Moving to Boise: A Complete Newcomer Guide to the Treasure Valley

TL;DR: Boise is the biggest city in a fast growing valley of connected towns. Plan on a 30 day window for your Idaho license and vehicle registration, set up power, gas, water, and trash before move-in, file for the homeowner’s exemption if you buy, and get to know the Greenbelt and foothills trails early. Housing costs vary a lot from town to town, so compare a few before you decide.

Welcome. If you are reading this, you are probably somewhere between “thinking about it” and “the truck is already booked.” This guide is the big picture. It covers the practical stuff you need in your first month, plus how the towns around Boise fit together. Wherever we use a number, we link the public source and say how current it is.

The Treasure Valley at a glance

Most people say “Boise” when they mean the whole metro. In practice, the Treasure Valley is a string of cities across two counties. Ada County holds Boise, Meridian, Eagle, Kuna, Star, and Garden City. Canyon County, to the west, holds Nampa and Caldwell.

Here is how big the main cities are, using the U.S. Census Bureau’s Vintage 2025 population estimates (as of July 1, 2025, released May 2026):

Place	2025 population estimate
Boise	238,429
Meridian	142,988
Nampa	120,384
Caldwell	76,629
Eagle	34,658
Ada County (total)	546,141
Canyon County (total)	275,123

Nampa and county figures come from the Census QuickFacts comparison table. Growth is the big story. Meridian alone went from 117,635 people in the 2020 Census to 142,988 in the 2025 estimate, about a 21% jump. The same Census tables list 5,221 building permits for Ada County and 3,929 for Canyon County in 2025.

What it costs to live here

Housing

Housing is the biggest line in most budgets, and it varies a lot by town. For September 2026, Boise Regional REALTORS reported a single family median sale price of $575,000 in Ada County and $443,523 in Canyon County. Redfin’s Boise housing market page showed a September 2026 median sale price of $540,742 for the city of Boise across all home types.

Census survey data gives a longer view, though it lags. The American Community Survey 2020 to 2024 estimates show these medians:

Place	Median value, owner occupied homes	Median gross rent
Boise	$484,800	$1,446
Meridian	$531,600	$1,805
Eagle	$772,900	$1,765
Nampa	$370,800	$1,420
Caldwell	$367,300	$1,264

Those ACS numbers average five years of surveys, so they run behind today’s market. They are still handy for comparing towns side by side. For the latest sales data, mortgage rates, and new construction trends, read our fall 2026 housing market snapshot.

Taxes

• Income tax: Idaho has a flat 5.3% individual income tax on income above a threshold, set in Idaho Code 63-3024.
• Sales tax: The state sales tax is 6%, per the Idaho State Tax Commission.
• Property tax: Rates depend on where you live. If you buy a home, read the homeowner’s exemption section below. It is easy to miss and can make a real difference.

Your first 30 days: license, car, and insurance

The Idaho Transportation Department’s New to Idaho page is the official checklist. The short version:

• Driver’s license or ID: Get an Idaho license or ID card within 30 days of becoming a resident. Active duty military members and their dependents with a valid out of state license are exempt.
• Star Card: Idaho’s Real ID compliant license is called the Star Card. If you want to use your license to board domestic flights, ask for it and bring the required documents.
• Title and registration: Title and register your vehicles within 30 days. ITD notes plates can take about six weeks to arrive.
• Insurance: Idaho’s minimum liability coverage is 25/50/15. Talk to your insurer about moving your policy before you register.
• Where to go: Driver’s license and vehicle offices are run by each county, not by the state, so look up your county’s DMV for appointments.

Setting up utilities

Who provides what depends on your address, so confirm with your landlord, builder, or title company. Here is a starting point for Boise addresses:

• Electric: Idaho Power handles start, stop, and move requests online or at 208-388-2323.
• Trash, recycling, and compost: In the city of Boise, start service through the City of Boise’s New Resident page, which links to Utility Billing. The same page links to parks, the library, and neighborhood associations.
• Water and gas: Providers vary by address. Ask your landlord or title company which companies serve the home.

Outside Boise, each city runs its own trash and utility billing, so check your city’s website.

Property tax and the homeowner’s exemption

If you buy a home and live in it as your primary residence, apply for the homeowner’s exemption with your county assessor. Per the Idaho State Tax Commission, it exempts 50% of the value of your home and up to one acre of land from property tax, up to a cap. The cap was $125,000 from 2021 through 2025.

In Ada County, the Assessor’s office says you must own and occupy the home by the last county business day in December, and apply by close of business that same day, for the current tax year. Once approved, you only reapply if you move or ownership changes. If you do not yet have an Idaho license or ID, the county requires you to provide that number within 90 days of applying, with an exception for active duty military on the first application. Bought new construction? The rules and timing are different, so read the newly constructed homes section on that page. Canyon County residents should check with the Canyon County Assessor.

Getting around

Most of the valley runs on cars, and commute times vary by town. The Census Bureau’s ACS 2020 to 2024 estimates put the mean travel time to work at 18.9 minutes in Boise, 22.4 in Meridian, 23.7 in Eagle, 24.4 in Nampa, and 24.6 in Caldwell. Those are averages across all workers, so your own drive depends on where you live and work.

• Buses: Valley Regional Transit runs bus service in Ada and Canyon counties, including routes between the two counties. Use its trip planner to see what serves your address.
• Ski bus: In winter, Bogus Basin runs a weekend public bus with pickups in Nampa, Meridian, Eagle, and Boise.

Before you sign a lease or make an offer, try the drive to work at rush hour. It tells you more than any map.

The outdoors

This is a big reason many people move here, and much of it is close to town.

• Boise River Greenbelt: A 29 mile pathway along the river from Lucky Peak through Boise and Garden City toward Eagle. It is open sunrise to sunset.
• Ridge to Rivers: More than 190 miles of trails in the Boise foothills, managed by a partnership that includes the City of Boise, Ada County, the Bureau of Land Management, the Boise National Forest, and Idaho Fish and Game.
• Bogus Basin: A nonprofit ski and summer recreation area about 16 miles north of Boise.
• Wildlife: The Deer Flat National Wildlife Refuge near Nampa, home to Lake Lowell, has a visitor center and trails open during daylight hours. South of Boise, The Peregrine Fund’s World Center for Birds of Prey has live bird programs.

Schools, kids, and family resources

Public school districts here are big, and boundaries follow addresses rather than city lines. West Ada, the largest district in Idaho, had 37,659 students in fall 2025, and the Boise School District had 21,386, per Idaho Education News.

To check which schools serve an address and how they report on state measures, use each district’s boundary tools and the state’s Idaho Report Card. Our Treasure Valley family resources guide walks through how to look things up, plus libraries, parks, child care search tools, and kindergarten rules. You can also browse the families hub.

Military households

Mountain Home Air Force Base is about 50 miles southeast of Boise. Some service members live in Mountain Home, and others commute from the Boise area. Our Mountain Home AFB guide covers the base, the drive, housing offices, schools, and vanpools. The military hub collects everything we publish for service members and veterans.

How to compare towns before you choose

There is no single “best” place in the valley. It depends on your budget, commute, and what you want nearby. A few ways to do your homework:

1. Price a few towns, not one. Use the medians above as a starting point, then look at recent sales for the specific size and age of home you want.
2. Drive it at different times. Visit on a weekday morning, a weeknight, and a Saturday.
3. Check the address, not the city. School boundaries, trash service, and even utility providers can change street by street.
4. Look at what is planned. New subdivisions, roads, and commercial projects are moving fast here. City planning pages and council agendas are public.
5. Ask locals. Neighborhood associations, library staff, and parks staff know a lot.
