Rent & eviction protection

Is 4433 Lincoln Way 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 1970

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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.

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 two-story multi-family residential building at 4433 Lincoln Way in the Outer Sunset neighborhood, owned by Sum Mau Huynh & Anh Tu Ly 2, was constructed in 1970 and contains 5 units. The property has undergone several routine safety inspections, with the most recent taking place in April 2018, though most building violations and complaints are from past years. Notably, a significant cluster of violations was documented in November 2001, primarily related to fire safety concerns, including egress obstructions at fire escapes, fire proofing issues in the garage ceiling, problems with the central alarm system, and various fire equipment maintenance needs such as recharging fire extinguishers. These violations also encompassed gas utility safety requirements. While all these violations were ultimately resolved (some marked as abated in December 2001), they indicate a period of concerning safety maintenance.

More recent history shows several infrastructure maintenance issues outside the building, including a 2023 incident with an exposed PG&E utility vault/electric cover, and regular occurrences of sidewalk cleaning and loose garbage removal documented between 2015 and 2024. A rodent/insect infestation complaint was filed in October 2020, though the resolution status indicates it was transferred to the Department of Public Health's Environmental Health Healthy Housing & Vector Control Program. Parking enforcement issues have occurred multiple times between 2020 and 2024, with citations issued for vehicles blocking driveways. While many of these issues have been resolved through normal city procedures, they collectively represent various maintenance and safety concerns that have affected the property over time.

Risk rating

How 4433 Lincoln Way'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
27thpercentile

Out of 632 buildings in this neighborhood, 461 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.

Number of units

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

Building size

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

Neighborhood location

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