Rent & eviction protection

Is 840-842 Valencia 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.

Just-cause eviction

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

840-842 Valencia Street is a three-story multi-family residential building with 5 units, constructed in 1924 and currently owned by Rex C H Cheung and May Chan R. The property has undergone several significant improvements, most notably a major restaurant renovation in 2017 costing $220,000 that included kitchen remodeling, washroom relocation, bar addition, lighting installation, and electrical upgrades. This followed substantial restaurant infrastructure work in 2004-2005, including the installation of fire sprinklers, new HVAC systems, and concrete slab repairs, all suggesting a well-maintained commercial component. The building has experienced various maintenance issues over the years, with the most recent complaints from late 2024 regarding peeling paint, weatherproofing concerns, and lead paint notifications. These violations, though significant, were typically addressed relatively promptly, with previous issues including roof leaks (2008), pest problems (2009), and multiple painting violations being resolved through normal channels.

Recent activity at the property includes several 311 calls in late 2024 regarding illegal parking and street cleaning issues, as well as some shared spaces complaints documented by the fire department in 2022. The building's commercial space has maintained its restaurant status through proper channels, with approvals confirming its "Bona Fide Eating Place" designation requiring 51% food sales. The property's maintenance history shows a pattern of periodic upkeep and compliance with fire safety requirements, though some recent inspections have noted multiple interior surface issues that were subsequently addressed. The extensive permit history indicates regular investment in building maintenance and improvements, particularly focused on the ground floor commercial space, while the upper residential units have experienced fewer documented issues.

Risk rating

How 840-842 Valencia 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
36thpercentile

Out of 799 buildings in this neighborhood, 511 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.
