Opening a Gym in San Antonio, Texas
San Antonio is one of the strongest gym markets in Texas — and one of the most underserved relative to its size. The city is the 7th largest in the United States with over 1.5 million residents, growing by nearly 24,000 people per year, and projected to surpass Philadelphia as the 6th largest city by 2026. The median age is 34.4 — well below the national average of 38.9 — putting the prime gym demographic (ages 25–44, roughly 460,000 people) at the center of the population.
What separates San Antonio from every other major Texas city is the military. Joint Base San Antonio (JBSA) is the largest joint base in the U.S. military, with 67,350 direct employees, 32,333 active-duty service members, 29,610 dependents, and over 173,000 indirect jobs — a combined economic footprint of $55 billion annually. Active-duty personnel maintain mandatory fitness standards, and that culture radiates outward to families, retirees, veterans, and the 19,000+ USAA employees headquartered here. Military City, USA is not a slogan — it is a market reality that shapes pricing, programming, and location strategy for every gym in the metro.
The cost structure favors operators. Average retail rent runs $19.16/SF NNN metro-wide — roughly 20–45% below Austin and 15–25% below Dallas. CPS Energy, the nation's largest municipally owned electric and gas utility, delivers bundled commercial electricity at approximately 9–12.5 cents/kWh with no rate increases in the current FY2027 budget cycle. You cannot choose an alternative provider, but you also will not face ERCOT price spikes or the complexity of shopping for a Retail Electric Provider. SAWS water and sewer rates are tiered and predictable. Total startup costs for a mid-size gym range from $209,000 to $1,050,000, meaningfully below comparable builds in Austin or Dallas.
San Antonio's extreme summer heat — 75 days above 100 degrees in 2023, with humidity compounding the danger — is not a liability. It is a demand driver. From May through October, outdoor exercise becomes unsafe, and indoor fitness is not optional. Budget for oversized HVAC systems and expect summer electric bills 40–60% above winter baseline, but recognize that those five to six months of extreme heat represent peak membership growth and the highest utilization your facility will see all year.
