  1. The New 8th Edition of the Massachusetts State Building Code Tom Riley – Department of Public Safety Rob Anderson – Department of Public Safety A. Vernon Woodworth, AIA, LEED AP – R.W. Sullivan Engineering

  2. 780 CMR 8th Edition Base Code Disclaimer • This presentation attempts to familiarize users with the new 8th edition and specifically with what’s changed from the 7th edition. The information provided may have inaccuracies and cannot encompass all of the changes between the two editions of the building code. • This training presentation may be found at the DPS website.

  3. The 7th Edition Base Code + Embedded MA amendments = (Sold at State bookstore) Note: The code also references other MA codes (plumbing, electrical, etc.) and I-codes* which cover mechanical and energy requirements. *Can be purchased at www.iccsafe.org

  4. The 8th Edition uses I-codes MAAmendments + Note: The code also references other MA codes (plumbing, electrical, etc.)

  5. MSBC • Front-end Amendments

  6. Using the 8th Edition Base Code Example: How do I find energy requirements for building envelope sealing? • Go to chapter13 of IBC: IBC says to use IECC. • Found in section 502.4.3 of IECC. • Check MA amendments for chapter 13: it also says use IECC but with MA amendments. • Note: MA amendments in 13 are listed according to IECC section numbers and yes, section 502.4.3 has been amended!

  10. Chapter 1 Administration Organization • How did we get 25-sections of the 7th chapter 1 to fit into the 16-sections of the IBC chapter 1 and keep amendments to a minimum? • Reviewed every section of the 7th; found its’ corresponding location in 8th or added amendments if needed. • Deleted several topics not in use (Construction Materials Safety Board, for example) and moved embedded ‘convenience’ information to website. • Deleted MGL language; provided web link to MGL’s instead. • Deleted Special Regulations language (CSL, Native Lumber, etc.); referenced chapter 110 instead.

  11. Chapter 1: Administration IBC sections flow with project: • General • Applicability • Dept. of Building Safety (Building Official) • Duties of Building Official • Permits • Construction Documents • Submittal Documents • Temporary Structures and Uses • Fees • Inspections • Certificate of Occupancy • Service Utilities -reserved • Board of Appeals • Violations • Stop work order • Unsafe Structures and Equipment scope administration permitting construction problems

  12. Chapter 1: Administration • Key items • Townhouse requirements(101.2) clarified…hopefully! • 3-stories or less in one and two family code, appendix Z deleted. • Independent Structural Review (105.9) narrowed… • Required on only high rise and complex structures • Construction control(107.6) language tightened… • Alternative means and methods which deviate from prescriptive code requirements must be submitted to the building official for approval, separate from the plans. • IBC inspection language loosened (110.3) … • Construction inspection intervalsmay (not shall) include those set forth in sections 110.3.1 through 110.3.10 • Periodic Inspection Table 110 (was Table 106) revised: • Annual inspections of group residences removed. • Fire escapes included. • Temporary Certificate of Occupancy (111.3) : • IBC language adopted authorizing building official.

  13. Chapter 1: AdministrationReferenced Codes (101.4) • Specialized codes (M.G.L. c. 143, § 96): used in MA instead of or in conjunction with I-codes (IFC, IMC, IPC etc.). • Inspection of work under Specialized Codes by “individuals authorized by specialized codes”. • Specialized code work impacting building features subject to inspection by the building official. • Access enforced by the building official. See M.G.L. c. 22, § 13A. • Bunkers and magazines for explosive materials, flammable/combustible liquids and chemical process safety, defaults to 527 CMR and are enforceable by the head of the fire department rather thanthe building official. • Sheet Metal Regulations enforced by the building official. See M.G.L. c. 13, § 102. Specialized Codes (MGL 143 § 96) Plumbing 248 CMR Electrical 527CMR12 Access 521 CMR Fire Safety Code ? Fire Prevention 527 CMR Elevator 524 CMR Sheet Metal 271 CMR • Fire Prevention (101.4.5): Reference to the IFC or IMC for fire prevention issues shall be considered reference to 527 CMR. If 527 CMR does not address, then IFC or IMC shall apply. If a conflict regarding fire prevention requirements exists between 527 CMR and 780 CMR the more stringent standard shall apply. • Building code requirements in the IFC and IMC are made a part of 780 CMR and are enforceable by the building official. • Oil fired appliances governed by 527 CMR 4.00.

  14. Chapter 1: Administration Other items of note: • DDS Facilities (102.2.1): Additional safety features in one and two family dwellings for group residence do not change the building classification from one and two family. • Work exempt from permit (105.2): Now specifies painting…cabinetry…finish work and playground equipment. • Permit application (105.3): Indicate if licensed by a State care agency. • Electronic seal (107.1.1): Allowed, see DPL website: www.mass.gov/dpl • Inspection intervals (110.3) : The building official shall conduct inspections…which may include inspections set forth in Sections 110.3.1 through 110.3.10. • Lowest floor in flood zones (110.3): Certification must be submitted to BO that elevation is in compliance with section 1612.5 before work above that elevation proceeds • Temporary Occupancy (111.3): Key change is that this IBC section is not amended. Like the 7th edition the building official has the sole authority to issue a temporary certificate. The 8th does not require consultation with the fire official (7th edition language). • Unsafe structures (116.1) : Resurrected 6th edition language per DFS request.

  15. Chapter 2: Definitions • IBC definitions, some of which don’t exist in the 7th, were reviewed and retained. • MA unique definitions added: • Agriculture: as per MGL • Agricultural , Building: • Building Official: as per MGL • Design Flood: as per DEP/Appendix G • Design Flood Elevation: • High-Rise Building: 70 for MA vs 75 feet in IBC. • Jurisdiction: BBRS • Night Club: • Ordinance: means same as bylaw • Registered Design Professional, RDP: applies to MA PE’s and registered architects. • Specialized Codes: Just those listed in MGL 143 § 96 • Story Above Grade Plane: • Temporary Emergency Uses: • Temporary Overnight Shelter:

  16. Chapter 3: Use and Occupancy Overview: • In general, group homes, day care and related care facilities formerly in chapter 4 have been integrated into chapter 3. • Once classified, all requirements to be enforced by the BO are found in the main body of the code. • Special requirements and emergency evacuation requirements are covered by MA care agency regulations and enforced by the respective agency. • 7th • Chapter 4 • Group Residences • Day Care centers • Limited Group Residence • Detox. Facilities • Group Dwelling units 8th Chapter 3 Moved to

  17. Chapter 3: Use and Occupancy Changes and noted issues: • Day care: (305.2): MAcut-off age 2 yrs 9 mo vs IBC 2 yrs 6 mo. • Group homes (308.2): No longer in chapter 4. Caveats retained to ensure one and two family group homes with five or fewer residents are treated strictly as one and two family dwellings. Ability to evacuate during emergencies is care agency’s responsibility - BO only inspects for compliance with the building code. • I-2 and Residential care/assisted living facilities: (308.3)I-2 type facilities with up to 12 residents licensed or operated by DMH may be considered R-4 facilities. • Child care vs Day Care (308.5.2): To be determined if the term ‘child care’ is in error in this section and 310 of the IBC as these sections discuss care for less than 24 hours which is considered ‘Day Care’ elsewhere. • R-1 classification (310.1): Summer camps listed but requirements still in chapter 4. • R-2 classification (310.1): Includes day care of up to 10-children in an apartment and DMH licensed or operated units. • R-3 classification (310.1): Day care of up to 10 children allowed in a unit. Townhouses of more than 3-stories added to list with note that height and area and fire protection in accordance with R-2. DDS and DMH group type facilities also noted. • Definitions (310.2): • Boarding House references the MGL definition; • Congregate Care Facilities – definition added; • Residential Care/Assisted Living Facilities – Elder Affairs and DMH MGL’s cited. • Summer Camps- definition added.
