Rent & eviction protection

Is 431-437 Spruce 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 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 4-unit, 2-story multi-family residential building at 431-437 Spruce Street in Presidio Heights, owned by the Tjoe Family Trust, has undergone several significant renovations since its construction in 1900. The most recent major work was completed in 2016, involving comprehensive remodeling of one bathroom, a half bathroom, and kitchen, along with window replacements, electrical upgrades, and unit-wide painting, costing $25,000. Prior improvements include a 2011 renovation of one kitchen and one bathroom, a porch sheetrock installation in 2008, and a reroofing project in 2007. The building received multiple system upgrades between 2006-2008, including electrical work for lighting and emergency systems, plumbing updates for all units, and an underground service conversion.

Of particular note, the building experienced a series of violations in March 2008 related to safety and maintenance issues, including concerns about lead paint hazards, security deficiencies (such as missing door viewers), fire safety equipment, and exterior paint conditions. However, all these violations were officially abated by April 17, 2008. The property has maintained regular maintenance and upgrades over the years, with several units receiving targeted improvements (e.g., Unit 433's kitchen improvements in 2007). Recent activity includes routine inspections and standard municipal service requests, such as temporary parking signs and street maintenance issues, though these are not directly related to the building's condition or management.

Risk rating

How 431-437 Spruce 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
53rdpercentile

Out of 181 buildings in this neighborhood, 85 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 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.
