Escondido, CA Landscaping Rules: Native Plants (2026)

Escondido Municipal Code Section 33-1339, 'Standards for Landscaping,' sets the design-level rules that steer projects toward native plant materials. Under subsection (a)(1), 'a high percentage of water conserving plant materials shall be utilized in all designs,' and 'the use of turf is therefore discouraged,' with a higher percentage allowed only where turf is essential, such as school or park athletic fields reviewed by the city. Subsection (a)(3) directs that 'new landscaping should use water conserving plant materials that are native to the San Diego region or are adapted to a hot dry summer/cool winter climate,' while 'non-native or adapted varieties that require large amounts of irrigation to survive the hot dry summer season are to be avoided.'

The native-plant mandate is strongest on graded slopes. Subsection (g), 'Revegetation standards,' requires that revegetation of 'graded slopes and other disturbed areas adjacent to areas of native vegetation... provide visual and biological compatibility with the adjacent native plant materials,' referencing the grading article, Article 55. Subsection (g)(1) is a flat prohibition: 'Invasive, non-native plant materials are prohibited in revegetation areas and shall be removed.' Subsection (g)(4) further requires that plantings 'consist of annuals, perennials, groundcovers, shrubs, and trees compatible with adjacent native vegetation, capable of surviving without permanent irrigation,' meaning revegetation plant palettes must be able to establish without a permanent sprinkler system once mature. Subsection (g)(2) adds that permanent irrigation should be avoided where it is contiguous to existing native vegetation, with the director deciding case-by-case how far irrigation equipment must be set back from natural vegetation. Subsection (h) allows only temporary above-ground irrigation, capped at two years unless the director approves otherwise, to establish these native plantings before the system is removed.
