Initial analysis

This two-unit, two-story multi-family residential building located at 2912-2914 21st Street in the Inner Mission was built in 1900 and is currently owned by Virginia Lopez. The property has experienced several significant maintenance and repair events, most notably a serious fire incident in October 2010 that rendered the building unsafe and required extensive repairs, including electrical rewiring, plumbing work, and structure rehabilitation. The fire damage repairs, completed in 2011, involved comprehensive work including kitchen remodeling, bathroom additions, and infrastructure improvements costing approximately $38,000.

More recently, in September 2023, the building experienced a serious plumbing incident involving toilet overflow from an upstairs unit that affected the lower unit's pantry and kitchen areas, raising concerns about sanitation and safety. This incident appears to be related to recurring water damage issues, as evidenced by maintenance history including sheetrock replacement due to water damage in 2011. The building's maintenance record shows previous concerns in 1997-1998 regarding garbage accumulation, illegal rooms, and safety features, though these were reportedly resolved at that time. The property has also required various plumbing and electrical updates over the years, including heating system replacement in 2011 and comprehensive system checks for both units. Recent 311 calls (from 2021 to 2025) indicate ongoing challenges with waste management and parking enforcement in the vicinity of the building, though these are external to the building's structure and systems.

Risk rating

How 2912-2914 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
67th percentile

Out of 2380 buildings in this neighborhood, 785 are predicted to be safer.

Model explanation

What's driving this score

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

Severe concern 7.7%
