Fact-Checking Policy

Last Updated: October 9, 2026

Welcome to ShedCost.us. Our Fact-Checking Policy explains the standards we use to evaluate information, verify calculations, assess sources, and address factual inaccuracies in our website content.

ShedCost.us provides shed cost calculators, material estimation tools, construction planning information, and educational resources. We recognize that visitors may use this information to make important budgeting and project planning decisions.

Our goal is to provide information that is clear, accurate, useful, and transparent about its limitations. This policy describes seven essential fact-checking standards that guide our content review and quality expectations.

1. Our Commitment to Accurate Information

The primary purpose of our Fact-Checking Policy is to establish a consistent approach to evaluating factual claims and numerical information presented on ShedCost.us.

We aim to distinguish verifiable facts from assumptions, estimates, general recommendations, and information that may change depending on location or market conditions.

Our fact-checking standards emphasize:

Using credible and relevant information sources.
Checking mathematical formulas and calculation logic.
Identifying assumptions that influence estimates.
Avoiding misleading or unsupported claims.
Distinguishing estimated costs from confirmed prices.
Reviewing information when errors or significant changes are identified.
Providing a way for readers to report possible inaccuracies.

Although we aim for accuracy, no online resource can guarantee that every piece of information will remain complete, current, or applicable to every individual situation.

2. Source Verification and Research Standards

Reliable information begins with evaluating the quality and relevance of its sources. Our Fact-Checking Policy prioritizes sources that provide identifiable evidence, clear methodologies, and information appropriate to the subject being discussed.

Primary and Authoritative Sources

Depending on the topic, relevant reference materials may include:

Official government publications and regulatory guidance.
Building department requirements and publicly available construction regulations.
Manufacturer product specifications and installation documentation.
Recognized construction industry organizations.
Educational institutions and technical research publications.
Published material pricing information and documented contractor quotations.

For example, the U.S. Department of Energy's Energy Saver resources provide useful technical information about insulation and energy efficiency.

Similarly, the National Institute of Standards and Technology provides authoritative resources related to measurement and technical standards.

Evaluating Source Reliability

When evaluating information, relevant considerations include the source's expertise, publication date, supporting evidence, methodology, and potential commercial interests.

A source may be useful for one purpose but unsuitable for another. For example, a manufacturer's product specification may support material dimensions, while local supplier quotations may be more appropriate for estimating current prices.

When information cannot be verified with reasonable confidence, it should not be presented as an established fact.

3. Calculator Formula and Mathematical Verification

ShedCost.us provides calculators that help visitors estimate project costs, quantities, dimensions, and other construction-related values.

Mathematical accuracy is an important part of our Fact-Checking Policy because incorrect formulas or assumptions can produce misleading estimates even when the input values are valid.

Reviewing Calculation Logic

Calculator formulas should be based on appropriate mathematical relationships, clearly defined input values, and consistent measurement units.

Relevant checks include:

Confirming that formulas match their intended calculation purpose.
Checking conversions between measurement units.
Testing representative numerical examples.
Considering zero values, missing inputs, and unrealistic entries.
Checking rounding and displayed results.
Distinguishing mathematical outputs from assumptions used in cost estimates.

Example of a Formula Check

A rectangular shed measuring 10 feet long and 12 feet wide has a floor area calculated as follows:

Floor Area = Length × Width

10 × 12 = 120 square feet

This relationship can be checked independently using basic geometry. Visitors can also explore the Shed Square Footage Calculator for related area calculations.

More complex calculators may depend on material quantities, waste allowances, labor rates, and other assumptions. Those assumptions must be considered separately from the mathematical formula.

Additional information about estimation principles is available in our Calculator Methodology and Assumptions page.

4. Cost Estimates, Pricing Data, and Assumptions

Construction costs can vary substantially depending on geographic location, material availability, project specifications, contractor pricing, and market conditions.

Our Fact-Checking Policy requires a clear distinction between estimated costs and actual prices supplied by vendors or contractors.

Understanding Estimated Prices

A calculator may generate an estimated project cost using user-provided values, predefined assumptions, or a combination of both.

Such results should be understood as planning estimates rather than guaranteed purchase prices or binding quotations.

Factors that may affect actual costs include:

Regional lumber and building material prices.
Local contractor labor rates.
Foundation and site preparation requirements.
Roofing and siding material selections.
Delivery and installation expenses.
Permit fees and local building requirements.
Material waste, taxes, and unexpected expenses.

Example of an Estimated Shed Cost

Consider a hypothetical 120-square-foot shed project with an assumed construction cost of $45 per square foot.

Estimated Cost = Floor Area × Assumed Cost Per Square Foot

120 × $45 = $5,400

The arithmetic produces an estimated cost of $5,400. However, the $45 rate is an illustrative assumption, not a verified current market price.

The final project price could differ because of material choices, local labor, site conditions, and expenses excluded from the example.

Our Shed Cost Per Square Foot Calculator can help visitors explore this type of calculation using their own inputs.

5. Editorial Review and Content Updates

Factual reliability requires more than checking information at the time of initial publication.

Our Fact-Checking Policy also addresses the need to reconsider information when new evidence, updated regulations, or significant market changes become relevant.

Content Review Considerations

When content is created or reviewed, the following questions help guide quality evaluation:

Are factual claims supported by credible information?
Are numerical examples mathematically correct?
Are important assumptions explained?
Is the information presented in appropriate context?
Are technical terms and measurement units used consistently?
Could outdated information create a misleading impression?
Are limitations communicated clearly?

When Information May Be Updated

Content may require revision when an error is discovered, a calculation needs correction, a referenced source changes, or new information materially affects the usefulness of the page.

Some information, such as basic geometric formulas, remains relatively stable. Other information, including building material prices and permit requirements, may change more frequently.

Review needs therefore depend on the nature of the content rather than a single universal update schedule.

Our broader standards for content preparation are described in the Editorial Policy .

6. Corrections and Error Reporting

Despite reasonable efforts to provide accurate information, factual, technical, or editorial mistakes may occasionally occur.

Our Fact-Checking Policy supports reviewing reported inaccuracies and making appropriate corrections when an error is confirmed.

Types of Errors That May Require Correction

Examples include:

Incorrect mathematical formulas.
Calculation results that do not match inputs.
Incorrect unit conversions.
Misstated construction terminology.
Outdated or misleading factual statements.
Incorrect references or broken source links.
Ambiguous assumptions that materially affect estimates.

How Corrections Are Evaluated

When a possible error is brought to our attention, the appropriate response depends on the nature and significance of the issue.

A correction review may involve:

Identifying the specific statement, formula, or result being questioned.
Comparing the information with reliable references or independent mathematical calculations.
Determining whether the issue is a factual error, an outdated assumption, or a difference in interpretation.
Updating or clarifying the affected content when appropriate.
Rechecking related information if the correction affects other calculations or explanations.

Minor typographical corrections may not require a separate public notice. Significant changes may be identified through updated content or revision information when appropriate.

Reporting a Possible Error

Visitors who identify a possible inaccuracy are encouraged to contact ShedCost.us through our Contact Us page.

To help us understand the issue, please include the page title or URL, the information being questioned, and a brief explanation of the suspected error.

Supporting references or a reproducible calculation example may also be helpful. Submitting a report does not guarantee that a requested change will be made.

7. Transparency, Independence, and Limitations

Transparency is an essential part of responsible fact-checking. Readers should be able to understand what information represents, how an estimate is produced, and where uncertainty exists.

Facts Versus Estimates

A mathematical relationship can be objectively verified, while an estimated construction price depends on assumptions and variable real-world conditions.

For example, calculating the area of a rectangular floor is different from estimating the labor cost of constructing that floor.

Both calculations may be useful, but their levels of certainty are not necessarily the same.

Commercial Independence

Advertising, affiliate relationships, or other commercial considerations should not determine whether a factual claim is considered accurate.

Product claims and pricing information should be assessed according to relevant evidence rather than promotional language alone.

Limitations of Website Information

ShedCost.us provides general informational and educational resources. Our calculators and articles are not substitutes for professional engineering, architectural, legal, or construction advice.

Local building requirements can vary significantly. Visitors should confirm applicable codes, permit rules, zoning restrictions, and construction requirements with the appropriate local authorities.

The International Code Council provides resources concerning model building codes and standards. Local adoption and amendments should always be verified separately.
