Initial analysis

The 15-unit, three-story multi-family residential building at 1635 Jones Street in Nob Hill, managed by Csl Management Co LLC, has undergone several significant improvements and faced various challenges since its construction in 1928. Most notably, the building completed mandatory soft-story seismic upgrades in 2017 under Tier 2 requirements, and a more recent fire alarm system upgrade was completed in 2022 to comply with San Francisco Fire Code requirements, including installation of low-frequency sounders in sleeping areas. The building has a history of maintenance and compliance issues, with several complaints and violations recorded between 2000 and 2018, primarily related to fire safety, egress, and general maintenance. These included concerns about combustible storage, fire escape maintenance, and window replacements, though most violations were eventually abated. Recent years have shown a pattern of plumbing and building system upgrades, including the installation of washing machine facilities in 2020, and previous replacements of water heaters and the steam boiler. The property has undergone routine inspections, including several investigations of maintenance issues and tenant complaints between 2015 and 2024, with the most recent common areas complaint filed and resolved in March 2024. While most safety-related issues appear to have been addressed through various permits and corrections, recent 311 calls (2024-2025) show ongoing concerns with street-level garbage and debris management near the property, though these are external to the building itself and seem to occur regularly in the area.

Risk rating

How 1635 Jones 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

Out of 1125 buildings in this neighborhood, 1012 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.

Building size

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

Neighborhood location

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

12-Month severity forecast
No violation 15.3%
Moderate concern 70.9%
Severe concern 13.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
