Rent & eviction protection

Is 81-91 Water 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

The 6-unit, 3-story multi-family residential building at 81-91 Water Street in North Beach, owned by Chun Linda H S, has undergone several significant improvements and faced various regulatory challenges since its construction in 1908. The building completed important structural strengthening work in 2014 valued at $33,000, and underwent multiple kitchen renovations between 1998-2018, with the most recent work in 2018 costing $18,000 including cabinet, countertop, and sink replacements. More critically, the building faced mandatory seismic retrofit requirements as part of San Francisco's Soft Story Retrofit Program, which resulted in violations filed in 2018 that were eventually abated by November 2019, including the payment of monthly violation monitoring fees. The building's electrical system has seen substantial upgrades, including a 2004 installation of a new 200-amp service with seven meters and main switches, while plumbing and electrical work related to kitchen improvements continued into 2018.

The property has experienced regular maintenance and upgrades over the years, including window replacements in 2008 (installation of wood and vinyl windows) and various unit renovations throughout the 2000s. Several routine housing inspections have been conducted, revealing issues such as lack of hot water and missing smoke detectors in 2000, which were promptly addressed. The building's most recent history shows external challenges with street conditions, as evidenced by multiple 311 calls in 2024 regarding sidewalk cleaning needs, though these primarily relate to public space issues rather than building conditions. A minor cooking-related fire incident was recorded with no civilian injuries. The property has generally maintained compliance with building codes following past violations, though the timeline of repairs and upgrades suggests ongoing attention to maintaining and improving building safety and habitability.

Risk rating

How 81-91 Water 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
38thpercentile

Out of 362 buildings in this neighborhood, 224 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 permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

Building age

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