Where to file in Loudoun County
For noise you can hear inside your home with the doors and windows closed, call the Loudoun County Sheriff's Office non-emergency line, 703-777-1021, while the noise is occurring, and 911 for an emergency. The County's Loudoun Express Request (LEx) page says such complaints "should be submitted directly to the Loudoun County Sheriff's Office when the noise is occurring by calling the non-emergency line at 703-777-1021." For recurring noise that is audible outside at your property line and may break the Zoning Ordinance's decibel limits (the County gives amplified music or voice and barking dogs at kennels as examples), report a zoning violation online through LEx. The County says initial review happens during normal county business hours, 8:30 a.m. to 5:00 p.m., Monday to Friday, and that once a complaint is submitted Zoning Enforcement can arrange inspections to measure the noise when it is occurring. Barking dogs: Loudoun County Animal Services says first-time complaints about barking dogs at a particular address can be made online through LEx, that all future complaints about the same address should be made by phone to 703-777-0406 while the barking is occurring, and that after hours complaints can be made by phone to 703-777-1021. Under § 612.19(a)(5) the complaint must be verified by an Animal Control Officer or a law-enforcement officer before a citation is issued, and a summons follows if, after notification by the investigating officer, the owner fails to correct the condition within a reasonable period of time. A resident may also apply to a Magistrate for a warrant (§ 654.02(f)(4)). Penalties: two sections of the code state the penalty for § 654.02 and they do not match. Under § 654.02(f)(1) a first offense is a Class 3 misdemeanor, a violation within six months after a previous conviction is a Class 2 misdemeanor, and a violation within one year of a previous conviction is a Class 1 misdemeanor. Section 654.99(a), the chapter's penalty section, says whoever violates § 654.02 is guilty of a Class 3 misdemeanor and is fined not more than $500 for each offense, with each day a separate offense; it has no higher class for a repeat offense. The code does not say which section controls. The Sheriff's Office page puts the range as "from a Class 3 misdemeanor, which carries a maximum fine of $500, to a Class 1 misdemeanor, which carries a maximum penalty of twelve months in jail and a $2,500 fine." The Board of Supervisors may also ask the circuit court for an injunction (§ 654.02(f)(3)). Animal noise under § 612.19(a) is a Class Four misdemeanor. For zoning noise, the County's data center noise page says that if a substantiated violation is not cured, zoning enforcement staff issue a Notice of Violation and then civil penalty fines. The Sheriff's Office pages list its office phone as 703-777-0407.

Before you call
- Log it. Date, start and end time, what the noise was and where you heard it from. Three dated entries carry more weight than one angry call.
- Measure it if you can. Loudoun County sets measured limits for some noise, so a reading can help, and a dated log counts either way. The free noise log runs in your browser, records nothing, and saves a dated report.
- Check the rule. Quiet hours in Loudoun County: No general quiet hours; lawn equipment and construction banned 9 p.m. to 7 a.m. The Loudoun County noise ordinance page quotes the code verbatim, so you can cite the section.
- Try the source once. A neighbour, landlord or venue manager often fixes it faster than the county does, and telling them first strengthens a later complaint.
What happens after you file
Noise reports often wait behind urgent calls, so a first call may not end the noise that night. What it does is start a record against the address. Repeated reports, a dated log and a reading are what move a case from a warning to a citation. Where the county needs an officer to witness the noise, as most audibility rules require, file while it is happening rather than the next morning.
