Rent & eviction protection

Is 3864-3866 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 1900

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 1900
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

This two-unit, two-story multi-family residential building located at 3864-3866 18th Street in the Eureka Valley/Dolores Heights neighborhood was built in 1900 and is owned by Gerald R & Shirley M Morett. The property has undergone several significant renovations and repairs over the past decade, with the most substantial work occurring in 2017 when major improvements were made to the upstairs unit (3866), including kitchen cabinet replacement, new floors, electrical and plumbing upgrades, and a complete electrical rewiring including installation of a 200-amp service, new subpanel, and extensive new circuitry for appliances and safety features. More recently, in 2022, the front door was replaced, and in September 2024, a furnace replacement was permitted.

The building has experienced several maintenance and safety issues over the years, with the most pressing concerns emerging in late 2024, including electrical violations, problems with electrical outlets, and issues with exhaust ducting for clothes dryers, which are currently listed as active violations. Previous violations from 2016 included problems with siding weatherproofing, missing trim, and lead-related concerns, all of which were abated by September 2016. The property has a history of fire safety concerns, though most incidents were related to false alarms rather than actual fires. Historical complaints from 2000 indicated issues with heating appliances and structural concerns, while a 2010 complaint noted multiple maintenance issues including rodent concerns and an overgrown backyard. Recent 311 calls from late 2024 have included reports of garbage, graffiti, and a noise complaint, as well as one open case related to parking enforcement. The building's maintenance history suggests periodic updates and repairs, though the recent emergence of multiple active violations indicates some current maintenance challenges.

Risk rating

How 3864-3866 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
83rdpercentile

Out of 1278 buildings in this neighborhood, 217 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.

Neighborhood location

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

Estimated permit spend (past 7 years)

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