About Downtown Portland Fox Tower
Downtown Portland Fox Tower is a mixed-use office/retail tower located in downtown Portland, Oregon. The property is owned by Unico Properties, a Seattle-based real estate investment and management company with properties across the western United States.
The building sits in the core of downtown Portland, a location that brings specific permitting requirements. Any exterior modifications to the building require Design Commission review, a process that can add weeks to your timeline. Interior tenant improvements route through the Portland Bureau of Development Services without Design Commission involvement.
The TI Permit Process at Downtown Portland Fox Tower
Tenant improvement permits at Fox Tower follow a five-step process. Each step is required. Skipping any step will delay your project.
- Landlord Letter of Authorization from Unico Properties’ tenant coordination team. Before you can apply for a city permit, you need written authorization from Unico Properties. The tenant coordination team reviews your construction plans to verify they meet building standards and do not interfere with building systems. This approval typically takes 1 to 2 weeks after you submit complete plans.
- Architectural plans meeting Unico Properties’ design standards. Your architect must prepare construction drawings that comply with Unico’s tenant design criteria. These standards cover partition wall construction, fire-rated assemblies, electrical and plumbing connections, HVAC tie-ins, and fire protection system modifications. Unico will reject incomplete or non-compliant plans.
- Submit to Portland Bureau of Development Services for plan review. Once Unico approves your plans and provides the landlord authorization letter, you submit your permit application to the Portland Bureau of Development Services (BDS). Downtown Portland permits are submitted through the city’s online portal. You will need the building permit application, all construction drawings, energy calculations, and the landlord authorization letter.
- Address city comments and corrections. BDS plan checkers review your drawings for compliance with the Oregon Structural Specialty Code, Oregon Fire Code, and Portland-specific amendments. Most TI projects receive correction comments after the first review. Your architect addresses each comment, revises the drawings, and resubmits. The backcheck review typically takes 7 to 12 business days.
- Permit issuance and construction start. After BDS approves all plans, the city issues your permit. You pay the remaining permit fees, post the permit at the job site, and construction can begin. Building inspectors will visit the site at required milestones during construction.

FAQ
What permits do I need for a tenant improvement at Downtown Portland Fox Tower?
Most TI projects at Fox Tower require a building permit, electrical permit, plumbing permit, mechanical permit, and fire protection permit. The specific permits depend on the scope of your work. Interior wall construction, new electrical circuits, plumbing fixtures, HVAC modifications, or fire sprinkler relocations all trigger permit requirements. Contact the Portland Bureau of Development Services or a permit expediter to confirm which permits your project needs.
How long does the TI permit process take at Downtown Portland Fox Tower?
The full TI permit process at Fox Tower typically takes 6 to 10 weeks from application to permit issuance. This includes 1 to 2 weeks for Unico Properties landlord approval, 15 to 25 business days for the first round of BDS plan review, and 7 to 12 business days for backcheck after corrections. Projects with incomplete submissions or multiple correction rounds take longer.
Do I need landlord approval before applying for a permit?
Yes. Unico Properties must review and approve your construction plans before you can submit a permit application to the City of Portland. The Portland Bureau of Development Services requires a signed landlord authorization letter from Unico Properties with your permit application. Submitting without this letter will result in an intake rejection.
What is a Landlord Letter of Authorization?
A Landlord Letter of Authorization is a signed letter from the property owner (in this case, Unico Properties) that gives you permission to perform construction work in the leased space and to apply for building permits on their behalf. The City of Portland requires this letter for all tenant improvement projects. You obtain it from Unico’s tenant coordination team after they approve your construction plans.
