Initial analysis

The 4-unit, 2-story multi-family residential building at 31 Landers Street in Mission Dolores, owned by the Yuen Betty Revocable Trust, was built in 1927 and has undergone several significant renovations and faced various compliance issues over the years. The most recent major renovations include ongoing interior remodeling of the first floor to create a family room with wet bar and exercise area (approved in July 2024), along with interior rewiring and bathroom/kitchen updates scheduled for completion by late 2024. The building's maintenance history shows regular upkeep, including reroofing projects in 2008 and 2014, and stair repairs completed in 2005.

The property has experienced notable compliance challenges, particularly between 2005 and 2013, including multiple violations related to fire safety, window installation without permits, and building maintenance issues. These violations, all of which have been abated, encompassed concerns about stairs, lead paint hazards, interior surface repairs, and a fire alarm maintenance issue documented in February 2006. More recent history includes a complaint in June 2024 regarding construction work hours and potential permit violations, though this was marked as not active shortly thereafter. The building has undergone routine housing inspections in 1999 and 2003, with the latter noting hallway lighting issues that were promptly addressed.

Risk rating

How 31 Landers 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

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.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

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 59.7%
Moderate concern 22.2%
Severe concern 18.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
