Initial analysis

The property at 4165-4167 20th Street is a 3-unit, 2-story multi-family residential building constructed in 1902 and currently owned by Morning Dew Properties LLC. The building has experienced several significant maintenance and safety issues over its history, with the most notable cluster of violations occurring in 2010 when multiple notices were issued and subsequently abated in May 2010. These violations included problems with interior surfaces such as water damage and damaged ceilings, security issues related to self-closing doors, fire safety concerns regarding flammable storage and missing fire extinguishers, and structural problems with handrails and a rear deck. Earlier, in 2009, there was a concerning complaint about an allegedly illegal unit addition, unauthorized construction of back stairs, and general maintenance issues, though this was marked as not active by September 2009.

The building has undergone several permitted improvements over the years, including a significant repair of fire damage in 1984, followed by various renovations including garage conversion attempts (which were ultimately cancelled), horizontal lightwell extension, and interior basement finish work in the mid-1980s. More recent maintenance work was performed in 2009 to address back stairs and deck issues, including railings and loose boards, though this was not directly related to the earlier violations. While there have been numerous 311 calls in the area, particularly regarding parking violations and driveway blockages between 2021 and 2024, these are external issues not directly related to the building's internal conditions. The most recent parking enforcement actions occurred in late 2023, though all were closed as invalid due to incomplete reporting information. The building's violation record, while significant during the 2009-2010 period, shows no active violations since May 2010, suggesting that past issues have been addressed, though the age of the building and its history of various maintenance concerns warrant attention to ongoing upkeep needs.

Risk rating

How 4165-4167 20Th 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 1278 buildings in this neighborhood, 843 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 53.4%
Moderate concern 24.7%
Severe concern 21.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
