What we assumed
We price HVAC replacement in San Antonio, TX at 3-ton (36,000 BTU) like-for-like split system.
For the permit line we assumed the official existing-residential mechanical base plus per-device lines, plus the 4% Technological Improvement and 4% Development Services surcharges on each band. The low fee is $69.87 (one replacement device: $57.50 + $7.19, plus surcharges), the typical fee is $81.79 (3-ton like-for-like furnace plus AC: $57.50 + $11.04 + $7.19, plus two $3.03 surcharges), and the high fee is $89.56 (adds an air handler at $7.19, plus surcharges). The high is not a second fee stacked on top of the typical. The §10-38 valuation table and the $88.55 new-system line are not the official typical path. A separate electrical permit if a new circuit is not in these totals. Full arithmetic is in the calculation note on this page. Listed valuations of $5,000, $7,500, and $16,000 are unused. The official typical project value is $7,500.

The schedule says that unless noted, all fees are subject to a 4% Technological Improvement surcharge and a 4% Development Services surcharge; the lines used here are not noted as exempt, so both are added, each rounded to the cent (the city invoice may differ by a cent). The $11.50 convenience fee for staff-processed applications and the 3% card fee are not added; inspection scheduling is free online. Separate electrical permit if a new circuit.
City of San Antonio DSD FY 2027 Development Fee Schedule, revised September 2026 (source retrieved 2026-10-07). The official typical path is a 3-ton like-for-like furnace plus AC on the existing-residential mechanical inspection fees on PDF page 15. The Mechanical Permit Base Fee is $57.50, a gas furnace is $11.04 each, and a condensing unit, heat pump, air handler, or replacement device is $7.19 each. Each line is fixed by the schedule, and a permit is required on this path. The schedule says that unless noted, all fees are subject to a 4% Technological Improvement surcharge and a 4% Development Services surcharge, and these lines are not noted as exempt, so both are added. Low $5,000, one replacement device: $57.50 + $7.19 = $64.69; 4% is $2.59, so $64.69 + $2.59 + $2.59 = $69.87. Typical $7,500, furnace plus condensing unit: $57.50 + $11.04 + $7.19 = $75.73; 4% is $3.03, so $75.73 + $3.03 + $3.03 = $81.79. High $16,000 adds an air handler: $75.73 + $7.19 = $82.92; 4% is $3.32, so $82.92 + $3.32 + $3.32 = $89.56. The low, typical, and high fees are $69.87, $81.79, and $89.56, and the high is not a second fee stacked on the typical. The official typical project value is $7,500; valuation is not an input on these inspection fees. The $88.55 existing-residential new-system line applies only when there is no pre-existing central unit and is not this change-out path. A separate electrical permit applies if a new circuit is needed and is not counted. Before October 2026 this row used FY2026 lines of $50, $9.60, and $6.25 with no surcharge.
