TX - 2027
Pool & outdoor living in Texas
In-Ground Gunite pools (<400 sq ft) in Texas typically carry engineering costs of $2,600–$4,150, with a shell thickness of 6-8 in. and #4 rebar spaced 12 in. on center. The most common rejection reason for that pool type is: Missing bonding grid.
Pool Type | Pool Size sq ft | Gunite Shell Thickness in | Rebar Size | Rebar Spacing in OC | Bonding Grid Required | Typical Engineering Cost | Common Rejection Reason |
|---|---|---|---|---|---|---|---|
In-Ground Gunite | <400 | 6-8 | #4 | 12 | Yes (every 3 ft) | $2,600 - $4,150 | Missing bonding grid |
In-Ground Gunite | 400-800 | 8 | #5 | 10-12 | Yes (every 3 ft) | $3,650 - $5,700 | No soil compaction test |
Fiberglass | Any | Shell only | #3 ties | 18 | Yes | $1,870 - $3,120 | No cantilever coping detail |
Above-Ground | Any | N/A | N/A | N/A | Yes | $1,250 - $2,080 | No deck load calc |
Outdoor Kitchen/Patio Cover | Any | N/A | #4 or #5 | 12-18 | Yes if electrical | $2,080 - $3,650 | No wind uplift straps |
01
9th Edition FBC applies. Screen enclosures and outdoor structures need current product approvals and wind design. JRH handles full packages.
Updated 2027 • FBC 9th Edition • Wind load calcs and product approvals essential • Costs uplifted
Texas notes & assumptions
FL - 2027
Pool & outdoor living in Florida
In-Ground Gunite pools (<400 sq ft) in Florida typically carry engineering costs of $3,120–$4,680, with a shell thickness of 8 in. and #5 rebar spaced 10 in. on center. The most common rejection reason for that pool type is: Missing wind load calc.
Pool Type | Pool Size sq ft | Gunite Shell Thickness in | Rebar Size | Rebar Spacing in OC | Bonding Grid Required | Typical Engineering Cost | Common Rejection Reason |
|---|---|---|---|---|---|---|---|
In-Ground Gunite | <400 | 8 | #5 | 10 | Yes (equipotential) | $3,120 - $4,680 | Missing wind load calc |
In-Ground Gunite | 400-800 | 8-10 | #5 or #6 | 8-10 | Yes | $4,160 - $6,760 | No product approval for screen enclosure |
Fiberglass | Any | Shell only | #4 ties | 12-18 | Yes | $2,290 - $3,950 | No HVHZ wind design if applicable |
Above-Ground | Any | N/A | N/A | N/A | Yes | $1,560 - $2,600 | No barrier compliance |
Outdoor Kitchen/Patio Cover | Any | N/A | #5 | 10-12 | Yes | $2,600 - $4,680 | No impact-rated openings |
Updated 2027 • Engineering costs ~4% higher • Bonding and soil compaction still top rejection items
Florida notes & assumptions
01
Costs uplifted ~4% from 2026. Geotechnical report strongly recommended for expansive clays (common in TX).
NC - 2027
Pool & outdoor living in North Carolina
In-Ground Gunite pools (<400 sq ft) in North Carolina typically carry engineering costs of $2,290–$3,950, with a shell thickness of 6-8 in. and #4 rebar spaced 12 in. on center. The most common rejection reason for that pool type is: Missing equipotential bonding.
Pool Type | Pool Size sq ft | Gunite Shell Thickness in | Rebar Size | Rebar Spacing in OC | Bonding Grid Required | Typical Engineering Cost | Common Rejection Reason |
|---|---|---|---|---|---|---|---|
In-Ground Gunite | <400 | 6-8 | #4 | 12 | Yes (equipotential) | $2,290 - $3,950 | Missing equipotential bonding |
In-Ground Gunite | 400-800 | 8 | #5 | 10-12 | Yes | $3,330 - $5,400 | No frost footing depth |
Fiberglass | Any | Shell only | #3 ties | 18 | Yes | $1,665 - $2,910 | No backfill compaction spec |
Above-Ground | Any | N/A | N/A | N/A | Yes | $1,040 - $1,870 | No deck bracing |
Outdoor Kitchen/Patio Cover | Any | N/A | #4 | 12-18 | Yes if electrical | $1,870 - $3,330 | No snow load calc (mountain counties) |
Updated 2027 • Costs ~4% higher • Frost footing and equipotential bonding key items
Florida notes & assumptions
01
Frost depth critical in western NC. Equipotential bonding required. JRH provides sealed designs.
