Rent & eviction protection

Is 1772-1776 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 before 1979
Built 1900
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1772-1776 Union Street is a three-story, multi-family residential building constructed in 1900, containing three units and owned by the Chew/Chen Family Trust. The building has undergone several significant renovations and maintenance work over the past few years, with the most recent being the repair of dry rot on rear stairs in early 2023 ($1,800), the installation of new furnaces and air conditioning units in March 2023, and extensive plumbing upgrades in late 2022 including new water heaters, supply lines, and waste pipes for all units. In 2021, a substantial renovation ($100,000) was completed involving kitchen and bathroom remodels in all units, including electrical upgrades and gas furnace replacement.

The building has faced multiple building complaints and compliance issues in recent years, with particular concern in 2023 regarding unauthorized construction and a potentially illegal rear extension measuring 8 feet. Complaints were filed in June 2023 about unpermitted work related to a cooling system installation on the roof, and in 2019 regarding unauthorized plumbing work. Historical records show consistent attention to maintenance issues, including dry rot repairs on rear stairs as far back as 1990. The property has also experienced periodic infrastructure improvements, such as a roof replacement (permit filed in 2004), though this permit ultimately expired. Recent street-level activity around the property has generated typical urban service requests, including reports of sidewalk cleanliness issues and damaged parking meters, though these are generally unrelated to the building's condition or management.

Risk rating

How 1772-1776 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
6thpercentile

Out of 861 buildings in this neighborhood, 809 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
