Commercial Renovations
Commercial renovation is a different animal than residential remodeling – and it's a different animal than new commercial construction. The building is usually occupied, at least partially. There's a lease agreement that defines what can and can't be modified. There's a landlord who may need to approve the scope before permits go in. There's a business operating inside the space that has revenue depending on how the renovation gets sequenced. None of that shows up on a residential kitchen remodel.

Commercial Renovation Service Overview
Most commercial renovation projects fail one of three tests: the scope wasn’t defined against the actual existing conditions, the schedule didn’t account for landlord and permit review timelines, or the sequencing didn’t protect the client’s ongoing business operations.
Scope against existing conditions is the biggest one. A tenant walks a space with a contractor, describes what they want, gets a number, signs a contract – and then week two of demo reveals the HVAC ducting doesn’t support the new layout, the electrical panel is at capacity, or the existing plumbing is cast iron running the wrong direction for the new bathroom location. Every one of those is a change order. Every change order is a schedule slip and a budget hit. The right assessment catches most of these before the contract, not during demo.
Landlord and permit timelines get compressed in every commercial project we’ve ever quoted. The client’s business needs the space open by a specific date. The permit review takes what it takes. The landlord’s construction manager reviews plans on their timeline, not yours. Building these realities into the schedule upfront is the difference between a project that opens on time and a project that opens six weeks late with the tenant paying rent on both the old and new space.
Sequencing around operations depends entirely on the type of business. A restaurant renovating between dinner service and lunch service the next day has different constraints than a professional office renovating on weekends than a retail store renovating during off-season. We build the phasing plan to the operation – not a generic phasing template.

Commercial Renovation Cost – What Determines the Price
Commercial renovation costs range wider than almost any other construction category because the scope variables are wider. A cosmetic refresh of an existing office space – paint, flooring, some fixture updates – runs $15 to $35 per square foot. A moderate tenant improvement with new interior walls, updated lighting, some HVAC modifications, and finished spaces runs $65 to $130 per square foot. A full gut renovation with reconfigured plumbing, new mechanical systems, and specialized fit-out – restaurant kitchens, medical exam rooms, laboratories – runs $180 to $400 per square foot and sometimes higher.
The variables driving those ranges are honest ones. Mechanical, electrical, and plumbing modifications drive more cost than any category of finish work. Moving a bathroom is not the same price as painting one. Adding a commercial kitchen hood is not the same price as adding a break-room microwave outlet. When landlord requirements force upgraded building systems as part of the tenant improvement – accessibility compliance, sprinkler modifications, fire alarm tie-ins – those get itemized separately so the client sees what’s their scope and what’s the building’s scope.
We estimate in phases. Feasibility estimate after the initial walk-through with major assumptions flagged. Design-development estimate after preliminary drawings when the scope is defined. Contract estimate after permit-ready documents and existing-condition verification. Numbers tighten as the information gets better. That’s not evasive – that’s how commercial estimating actually works when it’s done honestly.
Our Commercial Renovation Services
From full replacements to targeted repairs, we provide comprehensive exterior solutions for homeowners across the Greater Seattle area.
Office and Professional Space Renovation
Tenant improvement work in office buildings – reconfiguring floor plans, updating conference rooms, modernizing reception and common areas, adding private offices to open plans or opening up private-office layouts to collaborative space. Work sequenced around occupied adjacent tenants and the client's own operations. We coordinate with building management on freight elevator access, after-hours work permissions, and any building-standard requirements before the schedule locks.
Retail Buildouts and Renovations
Storefront work, interior fit-outs, fixture installation, display wall construction, and back-of-house improvements. Retail projects live and die on the opening date – a store that opens two weeks late during holiday season loses margin that never comes back. Schedule commitments get built with buffer, and we surface slippage risk early rather than the week before opening. Landlord signage approvals and center-standard requirements coordinated before work starts.
Restaurant Renovation and Kitchen Fit-Outs
Front-of-house updates during operating seasons, back-of-house kitchen renovations during closure windows, and full restaurant transformations for concept changes. Commercial kitchen work involves health department review, ventilation requirements that most residential contractors underestimate, grease trap and plumbing configurations that follow local code, and specialized equipment coordination. We work with the equipment vendor's rough-in requirements from day one – not after the walls are up.
Rainwood also offers interior renovations. Contact us to discuss your project.

Why Hire a Commercial Renovation Contractor
The difference between a residential contractor who takes commercial jobs and a commercial renovation contractor isn’t always visible in a quote. It shows up in the pre-construction phase, the coordination with third parties, and what happens when something unexpected comes up during construction.
Pre-construction is where commercial projects are won or lost. Existing conditions verification, landlord approval workflow, permit strategy, and sequencing plan against client operations – all of these are pre-construction work that adds no visible progress on the site but determines whether the actual construction phase goes smoothly. Contractors who skip this phase to get to visible progress faster are the ones whose projects end up with change orders in month two.
The coordination layer is the other place experience matters. We’ve been through enough plan reviews, landlord reviews, and inspector interactions to know what triggers a review comment and what doesn’t. That knowledge shows up as fewer resubmissions, faster approvals, and inspection passes on the first visit rather than the third.

Great people. Showed up early and stayed late to get the job done. Work was excellent. Price was the best i found after four quotes. Would definitely use this company again.
We hired Rainwood Construction LLC to replace our French doors, and the result was outstanding. We knew going in this was more involved than a standard swap — we switched from inward to outward swinging doors, requiring extra attention to framing, flashing, and weatherproofing to keep everything sealed against water intrusion.Anatoliy was our point of contact and led the project from before to after, making sure the swing change and weatherproofing were planned and executed correctly. Igor and Vitaly handled the on-site installation and did excellent, high-quality work. The whole team was on time, professional, and delivered top-notch results. Can’t recommend them highly enough. 5 stars!
Every member of this crew I've had the pleasure of coming in contact with has been professional, excellent in their skillset, and fast. Pricing was reasonable for the excellent job they did.Last year we hired Rainwood to do plumbing and painting for a job. Both crews did such a great job, were thorough, and the level of detail was fantastic!We liked them so much we recently hired them for a quick job (installing ceiling fans). We messaged on a Wednesday and the job was done by Friday.Will absolutely hire Rainwood again and again for every job we do for our home.
Working with Rainwood Constructions on our house remodel was an excellent experience from start to finish. Their contractors were highly professional, skilled, and attentive to detail, and the quality of their work exceeded our expectations. The team communicated clearly throughout the project and ensured everything was completed on time without compromising quality. We’re extremely happy with the results and would highly recommend them to anyone planning a home remodel.
We had a very good experience with Rainwood Construction LLC and Toli during my brother’s home construction project in Shoreline. The team was professional, communicative, and paid close attention to detail throughout the process. We were especially happy with the quality of the fittings and finishing work, which turned out really well. The project was handled smoothly, and the overall workmanship met our expectations. Would definitely recommend them to others looking for reliable construction services.
We had an excellent experience with them on our sunroom project. The quality of the work was outstanding, they were easy to work with, and they clearly explained each step, the schedule, and key decisions (with various options to help us understand cost) along the way. Communication was solid from start to finish, and the final result looks great. Highly recommend, they are my new go to recommendation when friends ask.
Our Simple Process
From first contact to final walkthrough, we make siding projects straightforward and stress-free.
Feasibility Walk-Through
We walk the space with your program requirements – what you need the finished space to do. Ceiling tiles come up, panel schedules get reviewed, plumbing routes get identified, structural elements get located. The feasibility estimate comes out of what we actually see, not a phone description of the intended scope.
Design Development and Landlord Coordination
Preliminary drawings that define the scope enough to get landlord review started. Building-standard requirements identified early. Landlord construction manager engaged in parallel with design rather than at the end. Permit strategy defined based on the jurisdiction and the project category.
Permit-Ready Documents and Contract Estimate
Drawings developed to the level required for permit submission. Contract estimate reflecting the defined scope with existing-condition contingency broken out as a separate line item so the client sees what's contingency and what's base scope.
Closeout and Occupancy
Final inspections coordinated, punch list completed before turnover rather than after, closeout documentation delivered – as-built drawings, warranty information, equipment manuals, permit sign-offs. Occupancy walk-through with the client and building management before the space goes live.

FAQ
A cosmetic refresh runs $15 to $35 per square foot. A moderate tenant improvement with reconfigured walls, updated lighting, and finished interiors runs $65 to $130 per square foot. Full gut renovations with mechanical, electrical, and plumbing modifications run $180 to $400 per square foot, and specialized fit-outs like commercial kitchens or medical exam space go higher. The per-square-foot number depends more on the scope of MEP work than on the size of the space – which is why we itemize by system rather than quoting a blended rate.
A cosmetic refresh of an existing office runs three to six weeks. A moderate tenant improvement with permit-required work runs three to five months from contract to occupancy, and roughly half of that timeline is pre-construction – design, permit review, landlord approval. Full gut renovations run six to twelve months. Restaurant and medical fit-outs often run longer because of specialized inspection requirements. The permit and approval timeline is usually the pacing item, not the construction itself.
Depends on the scope and the jurisdiction. Cosmetic work usually doesn’t require sealed drawings. Structural modifications, MEP changes, and any change of occupancy classification usually do. We work with architects we’ve collaborated with before on projects that require sealed documents, or with your architect if you have an existing relationship. Bringing the architect into the feasibility conversation early saves cost later – retrofitting design decisions to fit unassessed existing conditions is expensive.
Depends on the scope and the operation. Office tenant improvement work often gets phased so occupied zones stay occupied while active zones get worked. Retail work can sometimes be phased around store hours with a temporary partition dividing sales floor from construction zone. Restaurant work usually requires closure windows for anything involving the kitchen or dining room – the sequencing gets built around the operation rather than the other way around. We work out the phasing plan during pre-construction, not on day one.
We pull the permits and coordinate with the landlord’s construction manager as part of the general contractor scope. That includes plan submission, review comment responses, and inspection scheduling. Landlord approvals for work that affects building systems – anything tying into base building HVAC, sprinklers, fire alarm, or life safety – go through their process on their timeline, which we manage in parallel with the permit process. The client sees status updates in the weekly meeting rather than being pulled into every back-and-forth.
Change orders happen on almost every commercial project – either because the client’s requirements shifted or because existing conditions revealed something the assessment didn’t catch. Our approach is to price and document change orders in writing before the work happens, not after. If a condition is discovered that requires a scope change, we stop the affected work, document the condition, price the change, and get the client’s approval before proceeding. The alternative – doing the work and pricing it after – is how commercial projects end up in disputes at closeout.
