Scottsdale's new water rates take effect November 1, 2026. The City Council approved a 4.5% increase in May, and part of that money is going toward new water sources as Colorado River supplies tighten. If you are moving to Scottsdale from another state, water is a good place to start, because it touches your monthly bill, your landscaping, and the questions you should ask before you buy. Here is what an out-of-state buyer should know about water, city taxes, the McDowell Sonoran Preserve, and the paperwork that comes with becoming an Arizona resident.
Scottsdale runs its own water utility with a mix of Colorado River, Salt and Verde River, reclaimed, and groundwater supplies, and the city says the current Tier 1 shortage has not reduced its supply. The city's combined sales tax rate is 8.0%, and its own property tax rate is $0.9124 per $100 of assessed value for 2025/26. In September 2026 the median sold price in Scottsdale was $950,000 with 4.57 months of inventory.

Water: what the shortage means at your tap
The Colorado River has been in a Tier 1 shortage in 2026, and the rules that have governed the river since 2007 expire at the end of this year. The Bureau of Reclamation released its Final Environmental Impact Statement for post-2026 operations in July 2026, and the new guidelines will set how Lake Powell and Lake Mead are run starting in 2027. The city says the exact impact on Scottsdale is not yet known.
What the city does say is that a shortage on the river does not mean a shortage at your tap. Scottsdale draws on Central Arizona Project water from the Colorado, Salt and Verde River water, reclaimed water, and groundwater, and it stores water underground for later use. The city is also studying advanced water purification, a groundwater purchase from the Harquahala Valley, and an expansion of Bartlett Dam on the Verde River, though KJZZ reported in June that no final decisions had been made.
For a buyer, the practical takeaway is cost and landscaping. Rates are rising, and the city says a significant portion of Scottsdale's water use happens outdoors. The city encourages desert landscaping and offers conservation programs and rebates. A yard full of grass and thirsty plants will cost more to keep up than a desert yard, and that gap is likely to grow.
Taxes and city services
Scottsdale's 1.7% sales tax funds police, fire, parks, libraries, and streets, and the city says almost 9% of it goes to buying land for the McDowell Sonoran Preserve and almost 18% to transportation. The rate was set by Proposition 490, which voters approved in November 2024 and which took effect July 1, 2025.
On property tax, keep the city's rate in perspective. The $0.9124 combined city rate is only one line on a Maricopa County tax bill. School districts, the county, community colleges, and special districts add their own rates, so the total bill on a Scottsdale home is a sum of many pieces. The Maricopa County Treasurer's site shows the full breakdown for any parcel, and it is worth pulling for every home you are serious about.
Becoming an Arizona resident
The Arizona MVD says you must register a vehicle you bring from another state as soon as you become a resident. You are considered a resident if, among other things, you stay in Arizona seven months or more in a calendar year, work here, or register to vote here. To register, bring your current title and registration from your previous state. Some vehicles in the Phoenix metro area need an emissions test first, and MVD suggests passing it before your visit.
For a driver license, MVD asks for proof of authorized presence in the U.S., your current out-of-state license or ID, and your Social Security number. If you want a Travel ID for domestic flights, you also need two documents showing your Arizona address, such as a utility bill or bank statement. MVD offices take walk-ins with no appointment needed.
Practical steps before you buy
- Confirm the jurisdiction. A Scottsdale mailing address does not always mean a home is inside Scottsdale city limits. Check the parcel on the Maricopa County Assessor's site, because city water, city services, and the city tax rate apply only inside the city.
- Ask who supplies the water. Inside the city it is usually Scottsdale Water. Outside it, the answer could be another provider, a private well, or something else. Get it in writing in the seller's disclosure.
- Look at the landscaping with your bill in mind. Ask the seller for recent water bills and note how much of the yard is turf.
- Pull the full tax bill. Use the Treasurer's parcel lookup, not just the city rate, to estimate your annual property tax.
- Map your routines. Scottsdale is long from north to south. Drive from the home to the places you will go every week, such as work, the airport, and your favorite trailhead, at the times you would actually drive.
- Check the school district for the address. If it matters to you, confirm which district serves a specific home directly with the district.
Avoid this mistake: assuming every home with a Scottsdale address gets the same water, services, and tax rate. Two homes a few miles apart can sit in different jurisdictions with different water providers. Confirm it on the parcel record before you write an offer, not after.
The honest caveats
The water picture is still moving. The post-2026 Colorado River rules are not final in their effect on Scottsdale, and the city's Colorado River update page says the impact on Scottsdale is not yet known. Future rate changes are possible. The city property tax rates above are for 2025/26, the most recent listed on the city's taxes page as of October 28, 2026. The $950,000 median covers single family homes, condos, and townhomes together across a large city, so it says little about any one neighborhood or price point. Prices in south Scottsdale and north Scottsdale can differ widely. Use these numbers as a starting point, and check current figures for the specific home and area you are considering.
Frequently asked questions
Is Scottsdale running out of water?
The City of Scottsdale says the current Tier 1 Colorado River shortage does not reduce its municipal water supply and that there are no mandatory water use restrictions. The city uses a mix of Colorado River, Salt and Verde River, reclaimed, and groundwater supplies and stores water underground. New river rules start in 2027, and the city says their exact impact is not yet known.
How much are Scottsdale water rates going up?
The City Council approved a 4.5% water rate increase in May 2026, and KJZZ reported that the new rates take effect November 1. Most of the increase covers infrastructure and operating costs, with a smaller portion for new supplies and conservation. Your own bill will depend on how much water you use, especially outdoors.
What is the sales tax rate in Scottsdale?
The combined rate for most purchases is 8.0%, made up of 5.6% state, 0.7% county, and 1.7% city. The city's use tax rate is 1.5%. The 1.7% city rate took effect July 1, 2025, after voters approved Proposition 490.
How soon do I need to register my car in Arizona after moving?
The Arizona MVD says you must register a vehicle from another state as soon as you become an Arizona resident. Bring your current title and registration from your previous state. Some vehicles in the Phoenix metro area need an emissions test before registration.
What is the median home price in Scottsdale right now?
The Scottsdale REALTORS September 2026 report shows a median sold price of $950,000 for single family homes, condos, and townhomes combined. Homes sold for 97% of list price with a median of 75 days in RPR, and there were 4.57 months of inventory. Prices vary widely by neighborhood and home type.
The bottom line
Moving to Scottsdale from out of state comes down to a few checks done early. Confirm the home is inside city limits, know who supplies its water, pull the full property tax bill, and plan your MVD visit. Rates are changing on November 1, and the Colorado River rules change in 2027, so build some room into your budget for water. The rest, from the trails in the preserve to the drive times across town, is easiest to judge in person.
