Ocean Park and Sunset Park have 1920s–1950s bungalows and Spanish homes with raised foundations. North of Montana has larger homes, and much of the city has older rent-controlled apartment buildings. Rent-controlled buildings often have decades-old supply lines, water heaters and drain stacks shared by many units, so a single failure can affect several households. Older bungalows in Ocean Park sit on raised foundations where marine air keeps crawlspaces damp.

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Santa Monica?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Santa Monica Building and Safety division.
Who pays for an apartment leak in Santa Monica?
Landlords usually handle the building, while tenants need renters insurance for their own belongings.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
