What Documents Should You Give a Real Estate Appraiser? A Niagara Homeowner Checklist

If you have booked a residential appraisal, one of the easiest ways to help the process go smoothly is to gather the documents that explain the property. The appraiser still completes an independent inspection, market analysis and verification process, but clear records can reduce uncertainty and help ensure important features are not overlooked.

For homeowners in Niagara Falls, St. Catharines, Thorold, Welland, Fort Erie, Port Colborne and the surrounding Niagara Region, the most useful records usually relate to the site, building size, renovations, permits, income-producing areas and the effective date of the assignment.

Quick answer: what should you have ready?

If available, prepare a recent survey or site plan, property tax bill, floor plans, a list of renovations with approximate dates, building permits, invoices for major improvements, and any documents relating to a secondary suite, tenancy or special property feature. You do not need every item on this list, and an appraisal can often proceed without them.

1. Survey, site plan or property sketch

A survey or site plan can help confirm lot dimensions, the placement of improvements, rights-of-way, easements and structures such as detached garages, sheds or additions. This can be especially helpful for irregular lots, waterfront properties, rural properties and sites where boundaries are not obvious during the inspection.

If you do not have a survey, do not delay booking the appraisal. The appraiser may be able to rely on other available sources, subject to the scope of the assignment and the reliability of the information.

2. Property tax bill and municipal information

A current property tax bill can help confirm the municipal roll number, legal description and assessment information. Municipal records may also assist with zoning, permits and property classification.

Assessment value is not the same as current market value. In Ontario, an appraisal considers the relevant market evidence as of the effective date rather than simply adopting the assessed value shown on the tax record.

3. Floor plans and measurements

Architectural plans, builder plans or previous measurement sketches can be useful when the home has an unusual layout, additions, finished areas with limited access or multiple living units. The appraiser may still measure the dwelling independently or reconcile the plans with observations made during the inspection.

Gross living area is an important comparison factor, so it is helpful to identify whether a stated area includes only above-grade finished space or also includes a basement, garage, enclosed porch or other area that may be treated separately.

4. A renovation and improvement list

Prepare a simple list of major improvements and the approximate year each was completed. Useful examples include the roof, windows, furnace, air conditioning, electrical service, plumbing, kitchen, bathrooms, flooring, basement finishing, additions, decks, garages and major exterior work.

Receipts are helpful, but renovation cost does not automatically equal an identical increase in market value. The appraiser considers how buyers in the local market react to the improvement, its quality, condition, utility and remaining economic life.

5. Permits and final inspection records

Permits can be particularly important for additions, structural changes, finished basements, accessory apartments, converted garages and major electrical or plumbing work. If the municipality issued a final inspection or occupancy document, include that as well.

An appraiser does not provide a legal opinion about zoning or building-code compliance. When legality or permitted use matters to the assignment, reliable municipal documentation can help support the analysis and identify any assumptions or limiting conditions that may be required.

6. Secondary suite or rental documents

If the property includes a basement apartment, in-law suite, duplex configuration or other income-producing area, provide any available lease, rent schedule, utility arrangement, permit information and documentation of the unit's layout. Clearly identify which rooms and entrances belong to each area.

A property's physical use and its legally permitted use are not always the same. The appraiser may need to distinguish between a legal second unit, a non-conforming use and a single-family dwelling with an in-law arrangement, depending on the available evidence.

7. Documents tied to the purpose of the appraisal

The right documents also depend on why the appraisal is being completed.

• Estate or probate: provide the required valuation date, often the date of death, along with any property information that describes its condition on that date.

• Matrimonial or separation matters: confirm the effective date requested by the lawyer or parties and disclose any relevant changes made after that date.

• Capital gains or tax planning: provide the applicable historical date, acquisition information and records of significant capital improvements.

• Financing or refinancing: provide the lender or mortgage broker instructions if they were not sent directly to the appraiser.

• Pre-listing or private sale: provide any current listing, accepted offer or known terms that may be relevant to the assignment.

• Construction or renovation: provide plans, specifications, budgets, contracts and a clear description of the proposed completed condition.

8. Previous listings, offers or appraisals

Tell the appraiser if the property is currently listed, recently sold, subject to an agreement of purchase and sale or was appraised previously. A prior appraisal does not determine the new result, but it may contain factual information worth verifying. The current appraiser must still form an independent opinion based on the assignment's effective date, intended use and available evidence.

What you do not need to do before the inspection

You do not need to stage the home as if professional listing photos are being taken. Reasonable access and visibility matter more than perfect presentation. The appraiser needs to view the interior, exterior, mechanical systems and relevant site improvements.

Try to provide safe access to every room, the basement, garage and utility areas. If an area cannot be inspected, tell the appraiser in advance so the limitation can be addressed appropriately.

A simple day-of-inspection checklist

• Make sure all rooms and levels are accessible.

• Secure pets and advise the appraiser of any safety concerns.

• Provide the renovation list and documents in one folder or email.

• Point out features that may not be obvious, such as upgraded insulation, buried services, owned solar equipment or a separate utility meter.

• Answer factual questions, but do not worry about trying to sell the property to the appraiser.

Frequently asked questions

Do I need every document before booking an appraisal?

No. Book the appraisal when you need it and provide the records you have. The appraiser can tell you if a particular missing document is important to the assignment.

Will receipts make my appraised value higher?

Not automatically. Receipts can establish what was completed and when, but market value is based on how the market recognizes the improvement, not simply its cost.

Should I provide a previous appraisal?

Yes, if it contains relevant property facts or relates to a historical condition, but the new appraiser must complete an independent analysis and may reach a different conclusion.

What if the property has an unverified apartment?

Disclose it and provide any available municipal records. The appraiser can describe the observed configuration while carefully addressing whether its legal status has been confirmed.

The bottom line

Good documentation helps the appraiser understand the property, verify important facts and explain the analysis clearly. It does not replace the inspection or guarantee a particular value, but it can make the assignment more efficient and reduce avoidable uncertainty.
