Who it is for

Owners and managers of buildings that are already in use

Commercial remodeling changes a building you already own or run, rather than fitting out one leased suite.

Building owners refreshing common areas

A tired entry lobby, worn corridors and dated elevator landings shape how a building leases. Owners bring us in to rework shared spaces floor by floor while the tenants above keep their doors open.

Property managers with occupied facilities

Managers need a contractor who plans around tenant hours, protects finished areas, keeps exits clear and gives notice before shutdowns. Your tenants should hear about noisy days from you well in advance.

Business owners in their own building

Companies that own their premises remodel offices, break rooms, restrooms and customer areas without moving out. The work is sequenced so staff shift from one zone to the next instead of losing the whole space.

What we do

Commercial remodeling scope

One team handles demolition, framing, finishes and the trade permits, coordinated as a single schedule.

Lobbies and common areas

Entry lobbies, corridors, elevator landings and amenity rooms: new layouts, wall and ceiling finishes, lighting and flooring that hold up to daily traffic.

Whole floor renovations

Gutting and rebuilding an entire floor of an existing building, from demolition and new partitions to ceilings, doors and finishes, handed back ready for occupancy.

Restroom remodels

Partitions, fixtures, tile, lighting and ventilation replaced in shared restrooms, with clearances checked against the accessibility rules that an alteration can trigger.

Interior finishes

Drywall, acoustical and gypsum ceilings, paint, wall protection and commercial flooring, from one damaged wing to a building wide refresh.

Lighting, power and systems

Licensed electrical, plumbing and mechanical subcontractors relocate fixtures, outlets, diffusers and supply lines under their own permits, sequenced with the finish trades.

Permits and code upgrades

Drawings, permit applications and inspections for the building permit and each trade permit, plus the accessibility, life safety or energy work the city may require.

Minimal downtime

How we remodel a building that stays open

Occupied buildings set the pace. We plan the sequence first, then build to it, so you know which areas close and when.

  1. Existing conditions and permit path

    We walk the building with you, review the permit history and any asbestos survey, and confirm which permits the scope needs before the price is final.

  2. Phased plan and protection

    The work is divided into zones with dust barriers, protected routes and kept exits. Loud demolition and shutdowns go on the calendar, after hours or on weekends where you need it.

  3. Inspections and handover

    Each zone is inspected and walked with you before people move back in. The final inspection closes the permit and you get a punch list to sign off.

Local knowledge

Permits and code for commercial remodels

  1. The Seattle rule

    Remodeling a commercial interior needs an SDCI permit

    SDCI requires a construction permit to remodel a commercial building, including moving non structural walls or updating finishes. It reviews existing buildings under the Seattle Existing Building Code, and often requires accessibility improvements based on the scale and construction value of the project.

    What we do

    We check the permit history and existing conditions first, so any required accessibility or life safety work is in the scope before you see a price.

  2. The Bellevue rule

    Each trade needs its own permit

    Bellevue commercial building permits cover renovation of commercial buildings. Work that alters or adds to fire, plumbing, mechanical or electrical systems needs separate permits.

    What we do

    Our schedule lists every permit the job needs and who holds it, so no trade starts work ahead of its own approval.

  3. The regional rule

    An asbestos survey comes before demolition

    Puget Sound Clean Air Agency Regulation III, Article 4.02(a) requires an asbestos survey before renovating or demolishing a building. Outside owner occupied single family homes, an AHERA building inspector must perform it.

    What we do

    We ask for the survey report before selective demolition is scheduled, and build any abatement into the phase plan.

Washington requires every contractor to register with Labor and Industries (RCW 18.27.020). Our registration is VOLCABI792C6.

Questions

Commercial remodeling questions

What is the difference between commercial remodeling and a tenant improvement?

Commercial remodeling renovates the building or facility itself, often common areas, restrooms or whole floors for the owner. A tenant improvement fits out one leased suite for its occupant. Seattle treats both as alterations that need a construction permit. For suite work, see Tenant Improvements in Seattle.

Do I need a permit to remodel a commercial building in Seattle?

Yes. SDCI requires a construction permit to remodel a commercial building. Simple alterations may qualify for a subject to field inspection permit, while large projects and changes of use need a regular building permit. Electrical, plumbing and mechanical work carry their own permits. See the SDCI addition or alteration permit page.

Can the building stay open during a remodel?

Usually, yes. We split the work into zones, seal each one with dust barriers, keep exits and routes to them clear, and schedule demolition, core drilling and shutdowns after hours or on weekends when tenants need quiet.

Will a remodel trigger ADA upgrades?

It can. Under 28 CFR 36.403, altering an area with a primary function means the path of travel to it, and the restrooms serving it, must be made accessible as far as feasible, unless that cost exceeds 20% of the alteration. See ADA Compliance Upgrades in Seattle.

Is an asbestos survey required before a commercial remodel?

Yes. The Puget Sound Clean Air Agency requires an asbestos survey by an AHERA building inspector before a commercial building is renovated or demolished. In schools and child care centers built before 1978, the EPA lead renovation rule also applies.

Do you handle interior finishes only, without a full remodel?

Yes. Drywall repair, new ceilings, paint and commercial flooring can be a project on their own, from one corridor to a whole building. SDCI lists updating finishes in an existing retail store as an alteration, so we confirm the permit path before work starts.
