Initial analysis

The property at 2731-2737 21st Street in the Inner Mission is a two-story, five-unit multi-family residential building with ground-floor commercial space, built in 1905 and currently owned by Mjj Bryant LLC. The building has undergone significant improvements over recent years, with substantial renovation work completed between 2015-2023 including multiple kitchen remodels ($24,000 in 2021, $22,500 in 2020), voluntary ADA access upgrades ($12,500 in 2021), and bathroom renovations. The property experienced several serious maintenance issues in 2015-2016, including reports of mold, electrical problems, plumbing leaks, and various interior surface deficiencies, all of which appear to have been resolved following proper permitting and repairs, though some permits show as expired. The building's systems have been updated significantly, including a water heater replacement in 2023, kitchen and bathroom fixture replacements, and electrical upgrades including a 400-amp service installation in 2004.

Recent history (2022-2024) shows the property has continued to evolve, with the establishment of a small restaurant with limited live performance use in 2022. There have been several 311 calls related to the building's surroundings in 2024, primarily concerning sidewalk cleanliness and graffiti, though these are outside the building's internal maintenance record. The building's previous violations from 2002 regarding security, heating, mold, and general maintenance were all addressed and abated by September 2002. Planning records indicate various approvals for commercial use modifications, including the establishment of limited live performance as an accessory use and restaurant operations, demonstrating ongoing active management and compliance with municipal requirements.

Risk rating

How 2731-2737 21St 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
29th percentile

Out of 2380 buildings in this neighborhood, 1690 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.

Building size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 36.1%
Moderate concern 46.6%
Severe concern 17.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
