Sell a Duplex or Small Multifamily

Why a Duplex Doesn't Get the Standard Seller's Disclosure Notice

Tex. Prop. Code §5.008(a) requires a seller's disclosure notice from "a seller of residential real property comprising not more than one dwelling unit." A duplex is two dwelling units in one structure — it falls outside that definition, and no §5.008 notice is required on the sale. That's the opposite of every single-family page in this silo, where the notice (and the buyer's 7-day termination right if it's missing, under §5.008) is the seller's central disclosure obligation.

§5.008 not applying doesn't mean nothing applies. A seller still owes whatever the contract itself requires, the common-law duty in Texas not to conceal or misrepresent a known material defect, and exposure under the Texas Deceptive Trade Practices Act if a misrepresentation crosses into a false, misleading or deceptive act. Silence about a defect you don't know about isn't a violation of any of those; an affirmative lie about one you do know about can be, disclosure notice or not.

Practically: on a duplex, put what you know in writing anyway — most Texas contracts (including TREC's non-1-4-family commercial forms and negotiated addenda) let a seller attach a voluntary property condition statement, and it closes off the DTPA exposure that comes from staying silent about something a buyer later claims you knew and hid.

Two Units, Two Tenancies — What Chapter 92 Requires Per Unit

If either unit is occupied, each is its own tenancy under Texas Property Code Chapter 92, and the two don't merge just because they share a lot and a roof. Two leases, two deposits, two sets of obligations that transfer separately at closing.

Under §92.105, when the owner's interest in the property changes hands by sale, the new owner becomes liable for each tenant's security deposit from the date title transfers, and must deliver each tenant a signed statement acknowledging the acquisition and stating the exact deposit amount held. That's a §92.105 notice per unit, not one notice for the building — a two-unit duplex means two acknowledgment letters, two deposit figures, two dates the clock starts.

§92.201 requires a landlord to disclose the owner's or property manager's name and street address to each tenant. On a duplex with two separate leases, that disclosure runs to each tenant separately; it doesn't carry over automatically just because the same person owns both units.

None of this is a reason to delay selling — it's a reason to have both leases, both deposit ledgers and both tenant contacts assembled before you go to contract, so the transfer at closing is a handoff of paperwork the title company and the buyer can act on, not a scramble afterward. If you only have the one tenancy to move, the single-unit version of this same handoff is simpler still.

The Partial Homestead Exemption on an Owner-Occupied Duplex

An owner who lives in one unit of a duplex and rents the other doesn't lose the homestead exemption on the unit they occupy. Tex. Tax Code §11.13(k) states that a qualified residential structure "does not lose its character as a residence homestead if a portion of the structure is rented to another or is used primarily for other purposes that are incompatible with the owner's residential use of the structure" — but the exemption "does not apply to the value of that portion of the structure that is used primarily for purposes" incompatible with that residential use.

In plain terms: the homestead exemption follows the unit you actually live in, not the whole building. The Dallas Central Appraisal District applies §11.13(k)'s owner-occupied-portion standard when it values and exempts a duplex — an owner-occupied unit and a rented unit on the same parcel are not automatically taxed the same way, and a buyer or seller should confirm the parcel's current exemption split with DCAD rather than assume the whole property carries one homestead exemption or none at all.

Unpermitted Units, Zoning and the Building-Permit History

The City of Dallas's own certificate-of-occupancy rule carves duplexes out of the requirement. The Building Inspection page states it plainly: "Except for single family and duplex uses, a person shall not use or change the use of a building, a portion of a building, or land without obtaining a Certificate of Occupancy (CO) from the building official." A properly permitted, genuinely two-unit duplex doesn't need its own CO to be occupied as a duplex.

The exposure isn't the CO — it's what got the building to two units in the first place. A single-family house converted into a duplex, or a duplex converted into a triplex or fourplex, without the permits and zoning approval that conversion required, is an unpermitted-use problem: a use the zoning doesn't authorize and a floor plan the city's permit file doesn't match. That's the version of this issue that surfaces at resale, because Dallas's permit and inspection history is a public record — a converted garage apartment, an added kitchen, or a third meter with no matching permit is discoverable by anyone who pulls the file, buyer's inspector included.

We don't require you to resolve permit history before selling. We buy houses with an unclear or incomplete permit trail as-is, and price the uncertainty into the offer rather than asking you to bring the building up to code first.

Can a Duplex Still Get Financed Like a House?

Yes. Fannie Mae's Selling Guide, B2-3-01 General Property Eligibility (effective 09/03/2025), states that "Fannie Mae purchases or securitizes first-lien mortgages that are secured by residential properties when the dwelling consists of one to four units" — a duplex, triplex or fourplex is inside that definition, not outside it. That keeps a 2-4 unit building inside the same conventional, agency-backed financing pool as a single-family house, with a materially larger pool of eligible buyers than a 5+ unit building, which falls out of residential financing entirely and into commercial multifamily underwriting — different lenders, different terms, a smaller buyer pool.

That's part of why a duplex is a workable retail listing for the right buyer (often an owner-occupant who wants to live in one unit and rent the other) and also why it's a workable cash sale for a seller who doesn't want to carry it through that process. When that is the choice, we buy 2-4 unit buildings in Dallas for cash, without waiting on a residential-financing buyer to qualify.

What Closing Looks Like on a Duplex Sale

An occupied duplex sale carries a short list of building-specific items a single-family closing doesn't: a current rent roll for both units, estoppel certificates from each tenant confirming their lease terms and deposit amount independently of what the seller reports, and an assignment of both leases to the buyer at closing. The §92.105 deposit-transfer acknowledgment (above) gets delivered to each tenant around the same time.

If a unit is vacant, that shortens the list — no lease to assign, no estoppel to collect — but the rent roll and any recent lease history still matter to what the building is worth occupied versus vacant. If the property in question isn't a duplex at all, the same closing mechanics apply to a single-family house in the same county, and we buy those in whatever shape they're in — permits, deferred repairs and all — closing in as little as 7 days.
