Initial analysis

The property at 1258-1260 20th Avenue in the Central Sunset neighborhood is a two-story, mixed-use building constructed in 1925, containing four residential units and ground-floor retail space. The building has undergone several significant transformations and safety improvements over the past decade, most notably the conversion of ground-floor retail space to childcare facilities in 2015, followed by further changes to personal services use in 2015-2016. Between 2012 and 2018, substantial fire safety upgrades were implemented, including the installation of comprehensive fire alarm systems, smoke detectors, horn strobes, and emergency lighting throughout the building, with the most recent installations completed in January 2018 costing approximately $4,800. The building has also received necessary plumbing and electrical upgrades, including bathroom renovations in 2010 and the installation of children's facilities in 2013.

Recent municipal service activity around the property has primarily involved typical urban maintenance issues, including general cleaning, sidewalk maintenance, and occasional reports of abandoned vehicles, with the most recent incidents occurring in 2024. The building's management has generally responded appropriately to maintenance and safety concerns, as evidenced by the timely completion of various permits and the resolution of a fire alarm system complaint in 2012. While there have been some issues with street cleaning and debris in the vicinity, these appear to be consistent with the urban environment rather than specific building management issues. The property's permit history shows regular maintenance and upgrading of facilities, with particular attention paid to fire safety and accessibility requirements.

Risk rating

How 1258-1260 20Th 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.

What the score means for you

Grade A–B — Low risk

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.

Grade D–F — High risk

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