We design and build high-end, fully managed ADUs in Malibu for homeowners who want privacy, quality, and architectural cohesion—not cheap additions.
Building an ADU in Malibu isn’t a simple add-on—it’s a decision that impacts your property’s value, privacy, and long-term usability.
Most homeowners we work with are not just looking for “extra space.” They want something far more specific:
A private, well-designed guest residence
A space that matches the architecture of their home
A builder who can navigate Malibu’s complex permitting and coastal requirements
A process that is organized, discreet, and professionally managed from start to finish
At Kol & Co., that’s exactly what we deliver.
With over 15+ years of experience, and as a fully licensed, bonded, and insured design-build firm, we specialize in creating high-end ADUs that feel intentional, integrated, and built to last.
Malibu is one of the most desirable—and most complex—places to build in California.
Every project must account for:
This is where many projects fall apart—poor planning, delays in permitting, or designs that don’t translate well once built. Our approach is different.
We combine design, engineering, and construction under one roof, allowing us to anticipate challenges early and execute with precision.
In Malibu, an ADU should never feel like an afterthought. We design each project based on your property, your goals, and how the space will actually be used—resulting in fully realized living environments, not generic units.
Independent structures designed for privacy, comfort, and flexibility.
Ideal for:
Each unit is thoughtfully positioned to maximize privacy, flow, and architectural harmony with the main home.
Integrated additions that feel like they were always part of the home. We carefully match:
The result is a natural extension—not a visible add-on.
We turn underutilized garages into high-end, livable spaces. Common uses include:
These projects are designed to feel intentional, not improvised.
Built specifically for Malibu’s terrain. We specialize in:
This level of building requires experience—because mistakes are costly and difficult to correct.
For homeowners who want something beyond standard categories. We design spaces such as:
Wellness retreats
Executive workspaces
Multi-generational living environments
High-end rental units
Every detail is customized—because no two properties, or clients, are the same.
A well-built ADU in Malibu typically costs:
$300 to $600+ per square foot
Final cost depends on:
Site conditions (flat vs hillside)
Architectural complexity
Engineering requirements
Material and finish level
Type and size of ADU
In most cases, full ADU projects range from $300,000 to $600,000+, with custom hillside or luxury builds exceeding that depending on scope.
Permitting in Malibu is one of the most challenging aspects of building an ADU—and where many projects encounter delays. Beyond standard city approvals, projects may involve:
Even with California’s pro-ADU laws, Malibu still requires careful planning, accurate documentation, and strategic coordination.

An ADU in Malibu isn’t just another construction project—it’s an architectural decision that should enhance how your home feels, functions, and holds value over time.
At Kol & Co., we approach every project with that standard in mind: precision, clarity, and long-term thinking from day one.
If you’re considering building an ADU, the most important step isn’t design or construction—it’s understanding what’s actually possible on your property.
That’s where we come in.
We’ll give you a clear, honest assessment of:

Yes. All ADUs in Malibu require permits, and the process typically involves city approvals, building code compliance, and in some cases coastal and environmental review. The permitting process can be complex, which is why we manage it fully for our clients from start to finish.
Timelines vary depending on design, site conditions, and permitting requirements. On average, most ADU projects take several months for design and approvals, followed by construction. Malibu projects can take longer due to coastal and hillside regulations, which is why proper planning is critical.
Yes. Kol & Co. is a full design-build firm, meaning we manage everything under one roof—from feasibility and architectural design to permits and construction. This ensures better coordination, fewer delays, and higher-quality results.
