Rent & eviction protection

Is 2443-2447 24Th 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.

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.

Built 1905
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 property at 2443-2447 24th Street is a three-story, four-unit multi-family residential building with street-level retail space, constructed in 1905 and currently owned by Frank R. and Shirley A. Stonich. The building has experienced numerous permit-related issues over the past several years, most notably concerning unauthorized basement habitability conversions and ground floor unit legalization. Since 2018, multiple attempts have been made to legalize various improvements, including a second-floor bathroom and a ground floor unit, though some permits expired or were withdrawn, leading to enforcement actions. A significant ongoing concern is the basement conversion project (2022 violation) involving storage rooms converted to habitable space without proper lighting, ventilation, or egress, which remains active as of 2024. The building underwent substantial improvements in 2016-2017, including the installation of a fire sprinkler system, complete electrical upgrades, plumbing renovations, and bathroom remodels across multiple units.

Recent complaints from 2023-2024 have highlighted various concerns, including alleged unauthorized ground floor retail-to-residential conversion, permit violations, and improper garage bin placement. There have been multiple enforcement actions regarding expired permits and unauthorized work, with the most recent being a March 2024 complaint about the expired bathroom legalization permit. The property has a history of compliance issues dating back to 2006-2008, including unauthorized foundation work and permit violations, though these have since been resolved. Recent 311 calls from late 2024/early 2025 primarily involve sidewalk usage and garbage management issues. While many improvement projects have been completed successfully over the years, including the installation of two furnaces, water heaters, and comprehensive electrical upgrades, the building continues to face challenges related to unpermitted modifications and compliance with building codes.

Risk rating

How 2443-2447 24Th 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
2ndpercentile

Out of 2380 buildings in this neighborhood, 2332 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Number of units

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