Rent & eviction protection

Is 3410-3420 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.

Built before 1979
Built 1912
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.

15+ years since occupancy
Built 1912
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 18-unit multi-family residential building at 3410-3420 22nd Street, built in 1912, has undergone significant recent renovations and improvements, including completed soft-story seismic retrofitting in 2021, multiple unit renovations in 2021-2022, and the conversion of former commercial spaces to new uses. Notable improvements include the conversion of units #3 and #506 to add washer/dryer facilities and bathroom rehabilitation in 2022, and the transformation of a commercial space into a hair salon in late 2022, which involved both tenant improvements and utility upgrades. The building has experienced some recurring fire safety issues, with recent violations in 2023 related to sleeping area requirements, though previous violations for fire escapes and alarm systems from 2022-2024 have generally been corrected promptly. A concerning active complaint from August 2024 regarding an unpermitted hand sink installation in the former restaurant space and a general maintenance complaint from September 2023 warrant attention.

The property has maintained compliance with major safety requirements, including the completion of its mandatory Tier 4 soft-story retrofit program. Historical records indicate a period of violations in 2016 related to various safety issues, including lead abatement, which were all addressed within a month. Recent construction and renovation work has primarily focused on modernizing units and improving building systems, including multiple bathroom and kitchen renovations across various units, though there have been some instances of expired permits that may require clarification. The building's location has experienced periodic issues with garbage collection, as evidenced by multiple recent 311 calls regarding overflowing city garbage cans in early 2025, though these appear to be external to the building itself.

Risk rating

How 3410-3420 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
2th percentile

Out of 1278 buildings in this neighborhood, 1252 are predicted to be safer.

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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 6.9%
Moderate concern 72.4%
Severe concern 20.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
