San Leandro, CA Noise Ordinances: Construction Hours (2026)

Section 4-1-1115(b) of San Leandro's Noise Ordinance restricts construction and related activity that is adjacent to, or across a street or right-of-way from, a residential use. m. on Saturday and Sunday; no construction of any kind is allowed on federal holidays. The ordinance defines 'construction' broadly to reach site preparation, assembly, erection, substantial repair, alteration and demolition on private property as well as on public or private rights-of-way, streets, structures, utilities and facilities, so the hour limits cover everything from framing a new house to trenching a utility line in the street.

Because the restriction is keyed to proximity to a residential use rather than to a construction permit type, it applies equally to owner-occupied remodels, commercial builds next to housing, and City-let public works projects along a residential block. Enforcement runs through Section 4-1-1130, which treats a violation as a public nuisance abated under Chapter 1-12, but Section 4-1-1115(b) also gives the City two construction-specific tools: a stop-work order that halts the job on the spot, and revocation of any or all permits issued for the project.

Those remedies apply on top of, not instead of, the general noise-nuisance process, so a contractor working outside the permitted hours can face both a stop-work order and a nuisance citation for the same incident. The rule sits within the 2024 update to the Noise Ordinance, Ordinance No. 2024-012, which reenacted Sections 4-1-1100 through 4-1-1130 in their current form.
