Initial analysis

The property at 3818 26th Street in Noe Valley is a two-unit, two-story duplex built in 1910 and owned by Miguel A. Sesana. The building's permit history shows a vinyl siding and window installation project from 1995, though this permit has since expired. More concerning are the building complaints from April 1999, which documented several maintenance issues including water damage in the sun room affecting ceilings and floors, an inoperative door lock presenting a security hazard, absence of a smoke detector, a malfunctioning and odorous furnace, as well as roof leaks and problems with multiple doors. While these complaints were officially marked as "Not Active" by August 1999, they indicate a period of significant maintenance challenges.

The property's more recent history, from 2020 through 2024, has primarily involved external issues rather than internal building problems. These include multiple instances of parking violations (most recently in July 2024 and September 2022), various sanitation issues such as garbage and debris complaints (including one involving medical waste) in 2024, and several general maintenance matters like tree root damage to sewer infrastructure reported in October 2021, which remains open. The frequency of parking-related incidents and sanitation issues in the immediate vicinity suggests ongoing external challenges, though none of these recent issues directly pertains to the building's internal conditions or structural integrity.

Risk rating

How 3818 26Th 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 1879 buildings in this neighborhood, 338 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

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.

12-Month severity forecast
No violation 82.0%
Moderate concern 10.6%
Severe concern 7.4%
