North American ADU pre-construction OS

Make backyard housing feasible, financeable, and buildable.

ADUflow starts where North American projects get stuck: zoning, permit risk, factory vs site cost, and lender confidence. Then it turns the project into a quote-ready package.

Strategic wedge

North America needs feasibility before configuration.

PZZL begins with product configuration. ADUflow should begin with local rules, parcel constraints, HOA friction, lender evidence, and the prefab supply chain.

01

Zoning feasibility

Screen lot type, setbacks, review risk, and likely ADU envelope before design starts.

02

Prefab scope

Separate factory cost from site cost so builders, buyers, and lenders see the real budget.

03

Bankable build

Package permit tasks, BOMs, draw milestones, and progress verification for financing.

For ADU and prefab builders

A guided pilot for reducing dead-end ADU leads.

ADUflow is ready for builder conversations as a pilot workflow: address-first feasibility, catalog-based pricing, proposal, lender package, permit tracker, and draw log.

Qualify faster

Turn an address into a first-pass feasibility package before your estimator spends hours on a cold lead.

Quote consistently

Use your active models, option pricing, credentials, and service region to keep every proposal aligned with your business.

Support financing

Generate a lender-oriented package with scope, budget split, draw schedule, evidence needs, and builder credentials.

GIS and parcel rules

Address-based zoning, envelope, setback, height, parking, and servicing checks.

Prefab marketplace

Factory modules, panelized systems, transport assumptions, and site install packages.

Permit assistant

Municipal submittal checklists, HOA review packs, and revision tracking.

Draw verification

Photo-based milestone evidence for lenders, builders, and homeowners.

Pilot boundaries

What to say clearly in every builder demo.

Zoning results are first-pass screens, not permit approvals.Fallback data must be reviewed by the builder before customer commitments.Pilot login is builder-scoped for demos; production auth is the next hardening step.
