Full Breakdown
Round Rock, Cedar Park, and Leander enforce construction start and stop times through city ordinances, but that authority stops at the city limit. On unincorporated land, no county rule bars weekend or dawn hammering. The only backstop is state disorderly-conduct law, which requires the noise to be genuinely unreasonable near a residence, a higher bar than a fixed 7 a.m. start. HOA construction rules, common in Austin-metro subdivisions, are frequently the real constraint on builders.
Violations & Fines
No construction-hour fine exists countywide. Persistently unreasonable noise near a home can draw a Class C disorderly-conduct citation and a fine up to $500 after a deputy gives notice.
