Initial analysis

The 4-unit, 4-story apartment building at 1509 Taraval Street in the Parkside neighborhood was constructed in 2006 and is currently owned by John Y C & Eva L Tang Living Trust. The property has experienced significant ongoing maintenance and safety issues throughout 2023, with active violations as of January 2023 related to water damage, including wet carpeting, water-damaged walls and ceilings, missing floor coverings, and flexible ducting concerns. A notable building safety issue was addressed in February 2023 when a section of fire-rated ceiling was repaired in the garage at a cost of $10,000, following a complaint from January 2023. The building has a history of plumbing challenges, with multiple sewer-related incidents reported in 2024, including a sewage backup discharge and odor issues from the side sewer vent. Construction and safety features were installed during the building's initial development, including fire sprinklers throughout (2005) and an electrical system consisting of multiple lights, switches, receptacles, and panels (2005). The property has undergone various maintenance activities over the years, including a re-roofing project in 2017 costing $14,500. Recent complaints also indicate issues with flooding, window seals, and mold, with the building's maintenance response being scrutinized by residents.

The building's construction history includes attempts to add three additional residential units to a commercial space, though these proposals were ultimately disapproved. A Cottage Food Operator permit has been approved for the property, allowing a non-formula retail use as an accessory function. Recent 311 calls from 2024 have primarily concerned street cleaning and sanitation issues, including reports of debris, garbage, and parking violations near the property. While the building underwent thorough initial construction and safety installations in the early 2000s, recent years have seen recurring issues primarily related to water damage, plumbing, and building maintenance requiring ongoing attention.

Risk rating

How 1509 Taraval 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

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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Number of units

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

12-Month severity forecast
No violation 18.1%
Moderate concern 43.1%
Severe concern 38.8%
