Initial analysis

The two-unit residential building at 281 30th Street in Glen Park is a 2-story flats and duplex structure built in 1907, currently owned by Patrick D Mahoney Sprte Sha. The building's most significant historical maintenance record shows multiple violations in March 2002, when Housing Inspection Services documented numerous issues including mold and mildew problems, window malfunctions, heating system deficiencies, stair repairs needed, and bathroom ventilation concerns. All these violations were subsequently abated by May 1, 2002. A reroofing project was completed in May 2004 at a cost of $6,500. More recently, in 2010, there was a fire alarm system issue that was promptly resolved on the same day of reporting.

The property has undergone several infrastructure inspections and repairs in the surrounding area between 2016-2024, with recent concerns primarily related to pavement defects and sidewalk conditions. There are currently two active pavement defect cases from July 2024, and while the building itself has not had major violations or complaints in recent years, there have been multiple street-level maintenance and service requests in the vicinity, including responses to waste management issues, cleaning needs, and various infrastructure repairs. The most recent building-specific issues to note are the two pending pavement defect reports from July 2024, though these concern public infrastructure rather than the building itself.

Risk rating

How 281 30Th 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
80th percentile

Out of 364 buildings in this neighborhood, 73 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.

Building age

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 85.2%
Moderate concern 10.3%
Severe concern 4.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
