Initial analysis

The two-story, four-unit multi-family residential building at 118-120 20th Avenue, owned by Heidy & Norbert Lee, was constructed in 1913 and has experienced several significant events throughout its history. Most recently, in 2022, there was a plumbing issue reported in May that took some time to address, and earlier that same year, multiple tree-related incidents occurred in March. The building has undergone several major repairs and modifications, including re-roofing in 2014 (cost: $15,800), staircase repairs in 2006, and kitchen renovations in 2001 (cost: $9,250). A significant compliance issue arose in 2007 when it was reported that a room in Unit #118 had been illegally converted into a guest room with cooking facilities, violating the building's special restrictions. This led to the removal of unauthorized kitchenette equipment and plumbing in 2009.

The building has faced various safety and maintenance challenges, particularly in the early 2000s, when it received multiple fire safety violations that required resolution, including issues with combustible storage, fire proofing materials, fire extinguishers, smoke detectors, and garbage receptacle placement. A notable incident occurred in 2002 regarding a modified fire escape that was obstructed by a satellite dish. More recent routine inspections have generally been resolved without major findings, though there was a broken window reported in 2009 and another plumbing issue in 2022. The property has maintained regular compliance with building codes since the mid-1980s, when it underwent a significant compliance upgrade in 1985 (cost: $3,000). While there have been occasional issues with parking and tree maintenance in the surrounding area, these are external to the building itself and have been handled by appropriate city departments.

Risk rating

How 118-120 20Th Ave'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
11th percentile

Out of 660 buildings in this neighborhood, 587 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 44.0%
Moderate concern 43.5%
Severe concern 12.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
