Rent & eviction protection

Is 1115-1119 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 1948

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.

Built 1948
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 3-unit multi-family residential building at 1115-1119 Union Street in Russian Hill, built in 1948 and currently owned by John & Athena Konstin Revoc, has undergone significant renovations and improvements over the past decade. Most notably, in 2012-2013, substantial work was completed including a major second-level remodel ($60,000) featuring kitchen and bathroom updates, deck installation, and comprehensive electrical work ($60,000) involving new circuits, lighting, and smoke detectors. The building received additional safety upgrades with the installation of 12 sprinkler heads in late 2013 ($6,000) and a complete reroofing project in 2016 ($18,750). Infrastructure improvements include the replacement of three heating systems and water heaters in 2014, installation of on-demand water heaters, and a new fireplace.

The building's maintenance record shows attention to both basic upkeep and safety enhancements, though there were some violations in 2004-2008 that have since been resolved. These included issues with security features (deadbolts), handrails, stairs, and lead paint concerns, all of which were abated by April 2008. A more recent complaint from 2019 regarding generator noise during construction work suggests ongoing maintenance activities, though this issue was also marked as not active. The property has undergone significant modernization while maintaining compliance with building codes, as evidenced by the numerous permits and successful completion of major systems upgrades.

Risk rating

How 1115-1119 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
29thpercentile
