Initial analysis

The property at 1459-1461 17th Ave is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, owned by the James & Winnis Chiang Living Trust. Built in 1925, this flats/duplex building has undergone significant recent improvements, particularly in 2022 when both units received substantial renovations. Unit 1459 received window replacements and Unit 1461 underwent a comprehensive renovation including bathroom and kitchen updates, conversion of an office into bathrooms, and window replacements with improved energy efficiency ratings. Both units benefited from complete rewiring with new electrical systems, including sub-panels and numerous outlets, as well as plumbing upgrades featuring modern amenities like tankless water heaters and radiant heat systems.

The building's recent history shows major infrastructure improvements including a 200-amp electrical service upgrade in 2016 and extensive renovations in 2021-2022 totaling over $135,000 in permitted work. Previous issues from 2003 regarding inadequate smoke detection systems were promptly addressed and resolved by January 2004, following a housing inspection complaint. Historical records indicate earlier renovations including reroofing work in 2004 and window installations in 1985. While there was a 311 call in June 2023 regarding a parking issue, this was unrelated to building conditions and was promptly handled by parking enforcement.

Risk rating

How 1459-1461 17Th 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
98th percentile

Out of 1493 buildings in this neighborhood, 30 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.

Neighborhood location

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.

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 91.8%
Moderate concern 6.2%
Severe concern 1.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
