Full Breakdown
The city's site development standards set building height at thirty-five feet maximum in the R1 single-family district (LFMC § 9.44.080(B)), and the same 35-foot cap appears verbatim in the RS, R2, and R4 residential district chapters' own site development standards sections. Each of those sections notes the limit applies 'except per Section 9.144.020,' meaning Lake Forest, California (Orange County) allows exceptions only through that separate, more general development-standards section rather than through the district chapter itself; the R1 chapter doesn't restate what those exceptions are.
Violations & Fines
Exceeding the 35-foot cap without qualifying under Section 9.144.020 is a zoning violation, prosecutable as an infraction (up to $500) or a misdemeanor for repeat offenses under LFMC § 1.01.190.
