Rent & eviction protection

Is 16 Laguna 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 1931
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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.

Built 1931
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

16 Laguna Street is a 6-story, 19-unit multi-family residential building constructed in 1931 and currently owned by 16-50 Laguna I2 LLC. The building has undergone substantial recent improvements, including a major renovation project filed in 2021 to add four accessory dwelling units on the first level (costing approximately $3.4 million), and several individual unit remodels between 2018-2021 involving kitchen and bathroom upgrades, washer/dryer installations, and various other improvements across multiple units (costs ranging from $5,000 to $150,000). A significant safety upgrade was completed in 2019 with the installation of a modern fire alarm system, including wireless low-frequency sounders in sleeping areas to meet code requirements.

The building has experienced some recurring maintenance and safety issues over the years. Most recently, in July 2023, there were violations regarding fire escape ladder maintenance and compliance documentation, though these were abated by August 2023. Historical complaints from 2017 and 2012 indicate concerns about security, including mail theft and building access, as well as maintenance issues like elevator problems and heating system outages. There were also multiple past violations related to boiler operation permits in 2010-2005, though these are now marked as not active. The property has maintained active communication with city authorities regarding building maintenance and safety standards, as evidenced by various completed permits and inspections over the years. Recent 311 calls from 2022-2024 primarily relate to street-level issues such as waste removal and parking concerns, rather than building-specific problems.

Risk rating

How 16 Laguna 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 16.3%
Moderate concern 77.1%
Severe concern 6.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
