Capital letters or bold & italic numbers indicate new material to be added to existing law.
Dashes through the words or numbers indicate deletions from existing law. construction or installation of a factory-built nonresidential structure, a
factory-built residential structure, or a factory-built tiny home
(factory-built structure), the state plumbing board, the state electrical
board, and the state fire suppression administrator do not have jurisdiction
over and their rules do not apply to a factory-built structure.
On or before July 1, 2026, the advisory committee on factory-built
structures (advisory committee) is required to develop regional building
codes for factory-built structures and implementation requirements and
submit the recommended codes to the board.
On or before July 1, 2026, the board must adopt rules:
! Implementing regional building code recommendations
from the advisory committee that account for local climatic
and geographic conditions for the construction and
installation of factory-built structures, which supersede any
conflicting ordinance, code, regulation, or other law of a
local government unless the local government adopts the
rules of the board;
! Covering the implementation requirements developed by
the advisory committee, including authorizing a local
government certified by the division of housing (division)
to perform inspections of factory-built structures on behalf
of the division and registration, responsibility, and
accountability requirements for a manufacturer, installer,
seller, or general contractor who develops the installation
site or completes the construction of a factory-built
structure at the installation site;
! Covering electrical, plumbing, or fire suppression activity
required to undertake or complete the construction or
installation of a factory-built structure;
! Allowing the division to contract for third-party review and
approval of a final design plan for a factory-built structure
on behalf of the division;
! Allowing the division to create a process for vetting and
approving the ability of a third party to review and approve
a final design plan for a factory-built structure on behalf of
the division; and
! Requiring the division to cause an audit to be performed on
a third party that reviews and approves design plans.
On or before July 1, 2026, the advisory committee is required to conduct
a study on behalf of the division about whether the international building
code or residential code standards that apply to site requirements should
be incorporated into state statutes and rules and to determine whether the
state should regulate non-factory-built components that are connected to
a factory-built structure at the installation site and are currently under
local jurisdiction. The division is required to deliver the study to the board
002
-2- when complete.
A county or municipality may not:
! Enact a regulation that excludes factory-built structures and
manufactured homes from the county or municipality;
! Impose more restrictive standards on factory-built
structures and manufactured homes than those that the
county or municipality applies to site-built homes in the
same residential zones in the county or municipality; or
! Enact or enforce a regulation, law, or ordinance affecting
the installation or construction of a factory-built structure
or manufactured home.
A county or municipality may:
! Enact land use regulations to the extent that the regulations
are applicable to existing housing or structures or new
site-built housing in the county or municipality; and
! Enact a building code provision for unique public safety
requirements unless the provision applies to a factory-built
structure or manufactured home.
A county or municipality must comply with the requirements established
by the division for factory-built structures and by the United States
department of housing and urban development for manufactured homes.
The bill requires the state treasurer to transfer $600,000 on July 1,
2025, from the innovative housing incentive program fund to the building
regulation fund.
Be it enacted by the General Assembly of the State of Colorado:1
SECTION 1. Legislative declaration. (1) The general assembly2
finds and declares that:3
(a) Coloradans are overwhelmingly burdened with the cost of4
housing;5
(b) Forty-five percent of renters, 329,000 residents, spend more6
than 30% of their income on rent;7
(c) A household in Colorado must earn at least $70,840 annually8
to afford the median rent of $1,771 without being cost-burdened; 9
(d) To purchase a median-priced home, which is $550,300, with10
a 20% down payment, and avoid being cost-burdened, a household must11
002-3- earn $129,178 annually;1
(e) The average cost of construction of a new home as of2
November 2024 was approximately $483,000, which is an increase from3
$419,000 in 2023;4
(f) In 2021, the general assembly enacted House Bill 21-1329,5
which directed the executive committee of the legislative council to create6
a task force to meet during 2021 and issue a report with recommendations7
to the general assembly and the governor on policies to create8
transformative changes in the area of housing;9
(g) In 2022, the general assembly enacted House Bill 22-1282,10
which authorized investment in companies pursuing innovative11
construction methods, resulting in the establishment of the innovative12
housing incentive program;13
(h) Innovative housing incentive program investments are14
intended to create new housing units, which lower housing costs and15
encourage innovation; and16
(i) Off-site construction partners participating in the innovative17
housing incentive program, including modular manufacturers, have18
expressed concerns that regulatory barriers are preventing intended19
growth in housing units, reducing the cost and time-saving potential of20
off-site construction.21
(2) Therefore, the general assembly further finds and declares that22
it seeks to address the shortage and cost of housing by enacting regional23
standards for factory-built structures, rather than standards related to a24
specific address, which will increase the supply of housing and lower25
housing costs by lowering the cost of factory-built housing construction26
and encouraging partners to take advantage of the economies of scale27
002
-4- afforded through factory-built construction.1
