Proposed Modifications
The applicant proposes to:
Add framed arches between the front porch columns 
Construct a 34-inch-tall pony wall between the porch 
columns 
Remove the existing dog-ear gable trim and replace it 
with stucco
These changes go beyond repair or replacement of 
deteriorated material and alter the building’s exterior design

Applicable Review Criteria
Mesa Zoning Ordinance requires COA decisions to be based 
on compliance with the Secretary of the Interior’s 
Standards for Rehabilitation
The proposal was determined to be inconsistent with 
Standards 1, 2, 3, 5, and 6
The City’s Historic Preservation Design Guidelines also 
provide applicable guidance for evaluating alterations to 
historic properties

The Secretary of Interior Standards
for Rehabilitation
Appeal of ADM26-00657
260 N Center St

Standard 1 : Minimal Change
The proposed alterations introduce additional changes to distinctive 
features and spatial relationships that are not required for continued 
residential use
The approved 2025 COA already provides for substantial rehabilitation 
needed to make the residence safe, habitable, and functional
Arches and a pony wall would alter the configuration and character of 
the front porch
Removing the dog-ear gable trim eliminates an existing distinctive 
feature 
These changes go beyond the minimal change contemplated by Standard 1

260 N Center St

Standard 2 : Historic Character
The house derives much of its character from:
Its simple form and modest scale 
Restrained architectural detailing 
Its straightforward, open front porch 
Distinctive gable detailing 
The proposed arches, pony wall, and removal of the dog-ear 
gable trim would collectively alter the character of the primary 
elevation.

Standards 3 and 5 : Historic Features and Design
Standard 3 : The proposed arches and pony wall are not supported by 
evidence that these features historically existed on this property.
Standard 5 : Distinctive features and craftsmanship that characterize the 
property should be preserved. 
The dog-ear gable trim is an existing distinctive feature
The simple porch design is also an important element of the 
property's character
Appeal of ADM26-00657
260 N Center St

Standard 6 : Repair & Replacement
Standard 6 : Deteriorated features may be repaired or replaced, but 
replacement should retain the historic feature's design and character
Dog-ear gable trim: Replacing the existing dog-ear trim with flat 
stucco eliminates the existing architectural feature rather than 
replacing it with a matching feature 
Porch columns/posts: Replacing a deteriorated square post with a 
compatible square post is consistent with Standard 6; changing the 
porch design to incorporate arched openings is not simply material 
replacement
The approved COA allows deteriorated materials to be replaced with 
compatible materials

Staff Recommendation
The proposed arches, pony wall, and removal of the dog-ear 
gable trim are inconsistent with MZO and Secretary of the 
Interior Standards for Rehabilitation 1, 2, 3, 5, and 6
The proposed modifications would substantially alter the 
architectural character of the primary elevation
Staff recommends that the Historic Preservation Board DENY 
the appeal and UPHOLD the decision of the  Historic 
Preservation Officer
