Initial analysis

The three-story, 10-unit multi-family residential building at 1045-1059 Broadway in Nob Hill, owned by Mosser Annabelle I, was constructed in 1908 and has undergone several significant renovations over the past decade. Most notably, there have been recurring fire safety concerns, with the most recent fire alarm system upgrade filed in July 2023 (and previously attempted in 2023), and multiple sprinkler/standpipe system violations documented between 2017 and 2024. The building has seen substantial interior improvements between 2014 and 2019, including multiple kitchen and bathroom renovations in various units, with documented expenditures ranging from $7,000 to $30,300, along with associated electrical and plumbing upgrades.

The property has a history of fire safety violations that require attention, including a 2024 violation for alarm system maintenance and 2023 violation for sprinkler service. While the building underwent routine inspections in 2000, 2008, and 2016, and had several housing violation cases between 2000-2008, all of these were ultimately resolved. More recent complaints and service calls from late 2024 have primarily concerned street cleaning and graffiti issues near the property, rather than internal building concerns. While the building has demonstrated ongoing investment in upgrades and maintenance, particularly related to unit improvements and safety systems, the recurring nature of fire safety violations suggests this remains an area requiring continuous attention and compliance efforts.

Risk rating

How 1045-1059 Broadway'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 1125 buildings in this neighborhood, 934 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 13.4%
Moderate concern 45.9%
Severe concern 40.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
