It depends mostly on the size of the kitchen and how much of the layout changes. Materials, layout changes, electrical upgrades and finish choices all move the final cost, and keeping the existing cabinet layout costs less than removing walls. Every kitchen gets a written, itemized price for its own scope before work starts.

Size, layout changes and finish level move the price most. Moving plumbing or walls costs more than keeping the footprint, electrical upgrades add to it, and the materials and fixtures you choose set the finish level. Hidden problems found at demolition, such as outdated wiring, can also add work once walls are open.

Height and size, the decking material, railings and stairs, and what is underneath set most of a deck price. Height adds posts, bracing, guards and stairs, and every foot of guard and every step adds cost. Rotted joists, a failing ledger or new footings can turn a resurface into a rebuild, so we check the framing first.

Its starting condition, how many separate rooms you want, the plumbing and the finishes. Water marks, a low ceiling under the ducts or old wiring add work before any finish goes on. Every bedroom, office or bathroom adds walls, circuits and heat runs, and a drain that sits lower than the sewer line needs a pump.

How many rooms are included and which ones, what hides in the walls, the age of the house, and the finish level and layout moves. Kitchens and bathrooms weigh more than bedrooms and living rooms. Keeping plumbing and walls where they stand saves money, while moving a kitchen or removing a bearing wall adds to it.

Yes. You approve a written, itemized price before construction starts, so you know what the project includes and what it costs before you commit. The price is built for your own home and scope after we have seen the space, rather than taken from a standard package or quoted over the phone.

Yes. We build the scope and the material selections around your target budget, then you approve a written, itemized price before construction starts.

Yes. You can apply on our financing page, alone or with a co-applicant, before anything is designed. The application uses a soft credit check, which does not affect your credit score, and our office reviews it and contacts you about next steps. Kitchens, bathrooms, ADUs, additions and whole home remodels can all be financed.

Usually yes, once the work moves plumbing, wiring or walls. Seattle exempts minor repairs or alterations worth $6,000 or less in any six month period, but never work on a loadbearing support, and separate plumbing, electrical and mechanical permits may still be required even for work that needs no building permit.

Installing kitchen cabinets needs no building permit in Seattle, and neither do paneling or other surface finishes over existing walls. Moving or removing a loadbearing wall always needs one, and new plumbing, electrical or mechanical work can each need its own permit even when no building permit is required.

For most remodels, yes. Replacing a sink or toilet in the same place needs no permit, but tub and shower replacement does, and so does any fixture that needs new or changed water lines, drains or vents. Bellevue needs no building permit to replace kitchen cabinets or countertops, though plumbing or electrical permits may apply.

In Seattle, yes if the deck is more than 18 inches above the ground, is a roof deck or sits in an environmentally critical area, and most need only a subject-to-field-inspection permit. In Bellevue, a deck less than 30 inches above the ground needs no permit, and a higher one needs a permit with plan review.

Yes, with a permit. Seattle requires a permit for any work on loadbearing supports, no matter how small the project, and its code never counts removing or moving a loadbearing support as exempt minor work. The new beam or support is designed and shown on the permit drawings before the wall comes out.

Usually yes. Seattle's code requires a building permit before altering, repairing or improving a house, and SDCI says you need an addition or alteration permit to remodel, though a small project may qualify for a subject to field inspection permit. All work must meet the code even where no permit is required.

Yes, and the permit type depends on what is there now. Bellevue lists converting a finished basement into living or sleeping space as remodel work that usually needs no plan review. Converting an unfinished basement into living space falls under its remodel permit with plan review, alongside moving a loadbearing wall.

Yes, if the bedroom has an emergency escape opening. Seattle's code requires one in each new sleeping room created in an existing basement, with a net clear opening of at least 5.7 square feet, at least 24 inches high and 20 inches wide, and its bottom no more than 44 inches above the floor.

At least 7 feet for living space under Seattle's code, and at least 6 feet 8 inches for bathrooms, toilet rooms and laundry rooms. In a basement with living space, beams, girders and ducts may project down to 6 feet 4 inches above the finished floor. We measure under every beam and duct before placing rooms.

Often, yes. In Seattle, when alterations, repairs or additions that need a permit happen, or a sleeping room is added, the home must have smoke alarms as required for new homes. Exterior work such as a deck, windows or siding is exempt, and so is plumbing, electrical or mechanical work on its own.

No. Seattle says you do not need to upgrade existing portions of your house that are not being remodeled to current codes. The new work must meet current codes, any structural impact must be shown in the permit design, and permitted alterations bring the smoke alarms up to the rules for new homes.

At least 36 inches tall, wherever the deck surface is more than 30 inches above the floor or grade below at any point within 36 inches of the open edge. That is Seattle's code, and Bellevue's permit page gives the same 30 and 36 inch figures. Guards on the open sides of stairs may be 34 inches.

In Seattle, the city may issue a stop work order, and SDCI says that if you build without a permit, you may be fined up to $500 per day. Work started before a permit may get a special investigation inspection and fee before the permit is issued, and skipping the final inspection can also bring enforcement.

It depends on the size of the project and on your tolerance for inconvenience. Living on site during a renovation means dust, debris, noise and disruption, and bathroom facilities may be unavailable for a period, so for larger projects we generally advise arranging somewhere else to stay during construction.

Clear the work area and keep the rooms with no work in them as safe zones for daily life. Unfinished areas are sealed off with plastic sheeting to contain dust and debris, and it helps to plan for things like a temporary kitchen or bathroom while those rooms are out of use. Your project manager plans it with you.

Four steps. You schedule a call to share your vision, budget and timeline; we hold a consultation and send a tailored estimate; we design your space; then we manage construction, including permits, the budget and updates. Inside construction, work runs from demolition and rough-in through finishes to the final inspection.

One project manager runs your project from start to finish and is the person you can reach with questions. They keep you updated through each phase, review the schedule with you after the contract is signed, and coordinate the crew, deliveries and inspections, so you are not chasing several people for answers.

Yes. Design is one of our four steps, after the consultation and before construction. Our designer works through the layout, materials and finishes with you, and on kitchen projects space planning and layout design with our designer is part of the scope, so the plan is settled before anything is ordered.
