How Delano Handles Noise Ordinances: A Practical Guide

Delano maintains 72 local ordinances across all categories, and 7 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Delano falls on the strict-to-permissive spectrum compared to other cities.

Amplified Music & Events

Delano relies on California Penal Code §415(2) (disturbing the peace by loud and unreasonable noise) and the City's CNEL-based noise standards under DMC §20.10.180 to address amplified music complaints.

Key details: State Authority: California Penal Code §415(2). Local Standard: Delano DC §20.10.180 (65 dB(A) CNEL exterior).

Penal Code §415 is a misdemeanor or infraction at the officer's discretion; the standard fine is up to $400 plus court costs. Equipment may be impounded if used to commit the violation.

Quiet Hours

Delano regulates noise through the Development Code's noise hazard provisions (DMC §20.10.180), which apply standards drawn from the General Plan Noise Element to any property within the 65 dB CNEL noise contour.

Key details: Code: Delano Municipal Code §20.10.180. Residential Exterior Cap: 65 dB(A) CNEL. Residential Interior Cap: 45 dB(A) CNEL. Enforced By: Delano Code Enforcement / DPD.

Noise above the CNEL standards constitutes a nuisance enforceable by Delano Code Enforcement and the Delano Police Department. Mitigation measures (sound walls, building shell upgrades) may be required as a condition of any project approval.

Vehicle Noise

Vehicle exhaust and stereo noise within Delano city limits are enforced under California Vehicle Code §§27150–27151 (muffler/exhaust modification) and §27007 (sound amplification audible at 50 feet), with Delano PD handling field enforcement.

Key details: Statewide Code: CVC §§27007, 27150–27151. Enforced By: Delano Police Department / CHP.

Correctable equipment violation with base fine plus assessments; SAE J1169 noise testing may be ordered.

Construction Hours

Delano's grading ordinance (DMC §20.10.100) authorizes the City to impose limits on the periods during which grading and earthmoving operations may occur, and construction noise is captured by the same 65 dB(A) CNEL exterior standard that protects residential neighborhoods.

Key details: Grading Code: Delano Municipal Code §20.10.100. Exterior Noise Cap: 65 dB(A) CNEL. Dust Rule: SJVAPCD Rule 8021.

Construction outside the authorized hours can trigger a stop-work order, building permit suspension, and code-enforcement citations. Repeated violations may delay final inspection or certificate of occupancy.

Barking Dogs

Animal noise complaints are handled under Delano Municipal Code Title 8 (Animals) and the Delano Police Department's Animal Control policy. Kern County Animal Services provides field response under contract.

Key details: Code Title: Delano Municipal Code Title 8 (Animals). Enforced By: Kern County Animal Services / DPD. Animal Control Policy: Delano PD Policy 811.

Citations under the City's general code enforcement process; continued violations may escalate to misdemeanor charges and impoundment if the dog is also unlicensed or at-large.

Industrial Noise

Delano Development Code §20.10.90.2.b requires walls for screening commercial and industrial activities and for sound attenuation as a condition of approval for adjacent commercial or industrial development.

Key details: Code: Delano DC §20.10.90.2.b–c. Min Wall Height: 6 ft (commercial side). Front/Street-Side: Reduced to 40 inches.

Project conditions of approval may withhold building permits or certificates of occupancy until attenuation walls are installed and tested.

Leaf Blower Rules

Delano has not adopted a specific leaf-blower ordinance. Use of gas-powered leaf blowers is regulated through the 65 dB(A) CNEL noise standard (DC §20.10.180) and CARB's small off-road engine (SORE) rule, which prohibited sales of new gas leaf blowers statewide in 2024.

Key details: State Rule: CARB SORE (AB 1346, 2021). New Gas Ban: January 1, 2024. Local Standard: DC §20.10.180.

Noise complaints handled via city code enforcement under the CNEL standard.

The Bottom Line

Delano'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 Delano is broadly strict or permissive.

Keep in mind that Delano can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
