Rent & eviction protection

Is 3900-3902 22Nd 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.

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 1907
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 3900-3902 22nd Street is a three-story, two-unit multi-family residential building located in the Eureka Valley/Dolores Heights neighborhood, owned by Robert L. Fan and Rodani Leong. Built in 1907, the building underwent a significant conversion from a three-unit to a two-unit structure in 2009, which involved merging the lower first and second floors and was part of a legalization process documented in both building and planning records. The most recent major improvements include a comprehensive solar power system installation completed in 2024, consisting of 21 modules with an 8.085 kW capacity, and a bathroom remodel in 2020 that included extensive plumbing and electrical work.

The building's history includes several concerning safety issues from 2001, when multiple violations were recorded regarding inadequate shoring and bracing during garage excavation, though these appear to have been addressed given their current status as "Active" with no recent updates. The property has maintained regular building upkeep with various permits for window replacement, skylight installation, and multiple inspections completed successfully. Recent 311 calls from 2023-2024 show typical urban neighborhood concerns such as illegal postings, driveway blocking, and street cleaning issues, none of which indicate any building safety concerns. Two minor fire-related incidents were recorded in the building's history, both showing no injuries or significant events: one was a carbon monoxide detector activation with no CO detected, and another with no incident found upon arrival. The property has undergone recent modernization efforts including window upgrades in 2020, with 25 Marvin wood windows installed at a cost of $35,000, and a master bathroom remodel costing $30,000.

Risk rating

How 3900-3902 22Nd 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
95thpercentile

Out of 1278 buildings in this neighborhood, 64 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 location

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

Building age

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

Notices of Violation, owner's portfolio

DBI NOVs across all buildings this owner is registered on — a signal of systemic maintenance issues across the portfolio.
