Rent & eviction protection

Is 451-457 Locust 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 1924

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.

15+ years since occupancy
Built 1924
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 four-unit, two-story building at 451-457 Locust Street in Presidio Heights, constructed in 1924, has experienced several significant events over the past seven years that impact resident safety and building integrity. Most notably, there was a serious structural incident in early 2022 involving the removal of a cement column in the garage without proper permits, leading to floor shifts in Unit 455 and a lengthy investigation process that included a final warning notice in March 2022 and a director hearing in October 2023. The building underwent multiple renovation projects during this period, including the installation of a glulam beam system in early 2022 (though initially disputed), ceiling sheetrock installation and lighting work in late 2022, and restoration of interior windows due to water intrusion. Additional concerns have been documented, such as electrical issues reported in April 2022, unpermitted construction work with hazardous lead paint conditions in February 2022, and multiple complaints regarding construction work occurring outside permitted hours or beyond permitted scope in 2021, including unsafe roofing work that posed risks to pedestrians and failed to adhere to COVID-19 safety protocols.

The building's maintenance and inspection record shows ongoing attention to various issues, with nine building permits totaling nearly $295,000 in construction costs over the past seven years. Recent work completed in 2023 included the replacement of front stairs due to deterioration. While the property has generated numerous 311 service requests (161 in total), these have primarily concerned routine maintenance issues such as garbage, parking, and tree overgrowth, rather than safety concerns. The building's record indicates a pattern of unpermitted work and inadequate communication with residents during construction activities, though many of the more recent permits and repairs appear to address previously identified safety concerns. The most recent building permits and completed work suggest ongoing efforts to maintain and improve the property's structural integrity and resident safety, though the history of violations and complaints indicates past challenges with proper permitting and construction practices.

Risk rating

How 451-457 Locust 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.

Neighborhood percentile

Out of 181 buildings in this neighborhood, 156 are predicted to be safer.
