Why We're the Right Choice for Your ADU Project

Building an accessory dwelling unit requires expertise in zoning, design, construction, and compliance. Our approach combines local knowledge with personalized service to ensure your project runs smoothly from concept to completion.

Our Comprehensive Planning Process

Before breaking ground, we evaluate your property's layout, setback requirements, and utility access to determine the best ADU placement. Our team coordinates with city planners to secure necessary permits and approvals, eliminating guesswork and delays. We present multiple design options that align with your budget, timeline, and vision—whether you prefer a modern studio or a two-bedroom family unit. This thorough planning phase prevents costly revisions and keeps your project on track.

Our Transparent Pricing and Timelines

We provide detailed, itemized estimates that break down material costs, labor, permits, and inspections so you understand exactly where your investment goes. Our contracts include realistic completion schedules with milestone checkpoints, and we communicate proactively about any changes that arise during construction. Unlike contractors who lowball initial quotes then add surprise fees, we build trust through honest pricing from day one. You'll never wonder about hidden costs or unexpected delays when working with us.

Our Commitment to Quality Craftsmanship

Every ADU we build uses durable materials selected for Orange County's climate—moisture-resistant drywall, energy-efficient windows, and insulation that maintains comfortable temperatures year-round. Our licensed tradespeople follow strict building codes and best practices, ensuring structural integrity and long-term performance. We conduct multiple quality inspections throughout construction, catching small issues before they become big problems. The result is an ADU that looks beautiful, functions flawlessly, and adds lasting value to your property.

Custom Solutions We Deliver for West Garden Grove Homes

Every property has unique opportunities and challenges. Our team tailors each ADU to fit your specific lot dimensions, existing structures, and intended use—whether housing family, generating rental income, or creating a home office.

Detached Backyard Units Built to Last

We specialize in ground-up construction of standalone ADUs ranging from 400 to 1,200 square feet, designed to complement your main home's architecture. These units include full kitchens, bathrooms, living areas, and private entrances—perfect for multigenerational living or long-term tenants. Our builders expertly handle foundation work, framing, roofing, and exterior finishes that withstand Southern California weather. Each detached unit maximizes natural light and outdoor access while maintaining privacy from the primary residence.

Garage Conversions That Maximize Existing Space

Many West Garden Grove homes have underutilized garages that can become comfortable living quarters with proper conversion. We handle structural modifications, insulation upgrades, and window installations to transform dark storage areas into bright, inviting spaces. Garage ceiling framing or refinishing is essential to create adequate headroom and proper insulation layers, especially in older structures where ceiling heights may need adjustment or outdated materials require replacement for energy efficiency and modern living standards. Our team ensures converted garages meet all residential building codes, including egress requirements and HVAC systems.

Prefab ADU Installation for Faster Completion

For homeowners seeking quicker turnaround times, we offer prefab ADU installation using high-quality manufactured units that arrive ready for site assembly. These factory-built modules undergo rigorous quality control before delivery, then our crew handles foundation preparation, utility connections, and final finishing touches. Prefab options reduce construction timelines by several months while maintaining the same durability and aesthetic appeal as traditional builds. We work with reputable manufacturers to ensure your prefab ADU meets California's strict energy efficiency and seismic standards.

How We Navigate Permits and Local Requirements

Orange County's ADU regulations can feel overwhelming, but our experience with West Garden Grove's specific zoning codes simplifies the process. We handle the bureaucratic details so you can focus on design choices and move-in plans.

Our Expert Permit Application Management

We prepare and submit all required documentation to the City of Garden Grove, including site plans, architectural drawings, and engineering reports that meet municipal standards. Our team stays current with California's evolving ADU laws and local amendments, ensuring your application includes everything needed for first-time approval. We coordinate inspections at each construction phase—foundation, framing, electrical, plumbing, and final walkthrough—scheduling these efficiently to avoid project delays. This proactive permit management eliminates the frustration many homeowners face when navigating city requirements alone.

Our Knowledge of West Garden Grove Zoning

We understand setback requirements, height restrictions, and lot coverage limits specific to different zones within West Garden Grove, from residential neighborhoods near Garden Grove Park to properties along Westminster Avenue. Our designers account for these regulations during the planning phase, creating ADU layouts that maximize square footage while staying compliant. We also advise on parking requirements and utility meter configurations that some contractors overlook, but can derail projects during inspection. This local expertise prevents costly redesigns and keeps your build moving forward.

Our Coordination with Utility Providers

Adding an ADU requires separate utility connections or upgrades to existing service—electricity, water, sewer, and gas lines all need proper capacity and legal hookups. Electrical rewiring and lighting installation for garage conversion projects often demands panel upgrades to handle additional load safely, and we coordinate with licensed electricians to assess current capacity, install dedicated circuits, and ensure all wiring meets National Electrical Code standards for residential occupancy. We manage communication with utility companies to schedule meter installations, service upgrades, and final inspections. Our established relationships with local providers expedite these processes, reducing wait times that can extend project timelines by weeks.
