This is not one of those rules that cities tend to ignore. San Antonio actively enforces its construction hours requirements.
Aircraft Noise
San Antonio hosts five military installations (JBSA-Lackland, JBSA-Randolph, JBSA-Fort Sam Houston, Camp Bullis, and Camp Stanley), making military aircraft noise a major land-use concern.

This is not one of those rules that cities tend to ignore. San Antonio actively enforces its aircraft noise requirements.
