Northridge Block by Block: Tampa Avenue to Bull Creek
Northridge sits just north of Reseda. The City's community plan describes the area as bounded by the Ronald Reagan Freeway (SR-118) and Devonshire Street on the north, Bull Creek on the east, Roscoe Boulevard on the south and Tampa Avenue on the west. Emergency dispatch runs around the clock, and naming the nearest cross street from that grid helps the dispatcher place you before they ask for the full address.
Three ZIP codes sit inside that grid. ZIP 91325 is the largest and is also written as Sherwood Forest on some mail. ZIP 91324 takes in the Tampa Avenue retail strip around Northridge Fashion Center at 9301 Tampa Avenue, so shop tenants and nearby apartment residents there can name the mall as a landmark. For a flooded kitchen or a failed water heater in any of them, emergency water removal comes first and drying follows.
Reseda Boulevard, Mixed-Use Buildings and Leaks That Travel
The Northridge plan treats the Reseda Boulevard business district as the community's focal point. It names the stretch between Halsted Street and Gresham Street as the primary community center and calls for mixed-use buildings of no more than three stories. Reseda Boulevard is also the line between the Northridge East and Northridge West neighborhood councils.
A building with shops below and apartments above stacks supply lines, drains and ceilings in the same walls. Water from one unit can surface two floors down, so ask the neighbor below to check their ceiling and tell the dispatcher every unit that is wet. The crew then maps moisture in each one instead of drying only the unit that called.
Water on a Northridge floor right now?
Call the 24/7 line. The dispatcher will ask for your nearest cross street and what is leaking, then walk you through the next step.
CSUN, ZIP 91330 and Leaks in Rented Homes
California State University, Northridge covers 356 acres at 18111 Nordhoff Street and has its own ZIP, 91330. Be clear about that code: it serves the campus itself and not a residential neighborhood, so most callers near campus live in 91324 or 91325. We cover all three.
Council District 12 says CSUN students are one reason for newer apartment and condominium buildings here. If you rent one, the California Attorney General's tenant guidance says to ask for repairs in writing and keep copies and photos. Photograph the leak and the wet ceiling before anyone starts drying, then send the dated pictures to your landlord. Our moisture logs add readings to that record.

When water is spreading in Northridge
A pipe does not wait for a weekday. Whether it is 3 a.m. or a holiday, the line is staffed, and a crew is sent as soon as the dispatcher has your address and the water category. Same-day response when available.
If Water Is Still Spreading
Northridge has long driveways and a lot of shared walls. These four moves protect both while the crew is on the way.
Close the right valve
In a house, shut the main valve near the street side or on an exterior wall. In an apartment or condo, close the fixture valve under the sink or behind the toilet and ask the manager about the building shutoff.
Cut power with care
If water reached outlets or the panel area, switch off breakers only when the panel is dry and you can reach it on dry ground. Otherwise stay back and call the utility or 911 before you call us.
Lift and photograph
Raise furniture onto foil or blocks and move rugs and electronics up. Photograph the water line and the source first. Renters should send those photos to the landlord the same day.
Warn the units below
Knock on the door under yours. Keep children and pets out of water that touched a toilet, a drain or a floor, then call the 24/7 line.
Washes, Channels and Checking Your Own Address
The plan names Bull Creek, a Los Angeles County flood control channel, along with Wilbur Wash and Aliso Canyon Wash as drainage corridors. It also lists floods and fires among the disasters that have affected the community. None of that puts your street in a flood zone. Search your address on the FEMA Flood Map Service Center and read the result yourself.
Homeowners and renters policies commonly exclude flood, so ask your insurer about separate coverage. LA County storm guidance adds that a 30-day wait before flood coverage starts is typical, so the time to ask is before the rain. After a storm, flood damage restoration covers Category 2 and 3 water.
The 1994 Earthquake and Repairs Behind Your Walls
The magnitude 6.7 earthquake of January 17, 1994 took this community's name, although Council District 12 places the epicenter near Reseda Boulevard and Saticoy Street, south of Northridge proper. For a buyer, the practical point is paperwork. Ask LADBS what permits are on file for an older address and ask the seller which plumbing was replaced, because a hidden repair is where a slow leak hides.
When a slow leak has been wetting drywall for weeks, water damage repair comes after drying, and mold may already be present. Mold needs moisture, so the leak must be fixed first. Testing and removal follow ANSI/IICRC S520, and any health question belongs to a physician. Our mold remediation team can scope the work.
Next Door: Winnetka and Tarzana
City Council District 12 lists Winnetka as a Northridge neighbor, and Corbin Avenue is Winnetka's eastern edge, so check the Winnetka water damage page if your address is on that side. Farther south, past Reseda, Tarzana has its own page with hillside notes.
Frequently Asked Questions
Is emergency water removal available in Northridge?
Yes. Same-day response when available, including nights, weekends and holidays. Extraction units, truck-mounted or hand-carried, go out first, with air movers and LGR dehumidifiers for drying afterward. Stop the source, then call the 24/7 line.
Do you cover every ZIP code in Northridge?
Yes: 91324, 91325 and 91330. ZIP 91324 includes the Tampa Avenue corridor and Northridge Fashion Center. ZIP 91325 is the largest and includes Sherwood Forest. ZIP 91330 is the single-entity code for the CSUN campus at 18111 Nordhoff Street.
The ceiling near CSUN is leaking from the unit above. What do I do?
Stop the water if you can reach a fixture valve, photograph the damage, and tell your landlord in writing. Then call us so the wet drywall is dried before mold can start. For unresolved unsafe conditions at a multifamily rental, the Los Angeles Housing Department takes code violation reports.
Is my Northridge address in a flood zone?
We cannot tell you that from here. Search the address on the FEMA Flood Map Service Center or use the LA County Flood Zone Determination site. Standard homeowners policies commonly exclude flood, so check your policy.
Who do I call for a broken water main or a meter leak?
LADWP lists a 24/7 line for water emergencies at 1-800-342-5397. Leaks on your side of the meter are yours to stop and dry, and that is where we come in.
Water still spreading? Call the 24/7 line at (818) 337-2642.
