Full Breakdown
San Antonio relies on voluntary programs rather than a mandatory green building code. Build San Antonio Green, a nonprofit certification program established in 2002, rates new homes against energy, water, indoor air quality, and materials criteria. CPS Energy offers Casa Verde and commercial Demand Response rebates for ENERGY STAR equipment, weatherization, and high-efficiency HVAC. Mandatory provisions appear in the SA Energy Code amendments to SAMC Chapter 10, requiring envelope insulation, efficient HVAC, and lighting controls aligned with IECC. City municipal buildings target LEED Silver under city policy. Some affordable-housing density bonuses and tax abatements reference Build San Antonio Green or LEED certification thresholds, creating market incentives.
Violations & Fines
Voluntary programs carry no penalties. Energy Code violations under SAMC Chapter 10 trigger permit holds and fines up to 2,000 dollars per day until corrected. Misrepresented certifications can void incentives and tax abatements.
