Garden Grove 3-Bedroom / 2-Bathroom ADU Construction – Custom Ground-Up Build by THP Construction

THP Construction is proud to showcase our latest 3-bedroom, 2-bathroom Accessory Dwelling Unit (ADU) in Garden Grove, California, a ground-up build designed for long-term value, modern comfort, and superior craftsmanship. As one of the leading ADU builders in Orange County, THP Construction specializes in creating high-quality living spaces that maximize functionality, energy efficiency, and property value for homeowners throughout Garden Grove and surrounding communities.

This custom ADU was built to serve as a spacious secondary residence, offering a full home experience with three full bedrooms, two beautifully finished bathrooms, and an open-concept living, dining, and kitchen area. Every detail—from the structural layout to the material selections—was tailored to meet the homeowner’s vision while adhering to Garden Grove’s local building codes and California ADU regulations.

The kitchen features premium cabinetry, quartz countertops, energy-efficient appliances, and modern lighting, making it both practical and visually impressive. The living room flows seamlessly into the kitchen, creating a bright and inviting common area perfect for small families, tenants, or multi-generational living.

Both bathrooms include designer tile work, high-quality plumbing fixtures, walk-in showers, and contemporary finishes, bringing a high-end feel to the entire unit. Each bedroom is designed with comfort in mind, utilizing large windows for natural light, durable flooring, and efficient layouts.

Externally, the ADU features a modern architectural design with durable materials built to withstand Southern California weather conditions. THP Construction installed energy-efficient windows, insulation, roofing, HVAC systems, and low-maintenance exterior finishes, ensuring long-term savings and sustainability.

This Garden Grove ADU project represents how a well-planned accessory dwelling unit can significantly increase property value, provide passive rental income, and support multi-generational living—three major reasons homeowners across Orange County continue to invest in ADU construction.

THP Construction handled every phase of the project, including planning, permitting, engineering, utilities, site preparation, construction, inspections, and final walkthrough. Our team is committed to delivering high-quality ADUs that look great, function flawlessly, and meet all legal requirements for the city of Garden Grove and the State of California.
