ICC IBC-2021

2021 International Building Code

This code applies to all buildings except detached one- and two-family dwellings and townhouses up to three stories. The 2021 IBC contains many important changes such as: Puzzle rooms (escape rooms) are now defined and regulated as special amusement areas, requiring compliance with Section 411 and special means of egress requirements. For the purposes of determining the allowable number of control areas in a building, each portion separated by one or more fire walls is now considered as a separate building. In Group E occupancies, enhanced classroom acoustics in compliance with ICC A117.1 are to be provided in all classrooms having of volume of 20,000 cubic feet or less. The requirements for metal composite materials and systems (MCM) installed on the exterior walls of Types I, II, III and IV construction were simplified and sprinkler allowances were deleted The use of intermodal shipping containers as buildings is now specifically addressed through provisions intended to supplement existing applicable IBC requirements. Automatic sprinkler protection is now required in Group S-2 open parking garages where any fire area exceeds 48,000 square feet. The 2017 edition of ICC A117.1 was adopted. Parapets of a minimum height are now required for aggregate-surfaced roofs to prevent blow-off. Mixed occupancy buildings with assembly spaces are placed in Risk Category III when the total public assembly occupant load is greater than 2500 people. The 2021 IBC snow map is updated to match ASCE 7-16 snow maps by adding a reference to ASCE 7 snow tables in states with large case study areas. Secondary rain loads are updated to be consistent with ASCE 7. Special inspection requirements were added to address the anchorage and connection of mass timber structural elements. Installation of firestop, fire-resistant joint systems and perimeter fire barrier systems in residential-use buildings now requires special inspection in Group R fire areas having an occupant load exceeding 250 people. Frost protection for egress doors was added to the foundation requirements. ACI standards ACI 117 and ITG 7 were added by reference to provide acceptable tolerances for concrete construction. Three new types of construction (Types IV-A, IV-B, and IV-C) allow mass timber buildings of taller heights, more stories above grade, and greater allowable areas compared to existing provisions for heavy timber buildings.


2021 International Existing Building Code

Encourages the use and reuse of existing buildings. This code covers repair, alteration, addition and change of occupancy for existing buildings. and historic buildings, while achieving appropriate levels of safety without requiring full compliance with the new construction requirements contained in the other I-Codes. Key changes in the 2021 IEBC include: For storm shelters, the required occupant capacity is now limited to the total occupant load of the classrooms, vocational rooms and offices in the school while the maximum distance of travel was deleted. When significant portions of a building’s exterior wall coverings or exterior wall envelope are added or replaced, they must comply with the requirements of Chapters 14 and 26 of the IBC. Snow loads must be addressed during repair of substantial structural damage regardless of whether the damage was a result of snow. Additions, Level 3 alterations and Changes of occupancy in Educational occupancies are now required to meet the enhanced classroom acoustic requirements of Section 808 of ICC A117.1. Additional equipment may be added to a roof without a full structural analysis when the equipment weighs less than 400 pounds and is less than 10 percent of the total roof dead load. With a change of occupancy, a seismic analysis is required for a Group S or Group U occupancy changing to a new occupancy. Furniture, such as office cubicles, reception desks or smaller bookcases, are exempt from a permit and not intended to be a Level 2 alteration. Sprinkler requirements for Level 2 and Level 3 alterations are revised for higher hazard areas. The 2021 IEBC Redline is still in development and you will received an updated PDF once completed.

The maximum allowable fenestration U-factors in Table R402.1.2 (for the prescriptive compliance path) for climates zones 3 through 8 have been reduced from the values in the 2015 edition. The ICC/RESNET 380 standard has been included as one of standards that can be used for determining the air leakage rate of a building or dwelling unit. The Energy Rating Index compliance alternative index values have been increased slightly however, the method for determining an index is now required to be in accordance with standard ICC/RESNET 301. Revisions to interior and exterior lighting power budgets and better clarity for lighting controls. Clarity that regardless of design methodology, system commissioning is required. New limits on heated or cooled vestibules. Mechanical provisions reorganized based on equipment type rather than design methodology.

ICC IFC-2021

Flame propagation performance of permanently installed artificial combustible vegetation is required to be verified when exceeding certain heights located on roofs or in close proximity to buildings. Provisions for emergency responder communication were revised to reflect the expansion of such systems beyond radios and the need for increased performance of such systems. Sprinkler requirements for the storage, manufacture and sale of upholstered furniture and mattresses were updated and clarified. Part of this update is a new exception for single-story self-storage facilities accessed directly from the exterior. An automatic sprinkler system is now required for open parking garages exceeding a certain fire area threshold. The requirements for energy storage system (ESS) were further refined to reflect the variety of new technologies and applications (in building and standalone) and the need for proper commissioning and decommissioning of such systems. A new chapter was added that provides clarification and specific requirements for the storage of distilled spirits and wines in barrels and casks. The provisions for construction fire safety were reorganized and expanded with an emphasis on the owner’s responsibilities. The new language requires a site safety plan and designation of a site safety director.


2021 International Fuel Gas Code

ICC IPC-2021

2021 International Plumbing Code

The 2021 IPC provides minimum regulations for plumbing facilities and provides for the acceptance of new and innovative products, materials, and systems. In October 2019, the Code Council released an independent study comparing model plumbing codes. It found that over a 12-year period, counties using the IPC saved $38 billion in construction costs, emitted 1,000,000 fewer tons of carbon dioxide, saw an additional 166,000 jobs, and saved 880 million feet of pipe. On average, a single-family home could save up to $4,000 in labor, materials and overhead compared to that same home built to other codes. To learn more about the IPC’s impact on construction, the economy and the environment, read the full report at www.iccsafe.org/IPC. Important changes in the 2021 IPC include: Multiple-user toilet facilities to serve all genders are now permitted. Two new methods for relining/rehabilitation of existing sewers are added.
