Residential remodeling involves complex structural, mechanical, and aesthetic modifications that require precise coordination between design and construction teams.
Katz Design & Builders manages the entire lifecycle of residential renovations in Los Angeles and Orange County, ensuring your project meets current building codes and strict timelines.
We handle every phase from the initial architectural layout through municipal permitting to the final installation of finishes.
The Design-Build Advantage in Renovations
Traditional remodeling often separates the architect from the general contractor, leading to communication gaps and budget overruns. We operate as a unified design-build firm.
This means a single team is responsible for both the architectural vision and the construction reality.
Our approach ensures that the designs we propose are structurally sound and financially feasible before demolition begins.
By integrating these disciplines, we streamline the schedule and provide accurate cost estimations early in the process.
Clients can review our home design and build portfolio to understand how this integrated workflow translates into completed projects.

Core Remodeling Services and Scope
A comprehensive home remodel often requires stripping a property down to its studs (“gut renovation”) to address underlying issues before applying new finishes.
We categorize our services based on structural and functional requirements.
Structural Modifications and Open Floor Plans
Modernizing older homes frequently involves removing load-bearing walls to create open floor plans. This process requires structural engineering to calculate the necessary beam spans and support posts.
We execute these structural alterations safely, ensuring the integrity of the roof and second story is maintained throughout the renovation.
Kitchen and Utility Modernization
The kitchen serves as the operational center of the residence.
A proper remodel goes beyond cabinet replacement; it involves upgrading electrical circuits to support modern appliances and reconfiguring plumbing lines for improved workflow.
Our team delivers high-performance kitchen remodeling services that adhere to the “kitchen work triangle” principles and current electrical codes.
Bathroom Overhauls and Wet Areas
Bathrooms require rigorous water management strategies. We strip existing wet areas to the framing to install new moisture barriers and cement boards.
Our bathroom remodeling division ensures that all waterproofing meets industry standards to prevent future mold or structural rot.
Exterior and Outdoor Living
Extending the living space to the outdoors is a key component of California real estate value. This includes hardscaping, decks, and pool refurbishment. We integrate these elements into the overall site plan.
Furthermore, for projects involving significant landscape rehabilitation, we ensure compliance with California’s Model Water Efficient Landscape Ordinance (MWELO), implementing smart irrigation systems and drought-tolerant planting plans to pass city/county reviews.
Property owners interested in upgrading their aquatic features can consult our pool remodeling page for details on resurfacing and equipment modernization.
Handling Legacy Properties (Pre-1978 Homes)
Older homes in Los Angeles often contain hazardous materials such as lead-based paint or asbestos in acoustic ceilings and ductwork.
Disturbing these materials without proper abatement protocols creates a severe health risk and liability. Our team coordinates certified testing and containment during demolition.
Additionally, we assess older structures for seismic retrofitting requirements, bolting the framing to the foundation to meet current earthquake safety standards.
Navigating Permits and Regulations
Construction in California is governed by the California Building Standards Code (Title 24) and local municipal ordinances.
A significant portion of our project management time is dedicated to securing the necessary permits and scheduling city inspections.
Title 24 Energy Compliance
Major renovations often trigger requirements for energy efficiency upgrades. This may include installing LED lighting, high-efficiency HVAC systems, and improved insulation.
The California Energy Commission outlines these standards which are mandatory for permit approval.
Municipal Zoning and Safety
Specific cities have unique requirements regarding setbacks, height limits, and historical preservation.
We interface directly with the Los Angeles Department of Building and Safety (LADBS) or the relevant local agency to clear plan checks.
Attempting to remodel without permits exposes the homeowner to code enforcement actions and potential difficulties when selling the property in the future.
Expanding Square Footage
Many remodeling projects aim to increase the livable area of the property. This can be achieved through room additions or the construction of secondary units.
Room Additions and Expansions
Adding a master suite or expanding a living room changes the footprint of the house. This requires foundation work and roofing integration.
We ensure that new additions blend seamlessly with the existing architecture rather than looking like an afterthought.
Accessory Dwelling Units (ADUs)
For homeowners seeking independent living quarters or rental income, we construct detached or attached units.
Our dedicated ADU contractor team manages these projects, which have their own set of state-mandated streamlining laws.
Garage Conversions
Repurposing a garage is an efficient way to gain habitable space without altering the building footprint. However, this requires bringing the structure up to residential standards, including moisture control and insulation.
We execute these garage conversion projects to provide fully permitted living areas.
Project Costs and Budgeting
Renovation costs vary significantly based on the scope of the project and the condition of the existing structure.
We provide a detailed schedule of values before contract signing so you understand exactly where capital is being allocated.
Renovation Cost Drivers
| Cost Factor | Description and Impact |
| Demolition & Site Prep | Removal of hazardous materials (like asbestos or lead) and disposal fees. Extensive demolition increases labor hours. |
| Structural Changes | Moving load-bearing walls requires engineering, steel beams, and new footings, which are significant budget items. |
| System Upgrades | Replacing galvanized plumbing with copper/PEX and upgrading electrical panels to 200 Amps. |
| Finishes & Fixtures | The selection of stone, tile, cabinetry, and appliances causes the highest variance in the final price per square foot. |
Financial Strategy Note: We strongly advise clients to set aside a contingency fund of 10-15% above the estimated construction budget.
Renovating existing structures involves “opening up” walls, which often reveals concealed conditions (such as dry rot or outdated wiring) that must be addressed immediately to pass inspection.
The Construction Workflow
A disciplined process is essential for minimizing disruption and maintaining the schedule.
- Consultation and Feasibility: We assess the property and discuss the scope to determine preliminary viability.
- Architectural Design: Creating floor plans and elevations that align with the budget.
- Engineering and Permitting: Submitting technical drawings to the city for approval.
- Rough Construction: Demolition, framing, and installation of MEP (Mechanical, Electrical, Plumbing) systems.
- Finish Construction: Drywall, flooring, cabinetry, painting, and fixture installation.
- Final Inspection: Walkthrough with the city inspector to close the permits.

Selecting a General Contractor
The contractor is your partner in risk management. It is imperative to hire a licensed professional who carries liability and workers’ compensation insurance.
Katz Design & Builders holds a Class B General Building Contractor license, authorizing us to manage all trades and structural work.
Consumer Protection Alert: Be wary of contractors asking for large upfront deposits.
Under California law, a contractor cannot legally ask for a down payment of more than 10% of the total contract price or $1,000, whichever is less.
We strictly adhere to this regulation, structuring our payments based on completed progress milestones.
Homeowners should verify licensure through the Contractors State License Board to ensure the company is in good standing.
Additionally, we recommend reviewing guidelines from the Federal Trade Commission on hiring contractors to understand your rights and best practices.
