Rent & eviction protection

Is 2836 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.

Built before 1979
Built 1921
2 or more units

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.

15+ years since occupancy
Built 1921
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-unit residential building at 2836 Lyon Street in Cow Hollow, owned by 2836 Lyon Street LLC, has undergone several significant improvements since its construction in 1921. Most notably, in January 2024, the property completed a comprehensive rewiring project that included both apartments, featuring two 100-amp subpanels, indicating a substantial upgrade to the building's electrical infrastructure. Prior improvements include reroofing work completed in 2002 (costing $6,000) and two major renovation projects in the mid-1980s: the enclosure of the lower area under the sunroom in 1985 and structural modifications involving post relocation and beam addition in 1986. Minor interior improvements were made in 1984 including the installation of pocket doors, windows, sheetrock, and new sinks.

The property has experienced periodic issues with street cleanliness in the vicinity, as evidenced by three 311 calls since 2019, though these were related to public street conditions rather than building-specific problems. The most recent incidents occurred in 2024, involving reports of human waste and overflowing city garbage cans, while an earlier complaint from 2019 concerned loose garbage on the street. These external environmental issues were all resolved through city services and do not directly reflect on the building's maintenance or resident conditions. The building's documented history shows regular maintenance and improvements, with the most recent electrical upgrade representing a significant modernization of the property's systems.

Risk rating

How 2836 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

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
69thpercentile

Out of 861 buildings in this neighborhood, 267 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.
