Quick Answer: If a Massachusetts home has extra living space, a separate entrance or a second kitchen, explain the actual layout and use before ordering an appraisal. Gather available plans and approval records. Do not assume that physical features establish a legal additional dwelling, that all area is measured alike, or that projected rent will be included.

Homeowners use terms such as in-law space, accessory apartment and finished lower level in different ways. A label in a listing may leave important questions unanswered about the property being appraised.
A useful starting point is a factual description. Describe what exists, how it is used and which records support the description. Obtain current municipal or professional guidance on legal status rather than expecting the appraisal request to resolve it.
What should your initial description include?
Explain where the space is, how it connects to the main home and which facilities it contains. Identify whether it is occupied and by whom in general terms, without supplying unnecessary personal information. Include any access limitation.
Use plain wording when status is uncertain: 'finished space with a kitchen and separate entrance; approval records not yet confirmed.' That is more useful than selecting a legal category without evidence.
Which plans and approval records should you collect?
Gather the records already available, including dated plans, permits and completion-related documents. Identify the issuing source and whether each document represents a proposal, approval or completed work. Ask the relevant authority about missing or unclear records.
If the current layout differs from a plan, explain the difference. Do not edit a plan to make it appear official or current. The appraiser can then discuss what further information the assignment needs.
How should you handle square footage?
Provide prior measurement records with their dates and purpose. Explain which areas the numbers include. Ask how the requested service will describe the spaces and what deliverable you will receive.
A total taken from a marketing plan should not automatically replace the area used in an appraisal. Avoid adding separate figures together without understanding their definitions. A measurement service also should not be presented as a zoning or occupancy approval.
What if you plan to rent the space?
Distinguish current use, documented arrangements and future plans. Ask the appropriate professional about permitted use and the obligations involved. A projected rent from an online listing is not the same as an existing agreement or verified income.
Tell the appraiser why the space matters to your decision and who will rely on the report. The proposed assignment can then address the property as supported by the available evidence, rather than an assumed future condition.
Frequently Asked Questions
Does a second kitchen prove a second legal unit?
No. Seek confirmation of the relevant legal status from the appropriate authority or adviser.
Will all finished space count in one area total?
Ask which definitions and reporting requirements apply. Physical finish alone does not answer the question.
Can I use a measurement report as an occupancy approval?
Do not assume so. Confirm approvals separately with the responsible authority.
