Initial analysis

The two-unit multi-family residential building at 3975 Cesar Chavez St in Noe Valley, owned by Christian Keller Revocable Trust, has undergone significant renovations and infrastructure improvements over recent years. Built in 1900, this two-story flats and duplex structure has seen substantial work since 2022, including a major $554,000 renovation in late 2022 involving foundation replacement, window upgrades, door replacements, and deck modifications. Of particular note is the ongoing installation of a fire sprinkler system, with permits issued in 2024 showing the implementation of NFPA 13D and 24 systems, suggesting improved safety features being added to the building. The property has also experienced recent HVAC upgrades, with permits showing the installation of multiple mini-split systems and forced air systems throughout the building in mid-2024.

The building's history includes some concerning safety issues, most notably an active complaint from 2001 regarding collapsed rear stairs and an unpermitted deck construction issue. However, substantial efforts have been made to improve the building's infrastructure, including a significant electrical upgrade underway as of December 2024, doubling the service capacity from 200 amps to 400 amps. Recent plumbing work has focused on comprehensive remodeling of two kitchens, three and a half bathrooms, and related infrastructure improvements. While there have been several parking-related complaints in the area and some issues with waste receptacles, these are generally routine neighborhood concerns and not specific to the building's condition. The extensive permit history, particularly in recent years, demonstrates ongoing investment in the property's maintenance and safety systems, with most recent permits focusing on fire safety and climate control improvements.

Risk rating

How 3975 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
95th percentile

Out of 1879 buildings in this neighborhood, 94 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.

Building age

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

Neighborhood location

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

Property class: single-family home

Single-family homes (class A) have distinct violation and complaint patterns from multi-family buildings.

12-Month severity forecast
No violation 89.6%
Moderate concern 8.6%
Severe concern 1.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
