Rent & eviction protection

Is 1870 Washington 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 1923
2 or more units

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.

Built 1923
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 12-unit, 3-story apartment building at 1870 Washington Street in Pacific Heights, built in 1923, has undergone several significant improvements and faced numerous challenges in recent years. Most notably, the building completed a mandatory soft-story seismic retrofit in 2015 at a cost of $206,000, achieving compliance with San Francisco's wood frame seismic retrofit program. Recent electrical upgrades were initiated in October 2024, with permits issued for replacing fuse disconnects across eight breaker panels and installing fire warning devices. A concerning current issue is documented as of December 2024, where residents report heating system failures and unresolved mail security problems following a June 2024 incident with broken mailboxes. The building has a documented history of heat-related problems, including violations in 2004 and complaints in 2018 and 2024 regarding heating system failures.

The property has faced multiple safety and maintenance challenges, particularly between 2004-2005 when it experienced numerous violations that required remediation, including issues with handrails, ceilings, heating, fire safety systems, and more. Recent fire safety violations from 2023-2024 indicate ongoing concerns, with issues noted regarding the alarm system, sprinklers, fire extinguishers, and sleeping area requirements, though many have been subsequently corrected or abated. The building's systems have received attention over the years, including a steam boiler replacement in 2018 and various electrical upgrades. Historical records show earlier maintenance work including stair repairs in 2010 and reroofing in 1992, though some recent complaints have arisen regarding unauthorized roofing work in 2024.

Risk rating

How 1870 Washington 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
27thpercentile

Out of 963 buildings in this neighborhood, 703 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
