We recently completed a major home renovation, which included bringing down walls, new kitchen, new windows, flooring throughout the house, a new patio French door, new front door, and we couldn't be more pleased with our contractor, Eran, and his entire crew. From our very first meeting, Eran made us feel comfortable and confident with his knowledge, vision, and approach. Taking on a large renovation can feel overwhelming, but he immediately put us at ease.
Throughout the project, communication was consistent and reliable. Eran was always available, responsive, and proactive in keeping us informed every step of the way. Given that our home was built in 1951, we expected challenges once the walls were opened--and there were. What stood out most was how quickly Eran and his team addressed issues, found practical solutions, and pivoted when needed, all while keeping the project on track.
Not only did they maintain a tight timeline, but the project was actually completed ahead of schedule. The quality of work and attention to detail exceeded our expectations. Eran truly brought our vision to life, and the end result is even better than we imagined.
We highly recommend Eran and his team to anyone looking for a professional, skilled, and trustworthy contractor.
Our place finally got the remodel it had been overdue for and the difference is huge. The crew showed up ready to work and kept things moving the whole time. Communication stayed clear and they respected the house during the process. It feels great walking through the space now.
Expand Your Living Space in Calabasas with a Custom ADU
Calabasas, home to landmarks like The Commons at Calabasas and Calabasas Lake, is known for its beautiful residential communities, spacious homes, and growing demand for flexible living spaces. As property values continue to rise and families look for smarter ways to utilize their property, many homeowners are choosing to add Accessory Dwelling Units (ADUs).
At Royal Home Remodeling, we design and build high-quality ADUs that blend perfectly with your existing home while maximizing functionality and property value.

From concept and permits to construction and final finishes, we handle every step of the process so your ADU project in Calabasas is smooth, efficient, and built to last.
Why Calabasas Homeowners Are Investing in ADUs
Calabasas homeowners often need additional space without moving to a new property. ADUs provide a smart solution that fits the lifestyle of many residents in this area. With larger lots, private neighborhoods, and increasing housing demand, building an ADU is both practical and financially beneficial.
Families often build ADUs to accommodate aging parents, adult children, or long-term guests while maintaining privacy. Others use these units as rental properties, home studios, or work-from-home offices. In a city like Calabasas where property space is valuable, adding a well-designed ADU can significantly increase both usability and home value.
Our team at Royal Home Remodeling carefully plans each project to match the architectural style of your home and the unique layout of your property, ensuring the final result looks natural and cohesive.

Types of ADUs We Build in Calabasas
Building an ADU requires thoughtful planning, local code compliance, and skilled construction. Our Pasadena team focuses on creating spaces that are comfortable, efficient, and designed for long-term value.
Custom ADU Design and Planning
Every property in Pasadena has unique dimensions, zoning guidelines, and homeowner goals. We begin with a personalized design process that considers your lot size, layout, and how the ADU will be used. From detached backyard cottages to garage conversions, we ensure the design complements your home while maximizing usable space.
Garage Conversion ADUs
Many Pasadena homes have underused garages that can be transformed into modern living spaces. Our garage conversion services convert existing structures into comfortable, fully equipped ADUs with insulation, plumbing, electrical upgrades, and stylish interiors.
Detached Backyard ADUs
Detached ADUs are popular for homeowners who want a private and independent living area. These standalone units provide flexibility for rental income, guest housing, or multi-generational living while maintaining privacy for both the main house and the ADU occupants.
Types of ADUs We Build in Calabasas
Detached Backyard ADUs
A detached ADU is a separate small home built on your property. These units are perfect for rental income, guest accommodations, or private living spaces for family members.
Garage Conversion ADUs
Many homes in Calabasas have large garages that can be transformed into fully livable units. Converting an existing structure often reduces construction time while still providing a comfortable and independent living area.
Attached ADUs
Attached ADUs connect directly to the main home but maintain their own entrance and living space. This option is ideal for homeowners who want easy access between the main house and the additional unit.
Custom Luxury ADUs
Because Calabasas properties often feature premium architecture and landscaping, many homeowners prefer ADUs designed with upscale finishes, modern layouts, and high-end materials that complement their main residence.
Benefits of Building an ADU on Your Property
Adding an ADU provides several long-term advantages for homeowners in Calabasas.
- Increase overall property value
- Create rental income opportunities
- Provide independent living space for family members
- Add flexible rooms for offices, studios, or gyms
- Maximize unused backyard or garage space
Our design team ensures every ADU is optimized for comfort, functionality, and visual harmony with your existing home.

Signs Your Property Is Ideal for an ADU
Many Calabasas homes have the perfect conditions for an accessory dwelling unit. If your property includes extra backyard space, a large garage, or unused areas around the home, an ADU could be a practical upgrade.
Homeowners often consider building an ADU when they need additional living space but prefer not to relocate. Others see it as a smart investment that creates passive rental income while increasing the long-term value of their property.
With proper planning, an ADU can become one of the most useful and valuable features of your home.

People Also Ask
When building an Accessory Dwelling Unit, homeowners often overlook critical zoning setbacks and utility connection requirements. A frequent error is underestimating the cost of separate utility taps, which can exceed $40,000 for water and sewer hookups. Many also fail to account for fire code clearances and parking space regulations specific to the San Fernando Valley. Another common mistake is choosing an unlicensed contractor, leading to permit delays and structural issues. For a detailed analysis of these financial pitfalls, please refer to our internal article titled Attached vs. Detached ADUs in Reseda: The $40,000 Utility Tap Fee Decision (Cost Breakdown & Hidden Risks). At Royal Home Remodeling, we always advise clients to budget for soil testing and impact fees before breaking ground, as these hidden costs can derail a project if not planned for in advance.
The new laws for ADU in California in 2026 focus on streamlining the approval process and increasing affordability. Key changes include allowing ADUs to be built on lots with existing single-family homes without requiring additional parking if the property is within a half-mile of public transit. Additionally, the minimum setback requirements are reduced to four feet from the side and rear lot lines, and owner-occupancy requirements are permanently eliminated. These updates aim to simplify construction and expand housing options. For homeowners in Van Nuys and the San Fernando Valley, Royal Home Remodeling can help you navigate these updated regulations to plan your ADU project efficiently.
For homeowners in the San Fernando Valley, the cheapest option for an Accessory Dwelling Unit is typically a prefabricated or "prefab" model. These units are built off-site in a factory, which reduces labor costs and construction time significantly compared to a fully custom build. However, the lowest upfront cost does not always mean the best long-term value. You must factor in site preparation, foundation work, utility hookups, and permits, which can add tens of thousands of dollars regardless of the unit type. For a detailed comparison of costs and benefits, we recommend reading our internal article titled ADU Prefab Vs. Custom Build: Pros And Cons For Valley Homeowners. Royal Home Remodeling advises all Valley homeowners to get multiple quotes and consider total project expenses, not just the base price of the unit.
