Rent & eviction protection

Is 43-47 Jasper Pl 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 1910

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 1910
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 three-unit, 1910 Telegraph Hill building at 43-47 Jasper Place, owned by Peter W Saltzman and Gioconda R, has undergone several significant structural and safety-related improvements over the past decade. Most notably, in 2019, the building underwent substantial voluntary seismic strengthening work costing $48,000, including foundation replacement and shear wall installation, along with plumbing improvements including new underground piping and laundry facilities. This followed earlier attempts at similar work in 2015 (withdrawn) and an upgrade proposal in 2016 that included adding a roof deck and laundry facilities. The building experienced a concerning period of safety issues in 2017, including multiple fire code violations related to smoke alarms, storage of combustible materials, and construction debris, as well as problems with heating systems and unapproved electrical wiring. These violations were subsequently abated by June 2017.

Historical records show earlier maintenance work including reroofing (1997) and stairway repairs (1997), while more recent records from 2023-2024 indicate ongoing issues with garbage and debris management in the surrounding area, though these are external to the building itself. The property has had several routine inspections over the years, with most violations being resolved within a reasonable timeframe. There was also a complaint about excessive hoarding in 2014 that was addressed, and all known fire safety violations from 2017 have been officially marked as abated. The building's recent history suggests improved structural integrity following the 2019 work, though it experienced significant safety-related challenges in 2017 that required remediation through various permits and corrections.

Risk rating

How 43-47 Jasper Pl'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
18thpercentile

Out of 684 buildings in this neighborhood, 561 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
