C405.12 Electrical for future use on new buildings with electrical services
1. Provide 2-inch conduit run up to attic for future photovoltaic systems.
2. Provide 2-inch conduit run into parking areas for future electric vehicle charging stations.

Chapter 1 <https://library.municode.com/mo/kansas_city/codes/code_of_ordinances?nodeId=PTIICOOR_CH1GEPR> [RE], SCOPE AND ADMINISTRATION is deleted. See Article I of this chapter.
Table R402.4.1.1. Under 'Walls'. Amend first sentence to read: "Corners and headers shall be sealed and the junction of the foundation and sill plate shall be sealed."
R403.3.7, Exception. In IRC projects building framing cavities may be used as ducts or plenums where sealed to prevent leakage through the thermal envelope.
R404.4 Electrical for future use on new buildings with electrical services
1. Provide 2-inch conduit run up to attic for future photovoltaic systems.
2. Provide 2-inch conduit run into garage areas for future electric vehicle charging stations. Exception: If conduit run installed to attic or garage includes wiring that is capable of handling the electrical load for the intended use provided in number 1 or number 2 above, the conduit does not need to meet the 2-inch requirement.
The following sections are amended /added to the referenced model code:
R401.2 Application. Amend to read: “Residential buildings shall comply with Section R401.2.5 and one of Sections R401.2.1, R401.2.2, R401.2.3, or R401.2.4; OR residential buildings shall comply with Section R401.2.6 only.”
R401.2.6 KCMO Compliance Path.
The KCMO Compliance Path requires compliance with Section R409.
R409 KCMO Compliance Path:
1. Submit a Home Energy Rating System (HERS) “Projected Report” based on the building plans showing an index score of 60 or better (better means a score of 60 or lower) by a RESNET certified Energy Rater with each permit application, along with a statement by the applicant that they are utilizing the KCMO Compliance Path.
2. 3rd Party Inspections and Testing performed during construction by a RESNET certified Energy Rater as required to generate a HERS Index number per ANSI/RESNET/ICC Standard 301 and required to be submitted prior to Temporary or Full Certificate of Occupancy, including but not limited to:
a. Insulation Inspection(s)
b. Duct Leakage Testing
c. Whole House Leakage Testing
3. As a condition of Temporary or Full Certificate of Occupancy, verify the score of 60 or lower by submitting a Final RESNET Certified Compliance report including the RESNET Registry ID by a RESNET certified Energy Rater.
4. As a condition of Temporary or Full Certificate of Occupancy, post a permanent certificate inside the building which lists:
a. the predominant R-values of insulation installed in ceilings, roof, wall, and foundation components;
b. the U-factors and solar heat gain coefficient (SHGC) of fenestration;
c. the results of the duct and whole house leakage tests;
d. the types, sizes and efficiencies of heating, cooling and service water-heating equipment; and
e. if on-site photovoltaic panel systems have been installed, the array capacity, inverter efficiency, panel tilt and orientation.
5. The building thermal envelope shall be greater than or equal to levels of efficiency and solar heat gain coefficients in Table R402.1.1 or R402.1.3 of the 2009 International Energy Conservation Code. The prevalent values from such Table R402.1.1 are as follows:
|
Fenestration U-Factor |
Skylight U- Factor |
Ceiling R- Value |
Wood Frame Wall R-Value |
Mass Wall R-Value |
Floor R- Value |
Basement Wall R- Value |
Slab R- Value & Depth |
Crawl Space Wall R-Value |
|
0.35 |
0.60 |
38 |
13 |
5/10 |
19 |
10/13 |

(see 2009 IECC for full tables, footnotes, and alternatives)
6. Air Barrier and Insulation Installation Criteria are per Table R409.1 (attached)
7. The rated design must meet the requirements of the sections indicated within Table R409.2 (attached)
When utilizing this R409 KCMO Compliance Path in conjunction with a Master Building Plan, the submitted HERS Projected Report must contemplate the most energy intensive combined variables of the plan options to include directional orientation. Subsequent builds of the same Master Building Plan are not required to repeat item 1.
No additional documentation shall be required for plan review and/or permitting to verify energy code compliance under this R409 KCMO Compliance Path.
R502 Additions. Amend to read: Additions shall be in accordance with Section R502.2 or R502.3. New additions and change of space conditioning projects may use any one of the three exceptions listed under Section R502.2 Change in Space Conditioning or may choose to use the R409 KCMO Compliance Path to be brought into full compliance with this code.”
Section 2. That previously approved Buildings Plans under the KCMO Energy Code shall have an opportunity to change to the R409 KCMO Compliance Path if so designated in writing and with the submission of required documents outlined in Section 1 within 30 days of the effective date of this ordinance.
Section 3. That previously approved Building Plans that were submitted as complete applications prior to September 29, 2023 (the mandatory implementation date of Ordinance) and subsequently approved by the City, are eligible for use and permits when using the R409 KCMO Compliance Path. In such instances, applicant shall submit a letter detailing the previously approved Building Plan they are using, and that any conflicting energy notes on that plan are now voided and replaced with the details of the documentation, inspections and testing required for the R409 KCMO Compliance Path as outlined in Section 1.
Further, regardless of chosen compliance path, all residential plan reviews are subject to City Code Section 2-2300, Permitting Standards.
Section 4. That the City may endeavor to create a systematic method to reduce the HERS score required in R409 KCMO Compliance Path. Such reductions shall occur no more than once every three years from the effective date of this Ordinance, shall be published at least one year in advance of their effective date(s), shall not exceed a 3 HERS-point reduction over any 3-year period from the prior score, and shall be based on analyzing data from the prior time period’s actual HERS scores.
