Custom gunite pools, remodels, spools and hillside builds in Malibu, with the local permit path, the local cost band, and the local ground rules published on this page before anyone asks for your number.
Malibu is the service area's coastal premium market, and the only city here where a pool permit starts in a planning department rather than a building counter. The lots run from Carbon Beach and Point Dume flats to bluff and canyon parcels in Serra Retreat and Big Rock, and nearly every one of them carries a second design authority besides the building code: the city's Local Coastal Program, written to protect the coast the lots look at. Add the geology of the Santa Monica Mountains meeting the sea, onsite wastewater systems on most parcels, and a city still rebuilding after the January 2025 Palisades Fire burned into its eastern end, and Malibu pool work is its own discipline.
This page publishes what could be verified from the city's own sources, its Local Coastal Program text and its Development Portal, and leaves out what could not. The shape of it: a planning review first, where coastal rules decide what can be built and whether a coastal permit is even required, then building plan check, then the pool permit itself. Timelines here are not quoted from other cities' experience, because Malibu's queue is its own. What can be promised is a process run in the right order, with the coastal questions answered before the expensive drawings start.
The band below is the Malibu row of the Conejo market planning ranges published on the cost guide. Every figure is labelled a planning range, not a quote; the line-item estimate after a site visit is the real number, and the calculator narrows a range from your size, spa, and site answers.
| Tier | What it describes | Planning range |
|---|---|---|
| Spool & plunge | Compact gunite pool or pool and spa combo for smaller yards, standard equipment set, flat lot, included decking band | $65,000–$95,000 |
| Standard gunite | Custom gunite pool, standard equipment set, flat lot, included decking band | $100,000–$140,000 |
| Custom with spa | Gunite pool with attached spa, upgraded finishes and features | $140,000–$185,000 |
| Hillside & luxury | Slope engineering, retaining, infinity edges, full outdoor living scope | $185,000+ |

Permit path, in the city's own order: Malibu runs projects through its Development Portal in two phases, Planning first, Building second, per the City of Malibu's portal guidance. In Planning, the project is read against the Local Coastal Program. The Malibu Local Implementation Plan, Section 13.4.1, exempts improvements to existing single-family residences, a category its text says includes structures normally associated with a residence such as swimming pools, from the requirement to obtain a Coastal Development Permit, unless the exceptions listed in that section apply. A pool built as part of larger new development instead rides inside that project's Coastal Development Permit, as the city's recent approvals show. Planning staff confirm which side of that line a given project sits on.
After Planning approval, Building Safety takes plan check, and the pool itself is permitted as a spa/pool permit through the same Development Portal, the permit type the city's Building Safety pages name. The state safety rules apply in Malibu as everywhere: §115922's two features and the §115923 enclosure, verified before final inspection.
Two Malibu realities belong in the design brief from day one. Most lots run on an onsite wastewater treatment system, and where the pool sits relative to that system is part of the review. And hillside, bluff, and canyon plan sets typically carry soils and geology reports, because the ground here is the project. Neither is a surprise to a builder who works in this city; both are surprises to one who does not.
Slope and soil: Malibu is Santa Monica Mountains geology at the shoreline: sandstone and shale slopes, ancient landslides in the record, bluff edges, and canyon drainage. Pool structures here are engineered against geology reports, not against a standard detail, and drainage is designed for storm events coming off burned or bare slopes as well as ordinary rain. Inland, Thousand Oaks §1808.7.3 is the slope setback rule local builders quote as a benchmark; in Malibu the equivalent answers come lot by lot out of the geology review and the coastal reading of the site.
Often not, on the city's own text: the Local Implementation Plan at Section 13.4.1 exempts improvements to existing single-family residences, pools named among the associated structures, from a CDP, unless that section's exceptions catch your project. A pool that is part of new construction or a larger development is handled inside that project's CDP instead. City Planning staff make the call for your parcel, which is why the process starts there.
One: submit through the city's Development Portal for Planning review, where the coastal reading happens and staff determine whether any coastal approval is required. Two: Building Safety plan check on the approved design. Three: the spa/pool permit issues, construction follows, and inspections run through the same portal. The builder partner prepares each package with you.
Inside the rebuild's approvals. Where a home is being replaced, the pool is normally part of that project's planning and coastal package rather than a standalone application, and its design, drainage, wastewater clearances, and geology, is read with the house's. The consultation starts with what stage your rebuild's approvals have reached, because that decides the pool's fastest honest path.
