Pilot · demoCommunity associations
For HOA boards and management companies
Available now as a founding pilot. One subscription covers VendorGuard, HOA Docs AI and the balcony inspection tracker; the coverage review is an optional add-on.
VendorGuard CA
Reads vendor certificates of insurance, compares them with each association's requirements, re-checks CSLB license, bond and workers' comp every night against CSLB's public data (file date shown), and reminds vendors until they comply.
HOA Docs AI
Cited answers from the association's CC&Rs, bylaws, rules, budget and minutes, for the board, the manager and, through one private link, every owner.
Balcony inspections (SB 326)
Tracks each building's exterior elevated element inspection deadline under Civil Code 5551, records the inspector's report and findings, and keeps repair targets and reminders in one place. It tracks dates and documents; it doesn't inspect buildings.
How it works · Live demo (choose Balconies)
HOA Coverage Review
A written review of the master policy against the CC&Rs, the reserve study and current rebuild costs, pointing out possible underinsurance, gaps and deductible exposure to discuss with the broker. Informational, for the board and its broker.
VendorGuard, HOA Docs AI and the balcony tracker are included in every plan. First five pilot customers get 60 days free. Full pricing
Apartment and commercial buildings
For apartment owners and property managers
Starting with the SB 721 balcony inspection rules for buildings with three or more units. More commercial property tools are coming.
Balcony inspections (SB 721)
Tracks each building's inspection deadline under Health & Safety Code 17973, records the inspector's report and findings, and shows the 120-day permit and 120-day repair clocks with reminders. Checks SB 721 inspectors' CSLB license status. It tracks dates and documents; it isn't engineering or legal advice.

For California homeowners rebuilding after a disaster
Self-serve record keeping for a rebuild, for families rebuilding after the 2025 Eaton and Palisades fires or any California disaster.

About
Built by a California property insurance claims professional
Caissonix was founded by Gregor McNabb, who has spent nearly 20 years in California property claims and holds an M.S. in Construction Management. Too often the problem after a loss isn't the loss itself: it's a vendor whose insurance had lapsed, a rule nobody could find, or a policy that didn't match what the association needed.
Caissonix exists to catch those issues early, with software that does the routine checking and reviews written in plain language a volunteer board can use.
We don't sell, place or broker insurance, and we don't give legal advice. Our tools and reviews give you a clear picture to take to your broker, attorney and board.
