Thinking About Building an ADU in Vancouver?
Building an accessory dwelling unit sounds simple until you’re the one doing it. Most homeowners in Vancouver don’t get stuck because they lack a good lot or a good idea. They get stuck in the gap between “I want an ADU” and “I have a permitted, buildable plan.”
A finished ADU adds real, usable square footage to your home without expanding the footprint. With the right planning, that means more space for the way your family actually lives in Vancouver:
- A home office that’s quiet and separate from the rest of the house
- A guest suite that gives visitors their own private space
- A playroom that gets the toys out of the main living area
- An entertainment space your family and friends actually want to spend time in
The square footage is already yours. Finishing it with a licensed contractor is one of the most practical investments you can make in your home.
ADU Building in Vancouver From a Team You Can Trust
Most ADU projects fail because contractors treat them like any other Project. Accessory Dwelling Units have their own challenges permitting, design, juggling sub contractors, and turning raw space into something truly livable and up to code.
Kieffer Projects is a local general contractor that specializes in thoughtful ADU building in Vancouver. We handle the entire project from design and permits through final inspection so you don’t have to juggle multiple trades.
Permitting confusion — Clark County and City of Vancouver ADU rules change often, and one wrong setback or utility hookup assumption can stall a project for months.
Juggling separate architects, designers, and contractors — miscommunication between three different companies means delays, finger-pointing, and change orders nobody budgeted for.
Vague, shifting estimates — “ballpark” pricing that turns into a very different number once framing starts.
Projects that drag on — every month of delay is a month of lost rental income, lost space for family, or lost time before you can move forward with your plans.

Who You’re Hiring for This Project
Kieffer Projects is a locally owned general contracting business serving Vancouver and the surrounding area. Accessory Dwelling Unit projects can go wrong when contractors treat them like standard projects, because ADU’s have their own structural, architectural, and code requirements.
We’ve Built ADU’s on everything from older homes with extra land to newer construction. That means we know how to work around low permitting, plan for design, and address potential issues before they become expensive problems. We don’t ignore the complications — we build the project around them.
Every ADU project we take on is managed by the same small team from the first walkthrough to the final inspection. We’re not a large franchise passing your job between crews. We’re a local business, and our reputation in Vancouver and nearby neighborhoods matters to us personally.
Kieffer Projects is licensed and fully insured on every job we take. We pull the permits and handle the inspections so you don’t have to worry about code compliance now or when you’re ready to sell.
