Initial analysis

The property at 3508 23rd Street in Noe Valley is a two-story, multi-family residential building constructed in 1890, currently owned by Micah Hawes-Sivitz and Veera. The building has undergone significant improvements and renovations in recent years, with the most substantial work occurring between 2020 and 2022. Major projects included the addition of an ADU (Accessory Dwelling Unit) on the first floor with two bedrooms and two bathrooms (completed in 2020), a full seismic upgrade and remodeling of the two existing units (2020), and comprehensive safety improvements including the installation of 21 fire sprinklers throughout the ground floor (2021) and a new sprinkler monitoring system (2022). The building's infrastructure has been modernized with new plumbing systems installed for five bathrooms, two kitchens, and two laundry facilities, along with the addition of condensing boilers with radiant heating (2020).

The property has maintained a positive maintenance record with no fire incidents reported except for one false smoke detector activation. Historical records show earlier repairs including reroofing work in 2003 and repairs to an exterior rear staircase in 2000. Recent 311 calls have primarily been related to street and sidewalk maintenance issues, including reports of loose garbage, a blocked sidewalk due to a mobile storage container, and some cleaned up graffiti. The building's improvements appear to have focused on enhancing safety systems, increasing living space through the ADU addition, and upgrading the overall structural integrity, as evidenced by the various permits for seismic work and complete systems overhauls.

Risk rating

How 3508 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.
