A tiny house costs $30,000 to $70,000 on average on HomeGuide’s latest figures, at $150 to $250 per square foot prefab and $250 to $450 custom (January 2026)1. HomeAdvisor publishes a $30,000 to $60,000 normal range with a $45,000 average (June 2026)3, and Angi the same $30,000 to $60,000 most-projects band inside a $2,000 to $180,000 overall span (August 2026)2. Angi and HomeAdvisor are corporate siblings, and matching figures alone don’t establish independent corroboration — their pages match on many rows below, with HomeGuide providing the independent comparison. All figures are the latest published data from each source.
Prefab vs. custom
HomeGuide splits prefab into three tiers: an unassembled kit at $4,000 to $30,000 (blueprints and materials, no interior finishing), a finished exterior shell at $15,000 to $40,000, and a fully finished prefab house at $25,000 to $80,000 — with a custom build at $50,000 to $140,0001. All three publishers put the shell at $15,000 to $40,000123. Beyond it the framings diverge: Angi’s prefab span runs $4,000 to $180,000+ including high-end custom models, and HomeAdvisor prices kits at $4,000 to $10,000 against custom builds over $150,000 — different kit and custom scopes than HomeGuide’s, presented as published123.
Cost by size and bedrooms
HomeGuide’s size table, fully assembled prefab against custom-built1:
| Size | Prefab (HomeGuide) | Custom (HomeGuide) |
|---|---|---|
| Small (90–250 sq ft) | $15,000–$50,000 | $30,000–$70,000 |
| Medium (250–300 sq ft) | $30,000–$80,000 | $50,000–$125,000 |
| Large (300–400 sq ft) | $45,000–$100,000 | $80,000–$150,000 |
| Extra-large (400–600 sq ft) | $70,000–$125,000 | $100,000–$200,000+ |
Its bedroom table tracks the same ranges: studio $15,000 to $50,000 prefab ($30,000 to $70,000 custom), one bedroom $30,000 to $80,000 ($50,000 to $125,000), two bedrooms $45,000 to $100,000 ($80,000 to $150,000), three bedrooms $70,000 to $125,000 ($100,000 to $200,000+)1.
Cost by base type
| Base type | HomeGuide | Angi | HomeAdvisor |
|---|---|---|---|
| Foundation | $33,000–$78,000+ (excl. land) | $51,000–$53,000 avg, to $180,000+ | $51,000–$53,000, to $180,000+ |
| Wheels / trailer | $30,000–$70,000+ (incl. trailer) | $60,000–$80,000 | $60,000–$80,000 |
| Shipping container | $20,000–$50,000 (one container) | $20,000–$45,000 | $20,000–$45,000 |
| Bus conversion | $30,000–$50,000 | — | $30,000–$130,000 |
The siblings match row for row while HomeGuide diverges on foundation and wheels builds — its wheels figure includes the trailer against the siblings’ higher $60,000 to $80,000, and its foundation figure excludes land — presented as published123. Multi-container homes run $100,000 to $250,000+ on HomeGuide, with a used 20-foot container at $1,500 to $5,000 and a 40-foot at $6,000 to $8,000; HomeAdvisor prices the container itself at $1,500 to $5,00013. Angi adds a shed-to-tiny-house conversion at $2,000 to $25,0002.
Foundation and site costs
HomeGuide prices a concrete slab foundation at $6 to $14 per square foot, or $12,000 to $28,000 total, with pier footings and crawlspace foundations at the higher end1. Angi and HomeAdvisor both publish a $5,000 to $8,000 foundation total; per square foot, Angi lists $4 to $7 while HomeAdvisor’s own page diverges internally — $4 to $7 in its factor table against $5 to $18 in its foundation section, an intra-source difference presented as published123. On land, HomeGuide publishes $5,000 to $18,000 per acre against HomeAdvisor’s $3,000 to $150,000 total — different units, presented as published13. Surveys run $200 to $1,200 on HomeGuide, $500 to $750 on Angi, $400 to $800 on HomeAdvisor — three slightly different ranges123.

On shares, Angi and HomeAdvisor both put materials at 30% to 50% of the project ($14,100 to $54,800) — a sibling match — while labor shares split: HomeGuide 40% to 60% against HomeAdvisor’s 30% to 60%, presented as published123. HomeAdvisor adds appliances and furnishings at $400 to $4,000, maintenance at $550 to $1,000 per year, and insurance at $100 per month against HomeGuide’s $35 to $125 per month — divergent framings, presented as published13.
Systems and utilities
HomeGuide’s figures: plumbing $1,000 to $7,000 including the water heater, wiring $750 to $3,500 with an electrician at $50 to $130 per hour, a water main $32 to $53 per linear foot plus up to $2,000 to $3,000+ for the meter, a sewer line $40 to $180 per linear foot, septic $3,500 to $8,500, and grid connection $250 to $1,500+ ($2,000 to $5,000+ rural)1. HomeAdvisor’s ranges run wider: grid connection $250 to $5,000 and sewer connection $500 to $20,000 — presented as published13. On heating and cooling, HomeGuide lists a window AC at $150 to $800, a ductless mini-split at $2,500 to $6,000 installed, a wood stove at $3,000 to $8,000, and baseboard or propane heaters at $200 to $1,100 and $200 to $8001.
Trailers and lot rental
A tiny-house trailer costs $4,500 to $11,000 on HomeGuide — bumper pull, gooseneck, and 5th-wheel styles — against $4,500 to $9,000 on HomeAdvisor, a shared low end with a divergent top13. For a house on wheels, HomeGuide prices RV or campground lot rental at $250 to $1,500 per month depending on included utilities1.
Permits and zoning
Zoning and permit rules vary widely by city and state, so confirm with your local building authority before committing to a build — where a tiny house may be placed, and whether it counts as an ADU or an RV, is a local decision. The published permit estimates diverge: HomeGuide $1,000 to $2,000 (with its own breakdown table listing $1,000 to $1,400 — an intra-source difference, presented as published), Angi $400 to $2,300, HomeAdvisor $500 to $3,100123.
Brands and builders
HomeAdvisor’s brand example: a Tumbleweed tiny house starts at $90,000 and reaches $250,000 for custom-built models — its figure, attributed3.
Timeline and lifespan
Building a tiny house takes 2 to 4 months for a custom or fully finished prefab build on HomeGuide1; Angi puts a professional build at 120 hours on average — a different unit, presented as published2. On lifespan, HomeGuide’s own comparison with a small house (600 to 1,000 square feet): a tiny house at $30,000 to $70,000 against $60,000 to $155,000, 2 to 4 months against 7 to 8, and a 20-to-50+-year lifespan against 70 to 100+ — its figures, attributed1.

The bottom line
Budget $30,000 to $70,000 on HomeGuide’s average, or the narrower $30,000 to $60,000 band Angi and HomeAdvisor share, with a $45,000 average on HomeAdvisor. The build-type choice moves the total most: an unassembled kit starts at $4,000 on all three pages, a finished shell runs $15,000 to $40,000 across the board, and custom builds pass $140,000 on HomeGuide and $150,000 on HomeAdvisor. Land, the foundation or trailer, utility hookups, and permits each carry their own line above — and local zoning decides where a tiny house can go at all, so confirm that first.
