Full Breakdown
030 applies Table 2-2, "Development Standards for Single-Unit Residential Zoning Districts," across the R-A, R-1, R-1-6,000, R-1-7,200 and R-1-10,000 districts. " For lots 40 feet wide or less, R-1-6,000, R-1-7,200 and R-1-10,000 are each capped at 60 percent, while the table marks R-A and base R-1 as not applicable for that row. For lots wider than 40 feet, R-A drops to a 40 percent maximum while R-1-6,000, R-1-7,200 and R-1-10,000 remain at 60 percent; base R-1 again carries no separate coverage percentage, meaning that district's footprint is instead controlled through setbacks and floor area limit rather than a standalone coverage cap.

Owners planning an addition or rebuild must confirm their lot's coverage math against the applicable district column before submitting plans, since a corner versus interior lot and lot width each pull different figures from the same table.
Violations & Fines
A coverage violation is handled administratively under Chapter 20.68. The Director issues a written Notice of Violation under Section 20.68.040 that cites the Zoning Code section violated, sets a correction deadline, and warns that the City may bill the owner for abatement costs; owners may request a meeting with the Director to negotiate the timeline. Under Section 20.68.050, the City can also revoke or modify any permit or variance tied to the property following a public hearing with ten days' mailed notice (24 hours for limited-term permits), on top of any other remedy available under Title 1 or civil action for an illegal structure under Section 20.38.030(E).
