New Mexico has approved Appendix Q in the 2018 edition of the International Residential Code (IRC), which formally recognizes tiny homes as a legal housing option. This means that tiny homes are now recognized and regulated by the state building code, which defines a tiny house as a single-family home of 400 square feet or less, excluding lofts. The code also relaxes some general standards for such homes, making it easier for individuals to build and live in tiny homes in New Mexico.

It is important to note that while tiny homes are legal in New Mexico, there may be additional zoning and building regulations that vary by county and city. Prospective tiny home owners should always research and consult with local authorities to ensure that they are in compliance with all relevant laws and regulations. Nonetheless, the state’s recognition of tiny homes as a legal housing option is a promising step forward for those seeking a more sustainable and affordable way of living in New Mexico.
