Quick answer
Real all-in tiny home cost in 2026 runs $58,000 to $135,000 depending on model, region, and site prep needs. A $42,899 park model typically lands $58K-$70K installed. A $54,899 HUD single wide lands $68K-$85K installed. A $77,899 3-bed cottage lands $95K-$135K installed. Budget 15-30% above sticker price depending on geography.
Why sticker price is the wrong budget number
The single most common budget mistake first-time tiny-home buyers make is treating the base price as the cost of the home. It isn’t. The base price covers the unit itself — not delivery, not site prep, not utilities, not permits, not taxes, not insurance. Across 500+ deliveries I’ve tracked, real all-in cost runs 15-30% above the sticker, with the 30% end most common in California, New England, and tightly-zoned metros.
The 7 cost categories below add up to your real budget. Work through each one before you deposit on a unit; the combined number is what goes in your financing application.
The 7 cost categories that make up a real tiny-home budget
Category 1: Base unit price
The sticker. In 2026, reputable builders price as follows:
- $42,899-$49,900 — RVIA park models 399 sq ft (Hayden, Cedar Ridge class).
- $50,000-$65,000 — HUD-code units 500-700 sq ft (Key West class).
- $70,000-$85,000 — HUD or modular 800-1,000 sq ft (Homestead class).
- $75,000-$100,000 — HUD or modular 1,100-1,200 sq ft (Birch, Retreat class).
- $95,000-$180,000 — custom modular or double-wide configurations.
Category 2: Upgrades and options (add 4-12%)
Most buyers spec one or more upgrades above the base: premium flooring, granite counters, tile shower, stainless appliance upgrade, porch addition, extra windows. Plan $2,000-$12,000 in upgrades on a typical build.
Category 3: Delivery (add 4-9%)
Delivery from our Texas yards runs $400-$1,500 within Texas, $3,200-$4,800 to the southeast, $4,200-$5,400 to the mid-Atlantic, $5,800-$7,800 to the coastal West, and $6,500-$9,500 to the Pacific Northwest. Longer routes or difficult site access can add $500-$2,500.
Category 4: Site preparation (add 5-15%)
The biggest cost variable in the whole budget. Includes gravel or concrete pad, grading, driveway, tie-downs, skirting, well or sewer connection, electric service run, propane tank if needed. Ranges widely: $3,500 for a simple Texas pad to $25,000 for mountain placement requiring retaining walls or septic installation.
Category 5: Utility hookups (add 2-10%)
Separate from site prep, these are the actual connection fees: water meter connect ($0-$2,400), sewer tap ($0-$5,000), electric service activation ($150-$3,500), gas tank install ($400-$1,800), internet install ($0-$500). Rural placements with well + septic skip meter fees but spend on well drilling ($4K-$15K) and septic ($5K-$12K).
Category 6: Permits and inspections (add 0.5-5%)
Building permit, electrical permit, septic permit, foundation permit, ADU permit when applicable, certificate of occupancy. Rural unincorporated counties: $150-$1,400 total. Major metro ADU placements: $1,800-$6,500 total.
Category 7: Sales tax + insurance binder (add 0-9%)
Sales tax on the unit varies wildly: 0% in Oregon, Montana, New Hampshire, Delaware, Alaska; 6-7% most southern and mid-Atlantic states; 8-9% coastal California, NYC metro, Washington state. Insurance first-year premium: $400-$1,800.

Information gain: the 3 hidden costs buyers miss
Three cost items that don’t show up on most budget worksheets but bite most first-time buyers:
1. Survey and title work. $500-$2,400 depending on parcel complexity. Required for permit filing in most jurisdictions; often required by lender.
2. Temporary housing during site prep and delivery. 30-60 days between selling your current home and moving into the tiny home. Plan $2K-$8K in rental, storage, and moving costs.
3. First-year furnishing and setup. Even downsizing households typically spend $1,500-$5,000 on tiny-home-specific furniture (wall-mount desk, storage ottoman, space-saver furniture) that doesn’t transfer from traditional housing.
Add these three to your budget. Buyers who skip them end up financing at higher total cost through credit cards instead of the single tiny-home loan.
