Initial analysis

The two-unit residential building at 701 Webster Street in Alamo Square, owned by Raul & Denise Arriaza, is a 2-story flats and duplex structure built in 1900. The property has undergone several significant maintenance and compliance events over its history. In 2017, the building received a complete roof replacement valued at $9,800, and in 2008, the plumbing system was upgraded with a house trap and sewer replacement. A notable compliance issue arose in 2006 when two basement rooms were reported as illegal sleeping quarters with inadequate headroom, leading to abatement proceedings that were resolved by April 2007. More recently, there have been two carbon monoxide-related incidents recorded in 2024, though neither caused civilian injuries, and several 311 calls regarding street conditions and graffiti incidents between August 2024 and January 2025, which were generally addressed by city services.

The building's permit history shows regular maintenance activities, including multiple street space permits (2016, 2007) and the aforementioned roof and plumbing work. The property has experienced four service-related calls from the fire department, primarily for public service matters and false alarms, with one carbon monoxide detector activation and one confirmed incident, though no civilian injuries were reported in any of these events. Recent 311 calls in late 2024 have primarily concerned street cleaning issues, including reports of garbage and debris, though these were typically resolved promptly by city services. The building appears to have maintained compliance with basic safety requirements since the resolution of the 2006 violations, with regular maintenance activities documented through building permits.

Risk rating

How 701 Webster 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
91th percentile

Out of 305 buildings in this neighborhood, 27 are predicted to be safer.
