Rent & eviction protection

Is 105-107 Highland Ave 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.

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 1910
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.

The building has undergone several significant plumbing infrastructure improvements in recent years, including a completed gas house-line extension in August 2024, a building sewer line replacement in 2013, and multiple gas house-line extensions in 2011 covering all five units. Historical records show window replacements were completed in 2015, involving 21 street-facing wood windows.

The building has experienced persistent plumbing issues, with multiple sewer problems documented between 2023-2024, including active complaints about sewer backups affecting access areas and adjacent properties. The property has a history of regulatory oversight, including a 2020 investigation of potential unauthorized unit conversions and periodic routine inspections revealing various violations. Notable health and safety concerns emerged in 2023, resulting in active housing inspection cases related to plumbing and sanitation conditions. The building's fire safety compliance has been monitored over the years, with some violations noted in 2017 regarding blocked exits and storage issues, though these were subsequently abated.

Planning records show the completion of window replacement work, while fire incident records reveal only false alarms with no civilian injuries reported.

Risk rating

How 105-107 Highland Ave'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
3rdpercentile

Out of 1276 buildings in this neighborhood, 1238 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
