Parcel, plan, and preliminary fit
Understand what a planning tool can clarify—and what still requires verification.
Official guidance on plans, consultants, and site-specific information for a permit application: LA County — Prepare Plans (reviewed October 7, 2026).
A useful early fit study connects a verified parcel snapshot, buildable constraints, household program, a selected plan or module arrangement, and current rate assumptions. Changing one input can change the result.
What to ask for in an early fit study
Ask ROAM which tools and deliverables are available for your agreed scope. These are planning goals; availability to an invited user must be confirmed individually.
- Preserve the parcel, rule, plan, module, and rate versions used for a result.
- Show why a plan may fit, conflict, or require a different arrangement.
- Compare program and preliminary range tradeoffs before deeper drawing work.
What it cannot replace
- A current survey, title or easement review, geotechnical or engineering work.
- Agency interpretation, permit approval, contractor pricing, or a construction contract.
- Professional judgment about a specific property and household.
