Tag approves multiplex appendix edits and EV parking updates, sends package to BFRW

Summary
The tag approved reorganized multiplex definitions, clarified means‑of‑egress terms and EV‑parking requirements and voted to send the combined R7.3/R7.4 package to the BFRW committee for public comment.
The Building Code Council tag on Jan. 13 advanced a reworked multiplex‑housing appendix that reorganizes definitions, clarifies means‑of‑egress terminology and embeds updated electric‑vehicle (EV) parking requirements. The tag voted to forward the updated multiplex package (R7.3 with R7.4.0.1 incorporated) to the BFRW committee for public comment.
John Hall presented an edited R7.3 that creates an appendix‑level definition section for multiplex‑specific terms (corridor, circulation path, exit passageway, exterior exit stairway). Hall and others offered simplified alternative definitions to avoid importing confusing IBC exit‑access/exit‑discharge terminology into the residential appendix; several tag members, including Jeremy Moore and Micah, supported the clarified options as more usable for plan reviewers and designers.
Members discussed energy‑code implications: a corridor that connects dwelling units internally can trigger a commercial energy review under the current energy code definition, which could unintentionally move a multiplex into a commercial energy review. Marcus and others noted an energy‑technical advisory amendment is in process to address this interplay; the tag agreed the topic could be refined during public comment and at BFRW.
On fire protection, members debated whether to point broadly to the International Fire Code (IFC) or to enumerate the specific fire‑code provisions that should apply to multiplex buildings. Fire representatives warned that invoking the IFC without carve‑outs could trigger requirements such as standpipes or enhanced radio‑communications systems; the tag agreed to keep IFC references but noted BFRW or public comment may prompt specific carve‑outs.
The EV parking updates (R7.4.0.1) were incorporated: for new multiplex dwellings with shared on‑site parking, a 20% minimum of shared spaces should be EV‑ready; minimum branch‑circuit capacity and infrastructure provisions were included (40‑amp branch circuits, infrastructure to allow future EVSE serving adjacent spaces, and accessible parking provisions). Tag members debated whether the 20% calculation should include interior/in‑building parking and whether to retain an 'automobile parking space' definition; the group agreed the language is sufficiently clear to proceed and public comment will be invited.
John Hall moved to replace section 105 in R7.3 with the R7.4 EV/parking text and forward the consolidated package to BFRW; Rich Geiske seconded and the motion passed by voice vote. Chair Roger Haringa asked staff to post a clean (non‑tracked) version for public review prior to the Friday BFRW meeting.
