Rent & eviction protection

Is 101-109 Castro 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 1908
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 1908
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 6-unit, 3-story multi-family residential building at 101-109 Castro Street in Duboce Triangle, constructed in 1908, has undergone several significant renovations and faced various maintenance challenges over the years. Most recently, in 2024, Unit 109 is undergoing comprehensive renovations including kitchen and bathroom upgrades and replacement of siding on the south and east walls, with associated plumbing and electrical work valued at $100,000. The building has seen recurring stairway maintenance needs, with major repairs occurring in 1990, 2002, and 2017, suggesting ongoing structural attention is required in this area. The building experienced a notable set of violations in 2017 that were resolved by the end of the year, including issues with electrical systems, safety features, and weatherproofing, all of which were addressed through various permits.

The property's maintenance history shows regular attention to roof maintenance, with work completed in 1997 and 2022, though some permits from the 1990s are now expired. Recent 311 calls from late 2024 indicate some ongoing external issues near the property, including reports of sewage backup and multiple instances of debris removal needs, though these are street-related rather than directly involving the building structure. A cooking-related fire incident was recorded with no civilian injuries. The building's history also shows compliance with various safety requirements, including the installation of rescue windows in 2017 following a complaint. The property was listed as having a legacy business registry status for "Courtney's Produce," though this appears to be related to a different address.

Risk rating

How 101-109 Castro 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
63rdpercentile

Out of 287 buildings in this neighborhood, 106 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 age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
