Rent & eviction protection

Is 1823-1825 Clement 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

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

The 1823-1825 Clement Street property is a two-story mixed-use building constructed in 1906, containing five residential units and commercial space, currently owned by Tommy Fu Wing Tse. The building has undergone several significant renovations and faced various compliance issues over its history. Most recently, in August 2023, improvements were made to install a power door operator and related landing modifications at a cost of $3,500. Previous major works included a 2021 plumbing upgrade replacing the house trap and approximately 40 feet of underground sewer pipe, and a series of unauthorized construction issues were resolved between 2003-2004, including illegal storage room conversions and various interior violations.

The building experienced notable inspection and violation activity in 2004, with multiple citations related to fire safety, electrical systems, lead paint hazards, and plumbing issues, all of which were abated by July 2004. Earlier complaints from 2003 indicated unauthorized unit construction, and there were water-related issues documented in 1997 regarding siding and leakage problems. The property has undergone regular maintenance and improvement work, including kitchen and bathroom remodels in 2006 (with corresponding electrical upgrades), and various infrastructure updates. Recent maintenance records show attention to building accessibility and safety features, while 311 calls from 2020-2024 primarily involve external issues such as parking concerns and waste management, rather than building-specific problems.

Risk rating

How 1823-1825 Clement 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
19thpercentile

Out of 2250 buildings in this neighborhood, 1822 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

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