How Lynnwood Handles Noise Ordinances: A Practical Guide

Lynnwood maintains 26 local ordinances across all categories, and 4 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Lynnwood falls on the strict-to-permissive spectrum compared to other cities.

Aircraft Noise

Lynnwood does not have a local airport. Paine Field (PAE) in Everett is approximately 5 miles northeast. Aircraft noise is regulated federally by the FAA. No local aircraft noise ordinance exists.

Key details: Local Airport: None in city limits. Nearest Airport: Paine Field PAE (~5 mi NE in Everett). Regulation: FAA (federal). Local Code: None.

New construction without required sound insulation in airport zones carries stop-work orders and fines of $500–$2,000. Failure to provide real estate noise disclosure results in liability for rescission of sale.

If you are coming from a city with tighter rules, you will find Lynnwood gives residents more flexibility on aircraft noise.

Quiet Hours

Lynnwood noise regulations are governed by LMC Ch. 10.12, which adopts WAC 173-60 Environmental Designation for Noise Abatement (EDNA) standards. Quiet hours apply between 10 p.m. and 7 a.m., during which noise limits for residential (Class A EDNA) areas are reduced by 10 dBA. Yelling, shouting, or loud singing between 10 p.m. and 7 a.m. is prohibited (LMC §10.12.300).

Key details: Quiet Hours: 10 p.m.–7 a.m.. Nighttime Reduction: 10 dBA lower than daytime (Class A EDNA). Code: LMC Ch. 10.12; WAC 173-60. Prohibited: Yelling/shouting between 10 p.m.–7 a.m..

Quiet-hours violations are infractions with fines of $100 for a first offense, $250 for a second offense within 12 months, and up to $500 for subsequent offenses. Repeat violations may result in misdemeanor charges.

Barking Dogs

Barking dogs that cause a noise disturbance are subject to LMC §10.12.300 (noises prohibited). Noise audible at 50 feet from the source is prima facie evidence of a violation. Animal control handles chronic barking complaints; contact the Lynnwood Police Department animal control unit.

Key details: Standard: Audible at 50 ft = prima facie violation. Code: LMC §10.12.300. Enforcement: Animal control / police. Contact: Lynnwood Police Dept..

First offense results in a written warning. Second offense within 12 months carries a $75 fine. Third and subsequent offenses are $150–$300. Chronic cases may result in animal impoundment.

Construction Hours

Construction noise in Lynnwood is limited to Monday through Friday between 7 a.m. and 6 p.m. under LMC §10.12.300. Weekend construction is prohibited unless specifically approved by the city. Construction outside permitted hours must receive special authorization from the Community Development Department.

Key details: Weekday Hours: 7 a.m.–6 p.m., Monday–Friday. Weekends: Prohibited unless approved. Code: LMC §10.12.300. After-Hours Approval: Community Development Dept..

Construction outside permitted hours carries fines of $250 for a first offense, $500 for a second, and up to $1,000 for subsequent violations. Stop-work orders may be issued for repeat offenders.

Compared to other cities, Lynnwood takes a harder line on construction hours. The enforcement and penalty structure reflects that.

The Bottom Line

Lynnwood's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lynnwood is broadly strict or permissive.

These rules come from Lynnwood's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
