439 Guerrero St

Mission Dolores, SF 94110 3568057 3 units · 2 fl · 1909

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 439 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 before 1979
Built 1909
2 or more units

Property type
Multi-Family Residential

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1909
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 439 Guerrero Street is a 3-unit, 2-story multi-family residential building constructed in 1909, currently owned by Gary Allen Meade. The building has undergone significant improvements over the past decade, with the most recent work being a completed re-roofing project in December 2024 costing $18,000. Notable safety and security enhancements include the installation of window bars in 2023 (with emergency release mechanisms in bedroom windows) and the comprehensive upgrade of the fire safety system in 2011, which included a new fire alarm system, smoke detectors, and sprinkler system installation across all three units. The building has also received modern sustainable upgrades, including a solar panel installation in 2013 with multiple PV modules and inverters totaling 6.5 kW capacity.

The property underwent substantial renovations around 2009-2010, including complete plumbing upgrades with the installation of 10 bathrooms, 3 kitchens, multiple water heaters, and electrical system improvements featuring 400-amp service and hundreds of new fixtures. Historical records indicate that the building was converted from a church structure to its current residential configuration, with associated variance approvals for rear-yard and garage-door-width modifications. While there have been two building-related complaints (in 2004 and 2008) regarding unpermitted work and noise issues, both were promptly resolved. More recently, there have been multiple 311 calls in late 2024 regarding street cleaning and debris issues in the vicinity of the property, though these appear to be related to the surrounding area rather than the building itself.

Risk rating

How 439 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
55thpercentile

Out of 799 buildings in this neighborhood, 360 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
