Salon and Barbershop Title 24 Requirements

A 1,200 square foot salon, worked through

• Outdoor air: the table density of 17 people per 1,000 square feet gives 20.4 people at 15 cfm, or 306 cfm. Equation 120.1-F takes the larger of that and the area term, 0.4 times 1,200, so 480 cfm governs.
• Exhaust: 0.60 cfm per square foot is 720 cfm for a beauty or nail salon, and 0.50 is 600 cfm for a barbershop.
• Lighting: the barber, beauty salon and spa category allows 0.70 watts per square foot, 840 watts here.

Where nail salons sit

There is no separate nail row. Beauty and nail salons share one row in Table 120.1-A and one in Table 120.1-B, both Class 2 air. A treatment room that matches neither takes the class of the most similar listed space under Section 120.1(g)7.

No CO2 sensors

Exception 2 to Section 120.1(d)3 bars demand control ventilation in barbershops, beauty salons and nail salons. The 17 per 1,000 default sits below the 25 trigger anyway, but the bar holds even if the egress load factor is higher.

What a salon fit-out actually triggers

Part 6 attaches these rates to ventilation equipment that is new or altered (Section 141.0(b)2). If moving into a former shop changes the occupancy classification, Section 141.0(b) applies to the salon occupancy rather than the shop (Note 1 to Section 141.0). The lighting category adds 0.30 watts per square foot for detailed task work or 0.25 for decorative and display lighting, but only if the plans show the task areas, the task takes at least two hours a day, and the luminaires are separate from general lighting. File NRCC-MCH-E for the air system and NRCC-LTI-E for the lights.
