Rent & eviction protection

Is 4623-4625 Anza 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.

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.

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 at 4623-4625 Anza Street is a four-story multi-family residential building constructed in 1946, containing two units. The building has undergone significant improvements over the past decade, most notably the installation of a comprehensive fire sprinkler system in 2012-2013, which included 80 heads and underground components, costing approximately $40,000. In 2012, substantial modifications were made including basement excavation work with shoring costing $125,000, followed by extensive plumbing renovations in 2012-2013 that involved installing new bathrooms, kitchens, gas mains, condensing boilers, storage tanks, and radiant pex pipe systems.

The building's renovation period saw multiple complaints in 2012-2013 regarding potential unauthorized work and height concerns, though these complaints were marked as not active. Electrical upgrades were completed in 2013 with a complete rewire and Ufer ground installation. While the property has experienced recurring issues with driveway blocking, as evidenced by multiple parking enforcement calls between 2018 and 2023, these incidents are not directly related to the building's structural or safety features. Recent building permits issued in 2013-2014 primarily concerned street space usage. A proposal for a rear yard variance to construct a three-story addition was submitted by developer David Armour, but records indicate this was eventually withdrawn or closed.

Risk rating

How 4623-4625 Anza 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
52ndpercentile

Out of 1040 buildings in this neighborhood, 499 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.

Building size

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

Neighborhood location

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

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.
