Rent & eviction protection

Is 3631-3633 Buchanan 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 1954
2 or more units

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 1954
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 two-unit residential building at 3631-3633 Buchanan Street in the Marina district, owned by Robert Erick Pecha, was constructed in 1954 and has undergone several significant renovations over the past decades. Most notably, recent improvements include a completed reroofing project in 2024 costing $10,500, which followed substantial electrical upgrades in 2014 that included a service panel upgrade from 60 to 100 amps, installation of various appliances, and extensive electrical infrastructure work. The building received major interior renovations in 2013-2014, including kitchen and bathroom remodels with new fixtures, cabinets, and comprehensive electrical upgrades.

The property has experienced recurring fire safety concerns, with multiple fire code violations documented between 2018 and 2024, including issues with alarm systems, exit maintenance, and extinguishers, though many were corrected promptly or found to have no merit upon inspection. There have been several fire-related incidents recorded, primarily involving detector activations and one minor chimney fire, but no civilian injuries were reported in any incidents. The building's fire safety equipment and maintenance history shows a pattern of violations requiring attention, with the most recent documented violation in October 2024 related to ERRCS permits. Recent neighborhood issues noted in 2024-2025 include multiple reports of debris and waste removal needs in the vicinity of the property, though these are external to the building itself. The property has maintained compliance with major systems upgrades, including comprehensive electrical, plumbing, and fire safety improvements, though the pattern of fire code violations suggests ongoing attention to safety systems requirements has been necessary.

Risk rating

How 3631-3633 Buchanan 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
96thpercentile

Out of 988 buildings in this neighborhood, 40 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
