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. Build the schedule around complete documents, plan review, foundation, framing, rough systems and final approval. Each stage should name the party that releases the next one.
| Median year built | 1977 |
|---|---|
| Homes built before 1980 | 57% |
| Homes built in 2000 or later | 15% |
| Median home value | $287,200 |
| Owner-occupied homes | 67% |
About 15% of Centerville's 12,143 housing units, roughly 1,830 homes, were built in 2000 or later. That share of recent construction is the 4th lowest of the 12 communities we serve. New construction here is mostly infill or on remaining lots in established areas. The surrounding homes from the 1960s and 1970s set the street pattern, so the survey, setbacks, drainage and utility connections need to be verified for each lot before a plan is fitted to it.
Housing figures: U.S. Census Bureau, American Community Survey 2020-2024 5-year estimates, retrieved October 25, 2026. Statements about what homes of an age typically contain are general and must be confirmed on site.
For arithmetic only: applying the published building permit formula to a 2,400 square foot new home declared at $400,000 gives about $1,955 in building permit fees, before trade permits and the state surcharge. This shows how the schedule works and is not a price for the project.

Centerville's Building Inspection process covers residential and commercial construction and requires plans to be complete before approval can start.
A new home in Centerville needs the city's plan submission for building and trade systems, and the on-premises water and sewer connection falls under Public Health's separate permit.

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 Centerville
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.

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.

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.
Centerville's Building Inspection process covers residential and commercial construction and requires plans to be complete before approval can start. Review the lot, survey, grading, drainage, utilities, soil assumptions, plans, allowances and inspection stages before comparing a price. For new construction in Centerville, the scope should label site items that are confirmed, provisional or not yet priced.
Yes. About 15% of Centerville's 12,143 housing units, roughly 1,830 homes, were built in 2000 or later. That share of recent construction is the 4th lowest of the 12 communities we serve. Verify the survey, setbacks, drainage and utility connections for each lot.
Centerville's Building Inspection guidance says residential construction applications and plans should be submitted at least two weeks before the intended start, and commercial or multi-family work at least three weeks before. That is planning guidance, not a guaranteed review time.
