What Rosemead homes are assessed at, and when
The 8,084 single-family homes on Rosemead’s 2025 roll are assessed from about $246,000 (lower quarter) to $631,000 (upper quarter), with a median of $411,000. Because Proposition 13 sets the assessment when a home changes hands, the year a home was bought matters more than what it would sell for today: at Rosemead’s median 1.16% rate, a home whose base year — the year its Proposition 13 assessment was last set, usually when it last changed hands — is before 1990 pays about $1,729 a year and one reassessed in 2020 – 2025 about $9,215.

LA County Assessor 2025 roll, single-family parcels by situs city; typical bill = median assessed value in the group × Rosemead’s median ad-valorem rate (1.1606%, shown rounded as 1.16% above), before Mello-Roos and direct assessments. Groups with fewer than 50 parcels are not shown. Base year is the land base year the Assessor carries; it resets on a change of ownership or new construction (reassessment rules). Market values are higher than these assessed values for most long-held homes.
Property tax in Rosemead, in context
On the 2025 Assessor roll, Rosemead’s taxable property was assessed at about $6.4 billion in total — up 5.2% from the prior year. Its residential roll of roughly 10,900 parcels is about 74% single-family homes, 6% condominiums and 21% small income properties (2–4 units). A typical single-family home is assessed at about $411,000 — an existing owner's Proposition 13 base-year value, not today's market price — for a typical annual tax near $4,770. By Los Angeles County standards those assessed values are relatively modest, which keeps typical bills lower than in the county's pricier cities. The typical single-family home dates to around 1950 and spans about 1,400 sq ft, and about 43% of them still carry a Proposition 13 base set before 2000 (a median base year near 2002) — a big reason long-time owners are assessed well below current prices.
Rosemead spans several Tax Rate Areas, so the ad-valorem rate ranges from about 1.16% to 1.22% depending on which voter-approved school and municipal bonds apply to a given parcel, all on top of the 1% Proposition 13 base. That figure is ad-valorem only: Mello-Roos (CFD) special taxes and fixed direct assessments — where a parcel sits in a district that levies them — are billed separately and vary parcel by parcel. Newer, master-planned developments are the most likely to carry Mello-Roos, so check your own bill for line items beyond the base rate. See the Los Angeles County Mello-Roos district list to check whether a community in Rosemead has a CFD special tax. For how the ad-valorem rate itself shifts across the county, see the Los Angeles property tax rate by ZIP code.
