An improvement exchange, sometimes called a build-to-suit exchange, lets an investor put exchange funds toward construction or renovation on the replacement property rather than just its purchase price. It solves a problem a standard exchange cannot: what happens when the best replacement candidate is a raw parcel or a building that needs substantial work before it is worth what the relinquished property sold for.
Why Improvements Need Their Own Structure
Exchange funds can only be applied to real property the investor already owns as of the improvement, and construction performed on a property the investor already holds does not count as an exchange, it is simply a renovation paid for with the investor's own after-tax money. To use exchange funds for construction, the improvements have to happen while the property is titled to an exchange accommodation titleholder, the same parking entity used in a reverse exchange, not the investor directly.
How the EAT Holds Title During Construction
The exchange accommodation titleholder takes title to the replacement property and directs construction, using exchange funds released by the qualified intermediary to pay contractors as the work proceeds. Because the EAT, not the investor, owns the property during this phase, every improvement dollar spent before title transfers to the investor counts toward the exchange. Once construction is far enough along, or the 180-day deadline is approaching, title transfers from the EAT to the investor, and improvement value credited at that point locks in.
The 180-Day Ceiling on Construction Value
This is where an improvement exchange gets unforgiving: all construction that counts toward the exchange has to be complete, or at minimum paid for and incorporated into the property, before day 180. A New Orleans investor planning a ground-up build-to-suit on a river corridor industrial parcel needs a contractor and permitting timeline that realistically fits inside 135 remaining days after the 45-day identification period, since any work completed after title transfers to the investor no longer counts as exchange-funded improvement, it becomes an ordinary post-closing renovation.
Permitting Realities in Orleans and Jefferson Parish
Historic district design review, floodplain permitting, and standard commercial building permits in Orleans and Jefferson Parish can each add weeks an improvement exchange's calendar does not have room for. Investors considering a build-to-suit exchange on a Central Business District or historic-adjacent parcel should get a realistic permitting timeline from the parish or the Historic District Landmarks Commission before committing to the strategy, since a permitting delay does not pause the 180-day deadline the way it might pause an ordinary construction project.
Valuing Improvements Correctly at Transfer
The value credited toward the exchange is the value of the improvements actually incorporated into the real property by the time title transfers from the EAT to the investor, not the value of a signed construction contract or materials sitting on site. Prepaid deposits to a contractor, or building materials purchased but not yet installed, generally do not count toward the exchange value at the transfer date, which is why tracking substantial completion against the calendar, not just spending against the budget, is what actually protects the exchange.
A realistic contingency buffer, built into the construction schedule from the start rather than added after a delay appears, is what separates an improvement exchange that closes cleanly from one that scrambles to transfer title on day 179 with unfinished work still on site.
Common 1031 Exchange Questions
What problem does an improvement exchange solve?
It allows exchange funds to pay for construction or renovation on the replacement property, which is useful when the best available replacement is raw land or a building that needs work before it matches the value of the property sold.
Why can't an investor just buy a property and renovate it with exchange funds afterward?
Exchange funds can only be applied to property not yet owned by the investor. Once the investor holds title, further construction is a personal renovation, not part of the exchange, so the property must be parked with an EAT during the improvement phase.
What is the deadline for completing improvements in this type of exchange?
All construction that counts toward the exchange must be complete, or paid for and incorporated into the property, before day 180. Work completed after title transfers to the investor no longer qualifies.
Who holds title to the property while construction is happening?
An exchange accommodation titleholder, the same type of entity used in a reverse exchange, holds title and directs the improvements using released exchange funds until the work is far enough along to transfer title to the investor.
Are permitting delays a bigger risk here than in a standard exchange?
Yes. Historic district review, floodplain permitting, and standard commercial permitting in Orleans and Jefferson Parish can consume weeks, and the 180-day deadline does not pause for permitting delays.
Is an improvement exchange more complex than a standard forward exchange?
Generally yes, since it combines the parking structure used in reverse exchanges with a construction budget and contractor timeline that both need to fit inside the same 180-day window.
