In Calistoga, Hotel Guests Pay for the Town. Homeowners Pay for the Pipes.

A conserving single-family household in Calistoga uses about 4,490 gallons of water a month. In 2026 the city's water and wastewater charges for that home come to $313.73 a month, with $176.94 for water and $136.79 for wastewater. The next scheduled increase takes effect on January 1, 2027. A buyer closing this fall takes on that bill and its schedule along with the deed.

Very little else in Calistoga's civic budget lands on that buyer. Under the adopted FY 2026-27 budget, hotel guests fund 55% of the city's General Fund through lodging tax, and property tax is a distant second. Calistoga keeps these two systems apart. Homeowners pay for the town's water and sewer pipes. Visitors pay for most of the rest. Since the visitor side now depends on room prices more than on full rooms, buyers comparing Calistoga with other Napa Valley towns should understand both sides of the ledger.

The Bill That Comes With the Address

Calistoga adopted its current rate plan in 2023. Increases began March 1, 2024, and annual adjustments run each January 1 from 2025 through 2028. The city's Proposition 218 rate notice lists every step in advance. That makes Calistoga's utility costs easier to forecast than most of the costs a buyer carries.

Run the city's own 6-HCF example through the 2027 column and the monthly total goes from $313.73 to about $328.49. Water accounts for most of that change and wastewater for the rest. The figure is derived from the published schedule. Larger meters, irrigated grounds and higher use will produce very different numbers on an estate property.

The billing cadence is also changing. The city's January 2026 FAQ said all customers would move to monthly billing in fall 2026, after the first phase of a smart-meter rollout. The city's utility billing page still describes residential bills mailed every two months. For anyone prorating utilities at closing, the city's current billing cycle is worth confirming directly.

Why the Pipes Cost What They Cost

The rate schedule reflects two pieces of geography. The first is water supply. The city says about 70% of Calistoga's water comes from Barker Slough, more than 65 miles away, and about 30% comes from its own reservoir and treatment plant. A town that imports most of its water pays to move it.

The second is age. The city's rate FAQ estimates more than 3.5 miles of water pipe and 2.5 miles of sewer pipe at 75 to over 100 years old. It puts replacement at $7.5 million for the water pipe and $10.5 million for the sewer pipe, and lists $32 million in near-term utility projects and $41 million over ten years. The city's April 2026 sewer management plan reports that CCTV inspection of mains at least 75 years old is complete. It says replacement designs and financing are being developed and that repairs are expected to continue for several years. The work also shows up at street level. In 2026 the city began converting roughly half of its manually read meters to remote-read technology, and about 85 properties were scheduled for full meter replacements.

The rate FAQ ties this capital list to customer rates. A buyer's monthly utility cost is therefore linked to the condition of century-old pipe and a water source more than 65 miles away.

The Ledger Hotel Guests Fund

The General Fund pays for most of what a resident sees from the city outside water and sewer. Calistoga projects $22,432,326 in General Fund operating revenue for FY 2026-27, and its largest source is the 13% transient occupancy tax on short-term lodging. In order of size:

• Transient occupancy tax: $12.3 million, which the budget identifies as 55% of General Fund revenue
• Property tax: $3.26 million, about 14.5% of projected operating revenue
• Sales tax: $1.57 million, about 7%, and projected to decline as allocations from the county pool shrink
• Property tax in lieu of vehicle license fees: $1.23 million

Hotel guests contribute nearly four dollars for every dollar of property tax. Calistoga Mayor Don Williams has said the same thing in simpler terms. As the Napa Valley Register reported, he noted that about half of the city's budget comes from lodging taxes on hotel stays.

Record Revenue From Emptier Rooms

The structure of that 55% matters more than its size. Calistoga Currents reported in its August 27, 2026 edition that the city collected $12,958,844 in lodging tax in fiscal 2025-26. That was the most in its history and about $988,000 above the adopted estimate. Over the same year, occupancy averaged 53.5%, the lowest outside the pandemic in the 13 years the city has published the figure and down from 63.9% in fiscal 2021-22.

Both figures come from the same arithmetic. Lodging tax is a percentage of what guests pay, so receipts can rise while fewer rooms fill if the average rate keeps climbing. In fiscal 2025-26 the average nightly rate reached $566.55. Currents worked through the sensitivity. With occupancy unchanged, a 10% drop in room rates would cut collections by about $1.3 million. Making that up through volume alone would require about 11% more room-nights than the town sold last year.

The city's own forecast treats the year ahead as steady. The FY 2026-27 budget projects lodging tax at $12.3 million, up 3.1% over the prior year's budget. It expects room rates and occupancy to hold. That projection sits below the record $12.96 million actually collected, which leaves some cushion if rates soften.

New Rooms Arriving Into a Price-Led Model

Calistoga's lodging supply is about to grow, and that growth tests a revenue base built on price. Three properties show the range of what is happening.

1. Rosewood Calistoga, 515 Foothill Boulevard. Rosewood Hotel Group announced in August 2025 a January 2027 opening with 96 guest rooms, including 31 suites, plus 20 private villas and 13 estate homesites offered as Rosewood Residences Calistoga. More recent coverage gives a broader target date. Hotel Online described the resort on August 5, 2026 as set to debut in early 2027. The Napa Valley Register reported that the $500 million project had passed 50% construction completion. The city's project summary lists 110 guestrooms, so the published room counts differ.
2. The Veranda at Indian Springs, 1510 Lincoln Avenue. The city lists the project as under construction with Wright Contracting. It includes eight 8-plex guest buildings, nine bungalows, an adult pool and a café. Indian Springs' October 2025 announcement puts the addition at about 96 rooms. Neither the announcement nor the city's project page gives an opening date.
3. Calistoga Motor Lodge and Spa, 1880 Lincoln Avenue. At a September 4, 2026 trustee's sale, the lender, RREF IV-D DLI CML LLC, took ownership with a $20 million credit bid against $43,496,741 in unpaid debt and costs. A 50-room expansion announced in April would have taken the property to 102 rooms. The post-sale report gives no updated plan.

In a town where occupancy has been falling, two projects of roughly 96 rooms each are adding supply at the top of the market. If those rooms hold rate, the General Fund gains. If they compete on price, the Currents sensitivity math applies. The Motor Lodge announced its expansion in April, a month after its notice of default was filed, and the property went to its lender at a foreclosure sale in September.

For buyers at the top of the market, Rosewood also adds product of its own. The city describes the 20 villas as having individual pools and as proposed for separate sale and independent ownership. Rosewood says owners receive privileges through its Rosewood Reserve program. No pricing has been published. For the first time, a branded resort residence will compete with Calistoga's private estates.

Where the Housing Market Sits

Calistoga-specific monthly sales figures from this year were not available, so the closest reliable reading is county-level. In August 2026, according to the California Association of Realtors, Napa County's median sold price for existing single-family homes was $947,000. That was down 2.9% from August 2025, while sales rose 23.9% year over year. Unsold inventory fell to 6.6 months from 8.4, and median time on market rose to 91 days from 82.

More homes are selling, prices are slightly lower, and each sale takes longer. That pattern suggests buyers have room to negotiate and sellers are adjusting price to move. In Calistoga, the costs that come with ownership are easier to predict than the price. Utility charges are published through January 2028. Property tax makes up a modest share of what funds the town. Service levels depend largely on how well a growing lodging base holds its rates.

A Few Questions Buyers Ask

Will the 2027 utility rates show up before closing? The rates take effect January 1, 2027, under the schedule adopted in 2023. A home's current bill and the published 2027 column can be compared directly.

Is Calistoga Motor Lodge closing? The reporting covers a change in ownership through foreclosure. It does not report a closure, and no new operating or expansion plan has been published.

Are Rosewood Residences Calistoga for sale now? The developer, Calistoga Hills Resort LLC, an affiliate of Rosewood, is marketing the villas and homesites through a register-your-interest process. No prices or sales counts have been made public.

Does lodging tax affect a homeowner's tax bill? The 13% occupancy tax applies to short-term lodging stays. It is a separate revenue stream from property tax, and both feed the city's General Fund.
