About Jason Allen Contracting, LLC
Jason Allen Contracting, LLC is a Portland-based contracting company that works with homeowners looking to make better use of their existing interior or exterior space. Whether the goal is to add an accessory dwelling unit or simply expand livable square footage, the company offers a range of services designed to guide clients through the development process.
The company operates within the framework of Portland Building Code, which distinguishes between ADU development and other forms of additional living space — two separate development paths that require different approaches.

A Practical Approach to Home Development
What sets Jason Allen Contracting, LLC apart is their involvement across multiple stages of a project. Rather than focusing solely on the construction phase, they engage with clients from the initial planning stages through to project completion. This includes helping homeowners think through technical decisions as well as aesthetic choices.
For those considering an ADU contractor in the Portland area, Jason Allen Contracting, LLC brings hands-on experience with the local permitting environment and building code requirements. Their work as an accessory dwelling unit builder is grounded in an understanding of what Portland's regulations allow and how to work within those parameters effectively.
The company's scope also extends to homeowners who may not be ready for a full ADU build but want to explore options like a garage conversion, an in-law suite, or other forms of added living space. Their consultation and master planning services are designed to help homeowners make informed decisions before breaking ground.
Jason Allen Contracting, LLC operates with a small, focused team, which allows for close client involvement throughout each project. Their work spans both structural and finish-level tasks, and they coordinate with specialists — such as designers and concrete professionals — when the scope of a project requires it.
