California Utility Connection Costs (2026): Tap Fees by City

Last reviewed: By Utility Cost Guide editor

In the three California cities we track, a new single-family home pays $10,466 (Fresno) to $23,732 (Sacramento, inside the combined sewer area) in official one-time water and sewer connection charges, under schedules effective in 2026. San Diego lands in between at $15,274, including the San Diego County Water Authority’s regional capacity charges. In our national tap-fee database, only Phoenix’s Northwest impact-fee area ($29,322) costs more than Sacramento’s combined-sewer-area total; Sacramento is higher than Denver ($17,380) and Charlotte, NC ($17,370), the next-highest large cities we track outside California. Private plumbing from the meter or tap to the house, trenching and permits come on top of every figure here — a 50-foot sewer lateral alone can add about $5,000 at the national rates each city page cites. Our database covers Fresno, Sacramento and San Diego so far. Other California utilities are not yet collected, and we say so rather than guess.

Official fees in California

The table below lists every verified California fee row in our database, with utility, meter size, fiscal year and a link to the source document. All three cities split one-time charges into a capacity charge and an installation charge, but they name and structure them differently. Fresno’s DPU charges a water capacity fee plus a wastewater facilities charge and a trunk sewer charge that depends on the lot’s sewer area. Sacramento’s DOU charges a water development fee plus one of two sewer development fees, depending on whether the lot is in the combined or separated sewer area. San Diego’s Public Utilities Department charges its own water and sewer capacity charges, and the San Diego County Water Authority adds a separate System Capacity Charge and Water Treatment Capacity Charge on top, billed by meter size.

City Utility Meter Situation Total

Split the totals apart, and installation is not what separates these cities. San Diego’s city-side taps, meter and lateral inspection cost just $390 ($254 wet tap + $111 meter + $25 inspection), because a licensed contractor builds the water service and sewer lateral at the owner’s expense; Fresno’s city-built meter and service installation costs $2,241; Sacramento’s city-built taps and meter cost $7,011 ($4,507 water easement tap + $723 meter + $1,781 sewer easement tap). Capacity fees vary far more. For water, Fresno’s capacity fee is $5,686.83, San Diego’s combined city-and-CWA water charges are $9,730 ($3,047 + $6,501 + $182), and Sacramento’s water development fee is $10,513.13 — almost double Fresno’s. For sewer, Fresno’s wastewater facilities and trunk sewer charges total $2,538 ($2,119 + $419), San Diego’s sewer capacity charge is $5,154, and Sacramento’s sewer development fee is $2,670.74 outside the combined sewer area or $5,936.84 inside it. Sacramento’s separated-area total is about $10,000 more than Fresno’s, and San Diego’s is about $4,808 more than Fresno’s.

What decides your number

Two of the three cities’ numbers are moving targets. San Diego’s CWA charges drop on January 1, 2027 to $5,617 for a meter under 1 inch, which would bring a new San Diego wet tap down to about $14,208. Sacramento’s post-phase-in schedule is not published yet. Confirm the current figure with the utility before you budget a permit near either date.

Frequently asked questions

How much do water and sewer connection fees cost in California?

It depends on the city. For a new single-family home under 2026 schedules, the City of Fresno charges about $10,466 with the minimum 1-inch service, the City of San Diego (with the County Water Authority) charges about $15,274 with a 1-inch by 3/4-inch meter and a new wet tap, and the City of Sacramento charges $20,466 outside the combined sewer area or $23,732 inside it.

Why is Sacramento so much more expensive than Fresno?

Capacity charges, not installation work. Sacramento’s water development fee alone is $10,513.13, nearly double Fresno’s $5,686.83 water capacity fee, and Sacramento’s city crews build the taps and set the meter for $7,011 versus Fresno’s $2,241. The gap between the two cities’ base totals is about $10,000 on a similarly sized home.

Does San Diego’s total include the County Water Authority’s charges?

Yes. The $15,274 figure combines about $8,591 in City of San Diego capacity, meter, tap and inspection fees with about $6,683 in San Diego County Water Authority System Capacity and Water Treatment Capacity charges, which the city collects at building permit issuance.

Are these the only costs of connecting a new home in California?

No. The private water line from the meter to the house, the sewer lateral, street-cut restoration and the plumbing permit are extra in all three cities — national estimates run $50 per foot for a water line and $100 per foot for a sewer lateral. City development impact fees for fire, parks and traffic, school district fees, and the electric utility’s own line-extension charges are separate too, and none of the three cities’ PG&E or SDG&E tariffs are in our totals.
