Located at 109 Tait Avenue. APN 510-18-037. Minor Development in a Historic District Application HS-25-009. Exempt Pursuant to CEQA Guidelines, Section 15301: Existing Facilities. Property Owner: Howard Labe and Jill Nakamura. Applicant: Terry J. Martin, AIA. Project Planner: Erin Walters. RECOMMENDATION: Consider a request for approval to construct exterior alterations to a non-contributing single- family residence in the Almond Grove Historic District on property zoned R-1D:LHP, located at 109 Tait Avenue. PROPERTY DETAILS: 1. Date primary structure was built: 1920 per County Assessor; 1940’s per Bloomfield Survey 2. Bloomfield Preliminary Rating: ‘N’ – New, probably built since 1950 3. Does property have an LHP Overlay? Yes 4. Is structure in a historic district? Yes, Almond Grove Historic District 5. If yes, is it a contributor? No 6. Findings required? No 7. Considerations required? Yes BACKGROUND: The County Assessor indicates that the residence was constructed in 1920, and the 1990 Anne Bloomfield Survey indicates a construction date of the 1940’s (Attachment 1). The property is included in the Sanborn Fire Insurance Maps having a consistent footprint between 1928 and 1956 (Attachment 2). Town records provide a permit history including a remodel with rough PAGE 2 OF 3 SUBJECT: 109 Tait Avenue/HS-25-009 DATE: May 23, 2025 N:\DEV\HISTORIC PRESERVATION\HPC Reports and Attachments\2025\05-28-25\Item 5 - 109 Tait Avenue\Staff Report.109 Tait Avenue.docx 6/4/2025 10:19 AM framing, new roof, new siding, new foundation, and electrical completed in 1961 (Attachment 3). Records include plumbing, lighting, and mechanical permits for a kitchen remodel and reroof completed in 1995. The applicant provided a request letter including photographs of the property (Attachment 4), a summary of the property research (Attachment 1), and project plans (Attachment 6) DISCUSSION: The subject property at 109 Tait Avenue is located on the northwest side of Tait Avenue, approximately 70 feet northeast of the intersection with Bean Avenue. The property is developed with a single-story main residence and a detached garage and accessory dwelling unit. The applicant is requesting approval to construct a new covered porch and exterior modifications to the main residence (Attachment 6). The proposed modifications include the following: • Reconfiguration and simplification of the existing multiple roof pitches at the rear and side elevations; • Construction of a new 354-squrae foot rounded covered rear porch and deck with wood posts and guard rails; • The addition of five new low-profile sun tunnels on the reconfigured roof; and • Reconfiguration of door and windows at rear and left side elevations to accommodate the porch access. New materials, composition roofing, wood trim, wood windows with painted mullions, vertical wood siding and all architectural characteristics will match the existing materials and architectural style. The proposed roof reconfiguration and rear porch addition will be located at the rear of the residence and will not impact the elevations visible from the street (Attachment 6). The proposed project appears to fall below the Town’s demolition thresholds for historic residences. Staff will verify this under review of the Building Permit. Town’s Residential Design Guidelines The Committee should consider Section 3.9 of the Town’s Residential Design Guidelines, which provides recommendations for construction of additions to existing residences (Attachment 5). Including but not limited to the following recommendations: • 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.

CONCLUSION: The applicant is requesting approval to construct a new covered rear porch and exterior modifications to an existing pre-1941 non-contributing single-family residence on property zoned R-1D:LHP in the Almond Grove Historic District located at 109 Tait Avenue. Should the Committee find merit in the request, a recommendation of approval would be forwarded to the Community development Director. Once approved by the director, the project would be accomplished through a Building Permit and would not return to the Committee. CONSIDERATIONS: A. Considerations Sec. 29.80.290.

Our area of work is at the rear of the historic residence at 109 Tait Avenue. At no point will we build above the highest ridge or make any changes visible from the front of the property. We propose to remove and replace several flat roofs that were piecemeal additions over the years; these roofs are failing and have significant issues with leaking. In their place, we propose a more simplified roof configuration. Five new low-profile sun tunnels will be added to bring light into the house. In addition, we propose to build a new 354 sf covered porch at the rear of the building. Several doors and windows will be reconfigured for porch access and will all match existing units. New materials, trim, and overall architectural characteristics will also match the existing house. Current landscaping will remain except as necessary, and any new plantings or hardscape will match existing. See attached photo elevations of each side of the residence. Again, no work is proposed to be visible from the front. We believe that the proposed work will not adversely affect the exterior architectural characteristics or any other features of the property. We request your consideration for approval of the proposed project. Should you have any questions, please don't hesitate to call or email. Best Regards, Terry J. Martin, A.I.A.

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 ATTACHMENT 5 Residential Design Guidelines34 Town of Los Gatos BUILDING DESIGN3 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
