Rent & eviction protection

Is 1900 Jackson 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 1957

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

1900 Jackson Street is a 9-unit, 3-story multi-family residential building located in San Francisco's Pacific Heights neighborhood, owned by 1900 Jackson Street LLC and constructed in 1957. The property has undergone several significant improvements and faced various compliance issues over the years. Most notably, the building completed mandatory soft-story retrofit work in 2017 (with a cost of $30,000) as required under San Francisco Building Code Chapter 34B. Recent building improvements include a 2020 permit application to install new bike racks and storage in the basement, and the installation of new emergency lighting in 2020 to address a fire code violation.

The building has a documented history of maintenance and safety compliance issues, particularly between 2010-2016, when violations were recorded related to fire escape maintenance, dishwasher air gap fittings, hot water boiler permits, and security requirements. All of these violations were eventually abated by February 2016. More recent concerns include multiple fire alarm system activations due to malfunction and false alarms, though no civilian injuries have been reported from these incidents. The property has also attracted attention from the Academy of Art University enforcement program, with records indicating a change of use investigation in 1999 regarding the building being used as transient housing, as well as subsequent enforcement actions related to group housing conversion and unauthorized signs. Recent 311 calls from late 2024 primarily relate to street maintenance issues, including garbage disposal and pavement defects, though these are external to the building itself.

Risk rating

How 1900 Jackson 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

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.

Number of units
