How Builder Consent for an Assignment Sale Actually Works

Every assignment sale we work on has one non-negotiable first step: builder consent. It's also the step most first-time assignors and assignees underestimate. Here's how it actually works.

Why Builder Consent Exists

Nearly every pre-construction purchase agreement includes a clause requiring developer approval before the original buyer can assign their contract to someone else. Builders include this for a straightforward reason: they want visibility into and control over who ends up owning units in their building, and they typically want to protect their own remaining sales program from being undercut by assignors listing below current builder pricing.

What the Consent Process Actually Involves

1. Formal request submission. The assignor typically submits a formal request to the builder, often through their lawyer, once they have an assignee lined up or are preparing to market the unit (depending on the builder's specific marketing restrictions).

2. Builder review. The developer's legal or sales team reviews the request — this can include confirming the original purchase agreement is in good standing, that all deposits are current, and sometimes reviewing the proposed assignee's basic qualifications.

3. Assignment fee payment. Most builders charge a fee for processing an assignment consent, which varies significantly from one developer to another — confirm the current fee directly rather than assuming a number from an older purchase agreement or a friend's experience with a different building.

4. Formal written consent. Once approved, the builder issues written consent, which is what actually allows the Assignment Agreement of Purchase and Sale between assignor and assignee to proceed to closing.

Realistic Timelines

Builder consent timelines vary enormously — some developers process requests within a couple of weeks, while others take considerably longer, particularly if the building is actively managing a high volume of assignment requests near completion. Never assume a specific timeline without confirming directly with the builder or their legal representative, and build buffer time into any closing date you're negotiating.

What Can Go Wrong

The builder simply says no. Consent isn't automatic — a developer can decline a specific assignment request, particularly if the original buyer isn't in good standing on their payment schedule.

Timelines run longer than expected. If you've built a tight closing timeline around an assumed consent date and the builder takes longer, you can end up in a difficult position with the other party to the assignment.

Fees are higher than anticipated. Assignment fees aren't standardized across builders — confirm the actual number before you finalize pricing on either side of the transaction.

The assignee doesn't meet the builder's basic requirements. Some developers apply their own qualification criteria to assignees, separate from what the assignor and assignee have agreed to between themselves.

What This Means If You're Selling an Assignment

Start the builder consent process as early as realistically possible — don't wait until you have a signed assignee agreement to find out the builder's specific process and timeline. Confirm your original agreement is in good standing before you even begin marketing.

What This Means If You're Buying an Assignment

Don't treat builder consent as a formality — confirm with your lawyer that it's been properly obtained and documented before you finalize your side of the transaction. An assignment that proceeds without proper builder consent can create serious complications at final closing.

The Bottom Line

Builder consent is the step that determines whether an assignment sale can happen at all, and it's exactly the part of the process most likely to introduce delays or complications if it isn't handled early and correctly. Treat it as the first priority in any assignment transaction, not a formality to sort out later.
