Land Use and Zoning Oregon 3 Minutes Read · published February 08, 2026 Flag of Oregon

Overview

Portland, Oregon requires land division approvals for minor subdivisions (partitions) and any associated street layout or dedication. This guide explains who enforces the rules, the typical steps to apply, required submissions, and where to find official forms and policies. For detailed code and process notes consult the city planning and development pages noted below.[1]

Start early: survey and neighborhood constraints often drive the outcome.

When You Need a Minor Subdivision Approval

Minor subdivisions (partitions) are needed when an owner proposes to divide a property into a small number of lots or adjust lot lines in a way that creates new buildable parcels or affects street frontage.

  • Partition that creates three or fewer lots or adjusts lot lines where city code defines a partition.
  • Proposals that require new street dedication, public right-of-way changes, or new street segments.
  • Proposals that trigger public notice or neighborhood contact under local land use procedures.

Process & Timeline

Typical steps include a pre-application or consultation, preparing a survey and application materials, submitting to the Bureau of Development Services (BDS) or Bureau of Planning and Sustainability (BPS), technical review, any required public notice or hearing, final plat approval, and recording the plat with Multnomah County. Timelines vary by complexity and completeness of the application; check the department guidance for typical processing times.[2]

  • Pre-application meeting and site assessment to identify constraints and required permits.
  • Prepare and submit land division application, survey, and supporting documents.
  • Address technical review comments (engineering, stormwater, right-of-way).
  • Public notice or hearing if required by land use rules; receive decision.
  • Pay fees and record final plat with county to create new lots.

Penalties & Enforcement

Enforcement for unpermitted land divisions, illegal lot creation, or unauthorized street dedications is handled by the city code enforcement and development review functions. Specific fine amounts and daily continuing penalties are not specified on the cited enforcement page; see the city's code compliance information for remedies and enforcement procedures.[3]

  • Monetary fines: not specified on the cited page.
  • Escalation: information on first, repeat, or continuing offence penalties is not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to restore property, denial of permits, and referral to legal action or abatement.
  • Enforcer: Bureau of Development Services code compliance unit and related bureaus; complaints accepted via official code compliance contact channels.
  • Appeals: appeal routes and time limits vary by land use decision type; specific time limits should be confirmed on the decision notice or applicable code section (not specified on the cited page).
If you discover an unrecorded lot or street change, contact code compliance promptly.

Applications & Forms

Applications, checklists, and official forms for land divisions and street dedications are published by the city's development bureaus; use the official land-division application packet and follow the submission instructions on the bureau site.[2]

  • Application packet name: official land division/partition application (see bureau guidance for current packet name and checklist).
  • Fees: posted with the application packet or fee schedule on the bureau site; if a fee amount is not listed on the application page, it is not specified on the cited page.
  • Submission: follow online submission or in-person drop-off instructions on the bureau page.
A complete application and accurate survey reduce review cycles.
