Everywhere else in El Dorado County the effective tax rate is boringly flat — roughly 1.04% to 1.09% from Placerville to Pollock Pines. El Dorado Hills is the exception, and it is not a small one. The median effective rate here is about 1.18%, the 75th percentile is 1.32%, and the 90th percentile reaches 1.43% (median bill divided by market value, April 2026). That is the widest spread of any community in the county, and the spread is not caused by the assessor. It is caused by which special-tax districts a parcel sits inside.

In dollars: the median El Dorado Hills tax bill is about $8,083, but the 90th-percentile bill is roughly $13,887. Price the parcel, not the town.

El Dorado Hills built out largely after the Mello-Roos era began, so the practical rule is that a neighborhood constructed after about 1993 very likely sits in at least one Community Facilities District — and overlapping districts are normal, so one parcel can carry more than one special tax. Named districts buyers run into include Serrano, Blackstone, Bass Lake Hills, Carson Creek Village, The Promontory, Kalithea, Watermark, Stonebriar, Hawk View, Creekside Greens, Heritage and Windsor Point. The El Dorado Hills Community Services District runs its own CFD 2018-01 (Bass Lake Hills) and CFD 2019-01 (District Master), and the county separately levies Carson Creek CFD 2014-1 and Carson Creek Village #11 CFD 2024-1.

Worth correcting a myth you will see on local real-estate sites: Mello-Roos is NOT a percentage of assessed value. It is a special tax set by each district’s rate-and-method formula — often keyed to lot size or home type — which is exactly how it sits outside the Prop 13 cap. Ask for the parcel’s annual special-tax schedule; the county CFD line is 800-676-7516.

Almost all of El Dorado Hills is on El Dorado Irrigation District water and sewer rather than a well and septic system, which is a genuine cost advantage over the rest of the county — about 2,900 private wells sit in the El Dorado Hills area versus roughly 4,800 in the Cameron Park and Shingle Springs corridor. What surprises new buyers is the second bill: many newer El Dorado Hills developments receive tertiary-treated recycled water through a separate purple-pipe system for landscape irrigation, so the irrigation line is metered and billed apart from the drinking-water line.

El Dorado Hills is the mildest fire story in a county that is over 60% mapped Very High Fire Hazard Severity Zone — but mildest is not the same as exempt. The western edges and the open-space corridors that make the community attractive are grass and oak woodland that carries fire, and the CAL FIRE hazard designation is parcel-level, not town-level. That designation is what decides whether admitted carriers will quote you at all or whether you land on the FAIR Plan with a difference-in-conditions wrap. AB 3074’s Zone 0 five-foot ember-resistant requirement is still being finalized in 2026, but carriers are already asking about it.

Get a written insurance quote for the specific address before you release your contingency — the same advice as everywhere in this county, just less dramatic here.

Electricity is PG&E, with no municipal utility and no community-choice alternative, so budget in the standard PG&E range rather than at a SMUD or Roseville Electric number. One structural point worth knowing: El Dorado Hills is not an incorporated city. It is an unincorporated community, so services come from the county plus the El Dorado Hills Community Services District and the local fire district — which is exactly why so much of the local funding runs through CFDs and district assessments instead of a city budget.
