Program Requirements

Eligible Developments

To be eligible for the SDC Exemption Program, the applicant must have site control and the proposed development must meet the following affordability requirements (per Title 30.01 – Affordable Housing Preservation, Chapter 30.01.095):

  • Homebuyer income limit: 100% MFI
    Developments must serve households at or below 100% of the Median Family Income (MFI) for a family of four (currently $114,400 and adjusted annually; adjusted upward for households of more than four people)

  • Sale price cap: $455,000
    Units must sell for less than the price cap provided by City Code, Section 3.102.090 D.
  • Sales must be arm's length transactions. An arm’s length transaction is one in which the buyer and seller act independently and have no relationship (by blood, marriage or unrelated business dealings) to each other. An arm’s length transaction will be fair and equitable to all parties and will result in a fair market price.
  • Occupancy: Units must sell to homebuyers who will occupy the homes as the initial occupants. Properties receiving homeownership exemptions may not be rented.

Compliance Requirements

The Portland Housing Bureau (PHB) requires the applicant to comply with the terms and conditions outlined in their recorded Regulatory Agreement (view sample). The compliance requirements are as follows:

In order to prove the property is being sold to an income eligible homebuyer who will occupy the property, PHB must receive a Homebuyer Compliance Verification Form along with supporting documentation (see page two of the form) prior to the sale of the property. Income is evaluated based on a homebuyer’s current annualized income. In the event that the property is being sold to an ineligible homebuyer or over the sale price cap, the developer must repay the exempted SDCs plus interest and fees to the city of Portland SDC Bureaus.

Process Steps for Home Ownership Project Compliance Requirements:

  1. Homebuyer completes and signs the Homebuyer Compliance Verification Form and submits it along with supporting income documentation to PHB for review prior to the sale of the property. Generally the escrow officer handling the closing will help facilitate this step.

  2. Escrow officer completes and faxes or emails PHB a completed Homebuyer Compliance Verification Form and supporting documentation to request a demand statement prior to closing. If it is known that the homebuyer will not meet the requirements, the escrow officer submits an SDC Demand Statement Request Form.

  3. PHB reviews the forms and supporting documents within 10 business days and then emails a demand statement to escrow disclosing whether or not the homebuyer meets the affordability requirements and indicating if any repayments are due.* PHB demand statements are valid for 90 days.

  4. Escrow officer collects and pays the applicable amounts of any repayments due.

  5. Once PHB receives proof that the SDC Bureaus have been repaid and/or the property has sold to the verified homebuyer for the current price cap or less, PHB records a Release Agreement and the SDC Exemption Program requirements are released.

*Please note: The amount exempted in the Regulatory Agreement is an estimate only; do not use this figure to calculate repayments. Only a Demand Statement from PHB will list the correct repayment amounts. Any repayments due in the case of non-compliance will be charged a $250 processing fee by PHB and by each bureau requiring repayments. Repayments will be due based on the rate that was in effect at the time the complete building permit application was submitted, plus interest (currently 5.2%, based on the city’s interim rate effective as of July 1, 2014).
