Initial analysis

The 4-unit multi-family residential building at 1103-1109 Shrader Street, owned by Blanz Revocable Trust, is a 2-story apartment structure built in 1922 in the Parnassus/Ashbury Heights neighborhood. The building underwent significant improvements in 2000, including a comprehensive $90,000 renovation of kitchens and bathrooms in units 1103, 1105, and 1107, installation of 40 vinyl windows, and other upgrades. More recently, in November 2015, the property experienced multiple housing code violations that were subsequently abated by December 2015, including issues related to lead paint hazards, water damage, inoperable windows, and various fire safety concerns. A notable complaint from November 2015 reported leaking sinks and showers affecting a living room bay window, along with electrical outlet issues and possible mold concerns. The building's maintenance history includes various permits for improvements, such as vinyl siding installation in 2001 and street space work in 2011.

Recent history shows ongoing maintenance and environmental challenges in the vicinity, with multiple 311 calls in 2024 reporting issues such as illegal postings, garbage and debris, and graffiti near the property. A sewage backup incident was reported and resolved in December 2023. While there was one recorded fire incident involving a smoke detector malfunction (date unspecified) with no civilian injuries, the building's fire safety compliance has been a recurring concern, with multiple violations noted during the 2003 routine inspection related to fire sprinklers, combustible storage, and fire extinguisher requirements. The property's documented history suggests a pattern of periodic maintenance and compliance issues, particularly regarding plumbing, fire safety, and lead paint concerns, though many of these issues have been addressed and abated according to city records.

Risk rating

How 1103-1109 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.
