Initial analysis

The property at 341-343 Lexington Street, a two-story multi-family residential building constructed in 1900, consists of four units and is currently owned by Peter Dana Porras. Recent significant improvements include substantial electrical upgrades in early 2024, with new wiring, removal of knob and tube systems, and installation of new sub-panels throughout all units. Plumbing infrastructure has been significantly updated, with permits issued in March 2024 for extensive work including kitchen and laundry facilities, and the removal of inactive water supply lines. The building has undergone several important structural and safety improvements in recent years, including insulation work in early 2024, voluntary structural strengthening in 2022, and a complete roof replacement in 2014.

The building's history reveals some concerning patterns of maintenance issues and code violations, particularly in the early 2000s. A cluster of violations was documented in late 2003, including problems with stairs, handrails, fire safety systems, and plumbing, though these were all abated by May 2004. More recent complaints in 2014 and 2023 regarding unpermitted work and code compliance issues were also resolved. Of particular note are two complaints from 2015 concerning missing smoke alarms and various unit maintenance issues, which were addressed and closed. The property has maintained regular maintenance patterns in recent years, with multiple substantial improvements made to address older building systems. While some 311 calls regarding the property have been logged, mostly relating to street cleaning and maintenance matters, these do not appear to reflect significant building-specific issues.

Risk rating

How 341-343 Lexington 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
39th percentile

Out of 2380 buildings in this neighborhood, 1452 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building 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 41.0%
Moderate concern 32.9%
Severe concern 26.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
