Mold Testing in Santa Monica
Most Santa Monica households rent, so mold problems here often show up in apartments: a musty closet, a ceiling stain from the unit above, or a bathroom that never dries. Because we only test, our report is the same whether a tenant or a landlord books it. Inspections are $495 for up to 2,000 sq ft.
Why are Santa Monica apartments and homes prone to mold?
The city shares the Westside marine layer, but its housing mix matters more:
Small, older apartment buildings
Rent control covers a little over half of the housing in the city, and most of those units are in buildings with fewer than 15 units. Many are decades old, with original plumbing and bathrooms without fans.
Stacked units
A slow drain leak or failed tub seal upstairs often shows up first as a stain or smell in the unit below.
Blocks nearest the beach
Ocean Park and the areas west of Lincoln get more marine air than Sunset Park or the northeast of the city, so closets and window walls there stay damp longer.
Where does mold usually turn up in Santa Monica?
- Bathroom ceilings in older units with no exhaust fan
- Closets and bedroom walls on the ocean side of the building
- Ceilings below an upstairs bathroom or kitchen
- Window sills and frames in units with original windows

I rent. Can I book an inspection myself?
Yes. Tenants book with us directly, and you'll need to be able to give us access to the unit. The report describes conditions in plain language so you can share it with your landlord. We don't give legal advice; for tenant questions, the city's Rent Control Board is a good place to start.
Can a landlord use your report between tenants?
Yes. Many owners want a neutral record of a unit before it is re-let, especially after a leak. Since we have no remediation work to sell, the report only documents what is there.
