Jordan Park/Laurel Heights, SF 94118 1040038 24 units · 3 fl · 1970

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 340 Arguello Blvd 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 1970
2 or more units

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 1970
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

340 Arguello Blvd is a 24-unit, 3-story multi-family residential building constructed in 1970 and currently owned by Burnham Properties. The building has undergone significant recent renovations, including a bathroom and electrical panel upgrade in Unit 305 completed in March 2024 ($28,000), following a pattern of unit improvements since 2016 that included similar upgrades in Units 306, 206, and 106, typically involving kitchen and bathroom renovations with electrical panel relocations. A major fire safety upgrade was completed in 2022 with the installation of a new fire alarm system and low-frequency sounders. The building completed its mandatory soft-story retrofit in 2016, demonstrating compliance with seismic safety requirements.

The property has maintained regular plumbing and electrical infrastructure upgrades, including a main water line replacement in 2017 and a new hot water boiler installation in 2014. While there have been multiple 311 calls regarding the building and its vicinity, most relate to street maintenance and parking issues rather than building conditions. The building has experienced some fire alarm system activations due to malfunctions and false alarms, though with no civilian injuries reported. Historical routine inspections by Housing Inspection Services from 1996 through 2016 have been conducted, with no active complaints currently on file. All recent permits and improvements suggest active management of the property's maintenance and safety systems, with particular attention to updating individual units and essential building systems.

Risk rating

How 340 Arguello Blvd'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
4thpercentile

Out of 272 buildings in this neighborhood, 261 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

Number of units

Building size

Notices of Violation (past 7 years)

DBI issued Notices of Violation at this address over the last 7 years — a direct record of code enforcement activity.
