451 Monterey Blvd, San Francisco, CA 94112

The two-unit residential building at 451 Monterey Blvd in Sunnyside, owned by Jorge & Irma Perez since 2010, has undergone several significant maintenance and improvement projects since its construction in 1946. The property has received substantial plumbing upgrades, including a complete sewer lateral replacement in 2011, gas houseline extension in 2013, and most recently, a housetrap replacement from cast iron sewer to curb in 2021, demonstrating ongoing infrastructure maintenance.

The building has also seen some modernization efforts, including a kitchen remodel in 2005 and window replacement in the same year, both completed successfully. Recent issues have raised some concerns about resident experience, particularly a sewage backup incident in December 2021 and a bed bug infestation reported in June 2019.

The property has experienced recurring parking enforcement issues, with multiple complaints about driveway blocking between 2018 and 2024, though these are external matters not directly related to building conditions. The building's maintenance record shows regular upkeep of major systems, including electrical and plumbing, with all permitted work properly completed and inspected. The property's permit history indicates responsible ownership, with appropriate permits obtained for all significant work, including a street space permit in 2011 and various plumbing repairs over the years.
