Noise from Specific Sources in Springfield, MO: What Residents Actually Need to Know
If you live in Springfield or are thinking about moving there, noise from specific sources are one of those things you probably won't think about until they affect you directly. Springfield has 4 specific rules on the books covering different aspects of noise from specific sources, and some of them might surprise you.
Low-Frequency Bass Limits
Springfield bans running any amplified sound system between 11:00 p.m. and 7:00 a.m. if the bass or other sound carries 50 feet or more from the speakers.
Key details: Nighttime hours: 11:00 p.m. to 7:00 a.m.. Test: Audible 50+ feet from speakers. Governing section: City Code § 78-115(1)c. Also covers: Car stereos on public streets. Adopted: G.O. No. 6330, Jan. 2017.
A violation of § 78-115(1)c is a City Code offense punishable under the general penalty provision, § 1-7; officers use the 50-foot plainly-audible test to establish the violation.
Generator Noise
Springfield exempts emergency electric generators, along with safety signals and pressure-relief valves, from the Land Development Code's noise standard, so generator noise itself isn't capped or restricted by the zoning code.
Key details: Governing section: LDC § 36-485(3)(c)1.c. Exempt use: emergency electric generators. Also exempt: safety signals, pressure relief valves. Applies: citywide, all zoning districts.
Not applicable: generator noise covered by this exemption isn't a code violation regardless of volume, since § 36-485 excludes it from the sound level standards.
Springfield is more permissive than most cities when it comes to generator noise. That said, there are still limits.
Delivery Truck Noise
Springfield bans loud, excessive noise from loading or unloading vehicles and from breaking down boxes, crates, and containers: the provision that covers delivery truck noise citywide.
Key details: Citation: § 78-113(4), Division 2 Noise. Covers: Loading, unloading, container noise. Scope: Citywide, not district-limited. Penalty: Up to $1,000 fine or 180 days jail.
A violation is punishable under City Code § 1-7's general penalty: up to a $1,000 fine, up to 180 days in jail, or both, with each day a separate offense.
Bar & Nightclub Noise
Springfield's noise code bars bars, restaurants and other commercial developments from running amplified sound systems loud enough to unreasonably disturb nearby dwellings or businesses, including outdoor cafes tied to the venue.
Key details: Governing section: City Code § 78-115(1)a. Standard: Unreasonably disturbs nearby dwellings/businesses. Covers: Bars, businesses, outdoor cafes. Enforced by: Springfield Police Department. Adopted: G.O. No. 6330, Jan. 2017.
Violating § 78-115 is a City Code offense punishable under the general penalty section, § 1-7; the city may pursue municipal prosecution for repeated or ongoing sound-system disturbances.
The Bottom Line
Springfield's noise from specific sources 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 Springfield is broadly strict or permissive.
