California Window Tint Laws: What You Need to Know for Homes, Cars, and Businesses

California has some of the clearest window tinting regulations for vehicles in the country, but many people don't realize that homes and commercial buildings have their own set of considerations — primarily around HOA restrictions, building codes, and historic district guidelines rather than state law. This guide covers what you need to know before tinting any glass in California.

Automotive Window Tint Laws in California

California Vehicle Code § 26708 governs aftermarket window film on passenger vehicles. Key requirements include:

• Windshield: Tint film is allowed only on the top 4 inches.
• Front side windows (driver and passenger): Qualifying clear/colorless film must have an 88% minimum VLT. The combined VLT of the window plus film must meet the federal 70% minimum.
• Rear side windows: No VLT restriction for passenger vehicles. Any darkness is permitted.
• Rear window: No VLT restriction, but the vehicle must have outside rearview mirrors on both sides if the rear window is tinted.

Per the statute, front-side window installations must be accompanied by an installer certificate. We provide all necessary documentation for compliance. Link to official statute: CVC 26708.

Residential Window Tinting: HOA and Local Considerations

California state law does not restrict residential window tinting. However:

• HOA guidelines: Many Homeowners Associations in Los Angeles — particularly in Bel Air, Palos Verdes, Beverly Hills flats, and gated communities — have exterior appearance guidelines that apply to window modifications.
• Historic district guidelines: Some Pasadena, West Adams, and Silver Lake properties in designated historic districts may require approval for exterior modifications including window film.
