Improvement Exchange Planning

An improvement exchange, sometimes called a construction or build-to-suit exchange, lets an investor apply exchange proceeds toward improvements on the replacement property in addition to its purchase price. This matters when a property's raw acquisition cost falls short of what is needed to fully absorb the relinquished gain, or when the desired replacement asset needs work before it functions as intended.

How the Exchange Accommodation Titleholder Structure Works

Because a taxpayer cannot hold title to replacement property while improvements are being made and still have those improvements count as part of the exchange, an exchange accommodation titleholder holds title during the construction period, with the investor directing and funding the work. The property is then transferred to the investor once improvements are substantially complete, all within the 180-day exchange period. This structure adds a layer of coordination but is often the only way to make a build-to-suit replacement work within federal exchange rules.

A Newport Center office suite acquired shell-condition and improved to a medical or specialty-office standard is a common example locally, since the raw purchase price alone may fall well short of the relinquished gain, while the finished, tenant-ready space absorbs the remaining exchange value. The accommodation titleholder's involvement should be scoped from the outset around exactly which improvements are intended, since scope changes mid-construction can complicate both the budget and the transfer timeline.

Why Coastal Zone Timing Makes This Structure Harder in Newport Beach

Any substantial construction or exterior improvement within the coastal zone, which covers much of Newport Beach including harbor-adjacent parcels and the Balboa Peninsula, generally requires a coastal development permit either from the city or, in some circumstances, directly from the California Coastal Commission. Permit review timelines in the coastal zone can run well beyond the 180-day exchange period, particularly for anything visible from public viewpoints or affecting public access to the waterfront.

An improvement exchange that depends on coastal permit approval needs a realistic assessment, done before the exchange accommodation titleholder takes title, of whether entitlements can actually clear in time. In many cases, only work that does not require new coastal review, interior tenant improvements rather than exterior or structural changes, is realistic within the exchange window.

Sequencing Work Within the 180-Day Window

Because the improvements have to be in place, or at least the exchange value has to be fully deployed, before the property transfers out of the accommodation titleholder's name and the exchange period ends, the construction schedule needs padding for permit delays, contractor availability in a high-demand coastal market, and inspection scheduling. A schedule built on an optimistic best case rather than a realistic one is the most common reason improvement exchanges run out of time.

Improvement Exchange Planning Checklist

Deciding Whether an Improvement Exchange Is the Right Tool

Not every replacement property that needs work justifies the added coordination of an improvement exchange structure. If the needed work is modest, interior, and permit-free, a standard forward exchange followed by post-closing renovation, funded outside the exchange, may be simpler and avoid the exposure of coastal permit timing colliding with a fixed federal deadline. Investors should review this tradeoff with their tax advisor before committing to the accommodation titleholder structure.

Where a candidate property sits within the coastal zone and the intended work includes anything visible from the street or the harbor, the planning stage should include an early conversation with city planning staff about which review track applies, rather than waiting for the permit application itself to surface the answer. A project that needs Coastal Commission-level review, rather than a locally issued coastal development permit, rarely fits inside the exchange window at all, and that possibility should be ruled out before an accommodation titleholder ever takes title.

Common 1031 Exchange Questions

What is an exchange accommodation titleholder?

It is a separate entity, arranged through the qualified intermediary, that holds title to replacement property during a construction or improvement period so the improvements can count toward the exchange before the property transfers to the investor. This structure has its own set of requirements that should be set up before construction begins.

Do all improvements in Newport Beach require a coastal permit?

Not all, but many exterior, structural, or waterfront-adjacent improvements within the coastal zone do require a coastal development permit from the city or the California Coastal Commission, and that review can take longer than the 180-day exchange period allows.

Can interior tenant improvements be done without triggering coastal review?

Interior work that does not affect the building's exterior, structure, or public coastal access often falls outside coastal permit requirements, but this should be confirmed with the local planning department for the specific property before relying on it in an exchange timeline.

What happens if construction is not finished by day 180?

Only the value of work actually completed and paid for by the time the property transfers out of the accommodation titleholder counts toward the exchange. Incomplete work at the deadline can leave less exchange value deployed than planned, potentially creating recognized gain.
