ADUs Approach

A Small Build With Big Impact

Designed for Your Lifestyle

From standalone backyard cottages to basement conversions, we tailor every ADU to your goals. We consider your property, needs, and budget to design a space that feels intentional and adds lasting value.

Navigating Permits + Regulations

ADUs in Oregon and Washington come with specific zoning and permitting requirements. We take the stress off your plate by managing approvals and ensuring your project complies with city codes -so construction moves forward without costly delays.

Crafted With Precision

Our team delivers thoughtful layouts, high-quality construction, and finishes that complement your existing home. The result: a space that feels like a natural extension of your property, not an afterthought.

An accessory dwelling unit (ADU) isn’t just an add-on – it’s an opportunity. Whether you’re creating rental income, making space for family, or simply adding flexibility to your property, an ADU should feel thoughtful, efficient, and seamlessly integrated into your home and lot. At Fleschner Construction, we bring the expertise to design and build ADUs that are functional, beautiful, and built to last.

What sets us apart?

A thoughtful pre-construction process is the foundation of a successful project. By taking the time to identify every need, detail, and expectation upfront, we ensure clarity from the start and minimize surprises along the way. This proactive approach allows for accurate budgeting, scheduling, and coordination – resulting in minimal to no changes during construction. The outcome is a smooth, transparent experience where every decision supports the vision and integrity of the finished home.

How much will it cost?

ADUs

ADUs are a significant investment, often more complex than they appear due to permits, utilities, and site work. While costs vary based on size, location, and design, most of our ADU projects start in the low six figures and scale up depending on scope and finishes. We focus on projects where quality and longevity matter most – not quick, budget builds. From the beginning, we’ll set clear expectations so you understand the investment required and the value it brings to your home.
