Item 4 - Staff Report with Attachments 1-3.35 Tait PREPARED BY: SAVANNAH VAN AKIN, Assistant Planner 110 E. Main Street Los Gatos, CA 95030 ● 408-354-6874 www.losgatosca.gov TOWN OF LOS GATOS HISTORIC PRESERVATION COMMITTEE REPORT MEETING DATE: 12/14/2022 ITEM NO: 4 DATE: December 9, 2022 TO: Historic Preservation Committee FROM: Joel Paulson, Community Development Director SUBJECT: Requesting Approval for Construction of Exterior Alterations (Front Door Replacement) to a Presumptive Historic Residence (Pre-1941) on Property Zoned R-1D. Located at 35 Tait Avenue. APN 510-44-004. Request for Review PHST-22-021. APPLICANT: Dan Burnham. PROPERTY OWNERS: Steven & Katherine Erickson. PROJECT PLANNER: Savannah Van Akin. RECOMMENDATION: Consider a request for approval for construction of exterior alterations (front door replacement) to a presumptive historic residence (pre-1941) on property zoned R-1D located at 35 Tait Avenue. PROPERTY DETAILS: 1. Date primary structure was built: 1915 per County Assessor’s Database 2. Town of Los Gatos Preliminary Historic Status Code: N/A 3. Does property have an LHP Overlay? No 4. Is structure in a historic district? N/A 5. If yes, is it a contributor? N/A 6. Findings required? No 7. Considerations required? Yes BACKGROUND: The County Assessor lists that the residence at 35 Tait Avenue was constructed in 1915. The Sanborn Fire Insurance Map (Attachment 1) from 1908 indicates a primary structure existed with an accessory structure in the back right under a different address, 33 Tait Avenue. The 1928 Sanborn Fire Insurance Map show the current address, 35 Tait Avenue, with a primary dwelling unit and an accessory structure in the back left. At some point between 1928 and 1944, and Sanborn Fire Insurance Maps indicate the construction of a two-story addition to the rear of primary dwelling unit. The building footprint remained consistent from 1944 through 1956.

The new door would be installed within the existing opening, without increasing the size or modifying the shape of the existing door frame. The front door is not located on the front elevation of the house (Attachment 3). The Residential Design Guidelines provides the following recommendations related to door materials: 4.8.3 Doors •Original doors should be retained and restored. •New replacement doors for Victorians should not be flush, but of raised or flat panel design. •Front doors generally should be painted, not stained. Not applicable to Mission Revival/Mediterranean style structures. •Screened doors should be real wood framed of simple design unless patterns can be shown to fit the existing style. 4.8.4 Windows and Glass in doors •Original windows, glass and window decorations should be retained and restored. •Replacement of only the deteriorated portions of the windows is recommended rather than the replacement of the entire window. •New or replacement windows should be wood-sashed and muntined if applicable. •Sills, lintels, frames, sashes, muntins, and all decorations should be identically replaced. •All elements of new windows should be identical in size, shape, proportion, and dimensions as the original windows of the building, or consistent with traditional sizes, proportions and dimensions of buildings of the same architectural style, design and era. •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. •All lites (panes of glass) should be true divided lite, not artificial or snap -in grids. Simulated Divided Lite windows are permitted when the details of the window provide projecting muntin elements on the exterior and interior of the window along with a spacer muntin between the panes of glass (See example to the left). •New arched, angled, and/or octagonal windows are discouraged. •Large expanses of blank exterior walls without windows are discouraged. N:\DEV\HISTORIC PRESERVATION\HPC Reports and Attachments\2022\12-14-22 - SPECIAL 3pm\Item 04 - 35 Tait Avenue\Staff Report.35 Tait.docx PAGE 3 OF 4 SUBJECT: 35 TAIT AVE/PHST-22-021 DATE: DECEMBER 9, 2022 DISCUSSION (continued): As previously discussed with the Committee during review of similar requests, the fiberglass composite material was not available when the Guidelines were written, and it is silent on its use. The Guidelines emphasize the use of wood doors but allows exceptions for alternative materials when they are not noticeably different from wood at a short distance, found to be consistent with the historic context, and consistent with the appearance of the original material where it would be unlikely to discern the difference. The applicant requests approval of the fiberglass door materials. Photos of the existing door and proposed door have been provided (Attachment 2). Lastly, the proposed door is not located on the front elevation of the home, and the replacement would be in-kind in terms of shape and size, having a negligible impact to the exterior of the residence. CONCLUSION: The applicant is requesting approval for construction of exterior alterations (front door replacement) to a presumptive historic residence (pre-1941). Should the Committee find merit in the request, a recommendation 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. 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. B.Residential Design Guidelines Sections 4.8.3, and 4.8.4 of the Town’s Residential Design Guidelines offer recommendations for doors and windows on historic resources.
