Detached Home: New / Addition

Building a new single-family detached home requires permits from both the Oregon City Planning and Building Divisions, and review from Public Works, as well. The permit process ensures that the new home is safe, complies with setbacks and zoning codes, and is not harmful to utility lines or public infrastructure.

For new home development within a Historic District, see the Historic Review Resources page for more information.

Please call 503-722-3789 or email the Planning Division with any Planning questions. You may also email Building Permits and email Public Works.

Review Process

New homes are subject to a typical two-week review for compliance with applicable Planning and Development Services Standards. They are also assessed System Development Charges by the Public Works Department.

Before you begin your project, please review the information guide included below. The fillable Planning Review application form is also included below.

Street & Public Improvements Requirements on Infill Lots

Pursuant to OCMC 16.12.011, public improvements including additional dedication of property and street and sidewalk improvements may be required for new construction and additions of more than 50%, if those improvements were not already constructed to current standards as part of a new residential land division or commercial project. These requirements are subject to maximum cost limitations and constitutional limitations. Modifications to these requirements may be requested through a Type II land use process. Contact the Public Works - Development Services staff for more information about public improvement requirements before finalizing your project design!
