A client plans to convert a former office suite into a 180-seat restaurant. The shell has a current certificate of occupancy, and the client describes the project as a finish-only renovation. What must occur before the layout is advanced?
Correct answer: B - Reclassify the proposed use and repeat the applicable code analysis
A Group A-2 restaurant dining area contains 1,650 net sq ft of tables-and-chairs seating. Use an occupant-load factor of 15 net sq ft per person; no single-exit exception applies. Which conclusion belongs on the life-safety plan?
Correct answer: C - 110 occupants; provide at least two doors swinging in the direction of egress travel; latched doors require panic hardware
A fully sprinklered Group B floor has an exit-access travel distance of 285 feet. All other egress conditions comply, but a reviewer applies a universal 250-foot maximum. What is the appropriate code response?
Correct answer: D - Retain the path because 285 feet is within the 300-foot sprinklered limit
Interviews for a university tutoring center identify unpredictable noise, glare, and visual clutter as the principal barriers for neurodiverse students. Which pre-design response turns those findings into defensible project criteria?
Correct answer: C - Set acoustic, glare, zoning, and retreat criteria, then validate them with representative users
Two counseling rooms share a partition that stops at the ceiling grid and contains back-to-back electrical outlets. The ceiling tile has an NRC of 0.90, yet speech remains intelligible next door. Which change addresses the governing deficiency?
Correct answer: A - Provide a continuous sealed sound barrier and close the outlet and door leakage paths

An ASTM E84 report for a proposed wall finish lists a flame-spread index of 68 and a smoke-developed index of 410. The project requires an IBC Class B finish or better. How should the finish be classified?
Correct answer: B - Class B because both reported indices are within its limits
Before approving a guest-room design for repetition across a 180-room hotel, the owner wants evidence that luggage movement, accessible approach, lighting, millwork, outlets, and housekeeping access work together. Which validation method provides the strongest evidence?
Correct answer: A - Build a full-size benchmark room and test it against approved performance criteria
