Four generations in Rigby, one builder

I’m the fourth generation of Swagers running businesses in Rigby and the first builder in the family. The line runs from Swager Ford, the dealership, through Swager & Swager Accounting, run by my grandfather and father, to SwagerBuilds. My own experience comes from 20 years in construction.

Four generations in one town means I already know the excavators, septic installers, lumber yards and county inspectors, with enough trades within 20 minutes of Rigby to keep windshield time out of the number.

I remain your single point of contact from design through move-in. An on-site project manager runs the day, coordinates the crews and posts the daily photo log. I stay involved in every phase, including the decisions that affect scope, cost and finish quality. You know who to call and who is responsible for the answer.

What does it cost to build a custom home in Rigby?

SwagerBuilds custom homes in Rigby start at $400 per square foot of interior living space for construction. That is our starting price, not a Rigby market average or an all-in budget. Your construction price becomes fixed after design lock, when the scope and selections are settled.

I use the starting number to establish your budget, then develop the plans, selections and site scope through the design agreement. You see what is included before signing the construction contract.

Design-build in Rigby: one team, one contract, one number

My design-build process in Rigby puts design coordination, selections and construction under one accountable team. We start with a design agreement, reach design lock, then sign a fixed-price construction contract. I do not use cost-plus contracts. Your number comes from a defined project, not an open-ended running total.

Design agreement

The design agreement covers plans, engineering coordination, selections and subcontractor bids by cost code. We start with a fixed design fee, quoted per project. We work through what is included before asking you to commit to construction.

Design lock and fixed price

Design lock means the plans, finishes and scope are settled and ready for pricing. That approved package becomes the basis of your fixed construction price. Later changes require written change orders approved before work moves.

Decisions and documentation

I group decisions into 7–8 scheduled meetings from kickoff to move-in. You see what needs choosing, when it is needed and what it affects.

The on-site project manager supplies a daily photo log. You receive a weekly recorded video walkthrough and a live job-site camera feed from day one. JobTread holds every drawing, selection, invoice and change order. See the full process.

Your home also includes a 1-year SwagerBuilds workmanship warranty, in addition to applicable protections under Idaho law.

Who I build for in Rigby and Jefferson County

I build new custom homes, barndominiums and ADUs for in-town Rigby owners, Jefferson County acreage owners and out-of-state landowners. The property and the way you use it shape the design. The working relationship stays the same: I remain your contact, and the project is documented from the start.

The in-town Rigby owner

You want roughly 2,000–3,800 SF on a City of Rigby lot with municipal sewer and water. You care about the layout, the daily use of the home and its resale appeal in Rigby. We work through the plans, selections and budget before construction, with each decision documented.

The Jefferson County acreage owner

Your site needs a well, septic, an engineered driveway, perc-test coordination and frost-depth engineering. I coordinate those requirements during design and scope the site work in the design agreement rather than leave it as an allowance. The construction price accounts for the property as well as the house.

The out-of-state landowner

You are building on family land or moving from a higher-cost mountain state. You follow the build through the daily log, live camera feed and JobTread, with a recorded video walkthrough every week. I remain your point of contact while the on-site project manager runs the day. See how remote-owner builds work.

Where we build around Rigby

I build in Rigby, along the Highway 48 corridor, around Menan and Menan Butte, toward Lewisville and Ririe, and in Annis and the Snake River corridor. Jefferson County acreage is part of the service area. I plan each build around its utilities, access, soils and permit requirements.

• In-town Rigby: I build on City of Rigby lots with municipal sewer and water.
• Highway 48 corridor: Larger acreage to the west combines mixed agricultural and residential zoning with well, septic and engineered drainage requirements tied to the irrigation ditch network.
• Menan and Menan Butte: Rural acreage means longer driveway approaches and roof engineering that accounts for prevailing-wind loading.
• Lewisville and Ririe: Lots are tighter than Menan acreage, with smaller-city permit paths, Jefferson County structural review for Lewisville and city application requirements for Ririe.
• Annis and the Snake River corridor: Some sites are floodplain-adjacent, making soils analysis and elevation certificates important to site planning.

How does the Jefferson County permit process work?

Jefferson County handles structural review, plan checks and building inspections for unincorporated county sites and for Rigby, Menan and Lewisville. City zoning requirements still matter inside city limits. The county uses the 2018 I-Codes. I confirm the property’s jurisdiction and approval path before construction begins.

Start with the parcel, not just the mailing address. For an unincorporated site, the county is the starting point for planning, zoning and building approvals. In Rigby, the city’s zoning review and the county’s building review are distinct steps.

The 2018 International Building Code and International Residential Code form the county’s stated building-code basis. I coordinate the plans and engineering information through the design agreement, including the requirements for the proposed residential use of a custom home, barndominium or ADU.

Plan review and permit issuance are project-specific in Jefferson County. I include that review stage in the schedule before site work and construction.

How long does a custom home take to build in Rigby?

Plan on 12–16 weeks for the design agreement phase, followed by roughly 10–18 months from permit to closeout. I plan exterior work around the March through November season. The schedule connects design, permit review, site work and construction so you can plan your move.

• Design agreement: 12–16 weeks.
• Plan review and permit issuance: project-specific in Jefferson County.
• Site work and foundation: 3–6 weeks.
• Framing through dry-in: 6–10 weeks.
• Mechanical, electrical, plumbing and inspections: 4–8 weeks.
• Finishes and punch: 10–16 weeks.
• Total: roughly 10–18 months from permit to closeout.

These work blocks sit within the full schedule, which also includes procurement and coordination. Design lock and the fixed-price construction contract set the scope for the build. The on-site project manager runs the daily work. I remain involved when decisions affect the scope, cost or sequence. Your daily log and weekly recorded walkthrough keep the progress visible.

What does it cost to build a custom home in Rigby, Idaho?

SwagerBuilds custom homes start at $400 per square foot of interior living space for construction. Garage area, covered porches and unfinished areas do not count toward that square footage. This is SwagerBuilds’ starting price, not a market average or an all-in quote. Your construction price is fixed after design lock.

Do you offer fixed-price contracts, or cost-plus?

I offer fixed-price construction contracts, not cost-plus. First, we complete the design agreement, including plans, engineering coordination, selections and subcontractor bids by cost code. After design lock, I present the fixed construction price for the agreed scope. Changes after that require written change orders approved before the affected work moves forward.

What is design-build, and why does SwagerBuilds work this way?

Design-build puts design coordination and construction with one accountable team. I use it so the plans, selections and budget are developed together instead of becoming separate problems for the owner to resolve. At SwagerBuilds, a design agreement comes first, followed by design lock and a fixed-price construction contract. I remain your single point of contact.

How long does a custom home take to build in Rigby?

Allow 12–16 weeks for the design agreement phase, followed by roughly 10–18 months from permit to closeout. Exterior work is planned for March through November. I coordinate the schedule around permit review, site work, framing, inspections and finishes. You follow progress through the daily log, weekly recorded walkthrough and JobTread.

Do you build on acreage outside Rigby (Menan, Lewisville, Ririe, Annis)?

Yes. I build new custom homes, barndominiums and ADUs on acreage around Rigby, including Menan, Lewisville, Ririe and Annis. I coordinate well, septic, driveway, perc-test and frost-depth requirements during design. Site work is scoped in the design agreement rather than left as an allowance, with the property’s requirements included in the construction pricing.

Is SwagerBuilds licensed and insured in Idaho?

SwagerBuilds holds Idaho Contractor Registration RCE-57499. Idaho registers general contractors rather than issuing a general contractor license. I am registered in Idaho only. Ask me for current insurance documentation before signing so you can verify the insured business, coverage and policy dates. Check registration and insurance as separate items.

What does the design agreement include?

The design agreement covers plans, engineering coordination, selections and subcontractor bids by cost code, under a fixed design fee quoted per project. It ends at design lock, when plans, finishes and scope are settled and I present the fixed construction price. Changes after that require written change orders approved before work moves.
