Rent & eviction protection

Is 35-37 Castillo 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 1948

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-unit residential building at 35-37 Castillo Street in Visitacion Valley, owned by the Bertram Family Trust, was constructed in 1948 as a two-story flats and duplex structure. The property has undergone several significant infrastructure improvements, most notably in March 2009 when substantial electrical upgrades were completed on the first floor, including the transition from fuses to breakers, installation of two meters, and the addition of new electrical panels with varying capacities. Earlier maintenance work included reroofing undertaken in 1997, though this permit has since expired.

More recent concerns at the property warrant attention, particularly two incidents in August 2024 involving public health and mold/mildew issues, both of which were accepted for investigation. The building's environment has experienced multiple parking-related disturbances between 2021-2022, with several reports of double parking and illegal parking, though these issues were primarily street-related and have since been logged for city data collection purposes. While these parking incidents don't directly affect the building's habitability, they do reflect some neighborhood challenges. The property's electrical system improvements from 2009, including the installation of modern electrical infrastructure, suggest efforts to maintain and upgrade essential systems, though the status of some permits from this period is noted as expired.

Risk rating

How 35-37 Castillo 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
73rdpercentile

Out of 214 buildings in this neighborhood, 58 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
