What Property Owners Need to Know About the 2025 CalGreen Code (Effective January 1, 2026)

California’s 2025 CalGreen Code introduces major changes for multifamily, hospitality, office, and mixed-use properties. The biggest updates reshape how EV charging, parking, and bike storage must be designed into new developments and major renovations.

This guide explains what’s changing and how owners can stay ahead while future-proofing their portfolios.

What the 2025 CalGreen Code Is

CalGreen is California’s baseline sustainability and infrastructure standard. It applies to all new construction and many significant alterations. The 2025 update goes into effect January 1, 2026, and directly influences permitting, electrical planning, and development costs.

Why This Matters for Property Owners

These updates add real design and electrical complexity. EV charging is no longer optional. Bike parking is no longer minimal. Office, multifamily, and hospitality properties must now be built with the infrastructure today’s drivers, guests, and tenants expect.

Owners who fail to plan early face costly rework and delays. Owners who get ahead can differentiate their assets and capture stronger long-term value.

Key Changes: Before vs After

A simple breakdown of what’s shifting under the 2025 CalGreen Code.

1. EV Charging Requirements

Before (Current Requirements)

• Many multifamily, hotel, and office projects only needed a small percentage of EV capable or EV ready spaces.

• In many cases, conduit only or partial electrical infrastructure was enough.

• Few spaces required actual Level 2 chargers.

• Electrical load planning was more flexible and lower cost.

After (2025 CalGreen Requirements)

Multifamily

• Most parking spaces (commonly 70 to 100 percent) must now include low power Level 2 receptacles.

• At least 10 to 25 percent of shared or unassigned spaces must include fully installed Level 2 chargers.

• Electrical demands increase materially, often requiring 2 to 4 times more wiring, conduit and panel capacity than previous cycles.

Hospitality

• 40 percent of all parking must include low power Level 2 receptacles.

• 25 percent must include full Level 2 chargers installed for guests.

• Hotels that previously installed only a handful of chargers now need dozens.

Office / Commercial

• Higher mandatory EV ready and EV installed requirements, often jumping from 10 percent to 30 to 50 percent depending on building size.

• Increased employee and visitor demand requires substantially more electrical load and parking allocation.

• New designs must support large scale EV readiness rather than small pilot installations.

All Property Types

• EV charging must now be designed into the building’s electrical system from the start.

• Large increases in branch circuits, panel capacity, and load management needs.

• Alterations to existing parking may trigger EV upgrades.

2. Bicycle Parking Requirements

Before

• Many properties met minimum bike parking requirements with limited storage or short-term racks.

• Requirements varied by jurisdiction and were typically low.

After

• Multifamily, hotels, and offices must now provide more secure, long-term bicycle parking.

• Ratios have increased, which affects amenity space, layout, and storage planning.

• Long-term bike parking must meet security and weather protection standards.

3. Code Interpretation and Local Adoption

Before

• Definitions and enforcement varied across jurisdictions.

• Many owners did not encounter EV or bike requirements at scale.

After

• Updated definitions clarify expectations.

• Local jurisdictions may adopt additional standards on top of CalGreen.

• More projects will be required to comply, including major renovations.

What Property Owners Should Do Now

1. Review Upcoming Developments and Renovations

The new EV requirements reshape electrical load, parking layout, and design planning.

2. Bring in Specialized Partners Early

Because EV charging is now a required building system, experienced turnkey support prevents delays, surprises, and unnecessary costs.

3. Adjust Budgets and Timelines

The expanded EV and bike requirements create meaningful new infrastructure needs. Planning now protects your ROI.

4. Use Compliance as a Competitive Advantage

EV charging and secure bike storage are now baseline expectations. Properties that deliver them attract higher value residents, guests, and tenants.

5. Coordinate with Utilities and Authorities

Electrical upgrades and jurisdictional clarifications should happen early in design.

Final Takeaway

The 2025 CalGreen Code is a major shift for California real estate. EV charging, bike parking and modern infrastructure are now core building requirements. Owners who move early can turn compliance into a long term competitive edge. As regulation continues to tighten across the U.S., the properties that stay proactive, future ready and infrastructure aligned will outperform those that wait until requirements become urgent or costly.
