Summary
In Norwalk's R-1 single-family zone, homes are capped at two stories or 30 feet, whichever is less. Top plate height is limited to 14 feet on the first story and 24 feet on the second, keeping bulk in check under Municipal Code Section 17.05.020.
No primary building or structure in an R-1 zone shall exceed two stories or 30 feet in height, whichever is the lesser, except that non-dwelling structures which require greater height for functional purposes, such as structures for the housing of tanks, ventilating fans, church spires or similar features may exceed such height, as provided by Section 17.03.230. The maximum allowable top plate height shall be 14 feet for the first story and 24 feet for the second story.

Full Breakdown
020(A) caps every primary building or structure in an R-1 zone at two stories or 30 feet in height, whichever limit is more restrictive. 230, the city's separate standard governing penthouses and roof structures. Subsection (B) adds a second, more granular ceiling that applies inside the overall 30-foot envelope: the maximum top plate height is 14 feet for the first story and 24 feet for the second story, which controls how tall each individual floor's wall plate can rise before the roof framing begins. Together the two subsections mean a builder cannot simply max out the second-story plate height and still claim compliance if the overall roofline pushes past 30 feet, and vice versa.
Height review happens through the city's Community Development Department as part of building permit plan check for new single-family construction, additions, and second-story remodels in the R-1 zone. Because the rule sits in Title 17 (Zoning), any request to exceed it beyond the penthouse/roof-structure carve-out requires a variance rather than a routine plan-check sign-off. 2.
Violations & Fines
Building without required height compliance blocks issuance of a certificate of occupancy and can trigger a stop-work order from the Building Official under the city's building code enforcement provisions. Non-conforming height built without a variance or the Section 17.03.230 exception must be corrected or brought before the Planning Commission for relief; uncorrected violations carry the standard municipal code misdemeanor/infraction penalties applicable citywide for zoning violations.
