California Energy Commission (CEC) Energy Specialists Amie Brusseau walks us through a presentation of what components of the 2019 energy code apply to ADUs, from new construction to alterations and additions.
For specific technical question, reach out to:
Relevant rules from the California HCD for ADUs and JADUs including all zoning districts that allow single-family and multifamily uses, limited exemptions or reductions in impact fees, and reduced parking requirements.
Website that provides Building Energy Efficiency Standards (Energy Code) educational assistance. Resources include fact sheets, energy videos and presentations organized by topic (e.g. water heating, solar, lighting, building envelope and HVAC).
A research report with findings that a reduced home size and/or addition of an ADU is an effective strategy for reducing both energy consumption and material waste, and provides flexibility and adaptability for different family configurations over time.
A practical homeowner and developer guide with efficient electric alternatives to replace existing gas appliances. Helpful inspiration also for all-electric, new construction ADUs. Sections include a cost benefit analysis, case studies on lessons learned from retrofitted homes, and an extensive product guide.
ADU Builders, Architects, and Designers in California and nationally – Volunteer-managed list aggregating self identified companies that offer ADU services.
ADU Specialists – Accredited professionals that have completed training to help homeowners with site eligibility, development process and cost, and return on investment for ADUs.
