Add value to your property — fast. At Duwin Development Group, we specialize in designing and delivering high-quality accessory dwelling units (ADUs) with a focus on speed, efficiency, and long-term ROI.
Why choose us
Rapid project delivery: Streamlined permitting, proven contractor networks, and modular-ready designs let us complete many ADU projects in a fraction of the typical timeframe.
Turnkey process: We handle everything from site assessment and design to permitting, construction, inspections, and final handover. One point of contact — fewer delays.
Cost-efficient solutions: Prefabrication options, standardized building packages, and strong supplier relationships reduce construction costs and keep budgets predictable.
Compliance and expertise: Our team navigates local zoning and building codes, ensuring your ADU meets all requirements and avoids costly rework or permit holdups.
Customizable designs: Choose from smart, space-efficient floor plans tailored for rentals, multigenerational living, or home office use — all optimized for maximum livability on compact sites.
Quality craftsmanship: Licensed contractors, vetted subcontractors, and rigorous quality control mean durable, energy-efficient ADUs that hold value over time.
How we accelerate timelines
Immediate feasibility review: We assess your lot and utilities quickly to identify constraints and opportunities.
Pre-approved plan library: Select from proven layouts to bypass lengthy custom-design phases when speed matters.
Parallel workflows: Permitting, site prep, and off-site fabrication occur concurrently to compress total schedule.
Dedicated project manager: Proactive scheduling, daily coordination, and clear milestone tracking keep your project on time.
Fast-track inspections: We coordinate with local authorities and use inspection-ready documentation to minimize hold-ups.
Value proposition
Generate rental income faster: Start earning sooner with a shorter path from contract to tenant-ready.
Increase property value: Professionally constructed ADUs significantly boost appraisal and resale potential.
Reduce homeowner disruption: Efficient construction sequencing and off-site fabrication minimize noise and on-site time.
Flexible financing guidance: We can connect you with lenders experienced in ADU financing to keep your cash flow steady.
Next steps
Schedule a no-obligation site assessment.
Choose a plan (custom or pre-approved) and review a transparent cost and timeline estimate.
Start construction with a clear completion target and dedicated project manager.
Add an income-producing, valuable living space to your property without the usual delays. Contact Duwin Development Group today to get a fast, efficient ADU plan tailored to your site and schedule.
