Santa Monica Design-Build Remodeling Contractor

Remodeling a home in Santa Monica often means working with an existing property that has character, value, and years of previous construction behind the walls. From older Craftsman and Spanish-style homes to Mid-Century properties and larger residences North of Montana, the goal is often not simply to make a home look newer—it is to make it work better without losing what makes the property special.

Kol & Co. provides full-service home remodeling in Santa Monica, including complete renovations, kitchen and bathroom remodeling, structural changes, home additions, ADUs, and custom construction.

As a licensed, insured, and bonded design-build contractor with more than 15 years of experience, we can coordinate the project from the early planning stages through design, engineering, permits, construction, inspections, and final completion.

How Much Does Home Remodeling Cost in Santa Monica?

The cost depends much more on the scope than the home’s square footage alone.

As a starting point, Kol & Co. projects typically fall around:

  • Bathroom remodeling: $25,000–$40,000+
  • Kitchen remodeling: $40,000–$70,000+
  • Full home remodeling: $200,000–$500,000+
  • ADU construction: $200,000–$500,000+
  • Custom homes/new construction: approximately $400–$600+ per sq. ft.

Projects involving major structural work, custom cabinetry, premium materials, whole-house electrical or plumbing upgrades, additions, or complex site conditions can cost more.

The best way to get an accurate number is to first define the scope, evaluate the existing property, and identify any structural, permitting, or system upgrades that may affect the project.

How Long Does a Home Remodel Take?

The timeline for a home remodel in Santa Monica depends on the size of the project, structural work, design complexity, permit requirements, and material selections. As a general guide:

Bathroom Remodel: 3–5 weeks
Kitchen Remodel: 6–10 weeks
Full Home Remodel: 4–8+ months
ADU: Approximately 12 months, including plans and permits
Custom Home: Approximately 18+ months, including planning and permits

Larger renovations involving structural changes, additions, custom materials, extensive plumbing or electrical upgrades, or more complex City review may take longer.

For major Santa Monica renovations, we recommend starting the design, engineering, and permitting process early, since these steps happen before construction can begin.

Do I Need a Permit for a Home Remodel in Santa Monica?

It depends on the work. Structural changes, wall removal, plumbing, electrical, HVAC, additions, and ADUs generally require applicable permits and inspections.

Santa Monica uses a paperless Electronic Plan Review system, with certain qualifying residential projects eligible for a streamlined permit process.

Kol & Co. handles the plans, engineering, permits, construction, and inspections required for your remodel.

Frequently Asked Questions

How much does it cost to remodel a house in Santa Monica?

A kitchen remodel may commonly begin around $40,000–$70,000+, bathrooms around $25,000–$40,000+, and significant whole-home renovations around $200,000–$500,000+. High-end finishes, structural changes, additions, custom cabinetry, extensive building-system upgrades, and larger homes can push costs higher.

Construction for a substantial whole-home renovation commonly takes approximately 4–8 months or longer, depending on the scope. Design, engineering, material procurement, and Santa Monica permitting should be considered separately when planning the overall project timeline.

Not every cosmetic improvement requires the same permitting process, but structural, plumbing, electrical, mechanical, addition, and other regulated work may require permits and inspections. The City determines the appropriate review process based on the project’s scope.

Yes. Santa Monica’s building permit process is currently paperless, and permit applications and project documents are submitted through its Electronic Plan Review system.

Often, yes. Whether a wall can be removed and what is required to replace it depends on whether it is structural and how loads are transferred through the home. Structural modifications may require engineering, calculations, permits, beams, posts, foundation work, or other reinforcement.

Yes. When the project requires architectural plans, structural calculations, or engineering, we handle those components as part of the overall design-build process.

Yes. We handle applicable permit preparation and the plan-review process for the project rather than leaving the homeowner to navigate each stage independently.

For a major renovation, addition, or ADU, it’s better to begin the conversation months before you want construction to start. Design decisions, engineering, permits, material selections, and procurement can all affect when construction can realistically begin.
