MINOR ARCHITECTURAL REVIEW (MAR)
PURPOSE
A Minor Architectural Review (MAR) is a Type I process for proposed changes to a previously approved
Architectural Review (AR) governing any existing commercial, industrial, institutional, or common-wall residential
development. MARs are intended for small-scale modifications that will not substantially change the overall
appearance and operation of the subject site. The MAR process will result in a staff-level decision and does not
require public notice and/or comment. The procedure and criteria for MAR approval is described in TDC
33.020(3)(e).
In all cases, modifications must comply with all applicable Tualatin Development Code (TDC) standards,
particularly those pertaining to landscaping, lot coverage, parking, access and circulation, and community design,
described in TDC Chapters 73A through 73G.
Applicable building and engineering permits are to be reviewed following the Minor Architectural Review.
WHAT
An MAR is required for the following actions/modifications:
Exterior building façade modifications:
o Adding, removing, or modifying awnings and similar features;
o Adding, removing, or relocating doors and/or windows;
o Changing surface materials and/or building colors, including painting, murals.
Landscaping changes:
o Removal/replacement of ten or fewer trees included as part of a previously approved landscape plan;
o Modification of existing landscaped and/or un-landscaped areas.
On-site development changes:
o Building addition or accessory structure adding up to 200 square feet of gross floor area;
o Change in existing setback or lot coverage by up to 10 percent;
o Modifying an existing wireless antenna facility (e.g., adding/replacing antennas, adding/replacing
