Initial analysis

The property at 1042-1048 Montgomery Street is a two-story, 5-unit multi-family residential building located in Telegraph Hill, built in 1906 and currently owned by the Mitchell Wong Revocable Trust 2012. The building has undergone significant seismic safety improvements, completing a mandatory Tier 3 Soft Story Retrofit in 2020 at a cost of $70,000, following multiple prior permit applications and violations related to non-compliance with the San Francisco Building Code earthquake safety requirements. The most recent proposed improvement, filed in December 2022, seeks to convert an 830 sq. ft. storage area into a 1-bedroom ADU with associated bathroom and kitchen modifications, though this permit is still in "Filed" status.

The building's history includes several notable events, including a 2014 Notice of Violation related to unauthorized construction changes, including incorrect door and window installations, though these issues were resolved by November 2015 through the issuance of the appropriate permits and completion of required modifications. In 2015, the property underwent corrections to address various safety concerns, including fire safety violations such as the need for fire extinguisher recharges and the installation of smoke detectors. More recently, there was a complaint in June 2020 regarding unannounced utility shut-offs during construction work, though this complaint is now inactive. The most recent service-related issues include a flooding incident reported in February 2024 that was promptly addressed by PUC Sewer Operations. The building has maintained regular compliance with various safety and maintenance requirements over the years, with most historical violations having been resolved through appropriate corrective actions and permits.

Risk rating

How 1042-1048 Montgomery 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

Out of 684 buildings in this neighborhood, 581 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.

DBI tenant complaints (past 7 years)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 44.8%
Moderate concern 35.4%
Severe concern 19.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
