Rent & eviction protection

Is 3631 18Th 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 1905

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 1905
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

Located in Mission Dolores, this two-unit, two-story multi-family residential building was constructed in 1905 and is currently owned by the Hong D Lee Revocable Living Trust. The property has undergone several significant improvements over the past decade, including a comprehensive electrical upgrade in 2015 that involved installing 15 new 110v outlets and two subpanels for both units, and more recently, exterior stair repairs in 2024 valued at $12,500. Historical records show earlier maintenance work such as reroofing completed in 1990.

The building's recent history has been marked by several infrastructure and urban maintenance issues in the surrounding area, particularly in late 2024, with multiple reports of graffiti, garbage, and debris on the sidewalk, though these were resolved through official channels. There were two incidents of encampment situations recorded in October 2024 near the property, one of which required intervention. The property has experienced three alarm-related incidents requiring fire department response, though none involved actual fire situations or civilian injuries. The building and its immediate vicinity have shown typical urban maintenance challenges, with most issues being promptly addressed by city services.

Risk rating

How 3631 18Th 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
86thpercentile

Out of 799 buildings in this neighborhood, 112 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.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

Neighborhood location

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