LA Kitchen HVAC and Title 24 Compliance 2026: Ducting, Lighting, and Slab Layout Impacts

Why This Matters in December

Spring permits are already stacking up. HVAC design delays are the #1 reason LA kitchen projects stall.

HVAC Ducting in LA Kitchens

Range hoods over 400 CFM require makeup air systems.

Common challenges:

• Long duct runs in slab homes

• Limited ceiling cavities

• Noise compliance issues

Slab vs Crawlspace Homes

• Slab foundations: Sawcutting concrete adds cost and permits

• Crawlspaces: Easier duct routing, lower labor

Pasadena and Sherman Oaks homes differ drastically despite similar square footage.

Title 24 Lighting Rules

Kitchen lighting must meet:

• High-efficacy requirements

• Zoned switching

• Wattage limits

LED retrofits alone may not pass without layout changes.

Cost Ranges (Assumptions Included)

• Hood ducting: $3,500–$8,000

• Makeup air: $4,000–$7,500

• Title 24 lighting upgrade: $2,500–$6,000

Assumes single-family home, no hillside grading.

FAQ

Do all hoods need makeup air?

Only those over 400 CFM.

Does Title 24 apply to remodels?
