Seattle office tenant improvement planning.
Connect the lease, existing conditions, design, permits, building rules, specialty trades, procurement, field work, and turnover before separate schedules create one shared delay.
· About 8 minutes
An office build-out starts with authority, not finishes.
The first planning question is not which carpet or light fixture to select. It is who controls the space, which documents govern the work, what the building will allow, what the existing systems can support, and which decisions must be approved before construction.
Seattle’s permit path depends on the project’s actual conditions and scope. A useful preconstruction plan keeps the lease and landlord requirements, design documents, permit strategy, construction scope, procurement, and move-in responsibilities connected.
Six workstreams that should agree before mobilization.
| Workstream | Decision needed early | Who confirms the path |
|---|---|---|
| Lease and base building | Define the landlord work, tenant work, delivery condition, allowances, approval rights, access, utility tie-ins, roof or shaft use, restoration duties, and required closeout documents. | Tenant, owner, landlord, property team, and their authorized representatives under the lease and work letter. |
| Existing conditions and test fit | Verify dimensions, approved use, accessibility, structure, utilities, equipment capacity, life-safety systems, hazardous-material information, and the assumptions behind the proposed layout. | Qualified design and project professionals with access from the property team. |
| Architecture and permits | Confirm the permit route, plan set, accessibility impacts, occupancy or use implications, required reviews, corrections, deferred submittals, and inspection sequence. | Seattle Department of Construction and Inspections with the applicant and licensed design professionals as required. |
| General construction and trades | Coordinate demolition, partitions, ceilings, doors, finishes, millwork, plumbing, electrical, mechanical, fire protection, controls, testing, and responsibility for every interface. | The general contractor and appropriately licensed specialty contractors under the project documents and applicable permits. |
| Building logistics | Document loading, elevator use, badging, working hours, noise, dust, shutdowns, protection, staging, waste, hot-work controls, and occupied-area separation. | Property management, building operations, tenant, and construction team. |
| Furniture, technology, and turnover | Align owner-furnished items, furniture, low-voltage, security, audiovisual, move activities, commissioning, training, punch work, warranties, and record documents with the construction schedule. | Tenant and its vendors with the property, design, and construction teams. |
For each item, identify the decision-maker, the information required, the due date, the submission or inspection owner, and the evidence that closes the task. A meeting note is not a responsibility transfer.
Move from a controlled space to a controlled turnover.
The exact path varies by building and scope. This sequence helps the project team expose missing decisions while changes are still less expensive to resolve.
Verify the space
Collect the lease and work letter, building rules, existing drawings and permits, field information, utility capacities, access constraints, and known owner or landlord work.
Freeze the working scope
Coordinate the test fit, finish and equipment direction, accessibility, building systems, specialty vendors, and owner-furnished items into one dated project basis.
Align approvals and releases
Connect landlord reviews, permit submissions, corrections, licensed trades, shutdown approvals, long-lead purchasing, and field start conditions to the schedule.
Build through closeout
Track inspections, testing, punch work, training, record documents, warranties, furniture and technology interfaces, and move readiness as construction deliverables.
Share enough context to replace assumptions with decisions.
- 01
Authority and property — address, suite, tenant entity, lease or work-letter boundaries, landlord and property contacts, building rules, and the people authorized to approve scope and cost.
- 02
Existing conditions — current photos, measured information, prior drawings or permit records, approved use, utility capacity, life-safety interfaces, and known hazardous-material information.
- 03
Planned use and design — headcount, working patterns, test fit, finish direction, rooms and equipment, accessibility, furniture, technology, security, and specialty-vendor requirements.
- 04
Approvals and logistics — design status, permit numbers, corrections, landlord reviews, loading and elevator rules, work hours, shutdown procedures, protection, staging, and occupied-area constraints.
- 05
Commercial controls — target occupancy considerations, budget basis, allowances and exclusions, long-lead items, owner-furnished purchases, decision dates, and turnover expectations.
Confirm the permit path with the authority for the work.
These official pages describe common Seattle construction, tenant-improvement, mechanical, and fire-alarm permit pathways. They do not determine the requirements for a specific project.
This planning guide is educational, not legal, code, design, lease, licensing, safety, environmental, or permit advice. Requirements can change and must be confirmed for the project’s actual address, building, use, design, and scope.
Make responsibilities visible before they become delays.
A useful answer identifies who decides, what the decision depends on, and what evidence allows the next activity to begin.
Does every Seattle office tenant improvement use the same permit path?
No. Seattle describes several pathways, including subject-to-field-inspection, blanket, and full construction permits. Eligibility depends on the actual address, existing approvals, proposed use, design, and scope, so SDCI and the qualified project team must confirm the route.
When should a general contractor join the planning process?
Early enough to test the scope against existing conditions, building logistics, shutdowns, long-lead items, phasing, permit assumptions, and the working budget. Early contractor input is useful only when it is coordinated with the tenant, property team, and design authority.
What changes when the building remains occupied?
Occupied work can add restrictions for access, noise, dust, elevators, loading, utility shutdowns, fire and life safety, temporary protection, work hours, and communication. Those rules should become written schedule and scope requirements before pricing and mobilization.
Who owns mechanical, electrical, and fire permits?
The answer belongs in a written responsibility matrix. The applicable authority and appropriately licensed design or trade professionals must confirm who prepares, submits, obtains, performs, inspects, and closes each portion of work.
Can a final construction price be reliable before the scope is coordinated?
Not usually. Pricing should identify assumptions, allowances, alternates, exclusions, unknown existing conditions, design dependencies, and owner-furnished items. A price becomes more reliable as those inputs are verified and the responsibilities stop moving.
Private commercial projects
Have an office space and a real project team?
Share the city and address, current plans or photos, intended use, known building criteria, permit status, and the construction scope that needs coordination. Evergreen Edge will help determine whether the work is a fit.
