A TI is a lease obligation with a construction schedule attached.

The risk in tenant improvement work is rarely the construction. It is the gap between what the lease promised, what the allowance covers, and what the drawings actually require — discovered three weeks before the tenant expects keys.

We price early and honestly from a space plan, flag the items that will drive cost, and identify long-lead materials before they become the reason the date moves. Permitting gets started early, not after demolition.

Then we build it in an occupied building the way it has to be built: protected corridors, coordinated elevator and loading access, dust and noise managed, and other tenants able to run their businesses.

Who this is for

Built for the people responsible for the asset.

Commercial property owners and landlords

You need a build-out delivered on the lease date, within the allowance, without becoming your weekly problem.

Asset managers

You need TI spend controlled and reported consistently across a portfolio of leases.

Property management companies

You need a contractor who communicates with tenants professionally and keeps the rest of the building operating.

Tenants building out space

You have an allowance, a drawing set, and an opening date. We help you get all three to line up.

How it works

From space plan to keys.

  1. 01

    Review and budget

    We review the space plan or drawing set, flag cost drivers and long-lead items, and provide early budget pricing.

  2. 02

    Permit and procure

    Permitting is submitted and long-lead materials are ordered while final details are being resolved.

  3. 03

    Build the space

    Trades are sequenced, the building stays operational, and progress is reported to landlord and tenant.

  4. 04

    Inspect and deliver

    Final inspections, punch list, and closeout documents completed so the space is delivered ready to occupy.

FAQ

Questions owners and managers ask us.

Can you price a TI before the lease is signed?

Yes. Early budget pricing from a space plan helps you negotiate the allowance with real numbers instead of a guess you have to live with later.

Do you work from an architect's drawings?

Regularly. We build to stamped drawings, flag constructability issues early, and coordinate with the design team rather than building around a problem.

Can you work in a building with other tenants operating?

Yes. Off-hours work, dust and noise control, shared corridor and elevator coordination, and protected access are standard on occupied buildings.

Who handles permits and inspections?

We do, in both Washington and Oregon jurisdictions, including scheduling inspections and closing out the permit for your records.

How do you keep a TI on schedule when a lease date is fixed?

Long-lead items are identified and ordered at the start, the schedule is built backward from the delivery date, and slippage gets reported early rather than at the end.
