Rent & eviction protection

Is 1748-1750 Filbert 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.

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 1908
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 property at 1748-1750 Filbert Street is a three-story multi-family residential building constructed in 1908, currently owned by John & Lisa Vigo Revocable Living Trust. This address underwent significant improvements between 2018-2020, including the addition of an ADU (Accessory Dwelling Unit) to the rear building, completed with comprehensive fire sprinkler systems, new electrical, plumbing, and mechanical work. The project, which added 812 square feet of living space plus mechanical areas, was valued at $150,000 and included safety enhancements such as a new residential fire sprinkler system costing $10,374. Other major improvements during this period included foundation repairs ($45,000) and various infrastructure upgrades to modernize the building's systems.

The property's maintenance record shows attention to safety and compliance, with past plumbing work including waste & vent pipe replacements, electrical system upgrades, and solar preparation installations completed in 2009. The building has maintained active compliance with building codes, though there is a historical housing complaint from 1997 regarding inadequate heating that remains listed as active without resolution noted in the records. Recent activity at the property has primarily involved parking enforcement issues, with multiple citations issued for driveway blocking between 2024-2025, though these are not directly related to the building's condition or habitability. The most recent permitted work focuses on ensuring the ADU addition meets current safety standards, with various permits showing completion of necessary infrastructure changes to support the additional unit while maintaining the existing structure's integrity.

Risk rating

How 1748-1750 Filbert 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
55thpercentile

Out of 861 buildings in this neighborhood, 387 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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