Rent & eviction protection

Is 510 Parker 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 1975

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.

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 multi-family residential building at 510 Parker Avenue, owned by the Matsouka Family Living Trust, has undergone several significant safety and maintenance upgrades since its construction in 1975. Most recently, in 2024, the building completed a major fire alarm system upgrade costing $28,200 to comply with current fire code requirements, including the installation of low-frequency sounders in sleeping areas and updating all existing devices. Earlier in 2024, the property received a new roof through a $29,900 project. The building has demonstrated commitment to seismic safety, completing a mandatory soft-story retrofit in 2016 at a cost of $50,000, which included the installation of a moment frame and shear wall for improved lateral stability.

Historical maintenance records show attention to various building systems and structures, including a 2015 electrical upgrade that relocated interior sub-panels from unit closets to hallway walls for improved access and safety. The property has experienced some code enforcement activity, particularly in 2003 and 2011, when violations were recorded regarding fire safety systems and building maintenance, though all these issues were promptly abated. Recent incidents primarily consist of recurring issues with street garbage management, with numerous notifications in late 2024 regarding overflowing city garbage cans. The building has a documented record of false fire alarms and system malfunctions, though no actual fire incidents or civilian injuries have been recorded. The property's fire safety systems have received regular attention, culminating in the recent comprehensive upgrade which addresses many previous concerns, including improvements to fire escape access and detection systems.

Risk rating

How 510 Parker 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
67thpercentile

Out of 519 buildings in this neighborhood, 171 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

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