Unlock Your Property’s Untapped Investment Potential
An Accessory Dwelling Unit (ADU) is more than just extra space; it’s a powerful financial tool. For real estate investors and savvy homeowners in Kenmore, Kirkland, and across the Eastside, ADUs offer a direct path to maximizing property value, generating consistent rental income, and building long-term equity. We specialize in turning underutilized land into profitable assets.
Maximize Property ROI
A strategically designed ADU can significantly increase your property's market value and appraisal, providing an immediate boost to your equity.
Generate Passive Rental Income
Create a steady revenue stream by leasing your ADU to long-term tenants or listing it as a short-term rental in high-demand areas like Bellevue and Redmond.
Capitalize on New WA Laws
We are experts in navigating the latest state and local regulations, including opportunities to build two ADUs on a single lot, doubling your investment potential.
Flexible & Modern Living Spaces
Beyond rental income, ADUs provide flexible solutions for multi-generational living, a private home office, or guest accommodations, adding versatility to your property.
Your One-Stop Shop ADU Builder
Pelletier Construction offers a complete, seamless solution for ADU development. We manage every detail from initial site evaluation to final handover, ensuring your project is efficient, on-budget, and optimized for maximum return. Our focus is on making the investment process seamless for you.
Detached ADUs (DADUs)
Often called backyard cottages or laneway houses, DADUs are standalone structures that offer the most privacy and highest rental appeal. We design and build custom DADUs that complement your main property while maximizing square footage and functional layout for future tenants.
Attached ADUs
An excellent, cost-effective option, attached ADUs can be created by converting existing space like a garage or basement, or by building a new addition to your home. These units are perfect for properties with space constraints and still offer significant rental income potential.
Two-ADU Development
Leverage the full potential of your investment property. We are one of the few Eastside ADU builders specializing in the strategic planning and construction of two accessory dwelling units on a single qualifying lot, turning one property into three potential income streams.
Feasibility, Design & Permitting
The planning phase is critical. We act as your primary resource, handling initial site assessments, navigating complex zoning laws in cities like Woodinville and Bothell, creating investment-focused designs, and managing the entire permitting process on your behalf.
A Smooth Path from Concept to Completion
We’ve refined our process to be fast, flexible, and completely transparent. We understand that for investors, time is money. Our goal is to move your project forward efficiently without sacrificing quality or communication.
ADU Strategy & Feasibility Consultation
We begin by understanding your investment goals. Our team assesses your property's potential, reviews local Eastside regulations, and provides a clear analysis of the costs, timeline, and potential ROI for your project.
Investment-Focused Design & Planning
Next, we create custom layouts designed to maximize rental income and appeal. We handle all architectural and engineering plans, ensuring every design choice aligns with your budget and financial objectives before a single nail is hammered.
Permitting & Pre-Construction
Our team takes the lead on submitting all necessary documents and managing communications with local planning departments to secure permits. This is also when we finalize material selections and build a detailed construction schedule to ensure a smooth start.
Efficient & Clean Construction
With permits in hand, our skilled subcontractors get to work. You'll have a dedicated point of contact who provides regular updates. We pride ourselves on maintaining a clean, organized, and efficient job site to minimize disruption.
Final Walkthrough & Asset Handover
Before completion, we conduct a meticulous final walkthrough to ensure every detail meets our high standards of quality. We then hand over the keys to your brand-new, income-generating asset, ready for you to rent or use.
ADU Development FAQs
We believe in empowering our clients with information. Here are answers to some common questions about building an ADU on the Eastside.
How much does building an ADU cost in the Kenmore or Bellevue area?
The cost of an ADU varies widely based on size, site conditions, and finishes. A detached ADU typically starts around $250,000-$300,000 and can go up from there. We provide a detailed, line-item budget during our feasibility phase to give you clear cost expectations.
Can you really build two ADUs on my property?
Yes, thanks to new Washington state laws, many single-family lots are now eligible for two ADUs (for example, one attached and one detached). We can perform a feasibility study to confirm what is possible on your specific property in Kirkland, Bothell, or other target cities.
How long does the full ADU construction process take?
The timeline depends on the project’s complexity and the local permitting process. Generally, you can expect the design and permitting phase to take 4-6 months, with construction taking an additional 5-8 months.
Do you handle all the permits and city inspections?
Absolutely. We are a one-stop shop for ADU development. Our service includes managing the entire permitting process, from initial application to coordinating all required city inspections throughout the build.
What is the potential rental income for an ADU on the Eastside?
Rental income depends on the location, size, and quality of the ADU. On the Eastside, it is common for new, well-designed ADUs to generate $2,500-$4,000+ per month in rental income, offering a significant return on your investment.
