Initial analysis

The property at 43-45 Surrey Street in Glen Park is a one-story, multi-family residential building (duplex) owned by Nina Mulderrig, dating back to 1910. The building has undergone several significant improvements over the past two decades, with the most recent work completed in 2023 involving an extensive $15,000 renovation of the back of the home including siding replacement, window waterproofing, and new insulation installation. In 2005, a substantial bathroom and deck addition project valued at $60,000 was completed, followed by electrical upgrades in 2006 including wiring for two bathrooms and installation of a new 200-amp service. The building's electrical system has seen proper maintenance, with records showing changes from overhead to underground service, though some earlier service permits expired without completion.

Recent 311 calls from 2020 to 2024 primarily relate to street and sidewalk maintenance issues, including missed trash collections, garbage debris, and curb defects, though these are external to the building itself. There have been some parking-related complaints in 2019-2021, and a hazardous materials incident involving glass on the street in 2019. The property appears to be well-maintained in terms of major systems, with no recorded building code violations or safety concerns. The most pressing recent issues have been related to street services and parking, which are municipal rather than building management concerns. The completion of the 2023 siding and insulation work suggests ongoing maintenance and upkeep of the property by the current owner.

Risk rating

How 43-45 Surrey 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
57th percentile

Out of 364 buildings in this neighborhood, 157 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

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 81.9%
Moderate concern 13.9%
Severe concern 4.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
