Quiet hours in Scottsdale, AZ — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Scottsdale enforces some of Arizona's strictest noise regulations under Chapter 19, Article II (Special Noise Violations). Noise above 68 dB(A) or 70 dB(C) between 10 PM and 9 AM creates a rebuttable presumption of violation. Habitual offenders face Class 1 misdemeanor charges with fines up to $20,000.
Scottsdale Revised Code Chapter 19, Article II governs special noise violations. Section 19-24 establishes the purpose of protecting residential tranquility. Noise is measured on the A-weighted scale with a Type 1 sound-level meter per ANSI S 1.4-1971 (Sec. 19-27). Between 10 PM and 9 AM, noise levels exceeding 68 dB(A) or 70 dB(C) create a rebuttable presumption of excessive noise. Chapter 18, Article VIII addresses nuisance parties and unlawful gatherings with the same decibel thresholds. Section 19-30 designates habitual offenders (three or more violations within 24 months) subject to Class 1 misdemeanor charges with fines of $10,000 to $20,000. The Old Town entertainment district has additional monitoring. Scottsdale's 2024 ordinance amendments strengthened enforcement tools for nuisance gatherings at STR properties.
Civil violation for first offense. Habitual offender (3+ violations in 24 months): Class 1 misdemeanor, $10,000-$20,000 fine. State law ARS 13-2916 also applies: up to $2,500 plus 6 months jail.
