Rent & eviction protection

Is 4124 Judah 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 1959
2 or more units

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

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 6-unit, 2-story multi-family residential building at 4124 Judah Street, owned by Cloud Properties LLC, was constructed in 1959 and is currently undergoing a re-roofing project valued at $25,000 that was completed in April 2024. The building's history reveals several concerning issues from 1997, including serious health and safety problems such as mold infestation, sewage leaks, and electrical concerns, though these complaints were marked as abated within one to two days. More recent inspections from 2001, 2011, and a 2014 complaint about non-functional heat and CO monitors indicate some ongoing maintenance and safety monitoring in the last two decades.

The property has generated multiple 311 calls in recent months (between November 2024 and January 2025), primarily related to garbage and debris on surrounding streets, with the most critical issues being encampments and sidewalk defects reported in January 2025. While the building itself has had relatively few direct complaints in recent years, the surrounding area has faced various challenges, including reports of illegal parking, abandoned furniture, and graffiti. A parking violation complaint in 2024 regarding a car parked in front of Unit 3 was investigated but found to have no violation. The combination of historical building issues from the 1990s and ongoing street-level concerns from recent 311 calls suggests an environment that has experienced both significant past challenges and current neighborhood maintenance issues, though the recent re-roofing project indicates some ongoing investment in building maintenance.

Risk rating

How 4124 Judah 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
10thpercentile

Out of 632 buildings in this neighborhood, 569 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
