Full Breakdown
Placentia Municipal Code § 23.81.170 sets two separate hour limits, one for grading and one for construction and maintenance.
Grading is permitted only between seven a.m. and seven p.m. Monday through Friday and between nine a.m. and six p.m. on Saturday. It is prohibited at any time on Sunday and on all federal holidays. The only exception is a different set of hours approved by the chief building official or city engineer on evidence that an emergency exists which would constitute a hazard to persons or property.
Construction activities and the maintenance of real property are governed by a three-column table. Initial construction runs 7:00 a.m. to 7:00 p.m. Monday through Friday and 9:00 a.m. to 6:00 p.m. on Saturday, and is prohibited on Sunday and holidays. Remodeling and repair work runs the same weekday and Saturday hours, with 10:00 a.m. to 5:00 p.m. allowed on Sundays and holidays. Maintenance of real property follows the remodeling schedule exactly.
The code defines the categories. Initial construction means new residential, commercial and industrial developments built on vacant property, which require planning commission approval and, in particular cases, city council approval. Remodeling and repair covers work where structures already exist, including structural additions, rehabilitation, re-roofing and swimming pool construction, projects that require over-the-counter permit approval only. Maintenance of real property includes mowing lawns, trimming trees and shrubs and general landscape maintenance.
The noise chapter points back to this section. Under § 23.76.070(8), noise from grading, construction and maintenance is not subject to the decibel limits of Chapter 23.76, but those activities are prohibited at all times other than the hours in § 23.81.170. A homeowner re-roofing in the City of Placentia, Orange County, California, therefore has a Sunday window that a developer pouring a new tract does not.
Violations & Fines
Section 23.81.170 prints no penalty of its own. Under Placentia Municipal Code § 1.10.030, an enforcement officer can issue an administrative citation for any code violation. Where the city council has set no amount by resolution, fines are capped at $100 for a first violation, $200 for a second within one year, and $500 for each additional violation within one year, and each day is a separate offense. The 30-day late payment penalty is 50 percent of the fine.
