Excelsior, SF 94112 6014038 3 units · 3 fl · 1923

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.

Rent & eviction protection

Is 4535-4537 Mission 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.

Built before 1979
Built 1923
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.

15+ years since occupancy
Built 1923
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 three-unit multi-family residential building at 4535-4537 Mission Street, located in the Excelsior neighborhood, was constructed in 1923 and is currently owned by the Cindy Diem Trinh Revocable Trust. The property has maintained its original flat and store configuration, with a three-story structure containing four units or fewer. Historical permit records show some maintenance activity in the 1990s, including a reroofing project in 1994 and removal of double doors in 1995, though these permits have since expired. A completed permit from 1984 indicates the installation of an electric sign on the property.

Recent history (2021-2025) reveals several maintenance and cleanliness challenges in the immediate vicinity. The building has experienced recurring issues with graffiti (notably documented in 2023 and 2022), and multiple incidents of street cleaning needs, including reports of human/animal waste and loose garbage in 2021 and 2024. There was a significant infrastructure incident in April 2024 involving a sewage backup. Parking-related concerns have been notable in recent years, with multiple reports of illegal parking, including double parking incidents in 2025 and 2024, though these are more reflective of street rather than building issues. A gas leak incident was recorded in 2010, though it resulted in no civilian injuries and appears to have been resolved promptly. The most recent building-related permits were for street space metered parking permits in 2019, suggesting ongoing parking management considerations in the area.

Risk rating

How 4535-4537 Mission 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
15thpercentile

Out of 337 buildings in this neighborhood, 286 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.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
