Most of Rocklin runs near 1.1–1.25% of value before Mello-Roos, higher in the newer Whitney Ranch phases carrying CFD bond debt. As everywhere in California, expect a one-time supplemental bill about a year after closing for the gap between the prior assessed value and your purchase price.

Rocklin carries roughly a dozen Community Facilities Districts. Older, partly paid-down districts can run only ≈$300–$500/yr; newer tracts run into the thousands. Because the amount depends on the specific district and how much bond term is left, the parcel’s tax bill is the only definitive figure.

Rocklin’s oak-woodland and creek corridors carry mapped Moderate, High, and even Very High fire zones under the 2025 CAL FIRE maps, while flatter interior tracts are lower — so hazard genuinely varies block to block. Typical premiums run ≈$1,300–$2,400/yr for 95765 and 95677, with parcels near mapped zones running higher and a minority ending up on a FAIR Plan + wrap.

Rocklin is PG&E territory — roughly $290/mo at 750 kWh (June 2026), about double a Roseville Electric bill for the same power. A Rocklin home budgets very differently on power than a Roseville home a few miles away, so it is worth confirming the utility before you assume.
