Initial analysis

The 22-unit, 4-story apartment building at 1440-1450 Washington Street in Nob Hill, owned by Washington Mews LP, was constructed in 1911 and is undergoing significant upgrades to its facilities. Most notably, in 2021-2022, the building completed important safety improvements including fire alarm system upgrades with low-frequency sounders and monitoring radios, representing a $21,000 investment, along with substantial kitchen and bathroom renovations in multiple units (Apts 1, 5, and 3) totaling over $78,000. The property has also achieved its mandatory Soft Story retrofit compliance as a Tier 2 building.

The building's maintenance and upgrade history shows regular attention to both individual units and building-wide systems. Recent improvements include plumbing upgrades in multiple units, electrical system upgrades, and maintenance of essential services like heating. The property has experienced periodic fire alarm system issues (2017-2022) which were all corrected, and there were historically some heating and fire safety violations from 2001-2010 that have since been resolved. In 2023, the building applied for permits to convert the basement into two additional dwelling units, potentially increasing its total to 25 units, though prior attempts for this modification had been withdrawn. While there have been several complaints and 311 calls regarding various services (mostly external to the building), including parking enforcement and street cleaning, these have generally been resolved promptly and do not reflect on the building's internal conditions.

Risk rating

How 1440-1450 Washington 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
8th percentile

Out of 1125 buildings in this neighborhood, 1035 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.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 19.0%
Moderate concern 45.2%
Severe concern 35.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
