Multi-Tenant From Scratch · Three-Role Permission System · End-to-End Workflows
A founder needed a property management SaaS built from the ground up — one that could onboard multiple property management organisations, each with completely isolated data, while giving admins, landlords, and tenants exactly the access their role required.
We built the full multi-tenant SaaS architecture — clean data isolation between organisations, a three-role permission system, and complete property and tenant management workflows from listing through lease to maintenance requests.
Building a SaaS product from zero that will serve multiple independent organisations means the foundational architecture decisions have to be right before a single customer signs up.
This was a greenfield build — there was no legacy codebase to extend, which meant every architectural decision about tenancy, roles, and data boundaries had to be made correctly from day one.
Each property management organisation needed complete confidence that another organisation could never see their properties, tenants, or financial data — a single shared-schema mistake here is a trust-ending bug.
Admins, landlords, and tenants each needed a genuinely different experience of the same platform — not the same dashboard with a few links hidden.
A property management platform that only handles listings but not leases, or leases but not maintenance requests, doesn't replace what a property manager actually needs day to day.
We architected the platform as multi-tenant from the first migration — every property, lease, and maintenance record is scoped to an organisation at the data layer, not just filtered in application code.
The founder can bring on a new property management company as a customer without needing a code change or manual database setup for each one.
Admins, landlords, and tenants each work in a dashboard scoped to their actual responsibilities — nobody sees a generic interface with irrelevant options.
Because tenant scoping happens at the query layer, there is no scenario where a developer adds a new feature and accidentally leaks data across organisations.
From listing a unit to resolving a maintenance request, the entire lifecycle lives in one system — not spread across a property management tool, a spreadsheet, and email.
Organisation scoping is implemented as a global query constraint on every tenant-owned model, not as a convention developers have to remember to apply manually. A query that forgets to scope by organisation simply cannot happen.
Permissions aren't just "landlord can do X" — they're scoped to the specific properties and units a landlord owns, and the specific unit a tenant leases. This ownership-aware permission model is what keeps the same three roles working correctly regardless of organisation size.
Every part of the system that varies per organisation — branding details, lease terms, maintenance categories — is configuration, not code. Adding a new organisation is a data operation, never a deployment.
