Montclair businesses buy water from Monte Vista Water District, while the City of Montclair provides sewer service, and any work on City sewers needs a permit and a CSLB Class A contractor. The City's Building Department handles plumbing permits and inspections. Call the number on this page to be connected with a local plumber in Montclair.
Warning signs for Montclair businesses
- Brown or rusty water after the building sits closed over a weekend
- Low pressure at back-of-house sinks while the front is busy
- Repeated clogs in older restroom drains
- Pinhole leaks showing up as stains in ceilings or walls
- Sewer odor in a tenant space that has sat empty
- Water heaters short on hot water at peak hours
Utilities, sewer rules and permits
Montclair, about 30 miles east of Los Angeles in the Pomona Valley, was built out from citrus orchards after World War II, and its building stock shows it: the median home dates to 1969. The City itself advises having older properties checked for problems such as pipe corrosion or lead from old pipes. For commercial owners, aging galvanized supply lines and cast iron drains are common reasons to call.
Water and sewer come from separate agencies. MVWD starts water service and answers water quality and main water line questions at (909) 624-0035, then forwards new account information to the City for trash and sewer. Sewer is a City of Montclair service, and two City rules stand out: any work on City sewers requires a permit and a CSLB Class A contractor, and a property just outside city limits that wants Montclair sewer has to go through irrevocable annexation with the Planning Department.
The Community Development Department's Building division takes calls at (909) 625-9477. Inspection requests go to (909) 625-9448, and inspection results are available at (909) 625-9449. The walk-in counter is open 7 to 9 a.m. and 4 to 5:30 p.m., so plan visits around those windows.
What affects cost
- Whether old supply or drain piping can be repaired or should be replaced
- Work that reaches the City sewer and needs a Class A contractor
- Access through slab, plaster or finished ceilings
- Night or weekend work to keep a business open
- Permits and inspections
When you call
An independent local plumber who handles commercial work in Montclair will ask about the property, the symptoms and the best time for a shutdown. If the trouble may involve MVWD's main or meter, call the district as well, and if the job extends into the City sewer, confirm early who will hold the permit.
