Most Malibu remodels and additions that extend beyond the existing footprint, or that count as 'substantial' work, fall under California Coastal Commission jurisdiction in addition to the City of Malibu's standard building permit process. The extra layer is the Coastal Development Permit, or CDP. This guide walks through what a CDP is, when it tends to apply, what the process looks like in plain terms, and how all of it affects your remodel timeline. It is a homeowner-oriented overview — not a substitute for direct conversations with the City of Malibu planning department or the Coastal Commission.
What a Coastal Development Permit actually is
A Coastal Development Permit is a discretionary approval that the California Coastal Commission (or, in some areas, a city delegated by the Commission) issues for development in the coastal zone. In Malibu, much of the residential inventory falls inside the coastal zone — the boundary varies and is mapped by the Commission.
A CDP is layered on top of, not instead of, your standard building permit. You typically need the planning side of the CDP cleared before, or in parallel with, plan-check on the construction documents. The Coastal Commission is looking at things like view corridors, public access, environmentally sensitive habitat areas (ESHA), bluff-top setbacks, septic and water impacts, and consistency with the city's Local Coastal Program (LCP).
When a CDP tends to apply
Whether your project triggers CDP review depends on the property, the scope, and the specific overlay. The general pattern in Malibu is:
- New construction in the coastal zone almost always requires a CDP.
- Additions, especially those that increase footprint, height, or floor area, often require a CDP.
- 'Substantial' remodels — meaning work that goes beyond cosmetic and minor maintenance — often require a CDP. The line between 'substantial' and 'minor' is interpreted by the planning department.
- Work strictly inside the existing footprint, with no exterior change, sometimes stays on a standard building permit. This is the most common path for kitchen and primary-bath remodels that don't move walls outward.
- Anything in an ESHA (Environmentally Sensitive Habitat Area), in the wave run-up zone, on a bluff face, or near a public access easement gets additional scrutiny.
What the CDP process tends to look like
A CDP review is a planning process, not a plan-check process. It typically runs alongside or before construction-document plan-check. There are local Malibu-issued CDPs, Commission-issued CDPs, and waivers for certain minor scopes — which path your project takes depends on the parcel and scope.
Plan on a multi-month process for any substantive CDP. Six to eighteen months is a range homeowners commonly see in the Malibu coastal zone, depending on the parcel, scope, and whether the project goes to the Coastal Commission directly or through the City of Malibu. ESHA, bluff-top, and access cases tend to land at the higher end of that range. Confirm current processing times with the City of Malibu planning department.
Documents and information typically required
A CDP application typically draws on several documents that take time to assemble:
- Site plan and survey, often including a topographic survey
- Existing and proposed floor plans, elevations, and sections
- Biological survey (if ESHA may be present)
- Geological / geotechnical report (especially on bluff or hillside lots)
- Septic / wastewater analysis (where applicable)
- Public access and visual-impact analysis (for parcels near the coast or with visible bluff faces)
- Demonstration of consistency with the City of Malibu Local Coastal Program (LCP)
How CDP timing affects your remodel plan
If you are considering a Malibu project, build planning time into your front end. Design and CDP processing typically run six to eighteen months before construction starts. That means the homeowners who reach out twelve to eighteen months ahead of when they would like construction to begin are giving themselves the most flexibility.
Projects scoped to stay inside the existing footprint sometimes avoid CDP review entirely and can move on a more standard timeline. We help homeowners understand which path their project may fall into before design starts — but the planning department has the final word.
Next steps if you are planning a Malibu remodel
If your address is in the Malibu coastal zone and you are starting to think about a remodel, the most useful first step is a feasibility conversation that names which path your project may take. We do this as part of a first consultation — what the parcel allows, what the scope would likely trigger, and what realistic timing looks like for both paths.
Reach out for a free estimate. We are available for consultations in and around Malibu — Point Dume, Big Rock, Carbon Beach, Malibu Park, La Costa, Paradise Cove, Sunset Mesa, and adjacent areas.
