What types of homes are usually under 400 square feet?

This range includes longer tiny houses on wheels, smaller park model homes, micro cabins, and some ADUs. THOWs near the top of the range often have a main-floor bedroom or extra loft space. Park models may offer slightly wider interiors but still stay under 400 square feet on the listing.

Is under 400 square feet enough for two people full time?

For many couples, yes. The extra square footage compared with sub-300 square feet builds usually means better kitchen layout, more closet space, and room for a desk or dining area. Read each listing carefully and confirm whether the home is certified, insulated for your climate, and legal to place where you plan to live.

How do tiny houses under 400 square feet compare on price?

Prices rise with size, finishes, and whether the home is new or used. Longer THOWs and park models under 400 square feet often list above the smallest micro builds but below larger park model homes. Each card shows the asking price so you can compare cost per square foot across listings.

Do listings under 400 square feet include land?

Most do not. The majority of listings are the home only, not land. A small number of foundation-built tiny homes may include a lot or sit in a tiny home community. Always confirm what is included with the seller before making an offer.
