FAQs

Under California’s 2022 Building Energy Efficiency Standards (Title 24), solar systems are generally required on all new low-rise multifamily housing structures. Additionally, integrating solar during design is more cost-effective than retrofitting.

Solar can reduce operating expenses, improve net operating income, and increase property value. Solar upgrades also make assets more attractive to tenants and long-term investors.

Solar systems can add weight to a structure’s roof, so multifamily buildings must be structurally designed to support it. Early coordination helps avoid costly future redesigns or retrofits.

Many multifamily developers and owners can qualify for the ITC. Eligibility depends on ownership and financing structure, so it’s important to contact a knowledgeable installer before design and budgeting.

When roofing and solar scopes are coordinated and manufacturer-approved mounting methods are used, solar does not have to affect roofing warranties. Again, it’s important to verify your unique situation with a qualified installer.

With early planning, a solar installation’s effect on your building timeline should be minimal. Late-stage design changes may cause significant delays or construction rework.
