Rent & eviction protection

Is 421 14Th Ave 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 1927
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 1927
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 6-unit, 3-story apartment building at 421 14th Ave in the Central Richmond neighborhood was constructed in 1927 and has undergone several significant improvements over the years. Most notably, the building completed its mandatory soft-story retrofit in 2014 (at a cost of $95,000), demonstrating commitment to seismic safety. A recent important upgrade was the fire alarm system replacement completed in 2022 ($15,000) to meet current safety standards. The property has seen consistent maintenance and improvements, including bathroom remodels in units 2 and 5 (2017), vinyl siding installation (2002-2003), and foundation work (1988).

The building has maintained an active response to violations and safety concerns, with all known violations from a 2002 housing inspection being promptly addressed within two months. These violations included issues with lead paint, fire escape maintenance, and various interior surface problems, all of which were abated by August 2002. More recent records show regular maintenance and infrastructure updates, including sewer repairs (2018) and various plumbing and electrical improvements. Although there have been some neighborhood concerns documented through 311 calls in recent years (2020-2024), these are primarily related to street conditions and public space issues rather than building-specific problems. The property has experienced two minor fire-related incidents recorded as "Assist invalid" and "Public service," with no civilian injuries reported in either case.

Risk rating

How 421 14Th Ave'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
16thpercentile

Out of 2250 buildings in this neighborhood, 1890 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 size

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

Owner's portfolio size

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