San Dimas Code Compliance takes concerns through the city’s MySanDimas reporting page or by phone at 909.394.6250, and describes its goal as voluntary compliance, with a contracted legal firm handling prosecution when voluntary compliance does not happen. This guide explains how San Dimas code compliance works, what kinds of problems the city lists, which phone numbers to use, and what to do about an open case if you want to sell.
The city’s page does not publish correction deadlines or a fine schedule for most violations, so ask for those in writing.

How the city says enforcement works
The Code Compliance page says that if you suspect violations of the San Dimas Municipal Code, you can report through MySanDimas or call 909.394.6250.
It asks for your name and phone number, which it says are kept strictly confidential, the street address or a description of the location, and whether you want an inspector to call you back.
The city states that its goal is voluntary compliance and that, when that does not occur, it contracts with a legal firm to provide prosecution services.
The page does not describe notice formats, correction deadlines or an appeal process. If you receive a notice, ask the inspector for the case number, the municipal code section cited, what counts as corrected, the compliance date and how to request a re-inspection.
Problems the city lists
The page lists these violation types: overnight street parking without a permit, RVs parked in the front yard, property maintenance (weeds, overgrown grass or plants obstructing the public sidewalk or street, dumping of trash, debris and dirt, and structures and fences not maintained properly), trash cans put out too early or left out too late, inoperative vehicles, abandoned vehicles, vehicles parked on an unpaved surface, building without a permit, illegal signs, and tree removal without a permit.
For someone preparing to sell, three entries matter most: property maintenance, building without a permit and vehicles on unpaved surfaces. An open complaint about unpermitted work can sit alongside a missing permit, so the two issues are often resolved together. Our San Dimas building permits guide and zoning and ADU guide cover that overlap.
Parking, RVs and trash cans
The city’s rules on everyday items trip up many owners. Trash cans may not be placed out earlier than 3:00 p.m. on Monday and must be removed by 7:00 p.m. on Tuesday, the collection day.
Parking on all city streets is prohibited from 2:00 a.m. to 5:00 a.m. unless you hold an overnight parking permit, and the city offers annual and temporary overnight permits.
The RV parking page states a penalty of $100 for a first violation of parking an RV in the front yard driveway without a permit, $200 for a second and $500 for a third. Overnight parking questions go to the Code Compliance Division at City Hall.
Who handles what
The Code Compliance page lists several outside agencies for related issues: Animal Control at 909.623.9777, the Los Angeles County Sheriff’s San Dimas Station at 909.450.2700, Los Angeles County Fire Department stations 64 and 141, the Los Angeles County Health Department for green pools at 626.813.3360, the San Gabriel Valley Mosquito and Vector Control District at 626.814.9466, the county Africanized Bee Program at 626.575.5466, and the California Department of Consumer Affairs Renter’s Hotline at 800.952.5210.
Building and Safety is 909.394.6260 and Planning is 909.394.6250. The page also notes that violations of private CC&Rs can be penalized as set out in the legal section of those regulations, which is separate from city enforcement.
Calling the wrong office is a common reason a complaint stalls, so confirm which agency issued the notice you hold.
Selling a San Dimas house with open code violations
An open notice or citation does not stop you from selling. California sellers generally disclose known notices on the Transfer Disclosure Statement, which asks about notices of abatement or citations against the property, and a title search will show any recorded lien. Our as-is and unpermitted work guide explains the disclosure rules, and the closing costs guide covers how liens and fees are paid at closing.
In practice, sellers with open violations usually choose one of three paths: correct the problem and ask the city to close the case before listing, disclose it and sell with a price adjustment, or sell as-is to a cash buyer who takes on the cleanup. Which one fits depends on how big the problem is, how much time you have and whether fines are still growing. Before you decide:
- Get the case number, notice date and the specific code sections cited.
- Ask the city what must be done to close the case and whether it will re-inspect.
- Ask for a current statement of fines, fees and any recorded liens.
- Get quotes for the work so you can compare repair cost with a no-repairs sale.
- Check whether tenants, an estate or a co-owner need to be part of the decision.
Questions to ask the San Dimas code enforcement team
- What exactly is the violation, and what would count as fixed?
- What is the deadline, and can it be extended if work is under way?
- Are fines accruing, and what is the total today?
- Has a lien or special assessment been recorded against the property?
- How do I request a re-inspection once the work is done?
Common mistakes homeowners make with violation notices
The costliest mistake is ignoring a notice. Deadlines for appeals are short, fines and fees can escalate, and unpaid costs can end up as a lien that follows the property.
Other common errors include fixing the problem but never asking for a re-inspection, assuming a tenant or relative dealt with a notice, and doing repair work that needs a permit without pulling one.
Keep every notice, photo and receipt, and write down the name of each staff member you speak with.
If the home came to you through an inheritance, a divorce or a tenant who left it in poor condition, the notice may land on you without warning. Our probate home sale guide and inherited home tax basis guide cover inherited property, and a no-repairs cash sale can be a practical way to close the file.
