Rent & eviction protection

Is 2844 Lyon 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.

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

2844 Lyon Street is a 12-unit multi-family residential building constructed in 1928, currently owned by 2844 Lyon Street Owner LP. The three-story structure has undergone significant renovations in recent years, including the addition of four accessory dwelling units (ADUs) in 2020, which converted the garage and crawl space areas. Major safety improvements have been implemented, including a comprehensive fire sprinkler system installation (2022), fire alarm replacement system (2023), and ongoing fire safety upgrades through 2024. The building has active non-compliance status in the mandatory Soft Story Retrofit Program, with a violation filed in 2019 regarding earthquake safety, though a permit for seismic work (2020) was filed for $89,000.

The property has experienced several maintenance and safety issues in recent years. Between 2022 and 2024, there were multiple complaints regarding heating, ventilation, and structural problems, including a ceiling collapse (March 2023) and ventilation issues (April 2023). The building's systems have undergone extensive upgrading, including a main electrical service upgrade (2022), boiler replacement (2022), and comprehensive unit renovations in 2019-2023. Recent complaints (September 2024) noted problems with construction barriers blocking entrances and sidewalks, and there have been multiple concerns regarding garbage and debris around the property. The building has a history of fire safety violations, though most have been corrected. A notable recent complaint in November 2024 regarding alarm systems was found to have "No Merit," while a similar complaint from October 2024 had "Condition Corrected" status.

Risk rating

How 2844 Lyon 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

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.

NOV rate, owner's portfolio

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

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.

12-Month severity forecast
No violation 14.4%
Moderate concern 69.7%
Severe concern 15.8%
