Initial analysis

The three-story, six-unit multi-family residential building at 144-148 Grattan Street, located in the Parnassus/Ashbury Heights neighborhood, was constructed in 1909 and has experienced several significant maintenance events over its lifetime. The most pressing current issue is a pattern of garbage and debris overflow, with ten resolved cases documented between September 2024 and December 2024, indicating ongoing challenges with waste management in the area. The building previously underwent notable repairs in 2001-2002, including the replacement of dry rot sections in the rear stairs and addressing multiple violations related to safety and maintenance, such as guardrails, handrails, electrical outlets, and egress clearance. These violations, part of two complaints filed in late 2001, were officially abated by May 2002.

Historical maintenance work includes a street space permit in 2019, gas line extension work in 2013, stair lighting installation in 2003, and a reroofing project completed in 1993. The building has undergone various inspections and permit requirements over the years, including sidewalk repairs in 2002 and multiple permit revisions related to stair repairs in 2001, with some permits showing as expired. While the major violations from 2001-2002 were resolved, the recent pattern of waste management issues suggests ongoing maintenance challenges in the vicinity.

Risk rating

How 144-148 Grattan 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
24th percentile

Out of 526 buildings in this neighborhood, 400 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.

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 56.6%
Moderate concern 20.6%
Severe concern 22.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
