The short answer

Condos and townhomes

An HOA can require approval and set reasonable rules but can't ban solar or require a membership vote for a system on your own roof or assigned carport (§714.1). On a shared roof you must insure, maintain and later remove the system and restore the roof, and disclose it to buyers. See HOA solar rights.

Apartment buildings

Virtual net metering let a building owner split one system's credits among tenant accounts. New applicants since Feb 15, 2024 take the Virtual Net Billing Tariff instead, unless they qualify for the affordable-housing (SOMAH or MASH) versions (CPUC). Deed-restricted affordable buildings can get SOMAH incentives (SOMAH).

LADWP buildings

LADWP has been piloting virtual net metering for multifamily buildings; ask LADWP about current terms.
