Rent & eviction protection

Is 173-175 Valparaiso 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 1930
2 or more units

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

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1930
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 173-175 Valparaiso Street in San Francisco's Russian Hill neighborhood is a two-unit, two-story multi-family residential building constructed in 1930, currently owned by Berry Hershel & Elsa. The building has undergone several significant maintenance updates over the years, including a comprehensive window improvement project in 1996 when 35 aluminum windows were installed, and a sewer lateral replacement completed in May 2022, which indicates attention to infrastructure maintenance. Historical records show a roofing project from 1995 and a furnace replacement in 2008, though the latter was marked as expired in the permit system.

The building's recent history shows minimal internal issues, with only one Rent Board-related service request in October 2023 regarding fee housing inventory matters, which was resolved with a unit count change. The property's external maintenance history includes several 311 calls related to street cleaning in 2016-2018, typically involving loose garbage on the street, though these were general neighborhood issues rather than building-specific problems. There was one significant plumbing incident in 2011 involving a sewage backup, and the property underwent substantial exterior improvements in the mid-1990s. The most recent building-related activity was in 2023, when the Rent Board modified the unit count and communicated with the property owner, though this event did not indicate any structural or maintenance concerns. The property's maintenance record shows regular upkeep of essential systems, with particular attention paid to windows and the building's exterior components during the specified periods.

Risk rating

How 173-175 Valparaiso 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
94thpercentile

Out of 1133 buildings in this neighborhood, 68 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
