Colfax sits near the 1% Prop 13 base plus small local bonds, with no master-planned Mello-Roos overlay — a low property-tax town on paper. As everywhere in California, plan for the one-time supplemental bill about a year after closing that adjusts the assessment to your purchase price.

Colfax is a small, long-established foothill city rather than a CFD-financed master plan, so Mello-Roos is rarely a factor here — most parcels carry little or none. It’s still worth confirming on the actual tax bill, but this line seldom moves the Colfax number.

Fire risk and insurance are the real cost of a Colfax home. At around 2,400 feet in dense Sierra foothill forest, most of the city falls inside CAL FIRE fire-hazard zones, and carriers have been non-renewing foothill policies through 2024 and 2025. Many buyers end up on the California FAIR Plan plus a separate DIC (difference-in-conditions) wrap to satisfy their lender — effectively two policies. California’s 2026 Wildland-Urban Interface building code now also requires fire-rated (dual-pane tempered) windows and hardened materials for new construction, additions, and major replacements in these zones. Defensible space and home-hardening can earn FAIR Plan discounts, but treat insurance as a major, address-specific line: get a written quote before you commit, because in the highest-hazard pockets it can run several thousand dollars a year or more.

Colfax is PG&E territory — about $290 a month at 750 kWh (June 2026) — and at 2,400 feet the heating season is longer and colder than the valley, so real winter bills (and propane, where homes aren’t on piped gas) can run higher than a comparable Roseville or Sacramento home. Many rural-edge parcels also add well-pump power and septic upkeep that a city buyer may not budget for.
