Initial analysis

The two-unit multi-family residential building at 1549-1551 Shrader Street, owned by Marlon Ing, is a two-story flats and duplex structure built in 1946 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant improvements over the years, with substantial renovations occurring in 2010 including kitchen and bathroom remodels, window replacements, and roof work totaling over $38,000 in improvements. The building experienced a series of plumbing and electrical upgrades during 2010, with some permits ultimately expiring, and a correction notice was issued for exposed wiring issues which were subsequently resolved. A notable cluster of sewer-related incidents was reported in early 2020, with multiple sewage backup issues between January and April, while more recent infrastructure concerns include a potentially collapsed sidewalk reported in December 2021.

Of particular concern are two sets of complaints from May 2020 regarding unpermitted construction work, with neighbors reporting nearly daily construction noise from wood chipper, circular saws, and nail guns, as well as safety concerns about children using a makeshift structure on top of a shed. These complaints were filed during the COVID-19 lockdown period when construction activities were generally restricted. Other recorded issues include a window compliance violation in June 2010, a blocked exit fire complaint in 2018 (which was corrected), and periodic tree maintenance and sidewalk issues. The building has maintained general compliance with permits and inspections, with most historical improvements reflecting proper documentation and completion, though some permits from 2010 show as expired rather than completed. A recent tree maintenance issue was reported and resolved in November 2023, and parking-related service requests were filed in 2021, indicating ongoing infrastructure maintenance needs in the surrounding area.

Risk rating

How 1549-1551 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.
