50 Stanyan Blvd

Lone Mountain, SF 94118 1085040 11 units · 2 fl · 1962

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 50 Stanyan Blvd 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 two-story, 11-unit multi-family residential building at 50 Stanyan Blvd in the Lone Mountain neighborhood, owned by Toy Donald & Liang Rita, was constructed in 1962 and has undergone several significant improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2016-2018 (as a Tier 3 property), including ground floor reinforcement, shear wall modifications, and the installation of new anchor systems, demonstrating compliance with seismic safety requirements. Recent building improvements include the addition of two accessory dwelling units to the ground floor (permit filed in 2021), and numerous maintenance upgrades such as re-roofing (2018, $31,000), vinyl window replacement (2004), and various unit renovations.

The property has experienced recurring fire safety and maintenance issues, particularly evident from 2003-2023. Several fire safety violations were recorded, including alarm system and extinguisher maintenance issues in 2023 (recently abated), and a 2017 fire code violation regarding combustible storage. Prior violations from 2003 included problems with smoke enclosure doors, electrical outlets, fire proofing materials, and garbage receptacle placement, all of which were subsequently resolved. The building has undergone routine inspections, and while earlier records from the 1990s-2000s indicate issues with carpet maintenance, plumbing, and mildew, these problems appear to have been addressed. Fire department records show multiple service calls between 2008-2023, primarily related to equipment inspections and minor incidents, with no reported civilian injuries. Recent 311 calls (2023-2024) have primarily concerned exterior issues such as graffiti, sidewalk blockages, and garbage removal, suggesting ongoing challenges with property maintenance and trash management around the building's perimeter.

Risk rating

How 50 Stanyan Blvd'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 519 buildings in this neighborhood, 498 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.

Building size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
