1135 Stanyan St

Cole Valley/Parnassus Heights, SF 94117 2630007A 12 units · 3 fl · 1924

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 1135 Stanyan 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 1924
2 or more units

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 1924
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 10-unit, 2-story multi-family residential building at 1135 Stanyan Street, owned by Stanyan Hill & Irving Arms, was constructed in 1924 and has undergone significant improvements and renovations over recent years. The property completed mandatory seismic retrofit work in 2014 (as a Tier 3 soft-story building) and underwent a substantial conversion project in 2016 that transformed the garage space into two efficiency units, including vintage carriage door replacements and tree plantings. The building has maintained consistent fire safety upgrades, including multiple fire alarm system improvements between 2019-2021 to meet San Francisco fire code requirements, and has addressed sprinkler system installations, particularly during the 2019 ADU construction phase. While there have been several fire safety-related complaints and violations over the past few years, including a 2024 violation for alarm system maintenance, all issues were promptly addressed, with the building generally demonstrating good responsiveness to fire safety requirements. Recent maintenance history shows regular upkeep of essential systems, including a 2018 main service upgrade to 300-400 amps, though some recent 311 calls regarding street cleaning and parking issues have been recorded, primarily relating to the immediate vicinity rather than the building itself. The property had a cluster of fire safety violations in 2002 that were all abated by January 2003, and routine housing inspections have been conducted in recent years, showing overall compliance with safety standards.

Risk rating

How 1135 Stanyan 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
4thpercentile

Out of 526 buildings in this neighborhood, 505 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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