Summary
A tiny home built to the state's certified program, no larger than four hundred square feet, permanently on a chassis and connected to public water and sewer, qualifies as a single-family detached dwelling in the Town of Parker under Section 13.02.020, but Parker's accessory dwelling unit ban means that same tiny home cannot be sited as a second unit on an existing lot.
Tiny home means a structure that (1) is permanently constructed on a vehicle chassis, (2) is designed for long-term residency to a single household, (3) includes electrical, mechanical, or plumbing services that are fabricated, formed, or assembled at a location other than the site of the completed home, (4) is not self-propelled; (5) has a square footage of not more than four hundred (400) square feet, (6) is built to the International Residential Code as adopted by the Building Codes and Standards program within the Division of Housing, and is connected to public water and sewer. Colorado tiny homes will receive a metal plate insignia that certifies the tiny home is built to the codes and standards of the program. This use does not include manufactured homes, recreational park trailers (as defined in Section 24-32-902, C.R.S.), or recreational vehicles (as defined in Section 24-32-902, C.R.S.) ... (1)Accessory dwelling unit. Accessory dwelling units are prohibited in all districts. [3]
Full Breakdown
The Town of Parker's Land Development Ordinance recognizes tiny homes by name in its definitions chapter, Section 13.02.020. To count as a Town-recognized tiny home, a structure must be permanently built on a vehicle chassis, designed for long-term residency by a single household, assembled off-site with its electrical, mechanical, and plumbing systems, not self-propelled, no larger than four hundred square feet, built to the International Residential Code through Colorado's state tiny home certification program run by the Division of Housing's Building Codes and Standards program, and connected to public water and sewer; a compliant unit receives a metal plate insignia certifying it meets the program's codes.
The definition specifically excludes recreational park trailers and recreational vehicles as defined in Section 24-32-902, C.R.S., from counting as tiny homes for Town purposes. Because the definition of 'Dwelling, single-family detached' in the same section expressly includes tiny homes that meet either the Town's building code or federal manufactured-housing construction standards, a certified tiny home can serve as a lot's principal residence in zoning districts where single-family detached dwellings are permitted by right, such as SF1, SF2, and SF3. What a tiny home cannot do in Parker is double as a second dwelling on an already-developed lot: Section 13.05.050(d)(1) states flatly that accessory dwelling units are prohibited in all districts, and the LDO's definition of 'Dwelling unit, accessory' expressly includes detached tiny homes among the structures that ban covers.
A homeowner wanting a tiny home has to bring it in as the sole dwelling on its own platted lot, not as a backyard cottage behind an existing house.
Violations & Fines
Placing a tiny home on a lot as a second, accessory dwelling unit violates the outright ADU ban in § 13.05.050(d)(1), regardless of whether the unit itself meets the state's tiny-home certification standards in § 13.02.020. Occupying a structure that lacks the required International Residential Code compliance, connection to public water and sewer, or state insignia as a dwelling is likewise a Land Development Ordinance violation, subject to the Town's general fine of up to $499.00 per day under § 13.01.080(b)(1).
