HOA vs. City Rules: Pittsburg vs Walnut Creek

In Pittsburg, homeowners associations governed by the Davis-Stirling Common Interest Development Act (California Civil Code sections 4000 through 6150) may impose rules stricter than city ordinances, but cannot override state-protected activities such as solar installations, ADUs, family day care, clotheslines, electric vehicle charging, or pride and religious displays. City rules set the minimum, and CC&Rs can only go further in the same direction.

Walnut Creek has many HOAs — including the 10,000+ unit Rossmoor 55+ community — governed by the Davis-Stirling Common Interest Development Act (Civil Code §4000 et seq.). Where HOA rules and city ordinances differ, the stricter rule generally controls, but state law preempts HOAs on solar, EV charging, ADUs, and clotheslines.
