- Matching roofline and siding
A range, not a quote.
Types of additions
A bump-out adds a few feet to one room, a second story adds a floor over part of the house, and a garage conversion turns existing space into a room. Setbacks and lot limits cap how far you can build, and your building office sets them.
What goes into an addition
An addition starts with plans and a permit, then the foundation, framing and roof, and last the siding, wiring, plumbing and finishes. The roofline tie-in and the siding match are priced separately. Old siding may no longer be made, so a match can mean new siding on the wall beside it.
Foundation and frost
Footings have to reach below the local frost depth, which your building office sets. Digging, concrete and engineering for the foundation are a large share of the price, and a bigger footprint costs more.
Radon
Spokane and Kootenai counties are both in EPA radon Zone 1, the highest of EPA’s three zones. That’s a county screening level; only a test tells you about a given home. An addition with a slab or a basement is worth testing once it’s finished.
Permits and engineering
An addition needs a building permit and can need engineered plans. We’ll go over permits for your project at the estimate. We’ll lay out the schedule for your addition before work starts.
Recent work
Do additions need an engineer?
Often, for the foundation and framing. The plans and permit come first.
How long does a home addition take?
It depends on size and design. We'll lay out the schedule for your addition before work starts.
Do additions add value to a home?
It depends on the addition and the neighborhood. A real estate agent or appraiser can tell you what similar homes have sold for.
Can you build a mother-in-law suite?
Yes, a suite with a bathroom and kitchenette is a common plan. Zoning can limit a second kitchen, so the permit office is the first call.

We cannot recommend Elite Construction enough. Sergey and his team (Elijah, Paul, and Sawyer) are top notch and were recommended to us from a friend. They are trustworthy, professional, amazing craftsmen, and pay so much attention to detail. Beyond that they are genuinely nice guys. They built us a beautiful new deck with a gable over part of it. It fits our house so nicely and looks like it's always been there. They also built us a custom fireplace/entertainment wall with privacy wall on both sides. It's just beautiful. They also installed a new slider with windows on either side and a new glass door. I will recommend them to everybody doing any home construction project.

You can definitely tell this company is about quality with the work they put in. They removed our old bathtub shower and installed just a shower. They made sure that the shower was going to be stable and level and took extra steps to ensure that in our really old house. Only thing I would say that could be improved is the communication on timelines between each step. But we will definitely be using Elite for future projects. I love my new shower!

Sergey and his team did a wonderful job on our basement remodel. He comminuted with us every step of the way and updated us about any delays or progress. His team was professional and very skilled. In the bathroom, we had a fully tiled steam shower installed that is spectacular. There are numerous custom carpentry projects and overall the basement is better than we anticipated. Sergey went above and beyond for us and I wholeheartedly recommend elite construction for projects big or small.

Sergey and his crew did a phenomenal job on our river house in St Maries. Even though they had to travel and bring supplies with them, they secured our foundation so that it will last, replaced our old deck with new Trex decking, and remodeled our master shower. We thought all of this would take the whole summer, but Elite got it handled in under 7 weeks. We are thrilled with the results and not only will ask Elite to come back, but have been recommending them to everyone in the area.

Elite Construction did an excellent job on the repair/remodel and siding of the front of our house. Eli, Roman, Daniel and the rest of Sergey's crew were very professional, friendly and very hardworking. They always showed up on time and communicated what they would be working on that day. After the project was completed the job site was left spotless with no nails or debris in sight. They were also able to start and complete the job before our scheduled start date which was an added bonus. I will continue to recommend Elite Construction to my family and friends and will absolutely hire them again for future construction projects.

We had a wonderful experience with Elite Construction from beginning to end. Sergey detailed every step, work began when scheduled and consulted us for things that came up unexpectedly. The workers were respectful of our home, and were well prepared to keep dust and debris from spreading throughout the house. We are very happy with the end result and would and have, highly recommend them for future projects.

We have hired Elite Construction & Remodeling several times for projects at our home and we'll keep doing it based off of Sergei and his crew's craftsmanship and professionalism. The projects have ranged from small to big and each one is done with care and in a timely manner. Our most recent collaboration with Elite was for our kitchen remodel and the process was smooth and the end product is outstanding. It looks smashing! The team did a great job keeping us updated on the timeline, how the work was coming along and arrived consistently each day when they said they would show up. As the kitchen remodel wrapped up, we told them that it would just be a matter of time until we find something else for them to do and we'd give them a call. I'm glad we found Elite to help us improve our home.
