Idaho Falls Home Values by Zip Code (2026)

If you're researching Idaho Falls home values by zip code, you're almost certainly doing one of three things: pricing your own home before a sale, scouting neighborhoods before a purchase, or underwriting an investment. The headline numbers matter, but what matters more is understanding why the zips differ — because the same house dropped into two different Idaho Falls zip codes can easily swing $80K–$120K in market value.

Here's the 2026 breakdown, zip by zip, with the context behind the numbers.

Idaho Falls Zip Code Values at a Glance

Ranges reflect typical transactional spread — not extremes. Luxury properties in the north end of 83402 and custom homes east of Hitt Road regularly exceed these ranges.

83401 — East & Central Idaho Falls

83401 is the broadest-reaching Idaho Falls zip and covers a lot of territory — from downtown and central neighborhoods east toward the Ammon city limits. Because it spans so much area, you'll find older mid-century homes priced in the $280Ks sitting just a few blocks from newer construction listed above $500K.

The eastern portion of 83401 (toward Hitt Road) is where appreciation has been strongest. It pulls from Bonneville Joint School District 93, which drives measurable demand and sustained pricing. The central portion has more age variance, so a street-by-street read matters far more than the zip average.

83402 — North & Central Idaho Falls

83402 has the widest price spread of any Idaho Falls zip. That's because it includes both modest starter inventory north and west of downtown and the historic north end — one of the most prestigious addresses in southeast Idaho.

The north end (north of Elva, along Placer and Tyndall) has stately early-20th-century homes on mature lots that routinely trade above $600K, with several trophy properties clearing $1M. A few blocks south, you can still find homes in the high $200Ks. Buyers targeting this zip need to be precise about which sub-area they're chasing.

83404 — West Idaho Falls

If affordability is the priority, 83404 is where the math works. West Idaho Falls has the largest concentration of starter homes, townhomes, and small multi-family inventory in the city, with most single-family homes trading in the $220K–$320K range.

This is the zip most investors target for rental yield — rents hold up well relative to purchase price, and tenant demand is steady thanks to proximity to employment, shopping corridors, and Idaho Falls School District 91. Appreciation has been solid, but not explosive; the value here is cash flow, not rapid upside.

83406 — East Idaho Falls (Ammon Corridor)

83406 is the fastest-appreciating Idaho Falls zip over the last three years. It covers the east-side corridor — much of it newer construction built in the last 10–15 years — along with portions that overlap into the city of Ammon.

Two forces drive this zip: inventory quality (newer homes, better finish levels, open floor plans) and school access (District 93). The combination puts sustained upward pressure on pricing even through broader market slowdowns. Expect median pricing in the low $400s, with many neighborhoods solidly in the $450K–$520K range.

Ammon (Bonneville County)

Ammon is technically its own city, but for real estate purposes it functions as Idaho Falls' most established eastern expansion. Newer subdivisions dominate — Sunnyside, Hawks Landing, Sand Creek, and others — and D93 school access keeps demand elevated year-round. Median values run $340K–$490K, with premium builders pushing inventory higher.

Shelley 83274

Shelley sits about 12 minutes south of Idaho Falls and offers meaningful value for buyers willing to trade a short commute for more house or more land. Median values run $290K–$420K. Shelley has its own school district (Shelley Joint School District 60), which is a draw for families who prefer a smaller-district experience.

Price Per Square Foot — Why It Matters More Than Zip Averages

Zip code medians tell you where buyers are paying more. Price per square foot tells you why. In 2026, Idaho Falls pricing ranges roughly from the mid-$130s/sqft in older west-side inventory to the $220s–$260s/sqft in newer east-side construction. We break this down in detail in our Idaho Falls price-per-square-foot guide.

How to Use Zip Code Data Without Getting It Wrong

• Buyers: Use zip data to narrow the shortlist, not to set your budget. A $425K house in 83406 and a $425K house in 83404 are rarely comparable.
• Sellers: Never price from zip averages. The highest-priced home in your zip isn't your ceiling, and the lowest isn't your floor. A sub-half-mile CMA is the only pricing tool worth trusting.
• Investors: Decide cash flow vs appreciation first, then let that pick the zip. 83404 optimizes for yield. 83406 and Ammon optimize for appreciation.
• Relocators: School boundary > zip code, every time. Two homes in the same zip can sit in completely different school zones.

The Bottom Line

Zip code data is useful shorthand, but it's shorthand. Idaho Falls has enough micro-market variation that the best pricing decisions always happen at the street level. Use the zip ranges above to orient yourself, then get a real comp analysis before you price, offer, or invest.
