Rent & eviction protection

Is 129-131 Octavia 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.

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.

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 129-131 Octavia St is a 2-story, 4-unit multi-family residential building located in Hayes Valley, built in 1883 and owned by Olszewski Marek & Borecki N. The building has undergone several significant repairs and improvements over the past two decades, with the most recent major work occurring in 2016 when anchor bolts and fastening plates were installed at the existing sill to brick footing at a cost of $7,500. Earlier structural work included stairway cement repairs in 2007 ($10,000) and siding and window replacement in 2004 ($13,000). The building faced multiple violations in 2002 related to safety concerns, including issues with fire escape ladders, handrails, and gas shutoff tools, though all these violations were abated by May 2003.

A notable complaint was filed in 2008 alleging unauthorized conversion from 4 to 2 units with unauthorized exterior stair construction, though this case was ultimately closed in 2012. More recently, in April 2018, there was an inspection regarding sidewalk garbage and rodent issues, though this complaint is currently listed as not active. The building's utility infrastructure saw improvements in 2003 with the completion of undergrounding conversion work. Planning records indicate attempts to legalize a unit merger from 4 to 2 units, with one application cancelled and another closed without approval. Recent 311 calls from late 2024 show recurring issues with garbage and debris on the property grounds, though these are primarily external to the building itself and have been addressed by city services.

Risk rating

How 129-131 Octavia 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
71stpercentile

Out of 1027 buildings in this neighborhood, 298 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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.

Neighborhood (ZIP code)

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
