What You Need to Know About SF604 Inspections: Requirements, Compliance, and Common Issues

If you own or manage a multi-unit residential building in San Francisco, compliance with Section 604 of the San Francisco Housing Code is not optional - it’s a legal requirement. These mandatory inspections are designed to ensure the safety and structural integrity of Exterior Elevated Elements (EEEs) such as balconies, decks, stairs, landings, and walkways.
 

Buildings with three or more residential units must undergo a Section 604 inspection every five years, with a signed affidavit submitted to the San Francisco Department of Building Inspection (DBI) confirming the condition and compliance of these components. Failing to comply can lead to fines, violations, or even legal action.
 

What Does a Section 604 Inspection Include?

A Section 604 inspection is a detailed evaluation of all EEEs six feet or more above ground and supported in whole or in part by wood or wood-based products. These components are particularly vulnerable to damage from weather, moisture, and everyday wear.
 

Structural Integrity

Inspectors check for visible signs of damage, rot, sagging, rust, or warping in joists, beams, posts, and any other structural supports. Special attention is given to wood-to-wood and wood-to-concrete connections, which are prone to deterioration.
 

Railings and Guardrails

Railings must meet current height and stability requirements. Inspectors look for wobbling, corrosion, and fastener failure. A railing that doesn’t meet the minimum 42-inch height or is not securely anchored will be marked for correction.
 

Fasteners and Connectors

All bolts, nails, brackets, and hardware are checked for corrosion, loosening, and failure. These small components are critical to structural integrity and are often the first to degrade in San Francisco’s coastal climate.
 

Deck and Balcony Surfaces

Decking boards and balcony floors are inspected for cracking, splintering, warping, and signs of rot. Surfaces must be strong enough to support regular occupancy and any furnishings typically placed outdoors.
 

Waterproofing Systems

Effective waterproofing is essential to prevent moisture intrusion, which can lead to rot, mold, and decay. Inspectors examine the condition of flashing, sealants, membranes, and coatings, checking for peeling, bubbling, or other signs of failure.
 

Drainage and Moisture Control

Proper drainage is critical in preventing water from pooling on EEEs. Inspectors ensure water is being directed away from structural components and that downspouts, scuppers, and weep holes are functioning correctly.
 

Pest Damage

Wood-destroying organisms like termites and carpenter ants can significantly weaken EEEs. Signs of infestations, such as hollowed wood or mud tubes, will be noted during inspection.
 

Why Section 604 Compliance Matters in San Francisco

The unique climate of San Francisco, with its high humidity, fog, and salt air, creates conditions that accelerate the wear and deterioration of wooden and metal structural elements. This makes Section 604 inspections especially important in the region.
 

Neglecting these inspections can result in:

• Code violations and city enforcement actions

• Increased liability in the event of accidents or injuries

• Higher repair costs due to unchecked damage

• Difficulty with insurance coverage or refinancing

Beyond legal compliance, these inspections protect residents and help maintain property value by ensuring the continued safety and reliability of exterior structures.
 

What Happens If You Fail the Inspection?

Failing to pass a Section 604 inspection does not necessarily mean your building is unsafe, but it does trigger the need for prompt action:

• Identify and prioritize safety-related repairs, especially anything that poses an immediate hazard.

• Work with licensed contractors familiar with local codes to perform necessary remediation.

• Keep thorough documentation of before-and-after photos, repair invoices, and contractor licenses.

• Schedule a follow-up inspection to confirm compliance and file your affidavit with the city.
