Summary
In Carson's RA, RS and RM residential zones, no building or structure may exceed 30 feet, measured from the average grade of the abutting curb rather than the roofline.
No building or structure shall exceed a height of thirty (30) feet as measured from the average grade of the existing or proposed curb abutting the subject lot.
Full Breakdown
Carson Municipal Code § 9126.12 caps residential structures at 30 feet, measured from the average grade of the existing or proposed curb abutting the lot, not the roof ridge or the highest point of a sloped lot. The 30-foot cap applies across the RA (Residential Agricultural), RS (Single-Family) and RM (Multiple-Family) zones under Part 2 of the city's 1977 Zoning Ordinance, Article 9, Chapter 1. That chapter remains the codified residential standard even as Carson phases in a separate New Zoning Code adopted by Ordinance No. 24-2405; confirm with Community Development which code applies to a given parcel before designing to the limit.
Violations & Fines
Exceeding the 30-foot cap without an approved permit is a Municipal Code violation; unless declared an infraction, it defaults to a misdemeanor under CMC § 1200(a): up to $1,000 and six months in jail, each day a separate offense.
