TO: The Honorable Mayor and City Council Members
FROM: Michael C. Van Milligen, City Manager
SUBJECT: Adoption of the 2015 International I-Codes
DATE: June 1, 2016
The City of Dubuque has traditionally adopted the new International I-Codes every three
years. The adoption of the 2015 International I-Codes allows the City's inspection staff
to properly perform their duties during the plan review process, field inspections, and
upon completion issuing the Certificate of Occupancy, making sure all structures are
safe and meet minimum code requirements. The City of Dubuque will also benefit from
the adoption of the new I-Codes through the Insurance Services Organization (ISO)
Building Code Effectiveness Grading Schedule, which provides communities with an
overall score based on the effectiveness of adopted Building Codes. This score is then
analyzed by insurance companies and others to help determine property insurance
rates locally.
Building Services Manager Todd Carr recommends City Council adoption of the
following 2015 International I-Codes:
1. 2015 International Residential Code
2. 2015 International Building Code
3. 2015 International Mechanical Code
4. 2015 International Plumbing Code
5. 2015 International Fuel Gas Code
6. 2015 International Energy Conservation Code
I concur with the recommendation and respectfully request Mayor and City Council
approval.

FROM: Todd Carr, Building Services Manager
SUBJECT: Adoption of the 2015 International ]-Codes
DATE: June 1st, 2016
Introduction:
The purpose of this memorandum is to provide you with information and request
adoption of the 2015 International I-Codes to replace our current 2012 International (-
Codes. The following 2015 International I-Codes are proposed to be adopted.
1. 2015 International Residential Code
2. 2015 International Building Code
3. 2015 International Mechanical Code
4. 2015 International Plumbing Code
5. 2015 International Fuel Gas Code
6. 2015 International Energy Conservation Code
Background: The City of Dubuque has traditionally adopted the new International (-
Codes every three years. The International Code Council who composes the I-Codes
every three years works with registered voting members from many different private and
public sectors during the adoption process of the new I-Codes. As a group they review
the Codes every three years, taking into consideration many different factors as they
amend, delete, change, or alter existing code language along with composing new code
language as needed.
Discussion: The adoption of the 2015 International I-Codes allows our inspection staff
to properly perform their duties throughout the plan review process, field inspections,
and upon completion issuing the Certificate of Occupancy, making sure all structures
are safe and meet minimum code requirements. The City of Dubuque will also benefit
from the adoption of the new I-Codes through the ISO Building Code Effectiveness
Grading Schedule, which provides communities with an overall score based on the
effectiveness of adopted Building Codes. This score is then analyzed by insurance
companies and others to help determine property insurance rates locally.
Service People Integrity Responsibility Innovation Teamwork
Conclusion: The adoption of the 2015 International I-Codes will replace our currently
adopted 2012 International I-Codes.
Action Step: I respectfully recommend the adoption of the new 2015 International (-
Codes.
I request that the ordinance is reviewed and forwarded to the City Council for
consideration and approval. Please let me know if you have any questions.
