Rent & eviction protection

Is 684-688 Guerrero 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 1908

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 property at 684-688 Guerrero Street is a 6-unit, 3-story multi-family residential building constructed in 1908, currently owned by Michael James Spaulding. The building has undergone significant improvements over recent years, including a completed soft-story retrofit in 2021 (with a CFC issued) that addressed seismic safety concerns, and substantial renovations to multiple units. Most notably, Unit 688 is currently undergoing extensive remodeling in 2024, including a kitchen remodel, addition of a second bathroom, window replacements, and electrical rewiring, with permits totaling over $240,000. Similar improvements have been made to Unit 2 (2nd floor) in 2022, including kitchen and laundry room renovations. The building's maintenance record shows proactive upkeep, with ongoing work including re-roofing (2024) and structural improvements to a rear stair footing.

However, there are several concerning issues that require attention. There is an active complaint from 2019 (case #201979951) with multiple violations including fire safety concerns, egress obstruction, missing smoke and carbon monoxide detectors, and issues with exterior door self-closing devices, railings, fire escape maintenance, and sanitation. These violations, while filed in 2019, appear to remain unresolved. Additionally, there have been multiple recent complaints (2023-2024) regarding unauthorized construction work and potential permit violations. A recent complaint from October 2024 alleges improper installation of patio lights affecting a neighboring property. The building has received multiple service requests for public space maintenance near the property, including reports of waste and debris on adjacent streets and sidewalks throughout 2023-2024, though these external issues are being addressed promptly by city services.

Risk rating

How 684-688 Guerrero 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
5thpercentile

Out of 799 buildings in this neighborhood, 759 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
