Mold Testing in Long Beach
Long Beach has a large stock of older apartment buildings, so a mold question here often involves both a tenant and a landlord trying to find out what is behind a stain or a smell. We test only, with no removal work to sell, so the report reads the same no matter who books it. Inspections are $495 for one unit or home up to 2,000 sq ft.
Why does mold show up in Long Beach homes and apartments?
The coastal humidity described on our South Bay & Long Beach page is part of it. The age and type of buildings explain the rest:
Older multi-unit buildings
Courtyard apartments and small walk-ups near the beach often have original plumbing and bathrooms without fans. One leak can affect several units.
Historic single-family districts
California Heights, Bluff Park and similar neighborhoods have homes from the 1920s and 1930s, often on raised foundations with crawlspaces.
Homes next to water
Naples and Belmont Shore sit beside the bay and canals, where the air stays damp and some lots have very little room for drainage.
Where does mold usually show up in Long Beach?
- Bathroom ceilings and walls in older apartment units
- Ceilings below an upstairs unit after a leak
- Crawlspaces under 1920s and 1930s homes
- Closets and window walls in homes close to the water
- Under kitchen sinks in units with original plumbing

Doesn't the city already inspect rental buildings?
Long Beach runs a Proactive Rental Housing Inspection Program for buildings with four or more units, which checks general housing conditions. An independent mold inspection is narrower and deeper: it focuses on one unit or concern, with moisture readings, photos and a written report. City of Long Beach: PRHIP
Can tenants book you directly?
Yes, as long as you can give us access to the unit. The report documents what we found and where, in plain language you can share with your landlord. We don't give legal advice.
