Summary
Multifamily residential development processed under Santa Ana's Planned Community Development (PCD) provisions is capped at fifty percent lot coverage under Section 41-575. Buildings, driveways, parking areas and covered patios together may take up no more than half the site; the remaining half must stay open as landscaping, recreation space or walkways, keeping density in check.
The following maximum lot coverage shall be applied to multiple-family residential land use categories designated on the adopted general plan of development: Not more than fifty (50) per cent of the total lot area shall be devoted to main and accessory building area, driveways, open or enclosed parking areas and covered patios. The remaining fifty (50) per cent of the total lot area shall be devoted to landscaping; lawn area; noncommercial outdoor recreational facilities incidental to the residential development, such as private swimming pools, putting greens and tennis courts; walkways, uncovered patio areas; fences and necessary fire-fighting equipment and installations... For purposes of the calculations required by this section, private streets shall not be included in total lot or building site area.

Full Breakdown
Section 41-575, part of Division 22 (PCD. Planned Community Development) of the zoning chapter, sets the ceiling on how much of a multifamily site in Santa Ana can be built over. " The section also bars using the required open space for "commercial agricultural pursuits or any other activity in conflict with the stated purpose of this district," and excludes private streets from the lot-area calculation. Because the standard sits in the PCD division, it governs multifamily projects processed through a planned-development entitlement rather than every apartment parcel citywide; projects should confirm with the Planning and Building Agency whether their site's general-plan designation and entitlement route make Section 41-575 the controlling coverage limit before assuming the 50 percent figure applies.
Violations & Fines
Building beyond the fifty percent cap without an approved plan amendment is enforced as a Municipal Code violation under Section 1-8: a misdemeanor carrying up to a $1,000 fine, up to six months in custody, or both, with the option for the city attorney to charge it as an infraction instead. Each day the excess coverage remains counts as a separate offense, and the city may pursue an administrative citation as an alternative to criminal prosecution.
