Written scope and price
Once the scope and selections are agreed in writing, the agreed work is not repriced without a documented change. Owner-requested changes and concealed conditions are explained before changed work proceeds.

How to read the range
A property review turns this range into a project-specific scope. The written scope, selections, allowances and exclusions are what make the final number comparable.
If an owner change or concealed condition affects cost or timing, it should be described in writing and approved before changed work proceeds.

Short answer. Use parcel zoning, easements, access, utilities and site-plan dimensions as bid inputs, then sequence building plans and trade pricing after the city confirms a complete submittal path.
| Median year built | 1972 |
|---|---|
| Homes built before 1980 | 61% |
| Homes built in 2000 or later | 22% |
| Median home value | $217,400 |
| Owner-occupied homes | 66% |
About 22% of Troy's 11,733 housing units, roughly 2,590 homes, were built in 2000 or later. That share of recent construction is the 4th highest of the 12 communities we serve. Because this city combines older streets and newer subdivisions, a new-build lot can be an infill parcel or part of a planned development. Each follows different rules for setbacks, architecture and utilities. Identify which applies, then confirm the survey, zoning and approvals before the price and schedule are set.

Troy's new-construction checklist requires a scaled site plan and states that required documents must be complete before approval.
Miami County says rough and final plumbing both need health department approval before the corresponding building inspections, so a new home has two plumbing sign-offs that gate the build.

The initial scope should identify the site conditions, survey and soil assumptions, foundation, structure, envelope, utility connections, mechanical systems, finishes, allowances and the documents each trade is pricing. Vague allowances at the start tend to become schedule and cost changes later.
Ground-up work moves through site preparation, foundation, framing, rough systems, inspections, enclosure, finishes and closeout. The schedule should show which approvals release the next stage and who owns corrections, utility coordination, final inspections and the handover record.
Planning in Troy
A ground-up number becomes more useful as the plans, site information, selections and allowances become more specific.
01
Once the scope and selections are agreed in writing, the agreed work is not repriced without a documented change. Owner-requested changes and concealed conditions are explained before changed work proceeds.
02
When a product includes a manufacturer warranty, keep its product information, registration details and terms. Manufacturer coverage belongs to the product; any workmanship responsibility should be stated separately in the project agreement.
03
We protect access areas, document changes and carry insurance for the work we perform. If property is damaged, the issue is documented and handled under the project agreement and applicable coverage.
04
At handover, keep the final scope, approved changes, inspection records, product information, care instructions and the right contact for any follow-up.
Planning ranges are starting points, not quotes. Final scope, selections, property conditions, approvals and written assumptions control the real project price.

How to read the range
A property review turns this range into a project-specific scope. The written scope, selections, allowances and exclusions are what make the final number comparable.
If an owner change or concealed condition affects cost or timing, it should be described in writing and approved before changed work proceeds.
The estimate explains what is included, what is excluded and which decisions need to be made before work starts. Agreed work is not repriced without a documented change.
When products include manufacturer warranties, product information and applicable terms stay with the project record. Workmanship responsibility belongs in the written agreement.
When a project needs drawings, permits or inspections, we identify the jurisdiction and likely sequence early so the schedule is built around real constraints.
Confirm parcel zoning, easements, site dimensions, access and utilities, then use Troy's current checklist to complete the submittal. A price should state which site assumptions remain unverified.
Yes. About 22% of Troy's 11,733 housing units, roughly 2,590 homes, were built in 2000 or later. That share of recent construction is the 4th highest of the 12 communities we serve. Identify whether the lot is infill or part of a planned subdivision, since the rules differ.
Troy's checklist calls for a scaled site plan with the project location and dimensions, plus information such as parking, utilities and easements. The required documents depend on the scope, so verify the current checklist before filing.
