Initial analysis

The property at 4131-4133 Clement Street is a three-story, two-unit multi-family residential building constructed in 1946 in San Francisco's Outer Richmond neighborhood. The building underwent significant renovations in 2014, with major work including the construction of a new ground floor bathroom, bedroom, family room, and laundry area, as well as the installation of a comprehensive NFPA 13-R sprinkler system with 50 sprinklers. This renovation, valued at $126,000, was accompanied by window replacements, mechanical upgrades, and electrical improvements throughout the building. The sprinkler system installation was particularly noteworthy for its safety enhancements, though there were some construction complaints from nearby residents in June 2014 regarding potentially unauthorized work on a downstairs unit, which were subsequently marked as "Not Active."

More recent improvements include the installation of radiant heating systems for both units in 2016, indicating ongoing modernization efforts. The building's mechanical systems received substantial updates during the 2014 renovations, including new water heaters, plumbing infrastructure, and extensive electrical upgrades servicing multiple kitchens, bathrooms, and living areas. The property has experienced numerous 311 calls since 2016, primarily related to parking issues, though these are generally not indicative of internal building conditions. Several calls in 2019-2020 related to illegal parking and sidewalk issues were resolved through enforcement actions. A 2022 parking violation resulted in a citation being issued. While there have been various maintenance-related service requests between 2016 and 2022, including reports of hazardous materials and general street cleaning needs, these appear to be more related to external conditions rather than building-specific issues.

Risk rating

How 4131-4133 Clement 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 1040 buildings in this neighborhood, 114 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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 84.7%
Moderate concern 12.2%
Severe concern 3.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
