Initial analysis

The property at 1258-1260 48th Avenue in San Francisco's Outer Sunset neighborhood is a 3-story, multi-family residential building constructed in 1937, currently owned by Joanie Dang and containing two units. The building has undergone significant maintenance and renovation work over the past several years, with particular attention paid to addressing dry rot issues. In 2018-2019, extensive repairs were undertaken to the rear of the building, including removal of siding, installation of new stucco, replacement of windows and doors, and remediation of dry rot affecting approximately 80% of the exterior plywood and several framing members. The front of the building received attention in 2021 with the replacement of eight windows and stucco work, involving wood aluminum clad materials, at a cost of $40,000. Earlier improvements include a major horizontal and vertical addition proposed in 2002 (valued at $450,000) and a comprehensive electrical system upgrade in 2003, which included installation of 22 lights, 25 switches, and 60 receptacles.

The building's maintenance history shows a proactive approach to addressing structural issues, though the property has experienced several parking-related challenges in recent years, with multiple reports of driveway blocking incidents between 2019 and 2024. The most recent complaints, all related to parking violations, occurred between October 2024 and January 2024, with varying outcomes including citations issued and officers unable to locate the offending vehicles. The only non-parking issue recorded was a situation regarding illegal postings in 2019. Overall, the building's recent history demonstrates significant investment in structural improvements, particularly regarding moisture-related damage, though the property remains subject to ongoing parking management challenges.

Risk rating

How 1258-1260 48Th Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
