San Antonio Municipal Code Chapter 21 caps residential noise at 70 dB(A) day and 63 dB(A) overnight at the property line. SAPD can cite hosts and tenants, while repeat-call cost-recovery rules under Chapter 12 charge property owners for each follow-up response within 12 months.
San Antonio regulates parties through SAMC Chapter 21 (Health and Sanitation, noise article) plus Chapter 12 nuisance abatement provisions. Residential property must keep noise below 70 decibels (A-weighted) between 7 a.m. and 10 p.m. and 63 decibels overnight, measured at the property line. Amplified music plainly audible 100 feet from the source is also presumed unlawful. Texas Local Government Code Section 250.008 grants the city authority to enforce these limits. SAPD officers may issue citations to hosts, tenants, and property owners, and the third response within a 12-month period triggers SAMC cost-recovery billing for police time. Short-term-rental hosts face additional Type 2 STR permit consequences for repeat infractions. Bexar County municipal court hears appeals.
First citation is a Class C misdemeanor with fines up to $500. Repeat responses within 12 months trigger cost-recovery billing for SAPD time, can stack as nuisance abatement under Chapter 12, and may revoke STR permits.
