Initial analysis

1750 Vallejo Street is a 6-story, 40-unit multi-family residential building located in Pacific Heights, owned by Zebra Vallejo LP and constructed in 1931. The property has undergone significant renovations over the past decade, with multiple unit upgrades including comprehensive bathroom and kitchen remodels in Units 101, 201, 205, 206, 406, 502, and 106 between 2014 and 2024, some involving substantial changes like adding new bathrooms and bedrooms. Most recently, in June 2024, Unit 205 received a $36,000 renovation including kitchen and bathroom updates. The building is currently addressing a safety violation issued in November 2023 regarding sleeping area requirements, which remains open as of October 2023.

Safety systems in the building have received considerable attention, with mandatory improvements to the fire alarm system including low-frequency horn upgrades in 2023, and previous work in 2016-2022 addressing sprinkler/standpipe systems. There have been multiple fire alarm activations recorded, though all were unintentional with no civilian injuries reported. Historical building complaints include periodic issues such as non-vented dryers (1997-1998), water damage (1995), and a no-heat complaint (2021), though these are no longer active. Recent 311 calls have primarily concerned parking violations and street cleaning issues. The building's maintenance history shows consistent investment in unit upgrades and safety systems, though there have been occasional permit compliance concerns as evidenced by a 2023 complaint about unauthorized construction work.

Risk rating

How 1750 Vallejo 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.

Model explanation

What's driving this score

Number of units

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 20.3%
Moderate concern 70.3%
Severe concern 9.5%
