Construction Services For Your DADU
Modera Services delivers expertly managed DADU construction from groundbreaking to final inspection, combining specialized building expertise with meticulous project management to create your investment property on time and within budget.
Professional Construction Management From Foundation to Finish
Building a DADU requires more than skilled trades. Our construction service provides comprehensive project management, quality control, and specialized DADU building expertise that ensures your project progresses smoothly. We coordinate every aspect of construction while maintaining the high standards your investment deserves.
Unlike general contractors juggling various project types, we focus exclusively on DADU construction. This specialization means proven building methods, established subcontractor relationships, and deep understanding of what works. Your project benefits from every DADU we’ve built before.
What Our Construction Service Includes
Complete Project Management
We manage every aspect of your build from scheduling and coordination to quality control and timeline management. Our systematic approach ensures all trades work in proper sequence, materials arrive when needed, and your project maintains steady progress toward completion.
Foundation Through Framing
We oversee all structural work including excavation, foundation pouring, framing, and roofing. Our experienced teams understand DADU-specific requirements for utilities separation, setback compliance, and structural integrity. Every phase meets or exceeds building codes and industry standards.
Systems Installation
We coordinate all mechanical, electrical, and plumbing installations with licensed subcontractors who understand DADU requirements. This includes separate utility metering, energy-efficient HVAC systems, and code-compliant electrical service properly sized for your DADU’s needs.
Interior & Exterior Finishes
From insulation and drywall through flooring and final paint, we manage all finish work to your specifications. Exterior siding, windows, and doors are installed with attention to weather resistance and energy efficiency. Interior finishes reflect your design choices while maintaining durability for long-term value.
Inspection Coordination
We schedule and manage all required inspections throughout construction, ensuring work is ready for review and addressing any items quickly. Our familiarity with local inspectors and their expectations helps avoid delays and ensures smooth approval at every stage.

Project-Specific Pricing
Construction costs vary based on size, site conditions, and finish level, but most DADU projects range from $200,000 to $350,000 completed.
We typically work on a management-fee model, where you pay direct costs to contractors and suppliers for greater transparency and potential savings. Alternatively, we can all do a fixed-price contract where we manage the entire project and include all costs (labor, materials, permits, etc.) in our quoted price.
Why Professional DADU Construction Matters
Predictable Timeline & Budget
Our specialized focus means accurate scheduling and realistic budgets. We know how long each phase takes, what challenges might arise, and how to maintain progress. This expertise minimizes surprises and keeps your project on track.
Quality That Lasts
Building for rental income or family use demands durability. We specify materials and methods that balance upfront costs with long-term performance, creating structures that maintain value and minimize maintenance.
Streamlined Communication
One team managing your entire project means clear communication and accountability. You have a single point of contact for questions, updates, and decisions, eliminating the confusion of coordinating multiple contractors.
Protected Investment
Proper construction protects your property value and ensures safe, comfortable living spaces. Our attention to detail, code compliance, and quality control safeguards your investment for decades to come.
Our Construction Process
Pre-Construction Planning
We finalize schedules, confirm subcontractors, order materials, and prepare your site for construction to begin.
Foundation & Site Work
Excavation, utility connections, and foundation work establish the base for your DADU with proper drainage and access.
Framing & Exterior
Structure goes up quickly as walls, roof, windows, and exterior finishes create your DADU’s weatherproof shell.
Systems & Insulation
Mechanical, electrical, and plumbing rough-ins are completed, inspected, and insulated for energy efficiency.
Interior Finishes & Completion
Drywall, flooring, fixtures, and final finishes transform your structure into a livable space, concluding with final inspections.
