Will a prefab home work on your lot? Three quick checks

Confirm these three things before ordering, with My Cozy Outdoors helping you think them through.

Does your zoning allow a single-family home?

Residential zoning permits houses inside cities and urban growth boundaries. Rural lots depend on county zoning. Farm or forest land needs dwelling approval first. Before ordering, ask planning about lot size, setbacks, height, design review and covenants.

Can the modules reach your lot?

Modules are about 15 ft wide. You need truck access, staging and a crane pad. Oregon Department of Transportation permits, daylight moves, pilot cars and mountain passes affect delivery. Irontown’s feasibility review checks your route and crane placement.

Do you have sewer and water, or will you need septic and a well?

Without sewer, you need septic permitting through the Department of Environmental Quality or its county agent. Your household well needs filing, and water districts provide will-serve letters. Irontown engineers your plans for snow, coastal wind and earthquakes.

Confirm your property requirements before ordering
This page is a starting point for planning a full-size home. MCO helps and advises but takes no responsibility for zoning, permits, impact fees, septic approval or code compliance. Before ordering, confirm your parcel, plan and use with city or county planning and building offices, and septic approval with the health department. MCO strongly recommends contacting those offices and can share the code sections it found and suggest questions.

Modular home prices in Oregon

Multi-State Designer Series starting prices run from $276,800 for Walker to $502,100 for Mill Creek. They include the home, delivery and standard crane set for the first 250 miles from Spanish Fork. All Oregon destinations are farther away. Extra transportation costs $12.75 per mile per truckload beyond those miles: about $2,500 to Ontario, $6,200 to Bend, $7,200 to Portland and $7,900 to Medford. A two-module home doubles those figures.

Approximate road miles from the factory

Starting price, delivered and set, plus estimated extra miles

Estimate only. Multi-State Designer Series starting price with standard delivery and crane set. Beyond 250 miles the rate is $12.75 per mile per truckload; a full-size home ships as two to four modules on separate trucks and is stitched together on your foundation, and your written quote confirms the count. Foundation, site work, stitch, utilities, permits, fees, engineering, pilot cars and sales tax are not included.

Choose your nearest town, plan and estimated truckloads in the calculator. Full-size homes ship as two to four modules on separate trucks. The calculator multiplies the extra mileage by the rate and estimated loads. Your written quote confirms the truckload count, any pilot cars and final pricing before construction.

What the starting price includes

  • Your finished modules in the Designer finish series
  • International Residential Code construction with mandatory Building Codes Division plan review, factory inspection and compliance insignia
  • Engineered, stamped plans for your building permit
  • Delivery covers 250 miles from Spanish Fork, with Oregon mileage per truckload shown in the calculator
  • The standard crane and set on your foundation
  • Irontown’s 10 year limited structural warranty

Costs not in the home price

These are your separate costs, including items charged by the general contractor, city and districts and quoted by the contractor and city, not MCO.

  • Land.
  • Site preparation and grading.
  • Foundation built to the structural engineer’s specifications.
  • Utility trenches, connections, septic and well work.
  • Stitching and finishing the seams between modules.
  • Steps, porches, decks and garages outside the plan, plus driveways and landscaping.
  • Permits, plan review, system development charges, excise taxes, utility connection fees and district charges.
  • Site and foundation engineering.
  • Applicable tax.
  • Transport touch-ups, including minor drywall cracks, caulk and door adjustments outside warranty coverage.

Your side of the budget includes land, foundation, site work, stitch, utilities, permits, system development charges, construction excise taxes, site engineering and applicable tax. Your general contractor prices the on-site work; the city and districts establish their charges. MCO does not quote those costs.

Your city or county may collect system development charges only for water, wastewater, drainage, transportation and parks under published methods at building permitting or utility connection (ORS 223.297 to 223.316). Permitting includes school and sometimes city construction excise taxes, while utilities set separate water and sewer connection fees. Most rural counties charge no county SDC, leaving school tax, permits, septic and wells. Ontario lists $1,288, Bend $26,900 to $34,800, and Portland waives roughly $39,000 for homes permitted through September 30, 2028.

Oregon does not have a general sales tax. Which taxes apply depends on your transaction. Irontown’s price excludes tax, and your written quote shows how tax is handled. After the set on your permanent foundation, the county assessor values your home with its land as real property each January 1. A home finished after January 1 is first valued the following January 1 (ORS 308.210).

Not a manufactured home, and why that matters

Your home is not built to the federal HUD code for manufactured homes. It is not a mobile home or a kit. Irontown builds it in sections at its Spanish Fork factory to the International Residential Code, which underlies Oregon’s statewide residential code. A crane sets those sections on your permanent foundation. On this page, prefab and modular mean the same thing.

Oregon calls your home a prefabricated structure. Irontown Modular (KEB Homes LLC) is a prefabricated structure manufacturer registered with the Building Codes Division. Oregon law requires the Division’s plan review, factory inspection and insignia of compliance on each module before occupancy. Your city or county accepts state code compliance without reinspecting factory work or opening walls. The plan approval and inspection path for your plan and site are confirmed with Irontown during the feasibility review.

Once set on its permanent foundation, your home is a permanent building and real property. The county assessor values it with your land. Most buyers use a construction loan that converts to a mortgage. Your lender decides whether conventional, Federal Housing Administration (FHA) or Department of Veterans Affairs (VA) programs apply.

Built for Oregon’s snow, coastal wind, earthquakes and wildfire

Irontown builds to the International Residential Code in Spanish Fork, then trucks the modules to your lot for a crane set on a permanent foundation. Irontown has delivered and built homes in Oregon. All Oregon destinations exceed the included delivery miles; the calculator shows extra transportation per truckload. During pre-construction, engineered plans address Cascade snow loads, coastal wind, seismic design and applicable wildfire rules.

Snow loads by elevation

Oregon’s address lookup gives your site’s ground snow load. Prescriptive design starts at 36 pounds per square foot (psf), with engineering required above 70 psf. Town centres read Bend 20, Sisters 29, La Pine 49, Portland 9, Medford 3, Lakeview 58 and Government Camp 327 psf. The floor governs most towns. Irontown’s engineered plans are stamped for your site’s loads, so a Government Camp lot gets a different roof and module design than a Medford lot.

Coastal wind and earthquake design

Basic wind speeds run about 94 to 103 miles per hour, reaching 120 in special coastal and Cascade regions. The seismic map places the coast and Willamette Valley in higher categories where seismic provisions apply. Code Table R301.2 and the Building Codes Division’s Oregon Design Criteria Hub give address-specific figures. Your building department checks your home’s fit with site snow, wind and seismic criteria. Irontown engineers your modules to those criteria during pre-construction.

Wildfire rules after the 2025 repeal

In 2025, lawmakers repealed the statewide wildfire hazard map and its mandatory home hardening and defensible space rules. Home hardening now depends on local adoption of R327 for mapped areas. Ashland, Deschutes County, Grants Pass and Sisters have adopted it. The State Fire Marshal‘s model defensible space code is voluntary for cities, counties and fire districts. County overlays may still require fuel breaks and roofing standards, as the rows explain. Where your county adopts R327 for your area, Irontown designs your modules accordingly during pre-construction.

One statewide code, energy and radon

Oregon has one residential code for the whole state, the Oregon Residential Specialty Code, based on the International Residential Code. The Building Codes Division adopts it. Your modules and inspected site work follow it. Cities and counties inspect, while the Division’s Pendleton office permits Morrow, Sherman, Umatilla and Wheeler Counties. Radon resistance is required in Baker, Clackamas, Hood River, Multnomah, Polk, Washington and Yamhill Counties. The code requires no house sprinklers, though fire district access or water supply rules may apply.

How long does an Oregon modular home take?

Irontown’s three phases total about five to seven months. Building permit review overlaps late pre-construction. Oregon law asks your city or county to decide complete simple residential plans within 10 business days, or 15 in Portland. Any rural, farm or forest land use approval runs first, separately. Your contractor’s site work adds time.

  1. Feasibility reviewIrontown · 1 to 2 weeksYour $2,000 review is credited to your contract. It covers a virtual site and route review, budget, schedule, building requirements, financing assistance and contractor support.
  2. Pre-construction and permitsIrontown and your city or county · 2 to 3 months plus permit reviewIrontown visits your site, guides finishes with its interior designer and supplies stamped snow, wind, seismic and wildfire plans. Your contractor applies for building permits after any land use approval.

Your city or countyIt handles zoning, setbacks, permits, insignia checks, site snow, wind and seismic criteria, foundation approval and occupancy. It inspects foundations, utilities, set and seams without reopening factory-built walls or reviewing factory work again.

Your Oregon general contractor

Your general contractor needs a state Construction Contractors Board (CCB) licence with a residential endorsement, only licensed subcontractors and written contracts with the board’s consumer notices above $2,000 (ORS 701.021). Irontown knows contractors, so contact MCO to see whether we can recommend one in your area. You can build your residence without a CCB licence by signing the state’s property owner statement at the permit counter and hiring only licensed subcontractors, electricians and plumbers (ORS 701.010). Your building department inspects the set and stitch.

Financing your modular home

Most buyers use a construction loan that converts to a mortgage after the home is set and finished. Your lender releases money in draws as work progresses. The lender decides whether Federal Housing Administration (FHA), Department of Veterans Affairs (VA) or conventional financing applies. My Cozy Outdoors (MCO) does not lend or promise approval. Irontown’s referral lenders understand modular construction and draws, but remain external references. Ask MCO for an introduction with your quote.

Oregon’s lien law puts you on notice early. For home contracts over $2,000, your contractor must provide the Construction Contractors Board’s Information Notice to Owner about construction liens (ORS 87.093). A contractor who skips it loses the right to lien your home. Subcontractors and suppliers protect their lien rights by sending you a notice of right to a lien. Any lien must be filed within 75 days of the last work.

City and county starting points

Before ordering, you must confirm property requirements with city or county planning and building offices, and septic with the county or DEQ.

Use these notes for Portland, Eugene, Bend, Medford, Central Oregon, the Oregon Coast and communities farther east. County rows cover unincorporated areas of that county; a city row applies inside city limits. Published fees and review schedules can change.

Zoning, delivery route and site detailsThe longer notes behind the three checks above

Inside city limits and urban growth boundaries, a single-family home is a permitted use on residentially zoned lots. Zoning and covenants govern minimum lot size, setbacks, height, coverage, design review and HOA rules. Outside, rural residential lots need to meet county dwelling tests. Farm and forest land requires a dwelling approval, such as a lot-of-record or template dwelling. The zone, dwelling right and covenants need to be established before ordering.

Delivery needs a workable truck route, staging space and crane pad. The carrier obtains ODOT over-dimension permits; travel hours and pilot cars depend on width and route. Mountain passes, chain rules and restrictions on movement in snow or ice affect scheduling. County and city permits cover local roads. Irontown reviews the route and the last miles to your lot during feasibility.

Rural lots may need septic through DEQ or its county agent, an exempt household well or a water district’s will-serve letter. Ground snow loads change with elevation, and coastal sites need seismic and wind design. Applicable wildfire rules also shape the plans. Irontown addresses these site requirements during pre-construction.

How Oregon regulates a modular home

These state rules shape your project, and the section references help your building department find the details.

  • Oregon has one statewide residential code based on the International Residential Code. A factory-built house built to it is a prefabricated structure, not a manufactured dwelling. Your city, county or the Building Codes Division administers the code.ORS 455.010; ORS 455.030
  • Irontown Modular, operating as KEB Homes LLC, is a registered prefabricated structure manufacturer with the Building Codes Division. Oregon law requires Division plan review, factory inspection and insignia of compliance for every factory-built home sold statewide. Your project’s plan approval and inspection path are confirmed with Irontown during feasibility review.ORS 455.705; OAR 918-674
  • Your city or county checks the insignia, zoning, setbacks and site criteria and approves your foundation plan. It inspects utilities, the set and seams between modules. It may not open factory-built walls or re-review your home for code compliance.OAR 918-674-0540; ORS 455.148
  • Residential zoning permits houses inside cities and urban growth boundaries. Rural residential lots face county dwelling tests, while farm and forest land needs dwelling approval first. Land use decisions run separately, taking 120 days inside cities or urban growth boundaries and 150 days elsewhere.ORS 197A.395; ORS 197A.400; ORS 215.284; ORS 215.705; ORS 215.750; ORS 215.427; ORS 227.178
  • Complete simple residential plans need decisions or referrals within 10 business days. Places with 300,000 or more people, including Portland, get 15 business days. Complex plans and other agency approvals are exceptions. Permission is not automatic, and your city or county’s review adds time.ORS 455.467; ORS 455.465
  • Your city or county may collect system development charges at permitting or utility connection. Published totals range from Ontario’s $1,288 to about $39,000 in Portland before its waiver. School and local construction excise taxes and utility connection fees may apply separately.ORS 223.297 to 223.316; ORS 320.170; ORS 320.192
  • State code does not require house sprinklers. Lawmakers repealed statewide map-based wildfire mandates in 2025, but locally adopted wildfire rules and overlays can still apply. Your fire district may also require access or water supply measures.ORS 455.433; ORS 476.392; Senate Bill 83
  • Your written quote explains how tax is handled. After the set, your county assesses the home with its land as real property. Septic permits go through the Department of Environmental Quality or its county agent. Household wells follow Water Resources Department rules.ORS 308.210; ORS 454.655; OAR 340-071; ORS 537.545
  • Your contractor needs a residential Construction Contractors Board licence, with written contracts and consumer notices above $2,000. You may qualify to build your own home under the owner exemption and statement rules. Construction lien notices apply, and liens require filing within 75 days.ORS 701.021; ORS 701.010; ORS 701.325; ORS 87.093

Visit the Spanish Fork factory

Walk through finished modules on Irontown’s factory line and see the finish series in person. Spanish Fork is about an hour south of Salt Lake City International Airport, with direct flights from Portland International Airport. Ask MCO about arranging your visit.

Common Questions

Irontown’s Multi-State Designer Series starting prices run from $276,800 for Walker to $502,100 for Mill Creek. Delivery and crane set include 250 miles; all Oregon destinations exceed them. Beyond that, transportation is $12.75 per mile per truckload: about $6,200 to Bend, $7,200 to Portland. Land, site work, foundation, stitch, utilities, permits, engineering, fees and taxes are extra.

No. This modular home is a prefabricated structure built to Oregon’s residential building code, based on the International Residential Code. A manufactured home follows the federal HUD code. Here, prefab home and modular home mean the same factory-built product set on a permanent foundation.

Oregon law requires Division plan review, inspection and its insignia of compliance. Irontown Modular (KEB Homes LLC) is registered with the Division; your plan approval and inspection path are confirmed during feasibility. Local officials still review the foundation and site criteria and inspect utilities, the set and connections between modules.

Irontown allows 1 to 2 weeks for feasibility, 2 to 3 months for pre-construction and 12 to 16 weeks for construction and delivery. Local permit review is additional. Site readiness and permit or construction delays can affect delivery.

Published charges vary widely: Ontario lists $1,288 for transportation, Bend totals about $26,900 to $34,800, and Portland totals about $39,000 before its conditional waiver. School and local construction excise taxes are separate, as are utility connection fees. The city, county and utility schedules determine which charges apply.

Rural residential lots must meet county tests; farm and forest land needs a dwelling approval such as lot-of-record or template. Snow loads vary by elevation. After the 2025 repeal of statewide map-based mandates, locally adopted wildfire rules and overlays can still apply. Irontown engineers the plans for applicable site requirements during pre-construction.

Most buyers use construction financing with staged draws that converts to a mortgage after completion. Irontown has referral lenders familiar with modular construction. Ask MCO for an introduction with your quote, and ask your lender about FHA, VA or conventional eligibility. Approval is the lender’s decision.

Yes. A general contractor handles foundations, utilities, set-day coordination, stitching and finishing, with an Oregon CCB residential licence. Qualifying owner-builders have a separate route with licensing and statement conditions. Irontown’s feasibility review includes contractor support; MCO can discuss whether a recommendation is available in your area.

The largest plans are Thatcher at 1,860 sq ft from $423,200 and Mill Creek at 2,198 sq ft from $502,100. Multi-State Designer Series prices include delivery and set within 250 miles of Spanish Fork. Every Oregon lot adds $12.75 per mile per truckload beyond that. Each ships as about four loads, adding roughly $6,200 per load to Bend or $7,200 to Portland. Your quote prices Modern, Balance and Rustic finishes and changes. Your site budget is separate.

Not with a full-size plan. Walker starts at $276,800 for 1,165 sq ft. Smaller modular ADU homes include one bedroom Mysa 500, from $142,600 for 497 sq ft. Both include delivery and set within 250 miles of Spanish Fork. Smaller park model homes include Cabana 200 studios, from $65,800 for 200 sq ft. Whether a smaller home may sit on your lot is your city or county’s zoning call. Oregon mileage, land and site work cost extra. Ask My Cozy Outdoors for a written quote.

You can choose the Aspen with three bedrooms and 1,255 sq ft from $296,700, the Donner 1300 with 1,315 sq ft from $330,900, or the two story Bunkhouse with 1,588 sq ft from $379,300. Prices include delivery and set for the first 250 miles from Spanish Fork, then $12.75 per mile per truckload. Loads cost about $5,900 to Klamath Falls, $6,200 to Bend and $7,900 to Medford. Your cabin arrives as finished modules built to the International Residential Code and engineered for your snow load, not kits.

Multi-State Designer Series prices start at $276,800 for Walker and reach $502,100 for Mill Creek. Portland is about 816 road miles from Spanish Fork. Extra delivery is about $7,200 per truckload, or $14,400 for two modules. Portland waives its roughly $39,000 system development charges for homes permitted through September 30, 2028. City housing, Metro and school construction excise taxes still apply. Its permit page lists modular homes under the manufactured home application. Ask the permit centre which application applies before choosing a plan. Your site budget is separate.

Inside cities or urban growth boundaries, residential zoning permits houses. No city or county may exclude prefab homes from every residential zone. Rural residential permission depends on county zoning, as the rows explain. Farm land needs farm, non-farm or lot-of-record dwelling approval. Forest land needs template, large-tract or lot-of-record approval. County decisions run separately before building permits. Zoning, lot size, setbacks, height and covenants still apply. Confirm your zone and dwelling right with county planning before ordering.

Your starting price covers Designer modules, stamped plans, included delivery miles, standard crane set and the structural warranty. Separately, budget for land, foundation, site work, stitch, utilities, permits, engineering and any tax shown in your quote. Add system development charges, construction excise taxes, water and sewer connection fees, and any fire, school or irrigation district fees. Delivery beyond included miles costs extra per truckload, with pilot cars when required. Your contractor, city and districts price their work and charges. My Cozy Outdoors does not quote them.

On its permanent foundation, your home is a permanent building and real property, not a titled vehicle or manufactured home. Your county assessor values it with the land each January 1. Homes finished afterward are first valued the following January 1. Oregon has no general homestead exemption. Homeowners 62 or older or with a disability may defer property taxes. Buyers use construction loans converting to mortgages. Ask your lender about conventional, Federal Housing Administration or Department of Veterans Affairs programs.

Modules about 15 ft wide need truck access, staging and a crane pad. Every Oregon lot exceeds 250 included miles, adding mileage per truckload and any pilot cars. Daylight-only moves, mountain passes, holiday blackouts and winter closures affect delivery. Your contractor separately prices foundations, utilities, stitch and finish. Customization stays within plans and finish series. Budget for normal transport touch-ups, including drywall cracks and door adjustments, outside warranty coverage. Irontown’s feasibility review flags these before you commit.

Rules were read in September 2026. This summary is not legal advice or approval. Rules change, and local offices decide how they apply. You are responsible for confirming zoning, permits, impact fees, septic approval and code compliance for your parcel, plan and use before ordering. MCO helps and advises but takes no responsibility for those matters.
