft, and pricier above that.
- The figures come from the current, dated schedule (Resolution 2025-185R, effective October 1, 2025, re-confirmed on the city's Fee Schedule page July 4, 2026). Work started without a permit is charged double.
San Marcos Deck Permit Fee Structure
The deck fee has two parts: the per-square-foot permit fee and the flat technology fee. The only common add-on is a separate electrical trade permit if the deck adds wired features.
| Item | Permit Fee | How It Is Calculated |
|---|---|---|
| Deck / patio permit | $0.53 / sq ft | Deck square footage x $0.53, from the "Decks/Patios" line on the schedule. |
| Technology fee | $15.00 | Flat, applied to all permits - printed at the top of the schedule. |
| 200 sq ft deck (typical) | $121.00 | (200 x $0.53) + $15. |
| Deck electrical (if added) | $78.00 | Residential stand-alone electrical trade permit $63 + $15 tech. Only if the deck adds wired features. |
| Application deposit | 1/2 of permit fee | Non-refundable, max $2,000, paid up front and credited to the permit balance - not an extra charge. |
| Re-inspection | $263.00 | Per occurrence, if an inspection must be repeated. |
| State / city percentage levy | None | Texas has no statewide permit levy; San Marcos adds no percentage surcharge. |
Source: City of San Marcos Development Fees schedule, Resolution 2025-185R, effective October 1, 2025. The schedule prints the rate as "$.53 cents per square foot" - the dollar-sign form controls, read as $0.53/sq ft. Confirm how your deck package is filed with the Permit Center at (512) 805-2630.
Worked Examples - Real Deck Projects in San Marcos
Every figure is direct arithmetic from the published schedule: square footage x $0.53, plus the $15 technology fee, plus a $78 electrical trade permit only when the deck adds wired features.
A homeowner builds a 200 sq ft attached wood deck with no lighting or outlet circuits.
- Deck permit: 200 x $0.53 = $106.00
- Technology fee: $15.00
- Texas state levy: $0.00 (none)
- Total deck permit: $121.00
About $60.50 of that is paid up front as the application deposit and credited at issuance.
A larger 300 sq ft deck adds a new outdoor lighting and outlet circuit.
- Deck permit: 300 x $0.53 = $159.00 + $15 tech = $174.00
- Electrical trade permit: $63 + $15 tech = $78.00
- Total: $252.00
The electrical line applies only when new wired features are added - whether it files as a stand-alone ($63) or child permit ($58) depends on how the job is pulled; the stand-alone figure is shown.
A small 100 sq ft entry deck or landing, no electrical.
- Deck permit: 100 x $0.53 = $53.00
- Technology fee: $15.00
- Total: $68.00
The schedule prints no minimum fee on the deck line, so the per-square-foot math governs even for small decks. Whether a very low free-standing deck is exempt from permitting is a code question for the Permit Center, not a fee-schedule line.
When This Estimate May Not Apply
The $0.53/sq ft + $15 figures cover the deck permit itself on the October 2025 schedule. Route your project to the Permit Center at (512) 805-2630 before relying on these figures if any of the following applies:
- Your deck adds electrical work. Lighting, outlets, or a hot-tub circuit is a separate trade permit - $63 stand-alone or $58 as a GC child permit, each plus $15 tech.
- Your project is really a covered porch or room addition. A roofed, enclosed structure may be classified as an addition at $0.63/sq ft rather than a deck at $0.53/sq ft - classification is the Permit Center's call.
- Your deck may be exempt. Some codes exempt low, small, free-standing decks from permits. The San Marcos schedule does not print exemption thresholds, so this page does not state one - ask before assuming a permit is or is not required.
- An inspection fails. A re-inspection is $263 per occurrence, and resubmittals after the second staff review are $315 each.
- You started work without a permit. The schedule doubles the normal fee ($200 flat for a homeowner's own work).
- The city adopts a new fee resolution. Fees were set by Resolution 2025-185R (effective October 1, 2025) and can change - confirm before filing.
Impact and tap fees do not apply to a residential deck, but the page-standard disclaimer still applies - always verify with the San Marcos Permit Center before budgeting.
San Marcos Deck Permit Cost vs Other Verified Texas Cities
San Marcos, Georgetown, and Round Rock all sit on the I-35 corridor through the Austin metro, and each prices a deck differently - per square foot, per square foot plus fixed fees, and flat. The comparison below uses a 200 sq ft deck.
| City | Deck Fee Basis | 200 sq ft Deck Permit |
|---|---|---|
| San Marcos, TX | $0.53/sq ft + $15 tech | $121.00 |
| Round Rock, TX | $125 flat (accessory/misc line) | $125.00 |
| Georgetown, TX | $60 app + $0.50/sq ft + $10 tech | $170.00 |
| Killeen, TX | $0.20/sq ft new-construction rate class, $200 min applies to the residential permit | Route to department |
San Marcos beats neighboring Round Rock on decks under about 208 sq ft ($0.53x + $15 crosses $125 at ~207.5 sq ft) and beats Georgetown at every realistic deck size up to about 490 sq ft. Killeen's schedule does not print a dedicated deck line, so it routes to the department rather than being estimated here. All figures are the deck permit only - electrical is separate in every listed city.
