Initial analysis

The two-story, four-unit apartment building at 627-629 Hayes Street, owned by Kevin Molinari, has a history dating back to 1900 and has experienced several significant maintenance and safety issues over the years. Most recently, a reroofing project costing $14,000 was completed in August 2024. The building has undergone multiple repairs related to water damage and structural issues, including recurring dry rot problems, particularly in stair structures, with significant repairs documented in 2009 (costing $3,500) and 2005 (costing $8,275). A notable tenant complaint occurred in 2020 regarding unsafe floor conditions with exposed nails and electrical wires following carpet removal in one unit. The building has also experienced weather-related maintenance issues, as evidenced by multiple housing inspections and violations in 2009 related to handrails, weatherproofing, and lead paint hazards.

Historical records show previous safety concerns including a 2006 violation for illegal vehicle repair activities and combustible storage issues, and earlier problems with drainage pipes, window repairs, and heating systems in 2001. The building's maintenance history reveals persistent challenges with stairs and deck structures, as documented through various permits and violations between 1993 and 2009. More recent history shows ongoing concerns with the surrounding street area, as indicated by multiple 311 calls in 2024 regarding garbage, debris, and sanitation issues, though these are external to the building itself. While many past violations and complaints have been resolved, including three carbon monoxide incidents, a 2006 unlicensed auto repair situation, and various fire code violations, the building's history suggests ongoing attention to maintenance issues, particularly regarding moisture-related problems and exterior structures. The most recent building permit activity (2024) shows continued investment in building maintenance, though the age of the building and its reported issues indicate that maintenance will likely remain a recurring requirement.

Risk rating

How 627-629 Hayes 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 1027 buildings in this neighborhood, 811 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 32.8%
Moderate concern 27.2%
Severe concern 40.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
