Clear & Objective Code Update

Introduction

A city-initiated project to update the Tualatin Development Code (TDC) to comply with Oregon Revised Statutes (ORS) 197A.400 requirements related to clear and objective standards for housing.

The purpose of this project is to perform a code audit for the City to identify areas of the code that are not in compliance with ORS 197A.400 and draft a package of text amendments to address each issue. The amendments will assist in the preparation of a hearings-ready development code that complies with ORS 197A.400 requirements related to clear and objective standards for housing.

Background 

ORS 197A.400 mandates that local governments regulate housing development using clear and objective standards, conditions, and procedures. The statute is intended to reduce discretionary barriers, uncertainty, delay, and cost that discourage housing development.

Project Scope

The objective of this project is to perform a code audit and finalize a hearings-ready code update that will bring City into compliance with ORS 197A.400 requirements related to clear and objective standards for housing.

The City of Tualatin received a technical assistance grant from the Oregon Department of Land Conservation and Development (DLCD) to complete this work, and is being assisted by consulting firm MIG.

Project Timeline

This project kicked off in July of 2025. The final code amendments adoption is planned in December of 2026.
