Initial analysis

The three-story multi-family residential building at 3826-3830 18th Street, owned by Athanassios Diacakis, has undergone significant renovations and improvements since its construction in 1900. The most substantial recent work occurred in 2017, when both the second and third-floor units received comprehensive renovations including window replacements, complete electrical system upgrades with new main panels, and plumbing improvements including bathroom and kitchen remodels. Prior to that, major structural enhancements were completed in 2013-2014, including the installation of dormers, stairwell additions, and exterior wood siding repairs. The building underwent important safety improvements in 2010, with ground floor strengthening and perimeter anchor bolt installation.

The property has maintained compliance with housing codes since 2002, when several violations related to fire safety and security requirements were promptly addressed and abated by May of that year. While there have been ongoing maintenance issues in the surrounding area - including recent sidewalk collapses (2024), graffiti (2023), and various service requests - the building itself appears to be well-maintained with no active violations or significant internal issues reported. The most recent tenant buyout occurred in 2016, affecting two tenants at 3828 18th Street, with compensation of $75,000. Recent permits indicate continued attention to building maintenance, though there are currently open 311 calls related to sewage discharge (June 2024) that may require follow-up.

Risk rating

How 3826-3830 18Th 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 1278 buildings in this neighborhood, 946 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.

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 47.7%
Moderate concern 16.1%
Severe concern 36.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
