TOWN OF LOS GATOS
HISTORIC PRESERVATION COMMITTEE
REPORT
MEETING DATE: 10/22/2025 ITEM NO: 3
DATE: October 17, 2025
TO: Historic Preservation Committee
FROM: Joel Paulson, Community Development Director
SUBJECT: Consider a Request for Approval to Construct Exterior Alterations (Window
Replacement) to an Existing Pre-1941 Single-Family Residence on Property
Zoned R-1:8. Located at 69 Hernandez Ave. APN 510-41-015. Request for
Review PHST-25-019. Exempt Pursuant to CEQA Guidelines, Section 15061
(b)(3). Property Owner: Phil Rolla. Applicant: Mike Tinsley. Project Planner:
Suray Nathan.
RECOMMENDATION:
Consider a request for approval to construct exterior alterations (window replacement) to an
existing pre-1941 single-family residence on property zoned R-1:8, located at 69 Hernandez
Avenue.
PROPERTY DETAILS:
1. Date primary structure was built: 1900 per County Assessor; 1910 (estimated) per
Bloomfield Survey
2. Bloomfield Preliminary Rating: , historic & some altered, but still a contributor to the
district if there is one
3. Does property have an LHP Overlay? No
4. Is structure in a historic district? No
5. If yes, is it a contributor? N/A
6. Findings required? N/A
7. Considerations required? Yes
BACKGROUND:
The County Assessor indicates that the residence located at 69 Hernandez Ave was constructed
in 1900, and the 1990 Bloomfield Survey estimates the construction date to be 1910
(Attachment 1). The residence appears on the Sanborn Fire Insurance Map in 1908, and the
residence's footprint remained consistent between 1928 and 1956 (Attachment 2).
PAGE 2 OF 4 SUBJECT: 69 Hernandez Ave/ PHST-25-019 DATE: October 17, 2025
DISCUSSION:
The applicant is requesting approval to replace all existing windows, which vary in material
(wood and vinyl) and style (fixed, casement, and double hung). The proposed window
replacement is one component of Building Permit for an interior remodel currently under
review by the Town. The project includes modification of some windows and the addition of
one new window. The proposal also includes the removal of a chimney (non-historic, according
to the applicant’s research), replacement of a wood door with a wood-framed glass door at the
street-facing rear entrance, and removal of one bay window along the street-facing west
elevation (Attachments 3 and 7). There are 32 existing windows, and the applicant proposes to
remove and reconfigure 15 of the windows, replace 17 windows, and add one new window,
resulting in a total of 33 new windows, featuring Marvin Ultimate aluminum-clad wood
windows in ebony (Attachments 3 and 7).
The applicant’s Letter of Justification states that the subject house has undergone significant
modifications over time, including the enclosure of the front porches that wrap around to the
side and the construction of a second floor (Attachments 3 and 5). The applicant notes further
that the window replacement would also provide a more cohesive look by correcting the
window proportions to match the original historic proportions.
The Residential Design Guidelines provides the following recommendations related to window
materials:
3.7.2 Match window types and proportions to the architectural style and to the
surrounding neighborhood
• Select window types to complement the style of the house. Each architectural style
generally has one or two window types that are traditional to the style. Double hung
windows, for example, are common features of Victorian and Craftsman Styles while
casement windows are seen frequently in Mission and Spanish Eclectic styles
3.7.3 Match window materials to the architectural style and to the surrounding
neighborhood
• Wood windows are common in Los Gatos. Wood is still the desired choice for styles that
traditionally used wood. However, today there are some window materials, such as vinyl
clad wood windows that are not noticeably different from wood at a short distance.
PAGE 3 OF 4 SUBJECT: 69 Hernandez Ave/ PHST-25-019 DATE: October 17, 2025
3.7.4 Design the windows with attention to matching the traditional details of the
architectural style
• Divided lights (i.e., larger window panes broken up into smaller pieces) are common in
many home styles found in Los Gatos. Use either vertical or square proportions for the
smaller window elements. Be consistent in the proportions (i.e., the ratio of the
horizontal to the vertical dimension) of the smaller panes. Do not use snap in flat grids
to simulate divided lights. Use either true divided lights or one of the newer window
systems that have dimensional muntins on both the exterior and interior of the glass
along with a spacer muntin between the panes of glass. Use consistently for windows on
all sides of the house.
4.8.2 Building Materials
• Composite, synthetic, metal, vinyl, plastic or fabricated/ imitation wood products,
painted brick or imitation used brick will generally not be approved. However, some
exceptions may be made on a case-by-case basis when the decision-making body
determines that the replacement is consistent with the appearance of the original
material and that a layperson would be unlikely to discern the difference. The burden of
proof will reside with the applicant. Material samples, photographs, and specific
locations where the material may be seen in use will all assist in the evaluation of
alternative materials.
4.8.4 Windows and Glass in doors
• Windows should be constructed of real glass, and window frames should be constructed
of real wood - not vinyl, metal, or plastic. Wood sashes may be vinyl or metal clad if the
window frame and dressing is designed consistent with the historic context of the
building.
CONSIDERATIONS:
A. Considerations
Sec. 29.80.290. Standards for review.
In evaluating applications, the deciding body shall consider the architectural style, design,
arrangement, texture, materials and color, and any other pertinent factors. Applications
shall not be granted unless:
For pre-1941 structures, the proposed work will neither adversely affect the exterior
architectural characteristics or other features of the property which is the subject of
the application, nor adversely affect its relationship, in terms of harmony and
PAGE 4 OF 4 SUBJECT: 69 Hernandez Ave/ PHST-25-019 DATE: October 17, 2025
appropriateness, with its surroundings, including neighboring structures, nor adversely
affect the character, or the historical, architectural or aesthetic interest or value of the
district.
CONCLUSION:
The applicant is requesting approval to replace 32 existing windows, which vary in material
(wood and vinyl). The project includes modification of some windows and the addition of one
new window. All new windows would be Marvin Ultimate aluminum-clad wood windows in
ebony. Should the Committee find merit in the request, a recommendation of approval would
be forwarded to the Community Development Director, and the project would be completed
with a Building Permit. The project would not return to the Committee.
FINDINGS:
B. Findings - related to a request for a determination that a pre-1941 primary structure has no
historic significance or architectural merit.
In evaluating a request for a determination of historic significance or architectural merit,
the Historic Preservation Committee shall consider the following:
1. The structure is not associated with events that have made a significant contribution
to the Town;
2. No Significant persons are associated with the site;
3. There are no distinctive characteristics of type, period or method of construction or
representation of work of a master;
4. The structure does not yield information to Town history; or
5. The integrity has been compromised such that the structure no longer has the
potential to convey significance.

Re: Response to Comments Dated October 1, 2025 – 69 Hernandez Avenue
Dear Mr. Nathan,
Pursuant to your comments dated October 1, 2025, please find attached photos
of 69 Hernandez Avenue for your review.
As noted in the historic evaluation prepared by Archaeological Resource
Management, the home has been heavily modified over time—both on the
exterior and interior—resulting in a non-cohesive floor plan. We are proposing
revisions to the interior layout to restore a more functional and cohesive plan. As
part of these revisions, several window locations will need to be adjusted, as
shown on the submitted Floor Plans and Exterior Elevations.
In addition, we propose to correct the window proportions to a more historically
appropriate vertical orientation. Due to past modifications, the existing windows
vary in style, operation, and material. To achieve a unified and consistent design,
we are proposing to replace all existing windows with Marvin Ultimate aluminum
clad wood windows in Ebony. A manufacturer photo is attached for reference.
The new windows will have no grids.
Thank you for your consideration. Please let us know if any additional information
is needed.
Sincerely,
Mike Tinsley, Architect
License #: C-30944

Current street view from Hernandez Ave. Page 15 of the Historic Evaluation prepared by Archeological Resource
Management, shows what the original home looked like (dated circa 1970). Since then, the Entry has been relocated,
the porch has been enclosed, and a new porch with a new roof constructed. We are proposing to replace these
windows with properly proportioned windows.

proportioned windows.

RE: HISTORIC EVALUATION OF THE RESIDENCE AT 69 HERNANDEZ AVENUE IN
LOS GATOS
Dear Mr. Rolla:
As per your request our firm is submitting the enclosed historical evaluation of the residence at
69 Hernandez Avenue in Los Gatos. Based upon the requirements of the Town of Los Gatos, a
methodology was designed which included the following services:
- an evaluation of the structures based on the criteria of the NRHP and CRHR
- an evaluation of the structures using the criteria of the Town of Los Gatos Historic
Preservation Ordinance
- State Historic Resources Evaluation forms (DPR 523) for the structures
The current proposed plans for the property include expansion of the 2nd floor addition,
demolition of the detached garage, and construction of a new garage with an ADU above.
The residence at 69 Hernandez Avenue is not currently listed in the California Register of
Historic Resources (CRHR), or the National Register of Historic Places (NRHP). In addition, it
does not appear to be eligible for listing in either of these registers.
The structure at 69 Hernandez Avenue is not located within a recognized historic district for the
Town of Los Gatos and is not currently listed within the LHP overlay. The structure was
constructed Circa 1900, and thus before 1941. However, the residence is lacking in historic
association and architectural interest and has been heavily modified from its original form.
Thus the structure at 69 Hernandez Avenue does not appear to be historically significant, and no
further recommendations are being made.
Sincerely,
Robert Cartier, Ph.D.

The land on which the subject structure now stands consists of a portion of the Rancho Rinconada De Los Gatos. In
1876, the subject property made up a portion of the lands of W. McCormick (Thompson & West 1876). By 1890 the
property was owned by the S. and L.G. Real Estate Association (Official Map of Santa Clara County, 1890). The
subject property consists of a portion of Lots 9 & 10 of Block 2, as shown on the “Map of Glen Ridge Park” dated April
11, 1891 (Book E of Maps, Page 97). Based upon County of Santa Clara Appraiser’s records, the residence at 69
Hernandez Avenue was constructed Circa 1900. The earliest known owners of the home were George and Elizabeth
Miller. George was born in 1862 in Ireland, and emigrated to the United States with his family in 1880. George and
Elizabeth are listed as residing on Hernandez Avenue in the US Census of 1920, where George is noted to be
employed as a farmer/orchardist.

Continued from P3a:
Exterior walls are surfaced with narrow horizontal wooden siding on the first floor, with wood shingle siding on the
second story addition. The original fenestration is wooden framed and primarily in a double-hung sash configuration,
however the majority of the windows appear to be non-original. The front façade features a recessed porch accessed
via a brick stairway, both of which appear to be non-original.
Continued from B10:
George Miller retained ownership of the property until his death on March 26, 1938. On September 27, 1938 the
property was granted by his estate to Bertha Goldstein (Book 899 OR, Page 231). Bertha Goldstein (later Bertha
Passavoy) owned the property until her death in 1979. On November 9, 1979 the property was granted by her estate
to Lillian Varadi and Eboly Frankel (Book E973 OR, Page 490). On May 22 of 1980 they granted the property to Brian
and Christina Barnett and Robert and Carol Palmer (Book F340 OR, Pages 82-84). The 2nd story was added to the
residence during their ownership of the property, in 1981. On October 22, 1981 the property was granted to Norman
and Nancy Nason (Book G405 OR, Page 747). On October 5, 1982 they granted the property to Dennis and Jocelyn
Penner (Book H063 OR, Page 739). Jocelyn Penner retained ownership of the property until April 24, 2025, when it
was granted to Phillip and Gwynne Rolla, who are the current owners (Assessor’s Doc#25803591).
Los Gatos Historic Building Inventory
The Los Gatos Town Code (Sec. 29.80.215) states that “The purpose of historic preservation is to promote the health,
safety and general welfare of the public through:
(1)The protection, enhancement, perpetuation and use of structures, sites and areas that are reminders of past
eras, events and persons important in local, State, or National history, or which provide significant examples of
architectural styles of the past or are landmarks in the history of architecture, or which are unique and \
irreplaceable assets to the Town and its neighborhoods, or which provide for this and future generations
examples of the physical surroundings in which past generations lived.
(2)The development and maintenance of appropriate settings and environment for such structures.
(3)The enhancement of property values, the stabilization of neighborhood and areas of the Town, the increase of
economic and financial benefits to the Town and its inhabitants, and the promotion of tourist trade and interest.
(4)The enrichment of human life in its educational and cultural dimensions by serving aesthetic as well as material
needs and fostering knowledge of the living heritage of the past.
(Ord. No. 1316, § 4.86.010, 6-7-76; Ord. No. 1328, 8-2-76; Ord. No. 2041, § IV, 2-2-98)
The Town of Los Gatos recognizes a structure as historic if any one of the following apply:
1. Any structure / site that is located within an historic district
2. Any structure / site that is historically designated within the LHP (Landmark Historic Preservation) overlay
3. Any primary structure constructed prior to 1941, unless the town has specifically determined the structure has
no historic significance or architectural merit
The structure at 69 Hernandez Avenue is not located within a recognized historic district and is not currently listed
within the LHP overlay. The structure was constructed Circa 1900, and thus before 1941. However, the residence is
lacking in historic association and architectural interest and has been heavily modified from its original form.

California Register of Historic Resources Criteria
A cultural resource is considered “significant” if it qualifies as eligible for listing in the California Register of Historic
Resources (CRHR). Properties that are eligible for listing in the CRHR must meet one or more of the following criteria:
1. Association with events that have made a significant contribution to the broad patterns of local or regional
history or the cultural heritage of California or the United States;
2. Association with the lives of persons important to local, California, or
national history;
3. Embodying the distinctive characteristics of a type, period, region, or method
of construction, or representing the work of a master, or possessing high artistic values; or
4. Has yielded, or has the potential to yield, information important to the
prehistory or history of the local area, California, or the nation.
A property may be automatically listed in the CRHR if it is formally determined eligible for the National Register of
Historic Places. Properties that are formally determined eligible for the NRHP are those that are designated as such
through one of the federal preservation programs administered by the California Office of Historic Preservation (i.e.,
the National Register, Tax Certification, and Section 106 review of federal undertakings).
The CRHR interprets the integrity of a cultural resource based upon its physical authenticity. An historic cultural
resource must retain its historic character or appearance and thus be recognizable as an historic resource. Integrity is
evaluated by examining the subject’s location, design, setting, materials, workmanship, feeling, and association. If the
subject has retained these qualities, it may be said to have integrity. It is possible that a cultural resource may not
retain sufficient integrity to be listed in the National Register of Historic Places yet still be eligible for listing in the
CRHR. If a cultural resource retains the potential to convey significant historical/scientific data, it may be said to retain
sufficient integrity for potential listing in the CRHR.
The property at 69 Hernandez Avenue is not currently listed on the CRHR. In addition the structure does not appear
to be eligible for inclusion in this register. The structure is not associated with significant events and thus it does not
appear to be eligible for listing under Criterion 1. The structure is not associated with the lives of historically significant
people, thus it does not appear to be eligible for inclusion under Criterion 2. The structure is an example of vernacular
architecture, however it is not a notable example of this style. Thus it does not appear to be eligible for listing under
Criterion 3. The structure does not appear to have the potential to yield information important to history, and thus
does not appear to be potentially eligible for listing under Criterion 4.

National Register Criteria
The National Register of Historic Places was first established in 1966, with major revisions in 1976. The register is set
forth in 36 CFR 60 which establishes the responsibilities of the State Historic Preservation Officers (SHPO), standards
for their staffs and review boards, and describes the statewide survey and planning process for historic preservation.
Within this regulation guidelines are set forth concerning the National Register of Historic Places (36 CFR 60.6). In
addition, further regulations are found in 36 CFR 63-66, 800, and Bulletin 15 which define procedures for determination
of eligibility, identification of historic properties, recovery, reporting, and protection procedures. The National Register
of Historic Places was established to recognize resources associated with the accomplishments of all peoples who
have contributed to the country’s history and heritage. Guidelines were designed for Federal and State agencies in
nominating cultural resources to the National Register. These guidelines are based upon integrity and significance of
the resource. Integrity applies to specific items such as location, design, setting, materials, workmanship, feeling, and
association. Quality of significance in American history, architecture, archaeology, engineering and culture is present
in resources that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and
meet at least one of the following criteria:
A. that are associated with events that have made a significant contribution to broad patterns of our history;
B. that are associated with the lives of persons significant in our past;
C. that embody distinctive characteristics of type, period, or method of
construction, or that represent the work of master, or that possess high artistic values, or that
represent a significant and distinguishable entity whose components may lack individual
distinction;
D.that have yielded, or are likely to yield, information important in prehistory or history.
Integrity is defined in Bulletin 15: How to Apply the National Register Criteria for Evaluation, (U.S. Department of the
Interior, National Park Service 1982) as:
the authenticity of a property’s historic identity, evidenced by the survival of physical characteristics that existed during
the property’s historic or prehistoric period. If a property retains the physical characteristics it possessed in the past
then it has the capacity to convey association with historical patterns or persons, architectural or engineering design
and technology, or information about a culture or peoples.
There are also seven aspects of integrity which are used. These aspects are:
1. location 5. Workmanship
2. design 6. Feeling
3. setting 7. Association
4. materials
The residence at 69 Hernandez Avenue is not currently listed on the National Register of Historic Places. In addition
the structure does not appear to be eligible for inclusion in this register. The property is not associated with any known
significant historical events, thus it does not appear to be eligible under Criterion A. The structure is not associated
with historically significant persons, thus it does not appear to be eligible for inclusion in the NRHP under Criterion B.
Although an example of vernacular architecture, it is not a notable example of this style and does not appear to be
eligible for inclusion under Criterion C. The structure does not appear likely to yield important historical information,
thus it does not appear eligible for inclusion under Criterion D.

Residential Design Guidelines 33
Town of Los Gatos BUILDING DESIGN3
3.8.3 Use traditional detailing
•Treat openings in walls as though they were constructed of
the traditional material for the style. For example, be sure to
provide substantial wall space above arches in stucco and
stone walls. Traditionally, wall space above the arch would
have been necessary to structurally span the opening, and
to make the space too small is inconsistent with the archi-
tectural style.
•Openings in walls faced with stone, real or synthetic, should
have defined lintels above the opening except in Mission or
Spanish Eclectic styles. Lintels may be stone, brick or wood
as suits the style of the house.
•Treat synthetic materials as though they were authentic.
For example, select synthetic stone patterns that place the
individual stones in a horizontal plane as they would have
been in a load bearing masonry wall.
•Select roof materials that are consistent with the traditional
architectural style (e.g., avoid concrete roof tiles on a Crafts-
man Style house.)
3.8.4 Materials changes
•Make materials and color changes at inside corners rather
than outside corners to avoid a pasted on look.
3.9 ADDITIONS/ACCESSORY BUILDINGS/SECONDARY
UNITS
•Site additions in the least conspicuous place. In many cases
this is a rear or side elevation - only rarely is it a rooftop.
•The existing built forms, components and materials should
be reinforced. Heights and proportions of additions and
alterations should be consistent with and continue the
original architectural style and design.
•Additions should be subordinate, and compatible in scale
and proportion to the historically significant portions of
the existing structure.
•When an addition or remodel requires the use of newly
constructed exterior elements, they should be identical in
size, dimension, shape and location as the original, and
Use stone or wood lintels over
openings in stone walls
Additions, accessory buildings and secondary
units should match the form, architectural
style, and details of the original house

should utilize the same materials as the existing protected
exterior elements.
•When an addition necessitates the removal of architectural
materials, such as siding, windows, doors, and decorative
elements, they should be carefully removed and reused in
the addition where possible.
•The introduction of window and door openings not char-
acteristic in proportion, scale, or style with the original
architecture is strongly discouraged (e.g., sliding windows or
doors in a structure characterized by double hung windows
and swinging doors).
•The character of any addition or alteration should be in
keeping with and subordinate to the integrity of the original
structure.
•The amount of foundation exposed on the addition should
match that of the original building.
•Do not add roof top additions where the roof is of historic
significance.
•Second floor additions are discouraged in neighborhoods
with largely one story homes. If horizontal expansion of
the house is not possible, consider incorporating a second
floor addition within the roof form as shown in the example
to the left.
•Second floor additions which are not embedded within the
roof form should be located to the rear of the structure.
•The height and proportion of an addition or a second story
should not dominate the original structure.
•Deck additions should be placed to the rear of the struc-
ture only, and should be subordinate in terms of scale and
detailing.
•New outbuildings, such as garages, should be clearly subor-
dinate to the main structure in massing, and should utilize
forms, materials and details which are similar to the main
structure.
•Garages should generally be located to the rear of the lot
behind the rear wall of the residence. One car wide access
driveways should be utilized.
Original structure
Addition incorporated into the roof
successfully adds space while respecting the
integrity of the existing house and the scale of
the neighborhood
Placing a two story addition to the rear can minimize its impact on the historic resource and the scale of the neighborhood
