Initial analysis

The property at 3823-3825 18th Street is a 2-story, 4-unit multi-family residential building constructed in 1902, currently owned by Sebastian & Ramona Alexandr. The building underwent significant renovations in late 2011, including a major $20,000 kitchen remodel in unit #4, removal of masonry flues in units #2 and #4, and electrical work including new lighting installations. A notable revision in early 2012 resulted in the relocation of laundry facilities into a fire-rated enclosure in a common area, which was completed with associated electrical and plumbing upgrades. The building has been generally well-maintained since, with more recent work including repair and repainting of front stairs in 2017 ($2,000).

Historical records show some concerning issues from the early 2000s, including multiple violations in 2002 related to stair repairs, fire safety, and gas utility requirements, though all were abated by April 2002. A 2003 complaint about unauthorized construction of dormers and windows was resolved by 2011. Recent 311 calls from 2022-2024 primarily relate to external maintenance issues such as graffiti and sidewalk cleaning, with the most recent being a graffiti complaint from December 2024. The building's location has experienced periodic issues with urban challenges like encampments and waste on nearby sidewalks, particularly noted in 2022 and 2024 reports, though these are external to the building itself. The property appears to be regularly maintained, with recent complaints typically being addressed promptly through city services.

Risk rating

How 3823-3825 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.
