Initial analysis

The three-unit multi-family residential building at 135 18th Avenue, owned by the Low Gene K & Hannah S Trust, has a documented history spanning over two decades, with the most recent significant event being a comprehensive re-roofing project completed in October 2024 costing $30,000. The property experienced a notable fire incident in October 2021 that required repairs to two floor joints and subfloor work in Unit A, along with subsequent upgrades to the unit's systems including a new furnace installation, gas line addition, and electrical subpanel upgrade. The building's electrical infrastructure has seen improvements over the years, with a major upgrade from 100 to 200 amp service completed in 2005.

Of particular concern is the recent pattern of sewage-related issues, with multiple incidents reported through 311 calls in late 2024, suggesting ongoing plumbing system challenges. The property's maintenance history includes various works such as street space usage (2020), and a complaint in 2001 regarding unpermitted remodeling was filed and subsequently abated. The building's exterior envelope has required attention over time, as demonstrated by the recent re-roofing work, which replaced existing materials in-kind. The property has experienced some structural and accessibility issues, including a 2024 report of a difficult-to-open restroom door following renovations, though this was subsequently addressed according to records.

Risk rating

How 135 18Th Ave'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
40th percentile

Out of 660 buildings in this neighborhood, 396 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.

Estimated permit spend (past 7 years)

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

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 73.5%
Moderate concern 20.0%
Severe concern 6.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
