Custom ADU Builders in San Diego
An Accessory Dwelling Unit (ADU) is more than just additional space—it’s an opportunity to expand your lifestyle and increase the value of your property. At KSH Construction, we design and build high-end ADUs in San Diego that feel like a natural extension of your home.
Whether you’re creating a guest house, rental unit, home office, or multi-generational living space, we ensure your ADU is thoughtfully designed, beautifully built, and seamlessly integrated with your existing property.
FEASIBILITY & PLANNING
Start with Clarity
We begin by evaluating your property, zoning, and potential layouts to determine what’s possible. From city requirements to design considerations, we guide you through the early planning phase and connect you with trusted architects and designers if needed.
DESIGN & PERMITTING
Designed to Fit Seamlessly
Your ADU should feel like it was always part of your property. We collaborate on design, layout, and material selections while managing the permitting process to ensure everything moves forward smoothly and efficiently.
CONSTRUCTION
Built with Precision
From foundation to final finishes, we manage every detail of construction with a focus on quality, cleanliness, and communication. The result is a refined, functional space that adds both value and versatility to your home.
Finshes
Refined in Every Detail
The finishing phase is where your ADU truly comes to life. From cabinetry and tile to lighting and fixtures, every detail is selected and executed with precision. We focus on creating a cohesive, high-end space that feels intentional, functional, and seamlessly connected to your main home—never like an afterthought.
Completed ADU
A Space That Works Beautifully
Your completed ADU is more than additional square footage—it’s a fully realized space designed to enhance how you live. Whether used for guests, rental income, or everyday living, it delivers comfort, flexibility, and long-term value while blending seamlessly with your property.
