Advisory groups complete review of 2018 model codes
Technical Advisory Groups (TAGs) have completed their review of the 2018 model building codes.
The Construction Code Advisory Council (CCAC) established the advisory groups to review seven of the 2018
I-Codes and make recommendations for their potential adoption with amendments to Minnesota Rules. Three
additional TAGs reviewed administrative requirement, fire and building code compatibility and the structural
provisions of the I-Codes. The TAGs completed their review in March.
Review recommendations and comment
A report about the TAG review of the 2018 I-Codes was submitted May 15 to the CCAC, stakeholders and
interested parties to allow the opportunity for input prior to June 1. The CCAC will review and comment on the
report and stakeholder comments at its June 21 meeting. The meeting is open to the public and begins at 9 a.m.

License enforcement: Plumbing contractor fined $15,000
• A licensed plumbing contractor from Maple Grove, penalized in 2011 and 2014 for
failing to supervise its registered unlicensed employees and allowing employees with
expired registrations to perform plumbing work, was found in 2018 to be improperly
supervising its registered unlicensed employees. The contractor was censured and
ordered to pay a $15,000 fine of which $10,000 was stayed contingent on the contractor’s
compliance with requirements of the enforcement action.
• An unlicensed handyman from Bloomington was found to be engaged in plumbing
and residential building contracting work. He was ordered to cease and desist from all
unlicensed activity and fined $5,000, of which $4,500 was stayed based on compliance
with the licensing order.
• A licensed Andover electrical contractor was censured and fined $10,000, of which $8,000 was stayed, for its
failure to register its unlicensed electricians, failure to properly supervise its registered unlicensed electricians
and failure to properly apply for electrical permits.
• Two unlicensed individuals from Bemidji, who purchased, renovated and then resold manufactured homes,
were found to have engaged in unlicensed manufactured home sales, unlicensed residential building contracting,
unlicensed plumbing and failure to cooperate with investigators’ request for information. They were ordered to
cease and desist from all unlicensed activity and fined $12,500.
• A licensed residential building contractor from Minneapolis engaged in unlicensed plumbing and electrical
work on its projects. The contractor was fined $15,000, of which $12,000 was stayed contingent on no future

Registered unlicensed workers must report work experience at renewal
All registered unlicensed electricians, plumbers, elevator constructors and high pressure piping pipefitters
must submit a summary of their work experience for the previous year when they renew their registration each
year. Report work experience on a form signed by the responsible licensed individual (master) for the worker’s
employer. The completed form must then be uploaded with the worker’s online registration renewal, emailed to
email@example.com or mailed. Forms are available at www.dli.mn.gov/ccld/FormsRegistration.asp
Failure to report work experience may result in a worker’s experience not being counted toward the minimums
required to take a journeyworker license exam.
Registered unlicensed electricians and power limited technicians must also complete two hours of DLI-approved
continuing education before renewing the registration. Renewing a registration without continuing education
may result in suspension of the registration and a fine of at least $250.

aspx. Employers do not report work experience to us. Employers are required to track work experience, but it is
the responsibility of the worker to make sure their experience is reported.
Contact us at firstname.lastname@example.org or 651-284-5031.
Subcontractors must be registered or licensed with DLI
All contractors who provide commercial or residential building construction
or improvement services must either be licensed by DLI or registered in the
Construction Contractor Registration Program.
Why contractor registration?
The Contractor Registration Program helps DLI and other state agencies
investigate worker misclassification. Misclassification occurs when a
contractor has employees but treats them as independent contractors.
Instead of providing workers’ compensation and unemployment insurance and withholding payroll and FICA taxes,
some employers pay their workers cash or give them 1099s instead of W-2s, denying them the rights and benefits that
employees are entitled to under state and federal laws.
An individual worker or owner of a business cannot be treated as an independent contractor unless they are licensed
by DLI or registered in the Contractor Registration Program, and they meet all nine factors of the nine-factor test
(www.dli.mn.gov/CCLD/register.asp). An owner of a business entity is presumed to be an employee and not an
independent contractor if that business entity is not registered with the department and registration is required.
Verify a registration
Check a license or registration at https://secure.doli.state.mn.us/lookup2/licensing.aspx. All contractor registrations
begin with the letters “IR” and are followed by six digits.

Minnesota Plumbing Code frequently asked questions and answers
Is there a maximum allowable hot water heater/storage temperature or thermostatic setting on a water
heater? What are the temperature limitations for various plumbing fixtures?
Except for point-of-use temperature limitation on plumbing fixtures listed below, there is no requirement in
the Minnesota Plumbing Code that addresses temperature in hot water storage or temperatures in domestic hot
water distribution systems. Temperatures in domestic hot water storage and hot water distribution systems must
be designed for the intended application and be installed and maintained in accordance with the design and
manufacturer’s installation instructions and recommendations.
Hot water storage designs should also consider a temperature that minimizes Legionella bacteria growth. More
information about Legionella management plans for building water systems is at
To address scalding concerns, the Minnesota Plumbing Code includes maximum thermostatic mixing valve
temperatures for point-of-use protection:
Fixture Maximum mixed temperature Control valve standards
bathtubs and whirlpools* 120F ASSE 1070
bidets 110F ASSE 1070
lavatories in public restrooms 110F ASSE 1070
showers and tub-showers 120F ASSE 1016 or ASME A112.18.1/
gang showers** 120F ASSE 1069
1. Water heater thermostats are not considered a control for meeting these requirements.
2. A thermostatic mixing device listed to Standard ASSE 1017 is not acceptable for meeting these requirements.
* Except where protection is provided by an approved combination tub/shower valve.
** This is a single temperature-controlled water supply line for individual or multiple showers where users have
no control of temperature adjustments.
Can an indirect waste receptor like a standpipe be installed under a kitchen cabinet or similar with doors,
for receiving indirect waste? Does this installation meet the requirements of “readily accessible” and the
restriction on cupboards under Minnesota Plumbing Code, Section 804.1?
Yes. The definition of “readily accessible” in Minnesota Plumbing Code, Section 203.0, means having a direct
access without the necessity of removing a panel, door or similar obstruction. Therefore, opening a cabinet door
is considered readily accessible since the door is opened without the use of tools. In addition, a cabinet below
a plumbing fixture where plumbing piping exists is not considered a cupboard. See Minnesota Plumbing Code
Sections 802.1 and 804.1 for additional requirements and approvals of indirect waste receptors.
Can any purple primer be used for solvent cement joints in PVC pipe and fittings for drain, waste and vent
No. Purple color primer must be listed to ASTM F656 to comply with the Minnesota Plumbing Code, Section
705.7.2. Purple primer can be verified for compliance with ASTM F656 by checking the listing identification
label on the product.

Minnesota Building Code frequently asked questions and answers
When a building’s occupancy classification is changed, must the building be brought up to current building
code requirements for new construction?
Typically no. Through the “prescriptive compliance method” and with the approval of the building official, the
Minnesota Conservation Code for Existing Buildings allows a change of occupancy to an equal or lower life
safety and fire risk hazard without requiring major changes to the building systems. As a result of modifications,
existing conditions may not be less conforming to the current code than before the changes were made. This is the
easiest and most cost-effective compliance method.
Through the “work area compliance method,” changes in occupancy to higher hazard groups may be
accomplished, in many cases with reduced requirements to the building upgrades.
FIRE PROTECTION SPRINKLING
When are fire sprinklers required in a building?
There are three typical considerations in new construction when a building is required to be sprinkled:
1. If a municipality has adopted Minnesota Rule 1306 and the change of occupancy is within the scoping.
2. Where the occupancy has special requirements [Minnesota State Building Code (MSBC), Section 903].
3. To achieve an increase in allowable floor area or building height (MSBC, Chapter 5).
By dividing the building with fire barriers (Section 707.3.10), separate fire areas are created and sprinkling may
be avoided due to building compartmentalization (Section 903). By dividing a building with fire walls, separate
buildings are created and sprinkling may be avoided due to reduced building size (Chapter 5 and Section 903).
What is the difference between a fire wall and a fire barrier?
Fire walls must have sufficient structural stability under fire conditions to allow collapse of construction on either
side without collapse of the wall. They must also extend beyond the roof and beyond the exterior walls or meet
exceptions. Fire barriers do not have structural stability requirements, nor are they required to extend beyond the
roof deck or exterior walls.
When an existing building has a change in occupancy that requires the new occupancy to be sprinkled, does
the entire building need to be sprinkled? Not necessarily.
Change in occupancy to an equal or lower fire and life safety hazard level: The building official may approve
the change in occupancy without requiring sprinkling through the Minnesota Conservation Code for Existing
Buildings using the prescriptive compliance method. This is possible even if the occupancy would require
sprinkling if constructed as new. Minnesota Rule 1306 has provisions for existing buildings and would override
Minnesota Rule 1311 if adopted locally.
Change in occupancy to a higher fire and life safety hazard level:
• The provisions for sprinkling found in the MSBC Chapter 5 apply to the building, and provisions in MSBC
Section 903 apply where the new occupancy group occurs.
• Sprinkler requirements expand to the means of egress system on the floor where the change of occupancy occurs
when there are multiple tenants on the floor, or the means of egress on that floor serves more than 30 occupants.
• When the change of occupancy work area expands to more than 50-percent of the floor area, the entire floor
must be sprinkled with the exception of separate tenant spaces.
• When the work area expands to more than 50-percent of the total building area, high-rise buildings must be
sprinkled in all work areas, and waste and linen chutes must be sprinkled.

New electrical codes and standards bulletins available
Bulletin: Livestock Waterers and Equipotential Planes
The National Electrical Code (NEC) requires installation of an equipotential bonding plane where livestock
can stand while accessing metallic equipment. An equipotential plane is an area where a wire mesh or other
conductive elements are embedded in or placed under concrete, bonded to all metal structures and fixed
nonelectrical equipment that may become energized, and connected to the electrical grounding system to
minimize voltage differences within the plane and between the plane, the grounded equipment and the earth.

Bulletin: Fuel Dispensing: Installations, Retrofits and Replacements
Special disconnecting requirements at motor fuel dispensing facilities ensure safety for personnel and station
equipment during emergencies, maintenance and service activities. Generally, the purpose of the disconnecting
requirements is to remove any possibility of remotely starting the fuel dispenser(s) which could accidentally
release product, and to eliminate unintended electrical energy that could ignite any hazardous atmospheres.

LABOR AND INDUSTR Y
Don Nemeth, longtime electrical area representative, retires
After 27 years of dedicated service to Minnesota as a DLI electrical area representative, Don Nemeth retired
June 1, 2018. His work area included counties in central and west-central Minnesota.
Nemeth has many decades of electrical industry service as an electrician, electrical contractor, electrical
inspector and electrical instructor. His dedication and contributions to the electrical industry and electrical
inspection have been extraordinary. Nemeth rarely leaves home without a copy of the National Electrical
Code, so even in retirement he most likely will remain engaged in the electrical industry in some capacity. We
are very happy for him and wish him well in retirement.
