Rent & eviction protection

Is 3750-3752 16Th 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.

15+ years since occupancy
Built 1906
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 property at 3750 16th Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by 606804 Ontario Limited. The building has undergone several significant repairs and improvements over its lifetime, most notably a major renovation in 1986 that included the addition of a garage, a penthouse "lantern," and remodeling of kitchens and bathrooms. The most recent permitted work, in April 2024, involves the installation of a wood retrofit window on the street-facing side of the building, with a reported cost of $4,494.

The property has experienced recurring sewer-related issues, with multiple incidents reported between 2019 and 2021, including sewage backups and a sewer vent problem documented in September 2021, which required approximately 8 feet of spot repair work on the sewer main with house trap. This pattern of sewer problems, though somewhat resolved, suggests an ongoing infrastructure challenge. Noteworthy recent events include three reports of pavement-related issues in late 2023 and 2024, although these were primarily parking enforcement matters rather than building-related concerns. The building's maintenance history shows attention to structural updates, particularly in recent years, with the installation of new windows and the 2021 sewer repairs representing significant infrastructure improvements. The property has also experienced several instances of abandoned vehicles in the vicinity between 2018 and 2024, though these external issues do not directly impact the building's condition or resident experience.

Risk rating

How 3750-3752 16Th 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.

Neighborhood (ZIP code)

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

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 70.5%
Moderate concern 16.4%
Severe concern 13.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
