Initial analysis

The property at 1201-1207 46th Avenue in San Francisco's Outer Sunset neighborhood is a two-story, four-unit multi-family residential building constructed in 1911 and currently owned by James William Mustanich Jr. The building has experienced several significant maintenance and compliance issues over the past decade. Most notably, there are eight active building violations from March 2010 related to water damage, mold/mildew, lead paint concerns, and stair safety issues, though some of these appear to have been addressed through subsequent repairs and renovations. In 2021, the rear stairs were partially repaired with new support posts and floor joists, and the building underwent plumbing improvements with a new sewer lateral installation. A complaint regarding unpermitted roof work was filed in August 2023 but was quickly resolved the following day.

The property has a documented history of water-related issues, including mold problems that triggered multiple complaints in 2010, plumbing repairs, and a significant sewer-related complaint from 1996. Several renovation projects were completed in 2010 to address various problems, including bathroom and kitchen improvements, lead paint concerns, and mold remediation. Unit 1203 received specific electrical and sheetrock upgrades in 2008. More recently, between late 2023 and early 2024, there have been multiple reports of garbage and debris issues, including furniture, though these relate to street cleaning rather than building conditions. While some past issues suggest historical maintenance challenges, most recent permits (2021) indicate regular upkeep, albeit with some recurring maintenance patterns. The building's history shows a mix of proactive repairs and occasional reactive responses to violations, with most housing-related complaints being resolved through proper permits and remediation work.

Risk rating

How 1201-1207 46Th 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
25th percentile

Out of 632 buildings in this neighborhood, 474 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 32.7%
Moderate concern 28.5%
Severe concern 38.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
