Local zoningPresent (with conditions)
Land inside Moorpark city limits: Moorpark city's own Title 17 Zoning in its adopted code of ordinances
Presence is established from the adopted code's table of contents, which lists Title 17 Zoning (§ 17.04.010 to § 17.74.070). The zoning chapter text itself was not opened, so district standards and use tables are not verified here.
Ordinance text on eCode360 at https://ecode360.com/MO4972 is the source; third-party mirrors were not used as evidence.

Ventura County's Environmental Health Division states it is the authority with jurisdiction for OWTS in unincorporated Ventura County only; the page directs owners with systems inside city limits to the city building department.

Unanswered questions are usually a sign that Moorpark publishes no rule on the point, not that none exists. Ventura County’s page lists the county offices to call.
