STR Cost Segregation in Portland, OR
Portland STR cost segregation: map the accessory rental area before allocating household improvements. Review local resources, study records, and a property-specific planning example.
Map the accessory rental area before allocating household improvements
Portland’s accessory short-term rental guidance distinguishes permit and conditional-use paths. Keep the approved arrangement and actual room use in the property file rather than relying only on a platform listing. Portland accessory STR guidance.
Define the property study
For a basement suite or rented bedrooms, mark exclusive guest areas, shared laundry, access routes, and owner-only rooms. Give the preparer measurements and use dates. A whole-house project such as roof work cannot be described as serving only the rental suite simply because guests benefit from it.
Records that resolve the main questions
- Approved room layout and permit category
- Measurements of guest, shared, and personal areas
- Whole-house versus suite-specific improvement invoices
A scoping example
A homeowner replaces the roof and installs a compact kitchenette in the guest suite during the same month. Record separate scopes and service areas. The timing of payment does not make the two projects equivalent for allocation purposes.
Can I base the study only on the suite’s nightly rate?
No. Rental pricing does not establish component cost or the rental share of household assets. Use construction, acquisition, and actual-use evidence.
