Rent & eviction protection

Is 607-609 Hayes 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 1900

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 1900
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-story, two-unit residential building at 607-609 Hayes Street in Hayes Valley, owned by Luke Lian Sung Living Trust, has experienced several significant events over the past several years. Most notably, in October 2024, there was a complaint about unauthorized heavy construction work, which was promptly investigated by the Building Inspection Division. Subsequently, two legitimate building permits were issued and completed: one for the installation of an indirect floor drain in a commercial kitchen (February 2025), and another for replacing non-visible rear siding (October 2024). The property has also been the subject of various 311 service requests in 2026, including investigations into blocked parking spaces, garbage and debris issues, and encampment reports, though most were resolved promptly with no significant findings, except for one garbage complaint in October that involved human waste or urine.

The building's documented history shows regular maintenance and improvements, with three building permits issued over seven years totaling approximately $4,750 in construction costs. The most recent construction activity appears to have been properly permitted following an initial complaint about unauthorized work. While the property has had some sanitation and encampment-related service requests in 2026, these issues seem to have been addressed promptly through city services. The relatively low number of building permits and complaints over the past seven years suggests generally stable building conditions, though the recent construction activities indicate ongoing maintenance or improvement efforts.

Risk rating

How 607-609 Hayes 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.

Neighborhood percentile

Out of 1027 buildings in this neighborhood, 41 are predicted to be safer.

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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 87.2%
Moderate concern 7.6%
Severe concern 5.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
