Rent & eviction protection

Is 1807-1815 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 1900

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 1900
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 property at 1807-1815 Union Street is a two-story, multi-family residential building with 6 units, constructed in 1900 and currently owned by 1800 Plus Union Street LLC. The building has undergone significant recent commercial activity, particularly with the introduction of the "Dumpling Union" restaurant in 2021, which involved major renovations including kitchen equipment installation, all-gender restrooms, and related electrical and plumbing work totaling approximately $157,000. In 2020-2022, substantial accessibility improvements were made to comply with the Accessible Business Entrance (ABE) program, including modifications to entrances at both 1809 and 1815 Union Street, with additional work on handrails and ramps costing approximately $16,000. The building's maintenance history shows generally responsible upkeep, though there was one building complaint in 2017 regarding unauthorized electrical work for outdoor heaters, which was promptly abated within one month.

Recent activity at the property has primarily focused on restaurant-related improvements and accessibility compliance. The most notable recent issue has been a series of nine consecutive reports of garbage and debris, specifically overflowing city garbage cans, in early January 2025, all of which were resolved through city services. The building appears to be well-maintained in terms of structural integrity, with proper permits obtained for recent modifications, including a new fire suppression system for kitchen equipment installed in 2022. A window replacement project was filed in 2019, and historical records show past concerns about unpermitted water heater installation in 1999 and unauthorized remodeling in 2005, though these issues were resolved over time. The property has been proactive in addressing accessibility requirements and maintaining compliance with building codes through regular updates and permit applications.

Risk rating

How 1807-1815 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.

Neighborhood percentile
48th percentile

Out of 861 buildings in this neighborhood, 448 are predicted to be safer.

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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 52.2%
Moderate concern 19.7%
Severe concern 28.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
