Initial analysis

The property at 18-20 Valletta Court in Glen Park is a 2-unit, 2-story multi-family residential building constructed in 1977, currently owned by Lum Tr. The building has undergone several significant improvements over the years, most notably the installation of solar panels in 2013, with multiple permits showing the installation of 12, 16, and 14 roof-mounted solar PV modules at different times throughout the year. The property has seen consistent maintenance and improvements, including reroofing work completed in 2019 at a cost of $6,800, deck repairs in 2011, and substantial basement improvements in 2004 that added a bedroom, playroom, full bathroom, and a rear deck. Electrical work was completed in 2005 to support these basement modifications, including the installation of lights, switches, receptacles, and a sub-panel.

The building's history includes some notable incidents that required attention, including complaints about hazardous stairs and a possible illegal in-law unit in 2006, though both issues were promptly addressed and marked as "Not Active." In terms of recent infrastructure and environmental improvements, the property has been proactive in adopting renewable energy technology with the installation of multiple solar panel systems in 2013. The building's maintenance record shows regular upkeep, including multiple roofing projects and deck repairs. Recent 311 calls related to the property have primarily concerned external issues such as street parking, tree maintenance, and sewer concerns, which appear to have been resolved promptly and are not directly related to the building's structural or safety systems.

Risk rating

How 18-20 Valletta Ct'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
56th percentile

Out of 364 buildings in this neighborhood, 160 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 82.8%
Moderate concern 10.5%
Severe concern 6.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
