Initial analysis

The property at 747-749 Capp Street is a two-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and classified as a Flats & Duplex structure. The building has undergone several significant modifications and improvements over the years, with the most recent major issue being a pending investigation into an unauthorized dwelling unit that was reported as a neighborhood concern in April 2019 and is currently under review. This situation has historical context, as the owner initiated legalization efforts in 2017 under the ADU ordinance, and there was a previous complaint in 2016 regarding possible short-term rental activity. Other notable improvements include a completed solar panel installation in 2003 (both electrical and roofing work), a completed sewer line replacement in 2014, and various renovations in the late 1980s and early 1990s, including kitchen and bathroom remodels, plumbing and electrical upgrades, and restoration of original ceiling height. The building has experienced some infrastructure issues, including a sewage backup incident in 2013, and there have been multiple 311 calls regarding street cleaning matters in 2016. Recent records from 2024 indicate issues with human waste on the property and driveway blocking incidents, though these are primarily external concerns not directly related to the building's condition. The property's maintenance history shows attention to systems upgrades and compliance issues, with most permits having been successfully completed or resolved, though some older permits from the 1990s are listed as expired or cancelled.

Risk rating

How 747-749 Capp 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 2380 buildings in this neighborhood, 571 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 (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

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 67.2%
Moderate concern 16.8%
Severe concern 16.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
