    Subdivision 1. Adoption of code. Subject to sections 16B.59 to 16B.75, the commissioner
shall by rule and in consultation with the Construction Codes Advisory Council establish a code
of standards for the construction, reconstruction, alteration, and repair of buildings, governing
matters of structural materials, design and construction, fire protection, health, sanitation, and
safety, including design and construction standards regarding heat loss control, illumination, and
climate control. The code must also include duties and responsibilities for code administration,
including procedures for administrative action, penalties, and suspension and revocation of
certification. The code must conform insofar as practicable to model building codes generally
accepted and in use throughout the United States, including a code for building conservation.
In the preparation of the code, consideration must be given to the existing statewide specialty
codes presently in use in the state. Model codes with necessary modifications and statewide
specialty codes may be adopted by reference. The code must be based on the application of
scientific principles, approved tests, and professional judgment. To the extent possible, the code
must be adopted in terms of desired results instead of the means of achieving those results,
avoiding wherever possible the incorporation of specifications of particular methods or materials.
To that end the code must encourage the use of new methods and new materials. Except as
otherwise provided in sections 16B.59 to 16B.75, the commissioner shall administer and enforce
the provisions of those sections.
    The commissioner shall develop rules addressing the plan review fee assessed to similar
buildings without significant modifications including provisions for use of building systems as
specified in the industrial/modular program specified in section 16B.75. Additional plan review
fees associated with similar plans must be based on costs commensurate with the direct and
indirect costs of the service.
    Subd. 1a. Administration by commissioner. The commissioner shall administer and enforce
the State Building Code as a municipality with respect to public buildings and state licensed
facilities in the state. The commissioner shall establish appropriate permit, plan review, inspection
fees, and surcharges for public buildings and state licensed facilities.
    Municipalities other than the state having an agreement with the commissioner for code
administration and enforcement service for public buildings and state licensed facilities shall
charge their customary fees, including surcharge, to be paid directly to the jurisdiction by the
applicant seeking authorization to construct a public building or a state licensed facility. The
commissioner shall sign an agreement with a municipality other than the state for plan review,
code administration, and code enforcement service for public buildings and state licensed
facilities in the jurisdiction if the building officials of the municipality meet the requirements of
section 16B.65 and wish to provide those services and if the commissioner determines that the
municipality has enough adequately trained and qualified building inspectors to provide those
services for the construction project.
    The commissioner may direct the state building official to assist a community that has been
affected by a natural disaster with building evaluation and other activities related to building codes.
    Administration and enforcement in a municipality under this section must apply any optional
provisions of the State Building Code adopted by the municipality. A municipality adopting any
optional code provision shall notify the state building official within 30 days of its adoption.
    The commissioner shall administer and enforce the provisions of the code relating to
elevators statewide, except as provided for under section 16B.747, subdivision 3.
    Subd. 2. Enforcement by certain bodies. Under the direction and supervision of the
commissioner, the provisions of the code relating to electrical installations, plumbing, boilers,
high pressure steam piping and appurtenances, and ammonia refrigeration piping shall be enforced
by the Department of Labor and Industry. Fees for inspections conducted by the commissioner
shall be paid in accordance with the rules of the department. Under direction of the commissioner
of public safety, the state fire marshal shall enforce the State Fire Code as provided in chapter
299F. The commissioner shall adopt amendments to the mechanical code portion of the State
Building Code to implement standards for process piping.
    Subd. 3. Special requirements. (a) Space for commuter vans. The code must require that
any parking ramp or other parking facility constructed in accordance with the code include an
appropriate number of spaces suitable for the parking of motor vehicles having a capacity of seven
to 16 persons and which are principally used to provide prearranged commuter transportation
of employees to or from their place of employment or to or from a transit stop authorized by a
local transit authority.
    (b) Smoke detection devices. The code must require that all dwellings, lodging houses,
apartment houses, and hotels as defined in section 299F.362 comply with the provisions of section
    (c) Doors in nursing homes and hospitals. The State Building Code may not require that
each door entering a sleeping or patient's room from a corridor in a nursing home or hospital with
an approved complete standard automatic fire extinguishing system be constructed or maintained
as self-closing or automatically closing.
    (d) Child care facilities in churches; ground level exit. A licensed day care center serving
fewer than 30 preschool age persons and which is located in a belowground space in a church
building is exempt from the State Building Code requirement for a ground level exit when the
center has more than two stairways to the ground level and its exit.
    (e) Family and group family day care. Until the legislature enacts legislation specifying
appropriate standards, the definition of dwellings constructed in accordance with the International
Residential Code as adopted as part of the State Building Code applies to family and group
family day care homes licensed by the Department of Human Services under Minnesota Rules,
chapter 9502.
    (f) Enclosed stairways. No provision of the code or any appendix chapter of the code may
require stairways of existing multiple dwelling buildings of two stories or less to be enclosed.
    (g) Double cylinder dead bolt locks. No provision of the code or appendix chapter of the
code may prohibit double cylinder dead bolt locks in existing single-family homes, townhouses,
and first floor duplexes used exclusively as a residential dwelling. Any recommendation or
promotion of double cylinder dead bolt locks must include a warning about their potential fire
danger and procedures to minimize the danger.
    (h) Relocated residential buildings. A residential building relocated within or into a
political subdivision of the state need not comply with the State Energy Code or section 326.371
provided that, where available, an energy audit is conducted on the relocated building.
    (i) Automatic garage door opening systems. The code must require all residential buildings
as defined in section 325F.82 to comply with the provisions of sections 325F.82 and 325F.83.
    (j) Exit sign illumination. For a new building on which construction is begun on or after
October 1, 1993, or an existing building on which remodeling affecting 50 percent or more of the
enclosed space is begun on or after October 1, 1993, the code must prohibit the use of internally
illuminated exit signs whose electrical consumption during nonemergency operation exceeds 20
watts of resistive power. All other requirements in the code for exit signs must be complied with.
    (k) Exterior wood decks, patios, and balconies. The code must permit the decking
surface and upper portions of exterior wood decks, patios, and balconies to be constructed of
(1) heartwood from species of wood having natural resistance to decay or termites, including
redwood and cedars, (2) grades of lumber which contain sapwood from species of wood having
natural resistance to decay or termites, including redwood and cedars, or (3) treated wood. The
species and grades of wood products used to construct the decking surface and upper portions of
exterior decks, patios, and balconies must be made available to the building official on request
before final construction approval.
    (l) Bioprocess piping and equipment. No permit fee for bioprocess piping may be imposed
by municipalities under the State Building Code, except as required under section 326.47,
subdivision 1
. Permits for bioprocess piping shall be according to section 326.47 administered
by the Department of Labor and Industry. All data regarding the material production processes,
including the bioprocess system's structural design and layout, are nonpublic data as provided
by section 13.7911.
    Subd. 3a. Recycling space. The code must require suitable space for the separation,
collection, and temporary storage of recyclable materials within or adjacent to new or significantly
remodeled structures that contain 1,000 square feet or more. Residential structures with fewer
than four dwelling units are exempt from this subdivision.
    Subd. 3b. Radon code. The commissioner of labor and industry shall adopt rules for radon
control as part of the State Building Code for all new residential buildings. These rules shall
incorporate the radon control methods found in the International Residential Code appendix as the
model language, with necessary amendments to coordinate with the other adopted construction
codes in Minnesota.
    Subd. 3c. Window fall prevention device code. The commissioner of labor and industry
shall adopt rules for window fall prevention devices as part of the State Building Code. Window
fall prevention devices include, but are not limited to, safety screens, hardware, guards, and other
devices that comply with the standards established by the commissioner of labor and industry.
The rules shall require compliance with standards for window fall prevention devices developed
by ASTM International, contained in the International Building Code as the model language with
amendments deemed necessary to coordinate with the other adopted building codes in Minnesota.
The rules shall establish a scope that includes the applicable building occupancies, and the types,
locations, and sizes of windows that will require the installation of fall devices. The rules will
be effective July 1, 2009. The commissioner shall report to the legislature on the status of the
rulemaking on or before February 15, 2008.
    Subd. 4. Review of plans for public buildings and state licensed facilities. Construction
or remodeling may not begin on any public building or state licensed facility until the plans
and specifications have been approved by the commissioner or municipality under contractual
agreement pursuant to subdivision 1a. The plans and specifications must be submitted for review,
and within 30 days after receipt of the plans and specifications, the commissioner or municipality
under contractual agreement shall notify the submitting authority of any corrections.
    Subd. 5. Accessibility. (a) Public buildings. The code must provide for making public
buildings constructed or remodeled after July 1, 1963, accessible to and usable by persons with
disabilities, although this does not require the remodeling of public buildings solely to provide
accessibility and usability to persons with disabilities when remodeling would not otherwise
be undertaken.
    (b) Leased space. No agency of the state may lease space for agency operations in a
non-state-owned building unless the building satisfies the requirements of the State Building
Code for accessibility by persons with disabilities, or is eligible to display the state symbol of
accessibility. This limitation applies to leases of 30 days or more for space of at least 1,000
square feet.
    (c) Meetings or conferences. Meetings or conferences for the public or for state employees
which are sponsored in whole or in part by a state agency must be held in buildings that meet
the State Building Code requirements relating to accessibility for persons with disabilities. This
subdivision does not apply to any classes, seminars, or training programs offered by the Minnesota
State Colleges and Universities or the University of Minnesota. Meetings or conferences intended
for specific individuals none of whom need the accessibility features for persons with disabilities
specified in the State Building Code need not comply with this subdivision unless a person with a
disability gives reasonable advance notice of an intent to attend the meeting or conference. When
sign language interpreters will be provided, meetings or conference sites must be chosen which
allow hearing impaired participants to see their signing clearly.
    (d) Exemptions. The commissioner may grant an exemption from the requirements of
paragraphs (b) and (c) in advance if an agency has demonstrated that reasonable efforts were
made to secure facilities which complied with those requirements and if the selected facilities
are the best available for access for persons with disabilities. Exemptions shall be granted using
criteria developed by the commissioner in consultation with the Council on Disability.
    (e) Symbol indicating access. The wheelchair symbol adopted by Rehabilitation
International's Eleventh World Congress is the state symbol indicating buildings, facilities, and
grounds which are accessible to and usable by persons with disabilities. In the interests of
uniformity, this symbol is the sole symbol for display in or on all public or private buildings,
facilities, and grounds which qualify for its use. The secretary of state shall obtain the symbol and
keep it on file. No building, facility, or grounds may display the symbol unless it is in compliance
with the rules adopted by the commissioner under subdivision 1. Before any rules are proposed
for adoption under this paragraph, the commissioner shall consult with the Council on Disability.
Rules adopted under this paragraph must be enforced in the same way as other accessibility rules
of the State Building Code.
    (f) Municipal enforcement. Municipalities which have not adopted the State Building Code
may enforce the building code requirements for persons with disabilities by either entering into a
joint powers agreement for enforcement with another municipality which has adopted the State
Building Code; or contracting for enforcement with an individual certified under section 16B.65,
subdivision 3
, to enforce the State Building Code.
    Subd. 6. Energy efficiency. The code must provide for building new low-income housing in
accordance with energy efficiency standards adopted under subdivision 1. For purposes of this
subdivision, low-income housing means residential housing built for low-income persons and
families under a program of a housing and redevelopment authority, the Minnesota Housing
Finance Agency, or another entity receiving money from the state to construct such housing.
    Subd. 7. Access for the hearing-impaired. All rooms in the State Office Building and in
the Capitol that are used by the house of representatives or the senate for legislative hearings,
and the public galleries overlooking the house and senate chambers, must be fitted with assistive
listening devices for the hearing-impaired. Each hearing room and the public galleries must have
a sufficient number of receivers available so that hearing-impaired members of the public may
participate in the committee hearings and public sessions of the house and senate.
    Subd. 8. Separate metering for electric service. The standards concerning heat loss,
illumination, and climate control adopted pursuant to subdivision 1, shall require that electrical
service to individual dwelling units in buildings containing two or more units be separately
metered, with individual metering readily accessible to the individual occupants. The standards
authorized by this subdivision shall only apply to buildings constructed after the effective date
of the amended standards. Buildings intended for occupancy primarily by persons who are 62
years of age or older or disabled, or which contain a majority of units not equipped with complete
kitchen facilities, shall be exempt from the provisions of this subdivision.
