Many education communities build and maintain cultural resource properties whose safety and sustainability objectives are informed by local adaptations of consensus products developed by the International Code Council (ICC) and the National Fire Protection Association (NFPA). We need to understand the ICC and NFPA product suites as a pair. For most real assets in the education industry they move “roughly” in tandem even though they are produced by different organizations for a different set of customers. Sometimes the out-of-step condition between NFPA and ICC permits subject matter experts on technical committees to make the best possible decisions regarding the safety and sustainability agenda of the interest group they represent; but not always.
Occupancy classification is always a first consideration and both the NFPA and the ICC have a claim to some part of this occupancy concept*. In the ICC suite we find code requirements for many “cultural places of worship” tracking in the following sections of the International Building Code (IBC):
Section 303 Assembly Group A-3
Section 305 Educational Group E
Section 308 Institutional Group I
Note that Sections 305 and 308 recognize the accessory and multi-functional nature of occupancy types in the education industry – i.e child care and adult care function can marge and be an accessory to a place of worship. The general rule in the IBC is that accessory religious educational rooms and religious auditoriums with occupant loads of less than 100 per room or space are not considered separate occupancies. Other standards developers are guided by this rule.







Close coupled to the IBC for this occupancy class is NFPA 909 Code for the Protection of Cultural Resource Properties – Museums, Libraries, and Places of Worship. From the document prospectus:
• This code describes principles and practices of protection for cultural resource properties (including, but not limited to, museums, libraries, and places of worship), their contents, and collections, against conditions or physical situations with the potential to cause damage or loss.
• This code covers ongoing operations and rehabilitation and acknowledges the need to preserve culturally significant and character-defining building features and sensitive, often irreplaceable, collections and to provide continuity of operations.
• Principles and practices for life safety in cultural resource properties are outside the scope of this code. Where this code includes provisions for maintaining means of egress and controlling occupant load, it is to facilitate the evacuation of items of cultural significance, allow access for damage limitation teams in an emergency, and prevent damage to collections through overcrowding or as an unintended consequence of an emergency evacuation.
• Library and museum collections that are privately owned and not open to the public shall not be required to meet the requirements of this code.







Since we are hard upon release of the 2021 Edition of NFPA 909 let us take a backward look at the current (2017) version of NFPA 909 Code for the Protection of Cultural Resource Properties – Museums, Libraries, and Places of Worship. Chapter 14 covers “Museums, Libraries and their Collections”. Chapter 15 covers “Places of Worship”
The 2025 Edition is now open for public input. Let us pick through proposals for the 2021 Edition to inform our approach to its improvement by referencing the technical committee transcripts linked below:
Public Input Report: January 12, 2023
N.B. We find committee response (accepted in principle) to Standards Michigan proposal to articulate conditions in which places of worship and libraries are used as community disaster relief support facilities. We consider this a modest “code win”.
Circling back to the ICC suite we find elevated interest in hardening community owned facilities to tornadoes, hurricane and floods and other storm related risk in the structural engineering chapters of the International Building Code.

“We need the sense of the sacred, and the sense that things transcend our grasp.
We need to know that we are dependent on others,
and that the condition of our existence is the existence of others.”
The founding of many education communities is inspired by faith communities. In many of them the place of worship was the very first building. College and university chapels are central places of worship for students, staff and faculty, and provide a space for solitude and reflection. A place for feeling at home in the world.
International Building Code | Section 303.4 Assembly Group A-3
There are several hundred technical standards, or parts of standards, that govern how churches and chapels are made safe and sustainable. Owing to innovations in construction, operation and management methods, those standards move, ever so slightly, on a near-daily basis. They are highly interdependent; confounded by county-level adaptations; and impossible to harmonize by adoption cycle. That movement tracked here as best we can within the limit of our resources and priorities. That’s why it’s best to simply click into our daily colloquia if you have a question or need guidance.

Abstract. Insights into the history and future of western civilization are found by applying information theory to the acoustical communication channel (ACC) of its worship spaces. Properties of the ACC have both influenced and reflected the choice of message coding (e.g., speech or music) at various times. Speech coding is efficient for acoustically dry ACCs, but hopeless for highly time-dispersive ACCs. Music coding is appropriate for time dispersive (reverberant) ACCs. The ACCs of synagogues, early Christian house churches, and many Protestant churches are relatively acoustically “dry” and thus well suited to spoken liturgies.
The spoken liturgy, dominant in synagogues, was carried over to early Christian churches, but became unworkable in Constantinian cathedrals and was largely replaced with a musical liturgy. After a millennium, the cathedral acoustic was altered to suit the doctrinal needs of reformation churches with its renewed emphasis on the spoken word. Worship forms continue to change, and the changes are reflected in the properties of the ACC. The pulpits of electronic churches may be evolving into radio and television performance spaces and naves into worshipers’ living rooms.

WEBCAST Committee Action Hearings, Group A #2
2024 International Building Code: Chapter 3 Occupancy Classification and Use
In the International Code Council catalog of best practice literature we find the first principles for safety in places of worship tracking in the following sections of the International Building Code (IBC):
“303.1.4: Accessory religious educational rooms and religious auditoriums with occupant loads less than 100 per room or space are not considered separate occupancies.” This informs how fire protection systems are designed.
Section 305 Educational Group E
“305.2.1: Rooms and spaces within places of worship proving such day care during religious functions shall be classified as part of the primary occupancy.” This group includes building and structures or portions thereof occupied by more than five children older than 2-1/2 years of age who receive educational, supervision or personal care services for fewer than 24 hours per day.
Section 308 Institutional Group I
“308.5.2: Rooms and spaces within places of religious worship providing [Group I-4 Day Care Facilities] during religious functions shall be classified as part of the primary occupancy. When [Group I-4 Day Care Facilities] includes buildings and structures occupied by more than five persons of any age who receive custodial care for fewer than 24 hours per day by persons other than parents or guardians, relatives by blood, marriage or adoption, and in a place other than the home of the person cared for.
Tricky stuff — and we haven’t even included conditions under which university-affiliated places of worship may expected to be used as community storm shelters.















2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE
Public response to Committee Actions taken in Orlando in April will be received until July 8th.
Because standard development tends to be a backward-looking domain it is enlightening to understand the concepts in play in previous editions. The complete monograph of proposals for new building safety concepts for places of worship for the current revision cycle is linked below:
2021/2022 Code Development: Group B
A simple search on the word “worship” will reveal what ideas are in play. With the Group B Public Comment Hearings now complete ICC administered committees are now curating the results for the Online Governmental Consensus Vote milestone in the ICC process that was completed December 6th. Status reports are linked below:
2018/2019 Code Development: Group B
Note that a number of proposals that passed the governmental vote are being challenged by a number of stakeholders in a follow-on appeals process:
A quick review of the appeals statements reveals some concern over process, administration and technical matters but none of them directly affect how leading practice for places of worship is asserted.
We are happy to get down in the weeds with facility professionals on other technical issues regarding other occupancy classes that are present in educational communities. See our CALENDAR for next Construction (Ædificare) colloquium open to everyone.
