Initial analysis

The two-unit residential building at 3171-3173 Cesar Chavez Street in Bernal Heights, owned by Cheng Chun-chih, was constructed in 1911 and is classified as a two-story flats and duplex structure. The property has undergone several significant maintenance and improvement projects over the past decade, including a complete sewer line replacement in 2015, re-roofing work in 2022 costing $6,000, and a filed proposal in 2021 for an ADU addition that includes demolishing exterior stairs, building a new balcony, and adding a wet bar. Historical records indicate a building complaint was filed in 1996 regarding welding work, overcrowding, and concerns about an illegal apartment, though this was resolved within weeks. The building has experienced various fire-related incidents, including two gas leak responses and three other good intent calls by emergency services, none of which resulted in civilian injuries.

The property has been the subject of multiple tenant buyouts in March 2019, with three separate transactions totaling $169,500 across 15 tenants (7 from 3173 units, 5 from 3171 units, and 3 from 3171 units). A conditional use authorization request to remove an illegal dwelling unit was withdrawn in 2019, though there have been multiple planning records related to an illegal unit investigation. The surrounding area has seen frequent recent activity, particularly in 2024, with numerous parking-related complaints and resolved encampment situations, though these are external to the building itself. A cancelled roofing permit was filed in 2018, and earlier records from 1985 show an expired permit for stair repairs, indicating ongoing structural maintenance concerns have been addressed over time.

Risk rating

How 3171-3173 Cesar Chavez 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.

Neighborhood location

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

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 89.1%
Moderate concern 8.7%
Severe concern 2.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
