Initial analysis

The three-story, two-unit multi-family residential building at 1815 26th Avenue in San Francisco's Central Sunset neighborhood, owned by Vuong Hang D & Sreewan P, was constructed in 1956 and has undergone several significant modifications over its lifetime, including bathroom and family room alterations in 1985, aluminum window installation in 1986, and multiple roofing projects in 2003 and 2016 costing between $5,470 and $8,500. Of particular concern is an active complaint filed in September 2024 regarding an allegedly illegal basement unit, linked to a recent advertisement on Redfin, which follows a prior similar complaint from July 2024 by a former tenant who vacated an unauthorized ground floor unit. Compliance with building codes has been an ongoing issue, with a permit filed in October 2024 to address electrical and kitchen modification requirements.

The building's history includes some notable incidents affecting resident comfort, such as a water damage issue in 1998 involving leaks from multiple locations and electrical problems, though this was resolved within several months. Recent activity around the property has generated multiple 311 calls primarily related to external concerns rather than building-specific issues, including parking violations (sidewalk parking, blocked driveways), noise complaints (barking dogs), and reports of sidewalk encampments. While most of these external issues were resolved by city services, they indicate some neighborhood challenges in the immediate vicinity. The building's maintenance record shows regular upkeep through permitted improvements, though the recent violations regarding unauthorized units suggest ongoing compliance challenges that have persisted for decades.

Risk rating

How 1815 26Th 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

Out of 814 buildings in this neighborhood, 505 are predicted to be safer.
