Rent & eviction protection

Is 4010 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 before 1979
Built 1959
2 or more units
6 units
Property type
Multi-Family Residential
Zoning
RH2
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 1959
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, six-unit multi-family residential building at 4010 Mission Street in Bernal Heights, owned by Nicholas J & Carole A Genna and constructed in 1959, has undergone several significant safety and modernization improvements in recent years. Most notably, in 2023, the building received a major upgrade to its fire alarm system to comply with current fire code requirements, and in 2017-2018 completed mandatory seismic retrofitting as a Tier 3 soft-story building with a Certificate of Final Completion issued. Unit 1 received significant renovations in 2021, including kitchen and bathroom remodeling, with proper permits obtained for the work.

The building has a history of maintenance and compliance efforts, including completed reroofing in 1993, and previous kitchen and bathroom renovations in 2008 (though initially without proper permits). Multiple violations and complaints were recorded between 2005-2015, primarily related to building safety and maintenance issues including ventilation problems, egress obstructions, fire escape maintenance, and unauthorized construction work. However, all these violations have been marked as "Not active" and were abated. The most recent building-related concerns appear to have been resolved, with the last building inspection-related complaint dating back to 2015. Street cleaning records from 2020-2023 show regular monitoring of the building's immediate vicinity, though these are general municipal service calls rather than building-specific issues. The property has demonstrated ongoing commitment to safety and compliance through regular maintenance and prompt attention to regulatory requirements, particularly evidenced by the recent fire alarm system upgrade and seismic retrofit completion.

Risk rating

How 4010 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

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
14thpercentile

Out of 1276 buildings in this neighborhood, 1097 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.

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
