Understanding the Green Building Code Los Angeles
If you’re developing property in Los Angeles, you’ve likely come across the term “Green Building Code.” But what exactly does it mean? And how does it affect your timeline, your budget, and your overall permitting process?
This guide breaks it down—step by step. Whether you’re building a new residential complex, commercial building, or doing a major remodel, you’ll need to comply with LA’s green standards.
Let’s explore what this code requires, why it matters, and how you can stay ahead with the right strategy.
LA Green Building Compliance: Step-by-Step
- Feasibility Review – Identify triggers, required tiers
- Design Phase – Integrate energy, water, and waste features
- Submit Green Checklists – With permit applications
- During Construction – Track waste, verify low-VOC, install solar/EV
- Final Inspection – Submit waste logs, receive approval
What Is the Green Building Code in Los Angeles?
Los Angeles follows the California Green Building Standards Code, also known as CALGreen, but it also has its own local amendments that add extra environmental protections.
The code applies to:
New construction
Major alterations and additions
Commercial tenant improvements
Multi-family and mixed-use developments
In short, if you’re touching core systems like HVAC, plumbing, electrical, or structure—you’re likely required to follow green building standards.
LA’s goal? Reduce the city’s carbon footprint, promote healthier buildings, and ensure long-term environmental resilience.
Why This Code Matters for Developers and Property Owners
You may be wondering: Is this just another bureaucratic hoop to jump through?
Not quite. The Green Building Code in LA actually helps your bottom line—if you plan for it early.
Here’s how:
Faster approvals: Projects with full green code compliance avoid delays during plan check and inspections.
Lower operational costs: Energy-efficient and water-saving features lead to lower utility bills.
Increased building value: Green buildings are more attractive to buyers and tenants.
Public incentives: You may qualify for DWP rebates, tax credits, or streamlined approvals under SB 35 and AB 2011.
Code alignment: Many zoning incentives (like TOC or density bonuses) require you to meet green building thresholds.
Pro tip: Developers who align their entitlement strategy with green code early save time and money throughout the project lifecycle.
What Are the Main Areas Covered by the LA Green Building Code?
Let’s break down the key sections of the code that affect your design, construction, and inspection phases:
1. Site Development Requirements
This section focuses on the environmental conditions of your project site:
Stormwater drainage and permeable paving are required in many zones.
Construction site runoff control and erosion protection must be planned and documented.
You may also need native/drought-tolerant landscaping and high-efficiency irrigation.
These rules aim to reduce flooding, protect groundwater, and cut urban heat.
2. Energy Efficiency Standards
Los Angeles enforces Title 24 Part 6 and Part 11 energy codes. These rules affect:
Insulation, window glazing, and building envelope performance
HVAC system efficiency and controls
Solar photovoltaic systems (required for most new low-rise homes)
Energy modeling to show code compliance
For commercial and mixed-use projects, expect to include automated lighting controls, energy metering, and sometimes renewable energy offsets.
Don’t forget: LA’s own energy code supplements CALGreen, meaning you may face stricter thresholds depending on your building type.
3. Water Efficiency and Conservation
Water is scarce in Southern California, and the city prioritizes its efficient use. Key green code requirements include:
Low-flow toilets, faucets, and showerheads in all new and renovated buildings
Separate submeters for landscaping in buildings over a certain square footage
High-efficiency irrigation systems with smart, weather-responsive controls
Water budgets based on landscape area and plant type
This section often trips up developers who overlook irrigation plans or underestimate how much documentation is needed.
4. Indoor Environmental Quality (IEQ)
Healthy indoor spaces are part of LA’s sustainability goals. IEQ standards cover:
Low-VOC materials: paints, sealants, adhesives, flooring, etc.
Natural daylight in key spaces (especially in residential buildings)
Proper ventilation, including exhaust fans in bathrooms and kitchens
Air filtration systems in high-density buildings
IEQ rules also include moisture control (important for foundation work) and noise control for multi-family developments.
5. Construction Waste Management
LA requires at least 65% of construction and demolition debris to be diverted from landfills.
To comply, you must:
Create a construction waste management plan
Keep accurate waste hauling receipts
Submit diversion documentation at final inspection
If you’re doing a large project (10,000 sq ft+), LA Sanitation may request additional reports and waste tracking sheets.
Residential vs. Commercial: What’s the Difference?
Here’s a handy comparison:
| Category | Residential Projects | Commercial Projects |
|---|---|---|
| Solar Requirement | Required for most new low-rise buildings | Encouraged; varies by use type and zoning |
| EV Charging | 1 Level 2 EV-ready per dwelling unit | Depends on number of parking spaces |
| Indoor Air Quality | Natural ventilation or mechanical system | Must meet ASHRAE 62.1/62.2 standards |
| Water Efficiency | Low-flow fixtures and smart irrigation | Includes metering and potential greywater use |
| Construction Waste | 65% minimum diversion | 65% minimum; stricter documentation required |
This chart is especially helpful during early design meetings with your architect and MEP teams.
What Are Tier 1 and Tier 2 Requirements?
CALGreen includes two voluntary performance tiers: Tier 1 and Tier 2.
In Los Angeles, these tiers are sometimes required as conditions of approval or zoning benefits (e.g., affordable housing bonuses).
Tier 1: Adds more water and energy-saving features; requires enhanced documentation.
Tier 2: Even more aggressive thresholds (LEED Gold-level performance).
You may be required to meet Tier 1 or Tier 2 if:
You’re applying for certain density bonuses
You’re in a Transit Oriented Communities (TOC) zone
Your building exceeds certain square footage or energy budgets

Here are the most common pitfalls we’ve seen—and how to prevent them:
1. Submitting the Wrong Version of CALGreen
CALGreen updates every few years.
Each version has slightly different forms and thresholds.
Always confirm which version applies to your permit intake date.
2. Forgetting to Integrate Green Features into the Design Early
Waiting until late-phase MEP drawings to address EV chargers or solar readiness can cause redesigns.
Landscape plans should reflect irrigation controls, drainage, and non-invasive species from the start.
3. Not Planning for Waste Diversion
You need a waste management plan before demolition or grading begins.
Incomplete or missing hauler receipts = no final inspection approval.
4. Underestimating Local Amendments
LA’s code may ask for stricter indoor air quality controls or additional stormwater measures, especially in hillside or coastal zones.
CALGreen alone isn’t enough—LA adds extra layers of rules.
