A basement apartment with its own entrance. A converted garage with a kitchenette. A cottage behind the main house. Accessory dwelling units solve real problems for families housing a parent or offsetting a mortgage, and they sit at the intersection of three sets of rules that do not talk to each other. Here is what a buyer or seller should confirm.
Three questions, not one
Is the unit permitted, meaning the construction itself was inspected and approved. Is the use allowed, meaning zoning permits a second dwelling on the lot. And do private restrictions permit it, meaning the recorded covenants and any association rules do not prohibit it.
Those are three separate approvals from three separate sources, and a property can satisfy one or two while failing the third. A basement apartment can be beautifully built and fully permitted as living space while zoning still prohibits its use as a separate dwelling.
Permitted construction is not permitted use
This is where most confusion lives. A permit confirms the work met code. It does not confirm the locality allows a second household on that lot. Ask about both, because the answers come from different parts of the same office.
What the title record shows and does not
Recorded covenants restricting the property to single family use, or prohibiting rental of any portion, appear in the search and become exceptions on your policy. Those are real and they bind you. The associated discussion is in restrictive covenants.
Zoning does not appear in the land records, and neither does the permit history. So a clean title search tells you nothing about whether the unit is lawful. We can tell you what a prior owner recorded against the property. We cannot tell you what the county will permit, and we will not pretend the search covers it.
Where it bites
At appraisal, because an appraiser deciding whether to value the unit as income or as unfinished square footage will look at whether it is legal. At the lender, because loan programs treat a two unit property differently from a single family home with a bonus room. At the insurer, because a tenant in an unpermitted unit raises coverage questions.
And at resale, because you will be asked the same questions you should have asked, and by then the answer is yours to give. Unpermitted work generally is covered in selling a home with unpermitted work.
A tenant in an unlawful unit is a complication, not just a risk
If the unit turns out to be prohibited, you may have someone living there who has rights under a lease and a locality telling you the use must stop. Those two facts do not resolve each other quickly, which is why the question belongs before purchase rather than after the first tenant.
What to ask before you buy
Pull the permit history from the locality and see whether the unit appears. Ask zoning directly whether a second dwelling is allowed on that lot, in that district, at that size. Read the recorded declaration for single family or rental restrictions. And if the seller has been renting it, ask how long, to whom, and whether anyone has ever asked a question about it.
Where the property is in an association, the disclosure package should reveal any rental or occupancy restriction, which is worth reading for that specifically, as noted in buying a condo or home in an association.
If you are building one
The order matters. Confirm zoning permits the use, confirm the covenants do not prohibit it, then pull the permit and build. Doing it in the reverse order, which is common, produces a finished unit that cannot lawfully be occupied and a homeowner who has spent the money already.

Common questions
Is a permitted basement apartment automatically legal to rent?
No. A permit confirms the construction met code. Whether zoning allows a second dwelling on the lot is a separate question from a different part of the same office, and covenants are a third.
Will the title search tell me if the unit is legal?
No. A search shows recorded covenants and restrictions. Zoning and permit history are not in the land records, so a clean search says nothing about whether the use is lawful.
Can covenants prohibit a second unit?
Yes. A recorded declaration limiting the property to single family use, or prohibiting rental of any portion, binds you and appears as an exception on your title policy.
Why does the lender care?
Loan programs treat a property with two dwelling units differently from a single family home, and an appraiser deciding whether to credit the unit as income will consider whether it is lawful.
What if the seller has been renting it for years?
That is evidence it has been possible, not that it is permitted. Unlawful units operate for years until someone complains, and the complaint arrives after you own it.
What order should I do things in if I am building one?
Confirm zoning allows the use, confirm the covenants do not prohibit it, then permit and build. Building first and asking afterward produces a finished unit nobody may lawfully occupy.
