Create a jurisdiction-specific permit matrix before committing to land, plans, or a factory slot.
Approval depends on the specific parcel, use, design, foundation, utility plan, and local review process. A verbal statement about modular construction does not establish that a particular project can be built or occupied.
Identify every authority with a decision
Start with the parcel number and legal jurisdiction, then identify planning, zoning, building, fire, health, public works, utilities, transportation, environmental, and design-review authorities. Private covenants, easements, road agreements, and architectural controls can add separate obligations even when public zoning permits the use.
Ask parcel-specific questions in writing
- Is the proposed dwelling use allowed in this district?
- Which setbacks, height, size, frontage, parking, and access rules apply?
- Is modular construction reviewed differently from other code-compliant construction?
- Which site plan, engineering, energy, utility, and drainage documents are required?
- What must be approved before foundation work, production, delivery, and occupancy?
- Which fees, hearings, expiration dates, and appeal paths apply?
Separate approvals by what they control
| Approval layer | What it answers | Evidence to retain |
|---|---|---|
| Land use | Whether and where the use may occur | Written determination, conditions, or approved site plan |
| Building | Whether design and construction meet applicable code | Approved plans, permit card, inspection record |
| Service and occupancy | Whether utilities, access, and final conditions are accepted | Connection approvals and occupancy document |
Build the approval sequence
- Confirm jurisdiction and parcel identity.
- Describe the system without marketing shorthand.
- Request the current submittal checklist and fee schedule.
- Log dependencies and concurrent reviews.
- Assign who answers each review comment.
- Track conditions through final inspection and occupancy.
Watch for false green lights
- Relying on a neighboring project with different zoning or date
- Confusing a planning answer with building approval
- Assuming factory engineering covers site and foundation design
- Ignoring private restrictions or legal-access requirements
Maintain one conditions register
Record each authority, contact, submission, decision, condition, expiration date, responsible person, and proof of closeout. Link every condition to the plan sheet, contract scope, inspection, or operational handoff that satisfies it. This prevents an approval note from disappearing between design, factory, and site teams.
