Thinking about a remodel, ADU, or new build in Cardiff? You have probably heard that Encinitas updated its green building rules, and it can feel confusing if you are not working with these codes every day. You want to do the right thing, keep timelines on track, and avoid surprises at plan check. This guide breaks down how California’s Title 24 energy code and CALGreen work, and how Encinitas can layer on local requirements so you can plan with confidence. Let’s dive in.
Encinitas rules in plain English
Encinitas follows California’s statewide standards and can adopt local rules that go beyond the minimum. You will see three layers at play on most projects: Title 24 energy standards, CALGreen green building requirements, and any Encinitas-specific amendments.
Title 24 energy basics
Title 24 Part 6 sets the statewide energy-efficiency baseline for insulation, windows, HVAC, lighting, and controls for both new homes and major remodels. You will comply through either a prescriptive checklist or a performance path that uses energy modeling. Some features require testing and verification, such as duct leakage tests and HERS verification. Most new single-family homes must include rooftop solar under recent code cycles; local ordinances cannot reduce that requirement.
CALGreen essentials
CALGreen, Title 24 Part 11, sets green building measures focused on water efficiency, indoor air quality, and construction waste diversion. Mandatory measures apply to most new construction and some alterations depending on scope. CALGreen also includes optional Tier 1 and Tier 2 measures that cities can choose to require.
How local rules stack
California allows cities to adopt “reach codes” that are more stringent than state minimums. Encinitas can add requirements on top of Title 24 and CALGreen, such as EV charger readiness, additional water-efficiency standards, or electrification for certain project types. The state rules are the foundation, and the city can add more, but it cannot reduce state minimums.
What to check in the Encinitas ordinance
Because local amendments are precise, your first step is to confirm what applies to your property and project type in Cardiff-by-the-Sea. City ordinances, permits, and local enforcement apply in Cardiff just like the rest of Encinitas.
Applicability and triggers
- Identify which projects are covered. New single-family homes, ADUs, large additions, and major remodels may trigger different requirements.
- Confirm size thresholds and any exemptions. Historic properties and small projects can be treated differently.
- Ask about effective dates and whether previously permitted projects are grandfathered.
EV and solar readiness
- Many California cities require EV-capable or EV-ready parking for new residential construction. Verify if Encinitas includes this and for which project types.
- State code requires rooftop solar for most new single-family homes. Check if Encinitas adds solar-ready details or other on-site renewables expectations.
Water and indoor air quality
- CALGreen mandates water-saving fixtures and construction waste diversion. Local amendments can set stricter fixture flow rates, irrigation limits, or landscape standards.
- Ventilation and low-emitting materials support indoor air quality. Some cities add enhanced ventilation or low-VOC material requirements.
Verification and enforcement
- Expect Title 24 forms, HERS testing when required, and a CALGreen checklist.
- Encinitas may require specific checklists, third-party verifications, or diversion manifests to close permits.
Fees and timelines
- Added plan-check steps or inspections can affect timing and cost. Confirm whether the updated ordinance changes submittal requirements that could extend review.
Your step-by-step planning checklist
A little preparation upfront will save time and reduce stress during plan check and inspections.
Pre-planning and permits
- Ask the city building counter which parts of the updated green ordinance apply to your scope.
- Confirm ordinance effective dates and whether your project can be grandfathered.
- Determine if you need energy modeling, HERS verification, or third-party testing.
Design and contractor selection
- Hire designers and contractors experienced with Title 24, CALGreen, and Encinitas plan review.
- Request a scope checklist that shows how your team will meet energy and green measures, including insulation values, window specs, HVAC choices, duct sealing, and water-efficient fixtures.
What to include at submittal
- Title 24 compliance documentation, such as CF1R forms or energy modeling reports.
- A CALGreen checklist and a construction waste management plan or diversion documentation.
- If applicable, EV-ready wiring diagrams, solar-ready plans, and water-efficient landscape details.
- HERS verification plans and testing reports, including duct and blower-door test results when required.
During construction and inspections
- Expect in-field checks for air sealing, duct leakage, and equipment installation.
- Keep records and manifests for waste diversion and materials per city requirements.
After completion
- Final approvals often require all energy and CALGreen compliance reports. Keep copies for your records. Buyers increasingly ask for documentation, which can support resale value and buyer confidence.
Common project scenarios
Every property is different, but these scenarios cover the most common questions we hear from Cardiff homeowners.
Building a new single-family home
- Plan for Title 24 energy compliance and the state rooftop solar requirement.
- Check if Encinitas requires EV-ready infrastructure and any local amendments on water, landscape, or indoor air quality.
- Expect HERS verification for certain features and a CALGreen checklist as part of inspections.
Adding an ADU or converting a garage
- ADUs may trigger both energy and green measures depending on size and scope.
- Confirm if the local ordinance applies to your ADU and whether EV readiness, solar-ready, or specific water-efficiency measures are required.
- Ask about any unique submittal items for ADUs to avoid delays.
Large addition or major remodel
- Additions over certain thresholds can trigger energy modeling under Title 24 and CALGreen measures.
- Even when not required, early coordination on air sealing, duct work, and window specifications can prevent change orders.
- Confirm testing requirements so your contractor schedules HERS and inspections at the right milestones.
Costs, timelines, and resale
Some green building measures increase upfront costs, such as higher-efficiency HVAC or EV infrastructure. Others reduce operating costs through lower utility bills. Plan-check timelines can extend when extra documentation or verification is required. The exact impact depends on your scope. On the resale side, documented energy performance, rooftop solar, and modern systems can be attractive to today’s buyers. Keeping organized records of compliance can support stronger buyer confidence.
Incentives to explore
Programs change often, so confirm current offerings before you finalize your budget. Start with:
- Utility incentives. SDG&E and regional programs may offer rebates for heat pumps, efficient HVAC, heat pump water heaters, or EV chargers.
- State and federal incentives. Tax credits, rebates, and financing programs for efficiency, electrification, and solar evolve over time.
- County or regional programs. San Diego County and partner agencies may have added support for water efficiency or decarbonization.
Your contractor or energy consultant can help you compile current options for your specific project.

- Title 24 covers energy efficiency, while CALGreen addresses broader green measures like water efficiency, indoor air quality, and construction waste diversion.
Do I need rooftop solar for a new home in Cardiff?
- Most new single-family homes in California must include rooftop solar under recent Title 24 code cycles. Local rules cannot reduce this statewide requirement.
Will I need a HERS rater for my remodel?
- Some measures, such as duct testing and certain performance-path items, require HERS verification. Your designer or contractor should confirm what applies to your scope.
Do green building measures add a lot of cost or delay?
- Some features can add upfront cost, while others lower operating bills. Extra documentation can extend plan-check timelines. Impacts vary by project size and complexity.
Do these rules affect ADUs and garage conversions in Encinitas?
- Many ADUs trigger energy and green measures depending on size and scope. Check the ordinance thresholds and ask the city which requirements apply.
Can older projects be grandfathered under previous rules?
- Projects permitted before an ordinance’s effective date are sometimes grandfathered. Confirm status with the city before making design or budget decisions.
