Initial analysis

The 15-unit apartment building at 1247 11th Avenue in the Inner Sunset, owned by 11th Avenue Apts LP, is a three-story multi-family residential structure built in 1965. The property has undergone significant safety and infrastructure improvements over the past several decades, with the most recent work in 2024 involving window replacements and new siding installation costing $48,000. Notable completed projects include a comprehensive fire alarm system upgrade in 2019 to meet current codes, a mandatory soft-story retrofit in 2016, and seismic improvements to the carport in 1998, demonstrating compliance with safety regulations. Maintenance issues have been addressed over time, including dry-rot repairs in 2010 and plumbing updates in 2019.

Currently, there is an active tenant complaint from January 2025 regarding heating system issues ("Heat can't turn off"), which has yet to be resolved. The building experienced multiple fire safety inspections in recent years, with most issues being promptly addressed or deemed to have "No Merit," though there was one instance in 2022 regarding alarm systems that required correction. A pattern of driveway blocking violations has emerged recently, with multiple citations issued between November 2024 and January 2025, though these are parking enforcement matters unrelated to building safety.

Risk rating

How 1247 11Th Ave'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 1493 buildings in this neighborhood, 1433 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 10.6%
Moderate concern 19.6%
Severe concern 69.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
