Construction hours in Tigard, OR — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Construction, demolition, and industrial activities are exempt from Tigard's general sound limits only between 7 a.m. and 8 p.m., seven days a week, under TMC 6.02.450 (Exceptions to Noise Limits). Outside that window, construction noise is treated as a noise nuisance under TMC 6.02 Article V. Even within the permitted hours, exempt activities cannot exceed 85 dB measured on a noise-sensitive property for more than five minutes in any calendar day.
Construction hours in Tigard are governed by the Exceptions to Noise Limits provision at TMC 6.02.450. Noise from construction, demolition, industrial, or agricultural activities is exempt from the general sound-limit rules of TMC 6.02 Article V only during the hours of 7 a.m. to 8 p.m., seven days a week. Tigard does not impose a shorter Sunday or holiday window — the same daytime hours apply every day. The exemption is not unlimited even during permitted hours: under the cap built into TMC 6.02.450, noise generated by an exempt activity that exceeds 85 dB measured on a property where a noise-sensitive use is located, for more than five minutes in any calendar day, remains a violation. Building permits for construction work are administered by the City of Tigard Building Division under the Oregon Residential Specialty Code and the Oregon Structural Specialty Code, but the permit itself does not override the noise exception window — work that runs past 8 p.m. is still subject to the general noise nuisance rules. Emergency work and equipment are separately exempt. Demolition with a city permit is treated under the same 7 a.m.-8 p.m. window unless a special permit is issued.
Construction noise outside the 7 a.m.-8 p.m. exemption window is enforced under TMC 6.02 Article V as a noise nuisance. Tigard Code Compliance typically issues a courtesy notice and seeks a voluntary compliance agreement for a first complaint, escalating to a civil infraction citation for repeat or refused compliance. Violations of the 85 dB / 5-minute cap during permitted hours are likewise enforced under TMC 6.02.450. The two-witnesses-from-different-households evidence rule under TMC 6.02 applies unless a city officer personally observed the violation.
