Initial analysis

The three-unit TIC building at 4644-4648 18th Street, owned by Robert Devor, has undergone several significant renovations and faced multiple maintenance challenges since its construction in 1900. The most recent improvement was completed in 2023 with the installation of a new 240V 50AMP circuit for an electric vehicle charging station in the garage, demonstrating ongoing modernization efforts. In 2013, a waterproof front landing was added, while in 2008 substantial renovations were completed including kitchen cabinet replacements, bathroom fixture updates, and front porch improvements. The building has a documented history of serious maintenance issues that were addressed, particularly in 2007-2008 when there were multiple violations and repair needs including safety concerns with guardrails, fire safety violations, and interior surface problems. These issues, which included weatherproofing, gas utility requirements, and lead paint concerns, were ultimately abated by September 2008.

Earlier maintenance records from 2000 show some basic infrastructure work and compliance matters, while more recent 311 calls in the parking lot area in 2018 and 2022 recorded minor issues related to pavement defects and street cleaning. A sewage backup incident was reported and resolved in 2012, though this appears to be an isolated event. The building's electrical and plumbing systems have seen periodic upgrades, with several permits showing infrastructure improvements, though some permits from 2007 were cancelled or expired rather than completed. The property's maintenance history suggests a pattern of addressing both routine and urgent repairs over time, with particular attention paid to safety concerns when they arise.

Risk rating

How 4644-4648 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, 690 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.

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 68.6%
Moderate concern 21.9%
Severe concern 9.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
