Top 10 Code Violations

The San Dimas Code Compliance Division has identified the top 10 most common violations in an effort to help our residents understand how to promote and maintain a quality living environment.

Overnight Street Parking without Permit

The City of San Dimas has a prohibition on parking on all City streets between the hours of 2:00 am and 5:00 am, pursuant to Municipal Code Section 10.24.010, except with an annual or temporary overnight parking permits. This ban not only improves the aesthetics of the community, but it also allows for the greater public safety of the area.

RVs Parking in Front Yard

RVs, trailers, boats, and camper shells are not allowed to be parked in front yard driveway. They must be parked in the side or rear yard, and behind the main building line of the house.

Property Maintenance

Weeds, overgrown grass, or plants obstructing public sidewalk or street are unsightly, can create fire hazards, and act as rodent habitat. Dumping of trash, debris, and dirt is unsightly, threatens the environment and water supply, acts as rodent habitat, and poses a threat to the community’s health, safety, welfare, and property values. Structures and fences that are not maintained properly are unsightly, and pose health and safety risks, and can negatively affect neighborhood property values.

Trash Cans

Trash cans put out too early or left out too late are unsightly and create parking problems. Trash cans shall not be placed out earlier than 3:00 pm on Monday and shall be removed by 7:00 pm on Tuesday (the day of collection). Trash cans must be stored out of view from the public right-of-way.

Inoperative Vehicle

“Inoperative Vehicle” means any vehicle which is not capable of driving under their own power, or which lacks wheels, tires, doors, windshield, or lacks current DMV registration tags.

Abandoned Vehicle

Vehicles that have been abandoned, wrecked, dismantled, or inoperative are considered “abandoned vehicles.”

Vehicle Parked on Unpaved Surface

Vehicles must be parked on a paved surface.

Building without a Permit

Construction or demolition without a building permit poses a threat to public health and safety. Most property improvements, or changes to existing structures or grades, require permits to ensure the projects are built to meet the required safety codes. The permit and inspection process helps protect the homeowner’s property value. To apply for a building permit, contact the Building and Safety Division at 909.394.6260.

Illegal Signs

Signs installed without a permit can be unsightly or pose a threat to public safety and property values.

Tree Removal without a Permit

Removal of mature trees requires a City permit and replacement of the trees. To apply for a tree removal permit, contact the Planning Division at 909.394.6250.
