Utility Connection Costs in Colorado (2026): Tap Fees by City

Last reviewed: September 24, 2026By Utility Cost Guide research team

On the same 6,000 sq ft lot, a new single-family home pays about $16,525 in official water and sewer connection charges inside Denver and $15,216 inside Colorado Springs, based on the 2026 Denver schedules and the Colorado Springs Utilities tariff. Fort Collins starts lower, at $8,354 in plant investment fees, but it also requires raw water, either as water rights or as cash at $63,800 per acre-foot, which can make it the most expensive of the three. All three cities tie their water charges to lot size, which is the first thing to know about tap fees in Colorado.

The three cities side by side

To compare like with like, the table uses one set of assumptions: a detached home inside city limits on a 6,000 sq ft lot, the smallest standard residential meter, and the utility’s own tap and inspection charges where they are published. Each city’s page shows the full arithmetic and other lot sizes.

What Colorado’s fees have in common

Lot size drives the water charge

Each of the three utilities prices water capacity partly on lot area, but they do it in different ways:

Denver Water uses a straight formula: a base charge plus a rate per square foot, with the rate halved above 22,000 sq ft. Inside Denver from July 1, 2026 that is $3,380 + $1.01 per sq ft.
Colorado Springs Utilities uses eight lot-size tiers for both its Water Development Charge and its Water Resource Fee. Crossing from the 3,000–4,999 tier to the 5,000–6,999 tier adds $2,560.
Fort Collins charges $914 per first 3/4-inch tap plus $0.494 per sq ft, and stops counting at half an acre.

The practical effect: in Colorado, a bigger lot costs more to connect even when the house and meter are identical. On a 9,000 sq ft lot the Denver SDC rises to $12,470 and the Fort Collins water fee to $5,360.

Location outside the city costs more

Denver Water charges suburban customers $4,740 plus $1.42 per sq ft, so the 6,000 sq ft lot pays a $13,260 SDC outside Denver, $3,820 more than inside. CSU charges 50% more outside Colorado Springs city limits. Parts of Fort Collins are served by other water districts with their own fees. Always confirm which utility serves the parcel before using any of these numbers.

Water supply can be the biggest cost

Fort Collins makes new development supply raw water. At $63,800 per acre-foot, every tenth of an acre-foot assigned to a lot adds $6,380. Colorado Springs charges a separate Water Resource Fee, a fixed amount by lot tier that recovers the cost of water supply facilities for new development. Denver Water publishes a single SDC formula with no separate water-rights line.

What the official fees leave out

None of these charges pays for the private water and sewer lines on your lot, the trench, a street cut, or the building department’s plumbing permit. Our national estimates for that work, which you should replace with local bids (methodology): water service line $30–$150 per foot, sewer service line $50–$250 per foot, and a street cut or bore $1,000–$10,000 per crossing. The calculator combines the official fees with your own lengths:

Estimates are planning figures, not quotes. Confirm fees and trench rules with your utility.

Services and site work Water Sewer Electric Gas Road or driveway crossing needed Share one trench where allowed Utility confirms water and sewer may share a trench Pad-mounted transformer needed

Many codes require horizontal separation between water and sewer. This estimate assumes separate water and sewer trenches unless you select a shared run where your utility allows it.

Changes to watch in Colorado

Denver Water finished its two-step 2026 SDC phase-in on July 1, 2026; it was the first SDC change since 2013.
Denver’s sewer permit fee is set by calendar year; the 2026 sheet took effect January 1, 2026.
The newest CSU development charge sheet we found is dated 2025. Confirm current amounts with CSU.
Fort Collins’ plant investment fees were last amended in February 2024; re-check the water supply cash rate in the municipal code before paying.

Why do Colorado water tap fees depend on lot size?

Which Colorado city has the lowest connection fees?

Do Colorado suburbs pay more than the city?

Usually. Denver Water’s SDC outside Denver is $4,740 plus $1.42 per sq ft, and Colorado Springs Utilities charges 50% more outside city limits.

What is a water supply requirement in Fort Collins?

It is the raw water a new development must bring, either as water rights the utility accepts or as a cash payment of $63,800 per acre-foot under Sec. 26-129(c) of the municipal code.
