Rent & eviction protection

Is 689-691 Lisbon 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 1910

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 1910
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 three-unit multi-family residential building at 689-691 Lisbon Street in the Excelsior neighborhood, owned by Katharine Alsop, has a documented history dating back to 1986. The two-story structure, built in 1910, has undergone several maintenance and repair projects over the years, with particular attention to its exterior features. Recent building improvements include a 2017 deck repair project costing $20,000. Between 2005 and 2006, the property experienced significant issues with mold and wood rot, particularly affecting the rear stairs and decks, leading to multiple repairs totaling approximately $7,000. These problems were serious enough to prompt three housing complaints in 2005 regarding mold, wood rot, and health concerns, though these complaints were eventually abated. Earlier maintenance work included reroofing in 1997 and various structural repairs such as underpinning work in 1986, repair of stair ballisters and porch guardrails in 1997, and work on stairs and landing repairs in 2005.

The property has generated regular maintenance calls in recent months, particularly regarding garbage and debris on the property, with multiple reports filed between November 2024 and January 2025, all of which have been resolved. There have also been several parking-related complaints in the vicinity during this period, including requests for enforcement of sidewalk parking and driveway blocking, though some of these cases were either invalid or the officers were unable to locate the reported issues. The recent clustering of debris-related complaints suggests ongoing challenges with proper waste management in the immediate area, though these appear to be primarily external to the building itself. It's worth noting that the most serious historical issues with mold and structural decay appear to have been addressed through the various repair permits issued between 2005 and 2017, with no more recent building permits indicating similar concerns.

Risk rating

How 689-691 Lisbon 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 337 buildings in this neighborhood, 104 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.
