Initial analysis

The 7-unit apartment building at 520 Shrader St in Haight-Ashbury, built in 1911, has undergone significant renovations and faced several maintenance challenges in recent years. Most notably, in 2019-2020, the property underwent substantial improvements including seismic upgrades, plumbing repairs, electrical upgrades, and fire alarm system modernizations. These improvements included replacing six wood double hung windows (2020), upgrading the fire alarm system to meet current codes (2019), and addressing various electrical and plumbing issues across multiple units. A significant tenant complaint from August 2020 raised multiple concerns including potential lead paint hazards, window issues, water pressure problems, and unsafe kitchen conditions, though many of these concerns appear to have been subsequently addressed.

The building's maintenance history shows regular attention to basic infrastructure, including reroofing in 2004, bathroom repairs, and various system upgrades. Several building violations were recorded in 2016-2020, primarily related to interior surfaces and security requirements, though these issues seem to have been resolved. The property has maintained compliance with major safety requirements, including a completed fire alarm system upgrade in 2019 that included low-frequency sounders and sprinkler monitoring capabilities. Recent 311 calls from 2022-2024 have primarily concerned street-level issues outside the building's direct control, such as sidewalk maintenance and waste removal, suggesting normal urban maintenance challenges rather than building-specific problems.

Risk rating

How 520 Shrader St'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.
