In Marana's New-Construction Sales Offices, the First Signature Is the One That Counts

You pull into the sales office at one of Marana's model home rows on a Saturday morning, maybe along West Tangerine Road where Mandarina and Monarch sit side by side, maybe further west where D.R. Horton is still moving product through Saguaro Bloom. A friendly on-site representative greets you at the door, offers water, and slides a clipboard across the counter. Name, phone number, email, and one line asking whether you're currently working with an agent. Nothing about it feels like a legal document. It reads like a guest list at a party.
It isn't. That signature, or the absence of one, is the moment that decides whether you have independent representation for the rest of that transaction, and most buyers walk out of the model home having never been told so.
Builders selling in Marana's active corridor, from KB Home and Meritage in Mandarina to Lennar and Richmond American in Monarch to D.R. Horton in Saguaro Bloom, operate under a practice known as procuring cause. In plain terms, whoever is credited with first bringing a buyer to a community typically has claim to any commission tied to that sale. If you walk in alone and register as an unrepresented visitor, the builder's own sales representative becomes the procuring party. Bring an agent with you on that same first visit, properly registered on the sign-in sheet, and the door to independent representation stays open for the life of that purchase.
The on-site rep is licensed, professional, and often genuinely helpful. They also work for the builder. Their job is to sell the builder's inventory at the builder's price, on the builder's timeline. That is not a criticism of the person behind the counter. It is simply who signs their paycheck.
Since August 17, 2024, a national rule change tied to the NAR settlement requires any MLS-participating agent to have a signed written buyer-broker agreement in place before showing a buyer a property, including a model home. That agreement has to spell out how the agent is paid, as a fixed amount or rate rather than a vague percentage, and it has to state plainly that commissions are negotiable rather than fixed by custom.
Layer that requirement on top of a builder's first-visit registration policy and the practical effect is this: the paperwork that protects your right to representation now has to exist before you ever walk through the model home door, not after you've fallen in love with a floor plan and started asking about upgrades. Waiting until after your first visit to think about an agent is no longer just inconvenient. It can close the door entirely.
The mechanics play out slightly differently depending on which Marana corridor you're touring.
In Mandarina, KB Home, Meritage Homes, and Lennar all hold active blocks along the same master plan, with Meritage marketing homes from the $330s and KB Home opening its Reserve and Horizon collections there at the end of October 2025. Three different builders on one master plan means three different sales offices, three different sign-in sheets, and three separate first-visit decisions if you're cross-shopping.
Monarch, the adjacent master plan, runs Lennar's collection spanning roughly $344,990 to $593,990 alongside Richmond American's newer Desert Bloom program, which opened earlier this year with homes in the upper $400s across roughly 2,070 to 3,030 square feet. Cross the street between the two and you've entered a second builder's registration process, whether or not you realize it.
Saguaro Bloom, tucked into the Tucson Mountain foothills west of Continental Ranch, is D.R. Horton's ground alone, which simplifies the registration question to a single sales office. It does not simplify the underlying rule.
And in Gladden Farms, where the master developer's raw land sold out in 2024, a handful of builder programs are still active, including Lennar's Springwood, KB Home's The Legends, and Meritage's Fieldstone. Buyers comparing these newer sections against the neighborhood's long-established resale inventory are often touring both in the same weekend, which means both a builder's first-visit rule and a resale showing agreement can be in play during the same afternoon of house hunting.
None of this is unique to Marana. It is standard practice across national production builders. What is useful to a Marana buyer specifically is knowing, before the weekend of touring begins, exactly which builders are active in which community and that each one runs its own version of the same first-visit rule.
The honest answer is typically no. Builders have historically budgeted for buyer-agent compensation as part of their marketing cost, on the logic that agents who bring qualified, motivated buyers are worth paying for. A builder that stopped compensating outside agents entirely would simply stop receiving those referrals. Post-settlement, that compensation is no longer automatic. It is negotiated and disclosed in writing between your agent and the builder, which is exactly why the written buyer-broker agreement matters. It puts the number in front of you before you tour, rather than leaving it as an assumption that only surfaces at closing.
If you have already visited a Marana model home and signed in on your own, the situation is not automatically unrecoverable, but it depends entirely on that specific builder's cooperating policy, which varies. Some builders will still allow you to add representation if no offer has been written yet. Others treat the first visit as final. The only way to know is to ask the builder directly, in writing, before you go any further, and to bring in an agent to have that conversation on your behalf rather than navigating it alone.
Does registering with an agent slow down my first visit to a model home? No. Registration is typically a short form, either completed online in advance or filled out at the counter alongside your agent. It adds a few minutes, not a delay to your tour.
Is this different if I'm buying a resale home in Marana instead of new construction? The underlying requirement for a signed buyer-broker agreement before touring applies to any MLS-participating agent showing you a property. Builder-specific first-visit registration policies are particular to new construction sales offices, since resale showings are already governed by the listing agreement between the seller and the listing agent.
What if I want to compare Mandarina, Monarch, and Saguaro Bloom in the same weekend? That is common, and reasonable. It simply means your agent needs to register you at each individual sales office before you tour, since each builder runs the practice independently even when the master plans sit a few miles apart.
Marana's builder corridor is genuinely worth the drive, whether that means Mandarina's mix of national builders, Monarch's wide price spread, or Saguaro Bloom's foothill setting. The mechanics of that first visit are not a reason to slow down. They are a reason to have your representation settled before you start.
