Rent & eviction protection

Is 3933 Mission 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 1951

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 1951
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 underwent significant renovations in 2018-2019, including the addition of two dwelling units at the ground floor, seismic strengthening, and comprehensive fire safety upgrades. The extensive renovation work included the installation of a new fire sprinkler system throughout the building, an upgraded fire alarm system with sprinkler monitoring and low-frequency sounders, new plumbing and radiant heating systems, and electrical upgrades including a new 400-amp service with sub-panels for each unit. The building's modernization efforts, valued at over $600,000, improved both safety and livability standards.

The property has a history of addressing maintenance and safety compliance issues, with several routine inspections and violations documented between 2001 and 2015. Notable past concerns included fire safety equipment requirements and lead paint notification, all of which were subsequently addressed and abated. During the recent renovation period in early 2019, there were some resident complaints about construction noise and dust, which were documented through 311 calls and building complaints. Recent maintenance records, including 311 calls and permits, indicate that the property is actively managed and that major systems have been upgraded to meet current safety standards. The building's recent improvements focus on fire safety, seismic stability, and unit modernization, suggesting a significant investment in maintaining and upgrading the property for current and future tenants.

Risk rating

How 3933 Mission 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 1276 buildings in this neighborhood, 1046 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 44.6%
Moderate concern 23.0%
Severe concern 32.4%
