Initial analysis

The 16-unit, 2-story multi-family residential building at 1637 15th Street in the Inner Mission, built in 1925 and owned by Mission Housing Development Corp, has undergone significant infrastructure improvements and faced recurring maintenance challenges over recent years. The property completed mandatory seismic retrofitting in 2017 as a Tier 2 soft-story building, along with major updates to its fire safety systems including a new fire alarm system and smoke detector installations in 2018. Significant plumbing and mechanical work was performed between 2017-2018, including boiler replacement, sewer repairs, and roofing projects totaling over $600,000.

However, the building has experienced persistent issues with heating and hot water systems, with multiple tenant complaints about inadequate heat in 2019, 2022, and most recently in January 2025, as well as water supply problems documented in 2024. The building's maintenance record shows several violations related to heating, door security, and fire safety systems in 2018, though most were abated by July 2018. Recent fire violations from December 2023 concerning sleeping area requirements and a 2022 violation regarding fire extinguishers remain of particular concern. The property has also maintained active plumbing infrastructure with repairs and updates continuing through 2023, including work on gas lines and sewer systems. Recent 311 calls from 2024 indicate ongoing issues with garbage management around the property, though these are more related to exterior maintenance than building systems.

Risk rating

How 1637 15Th 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
4th percentile

Out of 2380 buildings in this neighborhood, 2285 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

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.

12-Month severity forecast
No violation 10.1%
Moderate concern 53.7%
Severe concern 36.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
