Please post the following as written. " What Qualifies as a Tiny House

In the United States, a structure is generally considered a tiny house if it meets the following commonly used standards. These criteria are reflected in the International Residential Code (IRC), Appendix Q, and the definitions used by most builders, zoning boards, and housing organizations.

---

1. Size Requirement

The defining characteristic of a tiny house is its size.

400 square feet or less (excluding loft areas)

This is the threshold most frequently cited in building codes, industry guidelines, and planning documents.

Any dwelling larger than 400 sq. ft. is usually classified as a “small home,” “ADU,” “park model,” or similar, but not a tiny house.

---

1. Fully Functional Living Unit

A tiny house must operate as a complete dwelling. This includes:

A dedicated sleeping area (loft or main floor)

A kitchen or kitchenette with the ability to prepare food

A bathroom, at minimum with a toilet and a shower

Ventilation, heating, and appropriate insulation

Safe egress, such as proper doors and windows

Functional utilities, either grid-tied or off-grid systems (solar, water tanks, septic/composting toilet)

If a structure lacks these features, it is typically considered a shed, cabin, or accessory building — not a tiny house.

---

1. Structure Types Recognized as Tiny Houses

Tiny houses exist in two main forms:

Tiny House on Wheels (THOW)

Built on a trailer frame

Often regulated similarly to RVs

Designed for mobility but still constructed to residential standards

Tiny House on a Foundation

A permanent dwelling

Typically built under IRC standards or Appendix Q

May require permits depending on local zoning

Both types are considered tiny houses as long as they meet the size and livability criteria.

---

1. Appendix Q Standards (for foundation-built tiny homes)

IRC Appendix Q provides safety and construction rules specific to tiny homes, such as:

Reduced minimum ceiling heights

Loft sizing requirements

Approved ladder or staircase designs

Emergency escape openings for lofts

These guidelines help make tiny houses safe without forcing them to meet all full-size home requirements.

---

1. What Does Not Qualify as a Tiny House

The following structures are generally not classified as tiny houses:

Unfinished cabins

Storage sheds or shed conversions without plumbing

RVs or travel trailers (unless built and used as a tiny home)

Dwellings exceeding 400 sq. ft.

---

Summary

A tiny house is a fully functional residential dwelling that is 400 sq. ft. or smaller, built either on a foundation or on wheels, and equipped with the essential systems required for long-term habitation."
