Cameron Park runs at roughly a 1.09% median effective rate with an unusually tight band — about 1.07% at the 10th percentile to 1.18% at the 90th (median bill divided by market value, April 2026). Compare that with El Dorado Hills next door, where the 90th percentile reaches 1.43%. The dollar gap is even starker: a median Cameron Park bill lands near $4,514 against roughly $8,083 in El Dorado Hills. Part of that is simply lower home values, but a real part of it is that Cameron Park largely built out before the Mello-Roos era.

Budget separately for the one-time supplemental bill that arrives roughly a year after closing — it reprices only the ad-valorem portion from the prior owner’s basis to your purchase price.

Most of Cameron Park predates the wave of Community Facilities Districts that shaped El Dorado Hills after 1993, so the majority of parcels here carry no Mello-Roos special tax at all. That is the single biggest reason the tax band stays so tight. It is not a guarantee: newer infill and annexed pockets can carry a district, and a parcel can also carry landscaping-and-lighting or other direct charges that are not Mello-Roos but still appear as flat dollars on the bill. Read the actual parcel bill rather than assuming a zero.

This is the question that catches buyers moving up from the valley. The Cameron Park and Shingle Springs corridor holds roughly 4,800 registered private water wells — the second-largest concentration in El Dorado County. Inside the core subdivisions you are generally on El Dorado Irrigation District water and sewer. Push east or onto the larger lots and you can be on a private well, a septic system, or both, which means pump replacement, water testing, septic pumping and eventual leach-field repair are your costs, not a utility’s.

A new domestic well permit in El Dorado County runs about $1,485 in 2026 before any drilling cost, and the county requires a minimum 100-foot setback from a septic system. Ask escrow for the well log and the most recent septic inspection.

El Dorado County is over 60% mapped Very High Fire Hazard Severity Zone and ranks among the state’s top ten counties for structures at high fire risk. Cameron Park is not high country, but the canyon edges and oak woodland running through and around the community mean the CAL FIRE designation genuinely varies parcel to parcel. That designation drives whether admitted carriers will quote you at all, or whether you end up on the California FAIR Plan with a separate difference-in-conditions wrap for everything fire does not cover.

Since 2025, SB 1060 requires California carriers to offer premium discounts for verified wildfire mitigation — worth asking about on any foothill parcel.

Electricity is PG&E with no municipal or community-choice alternative, so budget at PG&E rates. Cameron Park is unincorporated, so there is no city government — parks, recreation and fire service run through the Cameron Park Community Services District, which is funded through the property tax bill rather than a city budget. One genuinely unusual local feature: Cameron Airpark Estates is a residential airpark where homes have taxiway access to the runway, which carries its own association rules and costs that no listing site will surface.
