From the initial consultation to the final walk-through, we ensure every step is handled with precision and attention to detail. Here’s an overview of our proven process for ADU construction.

Initial Consultation & Needs Assessment

We start with a comprehensive consultation to understand your vision, needs, and property specifications. Our team conducts a thorough site evaluation to assess feasibility, zoning regulations, and utility connections, ensuring a solid foundation for planning and permitting.

Design & Planning

Once we understand your ADU goals, we collaborate with architects and designers to create a functional and aesthetically pleasing plan. This phase includes layout design, material selection, and compliance with local building codes and regulations to ensure your ADU meets all necessary requirements.

Proposal & Budgeting

After finalizing the design, we provide a detailed proposal outlining the scope of work, timeline, and cost breakdown. We work closely with you to ensure the proposal aligns with your budget and expectations. Our transparent approach ensures no hidden costs—everything is clearly defined.

Pre-Construction & Permitting

Before construction begins, we handle all necessary permits, approvals, and site preparations. Our team ensures compliance with all local and state regulations, allowing for a seamless and efficient construction process. We also coordinate material procurement and finalize the construction schedule.

Construction & Execution

With approvals in place, we begin the construction phase, starting with site preparation, foundation work, and structural framing. From there, we proceed with roofing, insulation, plumbing, electrical, and HVAC installations. Every stage is executed with precision to ensure your ADU is built to the highest quality standards.

Quality Control & Inspections

Throughout the construction process, we implement rigorous quality control measures to ensure that every aspect of your ADU is completed with precision. Regular inspections are conducted to guarantee compliance with safety and building codes while ensuring the finished unit meets our high-quality expectations.
