Why Rigby Families Are Finishing Their Basements

Rigby is a small city with a big appeal. Located just 15 minutes north of Idaho Falls along Highway 20, Rigby offers the kind of small-town living that many families dream about — quiet neighborhoods, good schools, a strong community, and home prices that are meaningfully lower than Idaho Falls. That combination has made Rigby one of the fastest-growing small communities in Jefferson County.

Known as the Birthplace of Television — Philo Farnsworth developed the concept for electronic television while living in Rigby as a teenager — the city has a unique place in American history. Today, Rigby's appeal is more practical: families can buy homes with more land and lower price tags than comparable properties in Idaho Falls, while still being a short commute from Idaho Falls jobs, shopping, and entertainment.

New subdivisions in Rigby are attracting first-time homebuyers and families looking for more space. Most of these new homes are built with full unfinished basements, creating an immediate opportunity for homeowners to add 800 to 1,500 square feet of livable space. At $28 to $42 per square foot, finishing a basement in Rigby costs less per square foot than almost anywhere else you could add living space to your home.

The family-oriented nature of Rigby means most basement projects focus on practical living space. Extra bedrooms for growing families, open family rooms for movie nights and winter entertainment, and home offices for remote workers are the top three requests from Rigby homeowners. The goal is always the same: make the home work better for the family without the cost and disruption of moving to a larger house.

New Subdivisions & Growing Neighborhoods

Rigby's growth has been driven by new subdivision development that offers affordable, modern homes for families priced out of the Idaho Falls market. These new neighborhoods are being built with the same construction standards as Idaho Falls developments — full basements with plumbing rough-ins, properly sized electrical panels, and HVAC designed for lower-level expansion.

For homeowners in these newer subdivisions, finishing the basement is often the first major home improvement project. Because the infrastructure is already in place, costs are predictable and timelines are shorter. A family that moves into a new Rigby home in the fall can have their basement finished and ready for use by the time the deep winter sets in.

Older homes in established Rigby neighborhoods also offer excellent basement potential. Many were built with generous basements that were left unfinished or only partially finished. These homes may require a bit more prep work — moisture testing, electrical panel upgrades, and possibly egress window installation — but the resulting finished space adds significant value to homes that are already priced well below the regional average.

Whether your home is new or established, the before you start guide will walk you through every step of the pre-project planning process, from moisture testing to budgeting to contractor selection.

Popular Basement Styles in Rigby

Rigby homeowners gravitate toward practical, family-focused basement designs. Here are the most popular configurations in the Rigby market.

Family rooms with media areas top the list. An open-concept space with comfortable flooring, recessed lighting, and a dedicated wall for a large TV or projector gives families a dedicated gathering space for those long Idaho winters. Many Rigby families add a small snack bar area to reduce trips upstairs. See our family room guide for layout ideas.

Bedrooms for growing families are the second most common request. With larger family sizes common in the Rigby area, adding two or three bedrooms in the basement with a shared bathroom is a practical solution that avoids the need to buy a bigger house. Every bedroom needs an egress window to meet code.

Home offices have become increasingly popular as more Idaho Falls employers offer remote and hybrid work options. A dedicated basement office with proper lighting, plenty of electrical outlets, and sound insulation from the rest of the house is a significant upgrade from working at the kitchen table. Explore our home office guide for design tips.

Frequently Asked Questions — Rigby

Common questions from Rigby homeowners about basement finishing

How much does it cost to finish a basement in Rigby?

Basement finishing in Rigby averages $28 to $42 per square foot, putting it in the middle of the Eastern Idaho price range. A standard 1,000 sq ft basement typically costs between $28,000 and $42,000. Rigby benefits from its proximity to Idaho Falls — just 15 minutes away — which gives homeowners access to a competitive contractor market. Newer subdivisions with pre-done rough-ins will be on the lower end of this range, while older homes may cost slightly more due to additional prep work needed.

Do I need a permit to finish my basement in Rigby?

Yes. Jefferson County requires building permits for basement finishing projects involving framing, electrical, plumbing, or HVAC work. The Jefferson County Building Department processes permits for the Rigby area. You will need to submit a floor plan showing room layouts, egress window locations, and mechanical details. The permitting process in Jefferson County is generally efficient, and the building department staff are accessible and helpful for homeowners working through the process for the first time.

Can Idaho Falls contractors work in Rigby?

Yes, and most do. Rigby is only about 15 minutes north of Idaho Falls via Highway 20, making it an easy service area for Idaho Falls-based contractors. Many of the best basement finishing contractors in the region regularly serve Rigby and the surrounding Jefferson County area. This proximity gives you a larger pool of contractors to choose from and generally results in competitive pricing since contractors are not adding significant travel surcharges for the short distance.

What makes Rigby a good place to finish a basement?

Rigby offers a unique combination of small-town living with easy access to Idaho Falls amenities. Home prices are generally lower than Idaho Falls, which means a basement finish represents a proportionally larger increase in your home's value. New subdivisions are attracting young families who want more affordable housing without a long commute, and many of those new homes come with unfinished basements ready to be transformed. The lower cost of living and strong community make it an attractive place for families who want space to grow.

How long does basement finishing take in Rigby?

A typical basement finishing project in Rigby takes 4 to 7 weeks from the start of construction to completion. Simple single-room projects can be finished in 3 to 4 weeks, while multi-room builds with bathrooms and complex features may take 6 to 8 weeks. Add 1 to 2 weeks at the front end for permitting through Jefferson County. Scheduling is often easier in Rigby than in Idaho Falls since there is less competition for contractor availability, meaning you may be able to start your project sooner.
