Why San Francisco Property Owners Choose DrBalcony for Section 604

DrBalcony handles all three in a single coordinated visit — delivering all required reports and the SF DBI affidavit together. One licensed civil engineering firm. In-house PE stamp.

Federally Patented — DrBalcony

Our patents cover a system that locates framing joists from outside the structure, drills a single small-bore hole per framing cavity, passes a borescope camera inside to photograph structural wood condition, and seals the patch. No membrane demolition. No deck removal. No unnecessary exploratory damage. Targeted findings drive targeted repairs — Section 604 San Francisco property owners pay only for what is actually deteriorated.

⚠️ San Francisco HOA & Condo Boards: Verify Section 604 & SB-326 Inspector Credentials

California Civil Code §5551 (SB-326) requires only a licensed structural engineer, civil engineer, or architect to sign a condominium or HOA inspection report. Section 604 requires a licensed inspector. Before contracting any vendor for a San Francisco HOA or residential building, request the signing engineer’s California PE license number and verify it at dca.ca.gov. DrBalcony’s in-house licensed PE signs every Section 604, SB-721, and SB-326 report directly.

FAQ

Section 604 Inspection San Francisco — Frequently Asked Questions

Common questions about Section 604 Inspection San Francisco, SB-721, SB-326, EEE inspection, E3 inspection, and California compliance requirements.

Section 604 of the San Francisco Housing Code requires all residential buildings with exterior attachments — balconies, decks, stairways, walkways, landings — to be inspected every 5 years by a licensed professional. An affidavit confirming the inspection must be filed with SF DBI. Applies to all SF residential buildings including single-family homes, duplexes, apartments, and condos.
All San Francisco residential buildings with exterior attachments must comply with Section 604 every 5 years, regardless of building size or unit count. This is broader than SB-721 and SB-326. If your SF building has any exterior balcony, deck, stairway, walkway, or landing, Section 604 applies.
No. These are three separate requirements. Section 604 is a San Francisco-specific local ordinance requiring balcony and deck inspection every 5 years with a DBI affidavit. SB-721 is California state law for rental buildings with 3+ units, required every 6 years. SB-326 is state law for HOAs and condos, required every 9 years. San Francisco property owners may need to comply with all three simultaneously.
The Section 604 affidavit is a signed declaration by a licensed inspector confirming that exterior attachments have been inspected and are either (a) in safe condition, or (b) have identified conditions requiring repair within a specified timeframe. DrBalcony prepares and assists with filing the affidavit as part of every Section 604 inspection.
Yes — and that’s exactly what we recommend for San Francisco properties. DrBalcony coordinates all three inspections in a single on-site visit when possible, delivering all required reports and the DBI affidavit together. More efficient and cost-effective than separate inspections.
Non-compliance can result in SF DBI notices of violation, daily fines, required repairs under city enforcement, and legal liability in personal injury cases. Combined with SB-721 and SB-326 penalties, San Francisco property owners face the most complex balcony and EEE inspection compliance environment in California.

“San Francisco property owners face three separate inspection laws simultaneously. DrBalcony is the only firm that coordinates Section 604, SB-721, and SB-326 in a single visit — with one PE stamp, one report package, and one DBI affidavit.”
