2026 Title 24 Update: What You Need to Know

The 2025 Building Energy Efficiency Standards (Title 24, Part 6) officially took effect on January 1, 2026. All building permit applications submitted on or after this date must comply with the new requirements. Here's what you need to know.

Key Changes in the 2026 Standards

1. Expanded Heat Pump Requirements

The new standards significantly expand heat pump requirements for both space heating and water heating. Single-family homes and multifamily buildings must now meet stricter efficiency requirements for HVAC systems, with electric heat pumps being the preferred compliance path.

2. Enhanced Battery Storage Provisions

Battery storage systems are now more integrated into the compliance calculations. The standards provide credit for battery storage that can shift solar energy use to evening hours, supporting grid reliability and reducing peak demand.

3. Strengthened Indoor Air Quality Standards

New ventilation requirements focus on improving indoor air quality while maintaining energy efficiency. This includes enhanced filtration requirements and ventilation controls that respond to occupancy and air quality conditions.

4. Updated Envelope Requirements

Insulation and fenestration requirements have been updated to reflect advances in building technology. Climate zone-specific requirements ensure that building envelopes perform optimally for local conditions.

What This Means for Your Projects

Compliance Software Updates

All approved compliance software, including CertifiedT24, has been updated to reflect the new standards. Make sure you're using the latest version to ensure your reports meet 2026 requirements.
