Title 24 Solar Requirements for Multifamily Construction
Every new multifamily building needs PV. Buildings of four or more stories need a battery too. The sizing depends on floor area, units, climate zone, and the roof.

Title 24 Solar Requirements for Commercial Buildings
Since 2023, most new commercial buildings in California must install solar and a battery. The 2025 code expanded the list and raised several capacity factors.
When Should Solar Be Designed Into a New Construction Project?
Schematic design. Every phase after that narrows the options and raises the cost of the same decisions.
Solar and the Certificate of Occupancy
The building's final inspection depends on the Energy Code scope being complete and documented. If solar is the last trade on site, solar is the delay.
Common Solar Mistakes in New Construction
Twelve mistakes we see on California projects, why they happen, and what the fix looks like on paper.
Solar and Battery Storage Requirements in California New Construction
Most new nonresidential buildings and all high-rise multifamily buildings that require PV also require a battery. Here is how the requirement works.
Commercial Solar Permitting in California New Construction
Solar on a new building is permitted through the building permit, a coordinated deferred submittal, or both. The path determines the timeline.
Utility Interconnection for New Construction Solar
The utility runs on its own calendar. The application is the only lever, and it belongs in construction documents.
Market and Program Analysis
From our team.
Why Going Beyond the Title 24 Minimum Pays Off in New Construction
The 2025 Energy Code tells you the smallest solar and battery system you can build. The engineering, permits, and interconnection are already paid for, so the right-sized system usually costs only the extra hardware.
LADWP Feed-in Tariff Rates in 2026: What Your Roof Can Earn
Current LADWP Feed-in Tariff base prices: 14.5 cents/kWh for 30 to 500 kW solar, 14.0 cents to 3 MW, 13.5 cents above. Contract terms, remaining program capacity, and what LA property owners can earn.
Rising Rates, Shrinking Windows: Why Timing Matters for Southern California Solar
Southern California electricity rates keep climbing while federal solar incentive deadlines are now law. The numbers behind acting on commercial solar in 2026.
Recent Fires in Los Angeles: A Call for Resilience
The January 2025 Los Angeles fires showed how fragile the grid can be. Solar plus battery storage is a practical path to community and business resilience.
