2026 Modular Home Costs: All In vs Factory Sticker
Factory stickers are not the price of a house. In 2026, a typical 1,600 sq ft modular posts $140,000 to $250,000 at the plant and $290,000 to $520,000 all in on owned land once foundation, tax, impact fees, freight, crane, and utilities are in. Use two columns on every quote.
Sticker versus all in
Dealers advertise the factory contract: structure, specified finishes, and sometimes a freight allowance. Appraisers and lenders care about as completed value: land improvements plus a code built house on a permanent foundation. Fannie Mae B2-3-02 only treats the dwelling as site built equivalent after it is real property. Your budget must fund that conversion. NAHB and RSMeans 2026 site built bands for a modest single family still cluster near $150 to $300 plus per sq ft hard cost depending on census division. Modular is not magically half of that once dirt is honest.
Worked example, 1,600 sq ft heated, inland county, owned lot, crawl space, mid finishes, 2026: factory $192,000 ($120 / sq ft), freight and crane $18,000, foundation $28,000, button up $42,000, utilities $16,000, permits and impact $9,000, sales tax $12,500, decks and driveway $22,000. All in about $339,500, or $212 / sq ft, before land. The sticker was 57 percent of the house cost and 0 percent of the land.
2026 cost per sq ft ranges
Heated area only. Garages and unfinished basements are extra. Regional labor, wind and snow engineering, and finish level swing the bands. HUD code manufactured is shown because buyers mix the labels.
| Path | Factory or hard cost sticker | All in on owned land (no lot price) | Notes |
|---|---|---|---|
| HUD manufactured, installed | $70 to $140 / sq ft | $110 to $190 / sq ft | HUD code. Different loans. Not IRC modular. |
| Modular, standard plan | $90 to $160 / sq ft | $180 to $280 / sq ft | Crawl or basement, inland, mid finishes |
| Modular, custom or coastal | $140 to $220 / sq ft | $260 to $380 / sq ft | HVHZ, high snow, or architect series |
| Stick built spec | n/a (all site) | $200 to $400 plus / sq ft | NAHB 2026 survey bands; custom exceeds |
Catalog anchors for order of magnitude: browse the collection, then add site. A compact Method Option style project prices like custom modular, not like a production HUD box.
Line items to put on the worksheet
Copy this into a spreadsheet. Get three bids on every site line. Factory is one number from one plant.
| Line | 2026 typical range | Watch |
|---|---|---|
| Factory modules (1,400 to 2,200 sq ft) | $130,000 to $350,000 | Finish package and structural options |
| Freight | $4,000 to $20,000 | Miles, escorts, oversize permits |
| Crane and set crew | $6,000 to $30,000 | Tight lots and 300 ton cranes |
| Survey, soils, perc | $1,200 to $8,000 | Failed perc redesigns |
| Clearing, grading, drainage | $4,000 to $35,000 | Rock, trees, wetlands buffers |
| Foundation | $12,000 to $90,000 | Slab chase vs crawl vs basement vs piles |
| Button up (seams, roof, siding joints) | $15,000 to $70,000 | Scope gaps vs plant |
| Well / septic or tap fees | $4,000 to $45,000 | Rural vs municipal |
| Electric service | $2,000 to $25,000 | Pole length and transformer |
| Driveway, walks, decks, garage | $8,000 to $80,000 | Often omitted from turnkey ads |
Foundation bands
Pier and beam or simple crawl: $8,000 to $22,000. Full crawl with access and vapor barrier: $14,000 to $35,000. Basement: $45,000 to $120,000 depending on walkout and waterproofing. Coastal piles: $25,000 to $80,000. Modular MEP in the floor needs a crawl or a designed slab trench. Do not assume a cheap slab "like a ranch" without plant engineering.
Sales tax and impact fees
Sales tax is a first class line item. Many states tax factory built housing when it is sold as tangible personal property. The dealer should show tax on the contract. Combined state plus local rates commonly sit between 4 and 8 percent. On a $250,000 taxable factory amount, that is $10,000 to $20,000. Some jurisdictions later treat the installed house as real property for annual tax, which is a different bill. Confirm with the county assessor after CO so you are not assessed as a HUD mobile in a park.
Impact and capacity fees are local. School and road impact in fast growth Florida and Texas metros often print $8,000 to $25,000. Colorado Front Range and California infill can exceed $20,000 to $40,000 when water meters are scarce. Rural Midwest townships may charge a few hundred for a zoning permit and nothing labeled "impact." Always ask the permit tech for the fee schedule in writing. Water and sewer tap fees sometimes sit in the utility company, not the building department.
| Fee type | 2026 planning band | When due |
|---|---|---|
| Building permit | $500 to $8,000 | At issuance, sometimes valued on construction cost |
| Impact / capacity | $0 to $40,000 | Permit or meter set |
| Sales tax on factory | 4 to 8 percent of taxable contract | Dealer invoice or closing |
| Highway / crane permits | $200 to $4,000 | Delivery week |
1,600 sq ft all in comparison (owned land)
| Type | 2026 all in band | Code and finance |
|---|---|---|
| Manufactured HUD | $160,000 to $280,000 | HUD; chattel or MH mortgage unless converted |
| Modular IRC | $290,000 to $520,000 | IRC; Fannie B2-3-02 real property |
| Stick built spec | $360,000 to $640,000 plus | IRC; longest on site schedule |
Time as a cost
Design and contract: 4 to 10 weeks. Permits: 4 to 16 weeks. Factory: 4 to 10 weeks, overlapping site. Set to CO: 3 to 8 weeks. Manufactured HUD can be faster on a prepared pad. Stick built specs still commonly run 8 to 14 months of on site weather. Carry cost: rate times average outstanding construction balance. Also count rent or bridge housing. A two month permit slip at $2,200 rent is $4,400 plus extra interest.
Financing product choice is not this page. For rates and FHA VA USDA, use 2026 financing. For how owners blow the site number, see owner regrets.
Must know before you sign a factory slot
Ask for a two column spreadsheet: plant and site. If freight is "included to 100 miles," price mile 101. If crane is "by owner," you do not have a turnkey number. Sales tax should appear as its own row with the rate and the taxable base. Impact fees should cite the ordinance or fee schedule date. A 2024 fee sheet is not a 2026 invoice.
Appraised as completed value has to cover the loan. If all in is $480,000 and comps support $420,000, you bring cash, cut scope, or wait. That gap is common on steep or remote lots where site cost is not in the comparable sales. FHFA conforming limits ($832,750 baseline in 2026) cap the GSE loan, not the wisdom of the bid.
FAQ
What is a realistic all in modular cost per sq ft in 2026?
Turnkey modular on owned land often lands at $180 to $320 per sq ft of finished heated area in 2026, depending on region, foundation, and finish. Factory stickers of $90 to $160 per sq ft are not all in. High cost coastal and mountain counties run higher.
What does the factory sticker exclude?
Land, survey, soil, permits, impact fees, sales tax on the building in many states, foundation, freight beyond a stated mile, crane, button up, utilities, driveways, decks, and landscaping. Always demand a two column quote: plant and site.
Do I pay sales tax on a modular home?
Often yes, on the factory contract, freight, or both. Rates follow the delivery state, commonly 4 to 8 percent. Some states tax the modules as tangible personal property until they become real property. Ask the dealer which line is taxable. A $220,000 factory contract at 6.5 percent is $14,300 of tax.
What are impact fees on a new modular?
Counties and cities charge one time fees for schools, roads, water, and sewer capacity. 2026 ranges run from under $2,000 in rural townships to $15,000 to $40,000 plus in growth counties in Florida, Colorado, and parts of California. They are due at permit, not at the factory.
Are modular homes cheaper than stick built in 2026?
Factory efficiency can cut 8 to 20 percent versus a comparable stick built spec on the same lot, mainly labor and waste. If site work is brutal, that gap closes. Manufactured HUD code still posts the lowest installed band but is a different product and loan.
How much contingency should I hold?
Hold 10 to 15 percent of the site package, not 10 percent of the factory sticker. Soil, rock, and utility length are the usual overruns. Factory change orders after production starts are 5 to 15 percent of the option price plus schedule slip.
How long until move in, and does time cost money?
Plan 4 to 9 months. Construction interest on a $350,000 C2P at 7.5 percent, average outstanding $180,000 for 6 months, is about $6,750. That is a real line item, not a rounding error.
