Outer Sunset, SF 94122 1793046 4 units · 2 fl · 1948

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 3731 Irving 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 1948

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.

Built 1948
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

Located in San Francisco's Outer Sunset neighborhood, 3731 Irving Street is a two-story, four-unit multi-family residential building constructed in 1948, currently owned by Xiao Tong & Chuck Tai Wong. The property has undergone several significant improvements over its lifetime, including a reroofing project in 2021 costing $18,000, installation of additional storage for lower and upper units in 2001, and completion of essential repairs including dry rot remediation at the base of stairs and window replacement in 1986. Historical records show the building has maintained compliance with building codes, as evidenced by a 1984 permit specifically for code compliance, though a reroofing permit from 1996 is listed as expired.

The property experienced a notable complaint in 2014 regarding a possible illegal in-law unit housing over ten people, though this case is currently marked as not active. Three routine housing inspections were conducted between 2000 and 2002, with all issues resolved. The building has been the subject of multiple parking-related incidents in recent years, particularly between 2019 and 2023, with numerous cases of driveway blocking leading to citations, though some were resolved without enforcement action. A routine issue with parking violations was partially addressed in 2020, and there was one report of an abandoned motorcycle in 2019 that was resolved when the vehicle was no longer present. The consistent pattern of parking enforcement actions suggests ongoing challenges with vehicular access to the property, though these incidents are primarily external to the building itself and relate to street parking enforcement.

Risk rating

How 3731 Irving 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
30thpercentile

Out of 632 buildings in this neighborhood, 442 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

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

Neighborhood location

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
