Initial analysis

The property at 3446-3450 19th Street is a three-unit, three-story multi-family residential building constructed in 1913, currently owned by Augustine David Peter. The building has undergone significant modernization and safety improvements in recent years, most notably between 2015-2017, when an extensive renovation project was completed including the installation of a new fire sprinkler system throughout the building, a private residence elevator, and substantial kitchen and bathroom remodels in units 3446 and 3448 ($40,000). Additional upgrades during this period included electrical system improvements (new panel, sub-panel, and numerous fixtures), plumbing upgrades including new kitchen and bathroom fixtures, and various structural enhancements including window replacements and mechanical system updates.

The building's recent history shows attention to safety and modernization, with no active building complaints since 2015 and no reported safety violations since that time. However, there is one significant historical complaint from 1999 regarding a broken pipe affecting the upper unit's kitchen sink. Recent maintenance issues documented through 311 calls have primarily concerned exterior matters such as graffiti, sidewalk cleaning, and a missing sewer vent cover, rather than building infrastructure or safety concerns. A tenant buyout was recorded on March 20, 2020, for 4 tenants totaling $24,200, suggesting either voluntary unit changes or building modifications. The property underwent substantial permitted changes including converting storage space to living space, adding exterior features, and performing foundation work, with all major permits showing completed or properly expired status.

Risk rating

How 3446-3450 19Th 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.

Neighborhood percentile

Out of 2380 buildings in this neighborhood, 809 are predicted to be safer.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast

Moderate concern 23.1%
Severe concern 25.6%
