Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. 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 677 48Th 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 1959
2 or more units

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 multi-family residential building at 677 48th Avenue in San Francisco's Outer Richmond district, owned by the Marylyn L Saucer 1988 Trust, is a 3-story, 6-unit apartment building constructed in 1959. The building has undergone several significant structural improvements over the past two decades, most notably completing a mandatory soft-story retrofit in 2017 at a cost of $52,600, which was required for Tier 3 buildings. Recent maintenance work has included multiple deck and balcony repairs in 2024, addressing dry rot issues in units 2, 4, and 6, as well as repairs to unit 5's balcony joists, demonstrating ongoing attention to building maintenance and safety.

Historical records show a pattern of proactive maintenance and upgrades, including reroofing in 2023 ($22,568), rear stair replacement in 2016 ($10,000), and water main line replacement in 2019. The building has experienced some building violations and complaints, particularly in 2006 when multiple issues were identified related to deck repairs, stair repairs, and fire safety concerns, though all were subsequently resolved. Recent 311 calls from 2022-2023 have primarily involved external issues such as toter management, sewage concerns, and graffiti, rather than building structural or safety problems. The property has maintained compliance with safety regulations, having completed required inspections and obtained necessary permits for various improvements, including electrical upgrades with meter relocation in 2008 and multiple plumbing improvements.

Risk rating

How 677 48Th 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
13thpercentile

Out of 1040 buildings in this neighborhood, 905 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.

Neighborhood location

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Owner's portfolio size

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