Tiny House vs. RV: Which Actually Fits Your Plans

Tiny houses on wheels and RVs can look similar from the outside, but the legal classification underneath determines everything else: how you finance it, insure it, where you can park it long-term, and how it holds its value. This guide breaks down the real differences, based on our research of current certification standards and financing data.

1. Certification Is the Real Dividing Line

RVIA certification means a home was built to and inspected against NFPA 1192, the RV industry's construction and safety standard, covering wiring, plumbing, propane, and fire safety.^4,5 Certified units get a visible seal, typically near the entry door.⁵ An alternative program, NOAH certification, inspects every single unit that goes through it (rather than RVIA's random spot-check model) and explicitly welcomes DIY builders through a dedicated certification track.² Neither certification is legally required everywhere, but both matter enormously for financing, insurance, and campground or RV park access.^3,4

2. Construction Quality Is Not the Same Thing as Classification

Traditional RVs are mass-produced using lightweight materials to stay under vehicle weight limits: thin aluminum or fiberglass walls, plastic plumbing, and minimal wiring built for occasional weekend use, not full-time living.¹ Purpose-built tiny houses, even RVIA-certified ones, are generally built more like a house, with more durable materials suited to daily, long-term occupancy.¹

3. Financing Differs Sharply

4. Depreciation Favors Tiny Houses Long-Term

According to the RV Industry Association, a new RV loses 20–30% of its value in the first year alone, then continues depreciating 8–10% annually after that, similar to a car.¹ Tiny houses, particularly well-built ones on a foundation, tend to hold value better over a 10-year ownership horizon due to more durable construction and slower depreciation.¹

5. Cost Comparison

RVs generally cost less upfront but more over time, given faster depreciation, more frequent repairs, and higher insurance costs relative to a well-built tiny house.¹

6. Where You Can Legally Stay

RVs can park in RV parks and campgrounds, and sometimes on private property temporarily, but most areas limit continuous RV living to somewhere between 30 and 180 days in one spot.¹ Zoning treatment for tiny houses varies even more by jurisdiction. Always verify local rules before assuming either option is legal for full-time, long-term living at a specific location. See our builder due diligence guide and our sister site's placement and zoning resources before committing to either path.
