Rent & eviction protection

Is 19-23 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 before 1979
Built 1909
2 or more units
3 units
Property type
Multi-Family Residential

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1909
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 residential building at 19-23 Jasper Place in Telegraph Hill, currently owned by the Yee Family Trust since 2016, has undergone significant modifications since its 1909 construction. Most notably, between 2016-2018, the property experienced extensive renovations across all floors, including kitchen relocations, bathroom remodels, and electrical upgrades, with particular attention to legalizing previously unauthorized spaces. A concerning pattern of complaints regarding unauthorized unit modifications emerged between 2004-2012, particularly focusing on basement alterations, including an illegal unit with kitchen and bathroom facilities. These violations, along with multiple fire safety issues (such as fire extinguisher maintenance and alarm system problems), were ultimately resolved by September 2012.

The building's infrastructure has been actively maintained, with recent plumbing work including a 2021 sewer lateral and p-trap replacement using trenchless technology, demonstrating adherence to modern standards. There were several housing quality issues noted in the early 2010s, including mold problems and water leaks, though these appear to have been addressed through subsequent renovations. The most recent building data shows primarily routine maintenance and cleanup activity in the surrounding area, with no active building violations or significant structural concerns recorded since 2018. A single carbon monoxide detector activation incident was reported, though no CO was detected and no injuries occurred. The property has maintained compliance with housing codes since resolving its previous violations, with recent work focusing on regular maintenance and infrastructure upkeep rather than major modifications.

Risk rating

How 19-23 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
53rdpercentile

Out of 684 buildings in this neighborhood, 321 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
