Initial analysis

The three-story multi-family residential building at 1784-1788 Union Street in Cow Hollow, owned by Susan Li, was constructed in 1902 and contains four units with ground floor retail space. The property has undergone several significant renovations and improvements over the years, with substantial work occurring between 2004-2009 including foundation work, retail space improvements, and plumbing updates. Most notably, there was a period of electrical and heating system deficiencies in 2021, with complaints filed regarding non-working outlets and lack of heat in habitable rooms, though these issues were resolved by October 2021 with the installation of new baseboard heaters throughout the residential units. The building received multiple plumbing, electrical, and foundation improvements during its 2004-2009 renovation period, including repiping of water systems and electrical upgrades.

Recent activity at the property has primarily consisted of maintenance and regulatory compliance matters, with multiple 311 calls in January 2025 regarding overflowing garbage, though these were not directly related to building conditions. The building experienced one documented fire incident in 2016 involving a contained cooking fire with no injuries reported, and there was a brief period in 2010 regarding lead paint concerns and weatherproofing issues, both of which were subsequently resolved. A psychic reading business was reportedly operating without authorization at one point, though this appears to have been addressed. The most recent significant building improvements include the electrical heating system upgrade in 2021 and various maintenance activities documented through building permits, with no active violations or complaints as of the latest records.

Risk rating

How 1784-1788 Union 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.
