Rent & eviction protection

Is 3135-3137 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 1902

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 1902
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 property at 3135-3137 Washington Street is a two-unit, two-story multi-family residential building located in the Pacific Heights neighborhood, constructed in 1902 and owned by Charlotte Kaapke Horton Kar. The building has undergone several significant infrastructure improvements over its lifetime, with the most recent and substantial work occurring in September 2024 when major electrical upgrades were completed, including house rewiring, installation of 30 outlets, 12 switches, 8 light fixtures, and replacement of two 100-amp subpanels. Prior to this, a sewer repair was conducted outside the building in January 2016.

The building's maintenance history includes a pair of plumbing permits obtained in August 1984 for the installation of hardrails, supply air vent, and plumbing work, though these permits have since expired. The property has had minimal incident reports in recent years, with only three 311 calls recorded: a paint shop service request in September 2023 that was resolved, a hazardous materials (glass) cleanup in May 2020 that was addressed, and an abandoned delivery truck report in August 2019 where the vehicle was gone upon arrival of authorities. The recent electrical upgrades suggest proactive maintenance of the building's infrastructure, particularly in addressing modern safety and functionality requirements.

Risk rating

How 3135-3137 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
73rdpercentile

Out of 963 buildings in this neighborhood, 260 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.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
