Idaho Falls & Rexburg, ID real estate: buy or sell with a local AXEN agent
These two towns sit in two different counties with two different assessors, and Idaho Falls owns something almost no city its size does: its own electric utility, with five hydropower plants. Rexburg's market is shaped by the university, and the Teton Dam failure is still part of the ground story north of town.

Buying a home in Idaho Falls & Rexburg: what to know
The rules that apply everywhere in Idaho are on the Idaho page. These are the Idaho Falls & Rexburg details that trip people up.
Get pre-approved →-
Idaho Falls owns its power company. Idaho Falls Power is a municipal electric utility serving the city, and it owns and operates five hydropower plants that deliver about a third of the city's electricity. Buying inside the city limits means buying into that utility.
-
City services cross the county line. The city's wastewater division maintains nearly 370 miles of sanitary lines and 38 lift stations, and treats wastewater and stormwater for the city and for areas of Bonneville County. So a county address may still be on city sewer.
-
Stormwater here runs through creeks, canals and washes. The city warns that what goes into a gutter reaches creeks, canals or washes and then the river. If a canal or ditch crosses the lot, find out who owns it, who maintains it and what rights run with it.
-
Two counties, two assessors, two appeal paths. Madison County values property at market value every year with physical inspections on a five-year cycle, and appeals go to the assessor then the county commissioners sitting as the board of equalization. Bonneville County is a separate office with its own process.
-
The Teton Dam failure is part of the ground here. The dam failed in June 1976, releasing about a million cubic feet per second and battering downstream communities. Ask about flood history and any repairs on older properties north and east of Rexburg.
Selling a home in Idaho Falls & Rexburg
Close out the Idaho Falls utility account properly.
Power, water, wastewater and sanitation all come from the city, and the power side is the city's own utility. Get a final reading on every service, not just water.
Know which county assessor holds your parcel.
Bonneville and Madison run separate offices, separate notices and separate boards of equalization. Get the right one before you answer a buyer's tax question.
Document any canal or ditch that touches the property.
Irrigation ditches and canals run through both towns. Put the maintenance responsibility and any easement in writing so it does not come up during the inspection period.
Idaho Falls & Rexburg real estate questions
Who provides electricity in Idaho Falls?
The city does. Idaho Falls Power is a municipal electric utility that owns and runs five hydropower plants, which supply about a third of the city's electricity. That is unusual for a city this size and it is one of the real differences between a city address and a county one.
Bonneville County or Madison County, and does it matter?
Yes. Idaho Falls is in Bonneville County and Rexburg is in Madison County. Different assessors, different notices, different boards of equalization and different building and zoning offices for unincorporated land. Confirm the county on the parcel before you rely on any tax or permit answer.
If I buy outside the Idaho Falls city limits, am I on a septic tank?
Not always. The city's wastewater division maintains almost 370 miles of sanitary lines and 38 lift stations and serves the city plus areas of Bonneville County. Some county addresses are on city sewer and some are not. Ask the city utilities office for your specific address.
What should I know about the Teton Dam flood?
The dam failed in June 1976, releasing roughly a million cubic feet per second and battering downstream communities. The dam is no longer a functioning structure. On older property north and east of Rexburg, ask about flood history and about any repairs done since.
Why does one page cover both towns?
Because buyers shop them together and the practical differences are county-level. Idaho Falls has the city utility and the larger job base. Rexburg has the university shaping its rental market. The assessor, the appeal path and the permitting office change between them.
