Initial analysis

The property at 1501 19th Ave in the Central Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1904, currently owned by Tammy Thuan Zitun Lvg Tr. The building has undergone several significant modifications and improvements over the years, with the most recent being the approval of a new three-bedroom ADU (Accessory Dwelling Unit) in late 2021 at a cost of $271,184. Previous permit applications included a withdrawn 2020 proposal for extensive conversions and additions, including new kitchens and bathrooms in multiple units, and a completed 2007 project replacing rear stairs. The building has a history of addressing structural and safety concerns, notably with three separate fire safety violations in 2001 that were promptly abated within the month, and a February 1997 repair of dry rot damage to the rear stairs and deck.

The property has experienced recurring concerns around potentially unauthorized units, with complaints in 1998, 2001, and most recently in 2016 regarding possible illegal units. A significant building complaint was filed in 2007 about unauthorized construction work beyond permitted scope and safety concerns related to a newly built living space. Recent maintenance activities include multiple sidewalk defect reports in June 2024 and various cleaning issues being addressed throughout 2023-2024. The building's past also includes several successful improvements, such as window replacements in 1997, ground floor remodeling, and various repairs documented through building permits. Recent 311 calls have primarily been related to external issues such as sidewalk conditions, street cleaning, and graffiti on the mailbox, rather than internal building concerns. One current open issue from October 2023 involves a pavement defect that remains unresolved.

Risk rating

How 1501 19Th 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.

Neighborhood percentile
49th percentile

Out of 814 buildings in this neighborhood, 415 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 68.0%
Moderate concern 13.2%
Severe concern 18.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
