Initial analysis

The property at 3503-3505 23rd Street is a three-story, two-unit multi-family residential building located in Noe Valley, built in 1900 and currently owned by Sunbeam Arts LLC. The building has undergone several significant improvements over the past decade, with the most recent major work occurring in 2022 involving fire-safe sheetrock replacement at both unit entrances. A substantial renovation was completed in 2015, including kitchen and bathroom remodels, heating system upgrades, and extensive electrical work, though there are concerns due to an active complaint filed in January 2021 regarding unauthorized work attempting to combine the two units. Other notable improvements include a roof replacement in 2008 (cost: $17,000), stair repairs in 2008, and foundation work in 2004.

Recent maintenance issues have primarily related to exterior conditions, with multiple 311 calls between December 2024 and January 2025 reporting various types of debris and waste on the property, though these were primarily street-related issues. A sewer odor complaint remains open from December 2024. While there was a 2020 permit filed for a 200-amp electrical panel upgrade, this was cancelled. The property has maintained its two-unit configuration despite the 2021 complaint, and while there have been several permits issued for street space use, these appear to be routine. The building is located in a California Register-eligible district, and there was a planning inquiry regarding potential attic and dormer space addition, though this was marked as informational without a developer attached.

Risk rating

How 3503-3505 23Rd 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.
