Full Breakdown

Anyone proposing an addition, new garage or accessory structure should have the Building and Safety Division confirm coverage before framing begins, since lot coverage is checked against the plans at permit issuance, not after construction.
Violations & Fines
Glendale's zoning code does not list Table 30.11-B lot-coverage overages among the reduced-penalty infractions in § 1.20.010(D), so exceeding the coverage cap falls under the general rule in § 1.20.010(A): a misdemeanor punishable by a fine of up to $1,000, up to six months in county jail, or both, with each day the violation continues counted as a separate offense. The Building and Safety Division catches most overages at plan check and will not issue a permit, or will red-tag work in progress, until the plans are revised to fit within the cap.
