Zoning, building permits and septic rules in Malibu, California

Malibu’s own rules

• Local zoningPresent (with conditions)

  Land inside Malibu city limits: the City of Malibu's own zoning ordinance (Malibu Municipal Code Title 17) administers land use and development.

  • Title 17 is the zoning ordinance; the city's eCode360 amendment list shows it amended repeatedly, including by an ordinance the list says is listed through ord. no. 535 adopted June 22, 2026 (per the eCode360 landing page).
  • Malibu also operates under a Local Coastal Program (LCP land use plan and local implementation plan are separate eCode360 titles); coastal rules may add conditions not checked here.

  “this title of the malibu municipal code shall be known as the malibu zoning ordinance.”

• Who permits septicLocal (with conditions)

  New onsite wastewater treatment systems (OWTS, septic) on land inside Malibu city limits.

  • Operating permit is issued by the City of Malibu after the system is determined to be functioning properly.
  • The amendment list on the eCode360 page marks the OWTS operating-permit provisions (ch 15.44) as '(pending coastal commission certification)'; certification status was not verified.

  “an operating permit shall be issued for the new owts when the system is determined to be functioning properly and is approved by the city of malibu.”

• Septic permitRequired

  Owner of real property served by an existing OWTS inside Malibu city limits, when the owner applies to repair, alter, modify, replace, renovate, or relocate that OWTS (and other listed circumstances on the page not fully read).

  • Application is concurrent with any required development permit, or with the environmental health approval application when no development permit is required.
  • Other circumstances listed under this section were not fully read within budget.
  • Source list marks the OWTS operating-permit amendment as pending Coastal Commission certification; not verified.

  “the owner of real property served by an existing owts shall be required to apply for and obtain an operating permit for the owts in each of the following circumstances”

  One more reviewed finding on this topic

  • Required — A development project that includes construction of a new OWTS on real property not currently served by an OWTS, inside Malibu city limits.

    “a certificate of occupancy for the development project shall not be issued until a valid operating permit is secured.”

Still unanswered

We looked and could not find an official answer yet. Silence is not permission; ask Malibu or Los Angeles County directly.

• Building permit — General building permits for construction inside Malibu city limits.
• Owner-builder exemption — Owner-builder permit exemption inside Malibu city limits.
• Building code adopted — Building code adoption for land inside Malibu city limits.
• Inspections — Building inspections inside Malibu city limits.
• Certificate of occupancy — General certificate of occupancy for new dwellings inside Malibu city limits.

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
