Rent & eviction protection

Is 494 36Th Ave 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 1928
2 or more units

Property type

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.

15+ years since occupancy
Built 1928
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 494 36th Avenue in the Outer Richmond district is a two-story, four-unit multi-family residential building constructed in 1928, currently owned by Victoria T & William J Ng R. The building has undergone several significant renovations and faced various compliance issues over the years. Most recently, in September 2024, a complaint was filed regarding the illegal paving of greenery in front of the building, allegedly violating SF green ordinances; this issue was quickly addressed within two days. The property has an active permit filed in March 2019 for substantial alterations to convert the lower level unit, including adding a bedroom, bathroom, kitchenette, and more, though planning records indicate additional review was needed for window modifications and excavation work.

In 2003, the building faced multiple fire safety violations, including issues with smoke detectors, fire proofing, combustible storage, and fire escape maintenance, all of which were resolved by May 2003. A similar situation occurred in 1997 with unauthorized basement unit construction, though that was also resolved within months. The building's maintenance history shows various infrastructure work, including reroofing in 2005 and dry rot repairs in 1997. More recently, the property has experienced several street-level maintenance issues, as evidenced by multiple 311 calls between late 2024 and early 2025, primarily regarding garbage and debris concerns, though these seem to be related to street management rather than building-specific issues. While the building has had its share of compliance issues and necessary repairs over the years, all recorded violations have been addressed, and no active violations are currently on record.

Risk rating

How 494 36Th Ave'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
27thpercentile

Out of 1040 buildings in this neighborhood, 759 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

Neighborhood location

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