427-429 Parker Ave, San Francisco, CA 94118

The three-story multi-family residential building at 427-429 Parker Ave in the Lone Mountain neighborhood, owned by Joyce Leung, is a two-unit apartment structure built in 1937. The building's maintenance history shows a consistent focus on addressing deck-related issues, with significant repairs documented in 1999 and 2001 related to rot removal and decking replacement, though both these permits eventually expired.

The property underwent several permitted improvements in the mid-1990s, including a kitchen remodel in the upper unit in 1995, with associated cost increases and permit renewals, suggesting substantial interior upgrades during this period. More recent maintenance includes a reroofing project completed in 2008 at a cost of $9,800, and permit activity in 2015 primarily focused on administrative matters such as unit count verification and final inspection renewals, indicating efforts to bring previous permits to closure.

The building's recent history shows limited major structural work, with most activity being administrative in nature. There have been two street cleaning issues reported in the vicinity of the building, both related to loose garbage - one in 2018 and another in 2021 - though these were resolved through the Department of Public Works and are more indicative of neighborhood conditions rather than building-specific problems. The most recent permit activity, occurring in 2015, suggests that any major building improvements may be relatively dated, with no significant maintenance records available for the past several years.
