How is Portland zoned?
Portland regulates land through 28 zoning districts, a compact roster for a city of its size, and the single dwelling districts state lot size directly: R2.5, R5, R7, R10 and R20.
R5 is the largest residential district at roughly 14,755 acres, with R7 at about 9,472 and R10 at roughly 6,010. R2.5 at about 4,477 acres is the notable one, since a 2,500 square foot single dwelling standard is a genuinely small lot for a detached house district.
Open Space is the largest classification at roughly 18,907 acres, more than any residential district, which for a city with Forest Park and an extensive natural area system is unsurprising but still striking.
The commercial and employment districts are organised by role and intensity: Commercial Mixed Use at 1, 2 and 3, Commercial Employment, Central Commercial, Central Employment and General Employment at 2. Naming both a central commercial and a central employment district distinguishes the downtown's retail core from its office fabric.
A Residential Farming district covers roughly 2,548 acres, an unusual designation in a city this size.
Industrial runs general at two levels covering roughly 9,815 acres and heavy at about 7,858, a very large industrial footprint reflecting the harbour and rail corridors. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
