Rent & eviction protection

Is 3630 Market 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
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.

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 two-story multi-family residential building at 3630 Market Street in Twin Peaks, owned by William C Roberts, is a three-unit apartment structure dating back to 1900. The building's maintenance record shows limited significant work, with only one major building permit on record - an $18,000 reroofing project from 2001, though this permit has since expired.

More recent activity has been concentrated on street-level issues in the immediate vicinity of the property rather than the building itself. Since mid-2024, there has been a notable pattern of parking-related incidents, with multiple citations issued for driveway blocking, culminating in five such incidents between August and October 2024. There have also been recurring issues with graffiti (two instances reported in January 2025), street cleaning concerns including garbage and debris (August 2024), and one instance of a burnt-out streetlight (August 2024). The most recent documented issues as of 2025 include unresolved graffiti cases from January 2025 and a sidewalk parking complaint that could not be verified by responding officers. The frequency of parking enforcement calls, particularly during August 2024 when three citations were issued for driveway blocking, stands out as the most significant pattern in the building's recent history, though these are more indicative of neighborhood conditions than building-specific issues.

Risk rating

How 3630 Market 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
58thpercentile

Out of 172 buildings in this neighborhood, 72 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.

Neighborhood location

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

Estimated permit spend (past 7 years)

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

Building age

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