Initial analysis

The two-unit residential building at 132-134 Blake Street in Lone Mountain is a two-story flats and duplex structure owned by the Mary R Coulton Revocable Trust and built in 1900. The property has undergone several significant improvements over the past decade, with the most substantial recent work occurring in 2021, involving the replacement of the ground floor slab, footings, posts, and the addition of new insulation and gypsum board, at a cost of $20,000. Other notable permitted work includes a complete roof replacement in 2010 ($9,200) and sewer line and house trap replacement in 2012. A concerning issue was documented in 2006 regarding an illegal basement unit lacking proper amenities, though this complaint was promptly investigated and marked as not active.

The property has been subject to frequent parking-related complaints in recent years, with multiple instances of blocked driveways and illegal parking documented between 2023-2024, resulting in several citations. While these parking issues may impact resident convenience, they do not directly affect building safety or habitability. Additionally, there was one hazardous materials incident reported in June 2023 involving liquid substances, though this was marked as resolved. The building received regulatory attention in 1993 for violations that were subsequently corrected. The property's maintenance history suggests regular upkeep, with major systems like roofing and plumbing having been updated or replaced as needed, though it's worth noting that the 2021 ground floor work indicates ongoing maintenance of the building's structural components.

Risk rating

How 132-134 Blake 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
82th percentile

Out of 519 buildings in this neighborhood, 93 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.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Estimated permit spend (past 7 years)

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

12-Month severity forecast
No violation 87.5%
Moderate concern 9.3%
Severe concern 3.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
