Rent & eviction protection

Is 1392-1398 9Th Ave 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.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction

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 six-story, 34-unit apartment building at 1392-1398 9th Avenue in San Francisco's Inner Sunset neighborhood, owned by 336-350 Judah I3 LP, has undergone numerous improvements and faced several challenges since its construction in 1926. The property has seen significant recent updates in accessibility and utility systems, including two commercial entry upgrades in 2023 to comply with accessibility requirements, the installation of a duplex pressure-boosting pump system, and the replacement of water heating equipment with three tankless Rinnai boilers. Between 2019 and 2024, multiple residential unit renovations were completed, including kitchen and bathroom remodels, washer/dryer installations, and various infrastructure improvements. Noteworthy concerns have been documented regarding elevator reliability, with multiple complaints in 2021 about elevator failures impacting disabled residents, and a more recent water leak complaint from 2024.

The building has experienced recurring fire safety and maintenance issues, though many have been addressed promptly. Notable incidents include three fire alarm activations in 2020 (two for alarm system issues and one for street numbering concerns), and a violation for sleeping area requirements issued in October 2023. Historical issues from 2000 included various interior maintenance violations, including problems with floor coverings, smoke detectors, egress obstruction, water damage, and security devices, though these were abated by 2001. The property's telecommunications infrastructure has been actively maintained, with multiple permits issued for antenna installations and upgrades, most recently in August 2024. While the building has experienced periodic water-related issues, including a 2018 complaint about ceiling leaks affecting multiple units, recent improvements to the building's infrastructure demonstrate ongoing maintenance and upgrading of facilities.

Risk rating

How 1392-1398 9Th Ave'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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 1493 buildings in this neighborhood, 1493 are predicted to be safer.

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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Building size

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

12-Month severity forecast
No violation 6.1%
Moderate concern 79.2%
Severe concern 14.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
