Rent & eviction protection

Is 398 West Portal 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.

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 five-story, 25-unit multi-family residential building at 398 West Portal Avenue, built in 1929 and owned by Ceg West Portal Lp, has undergone significant recent fire safety upgrades. Most notably, in 2023-2024, the building received comprehensive fire alarm system improvements including the installation of manual pull stations, smoke detectors, low-frequency sounders, and a new fire alarm control panel, with work completed at a total cost exceeding $62,000. The building has experienced recurring fire safety issues, with multiple violations and complaints between 2002 and 2023, including three fire alarm-related violations since 2020, and a sleeping area requirement violation in October 2023.

The property has a documented history of maintenance challenges and safety concerns. Major plumbing and electrical work includes a boiler replacement in 2017 and bathroom upgrades in 2020. Significant structural work was performed in 2013, including waterproofing repairs to three concrete back elevations at a cost of $125,000. Several serious complaints were filed in 2013 regarding lead paint removal work, with concerns about safety practices and potential occupant exposure. The building has experienced various habitability issues over the years, including mold problems (2006-2007), fire escape maintenance concerns (2002), and heating failures (2008), though most violations were abated. While the building's recent fire safety upgrades demonstrate improved safety measures, the property has a history of requiring ongoing maintenance and systems upgrades to meet compliance standards.

Risk rating

How 398 West Portal 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

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
0thpercentile

Out of 24 buildings in this neighborhood, 24 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.

Building size

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

Neighborhood location

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