Exterior Alterations to Historic Structure at 484 Loreto Street

The City of Mountain View is reviewing a request for a Historic Preservation Permit to allow exterior modifications to a historically designated single-family residence located at 484 Loreto Street in Mountain View, California. The proposed work includes altering windows and doors, constructing a wood deck at the north (rear) elevation, and making structural changes to the east end of the detached garage, all on a 0.14-acre lot. The project is governed by the Secretary of the Interior’s Standards for the Treatment of Historic Properties and qualifies for a categorical exemption under California Environmental Quality Act (CEQA) Section 15331 for minor alterations to existing historic structures, eliminating the need for a full environmental impact review. The applicant, Martin Bettge and Xinning Ho, is required to submit a certified exemption finding and a Notice of Exemption to the County Clerk’s Office in San Jose and the Office of Planning and Research in Sacramento, with the filing period running from October 18 to November 15, 2025. All modifications must preserve the historic character of the property and comply strictly with the approved standards, with no new construction permitted. The project is not a federal procurement and does not involve FAR clauses, contract funding, or procurement-specific requirements such as pricing, payment terms, delivery schedules, or contractor certifications. Oversight is handled by the City of Mountain View’s Planning Department, with Diana Pancholi, Principal Planner, serving as the primary point of contact. No formal contract exists—this is a regulatory permitting process under state environmental and historic preservation law, with approval contingent on documented compliance rather than competitive evaluation or monetary exchange.
