Rent & eviction protection

Is 1700-1704 Union St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built 1906

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1906
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The three-unit, three-story multi-family residential building at 1700-1704 Union Street in Cow Hollow, owned by H/s Partners Ii Lp, has a history dating back to 1906. The property has undergone several maintenance and improvement projects over the years, including a roof deck handrail repair in 2008, stairway extension to the roof in 1984, and interior partition modifications in 1986. More recent developments include two complaints filed in September 2024 regarding unauthorized residential use of a unit within a medical commercial space, though these cases are currently listed as not active. The building has experienced four false fire alarm incidents and one contained cooking fire, with no reported injuries in any of these events.

The property has had multiple street space permits issued between 1984 and 2016, though one from 2008 was revoked. Recent maintenance issues have generally been addressed promptly, including tree maintenance and various sidewalk cleaning matters. Between June 2024 and January 2025, there have been several 311 calls regarding the property, primarily concerning garbage, debris, and street maintenance issues, all of which were resolved. While there were proposals for wireless telecommunications installations by AT&T and Verizon between 2014 and 2016, these projects were either withdrawn or closed. The building's most recent notable activity involves a December 2024 sewer service request that was resolved, and there are open matters related to a tree maintenance request from December 2024.

Risk rating

How 1700-1704 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
63rdpercentile

Out of 861 buildings in this neighborhood, 319 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

DBI complaints, owner's portfolio

Complaints across all of this owner's buildings over 7 years.
