Improvement 1031 Exchanges
How They Work for San Diego Multifamily Investors
Most investors are familiar with the traditional 1031 exchange: sell one property, reinvest the proceeds into another “like-kind” property, and defer capital gains taxes. It’s one of the most powerful wealth-building tools available to real estate investors.
In high-cost housing markets like San Diego, investors are constantly looking for ways to reposition older properties while preserving the tax advantages of an exchange. One strategy that occasionally emerges in these situations is the improvement 1031 exchange, sometimes referred to as a construction or build-to-suit exchange.
While not as widely used as standard exchanges, improvement exchanges can create unique opportunities for multifamily investors who plan to renovate, reposition, or add value to a property while still deferring capital gains taxes.
Below we’ll break down how improvement exchanges work, why investors use them, what the risks are, and how they differ from a traditional 1031 exchange.
What Is an Improvement 1031 Exchange?
An improvement 1031 exchange allows investors to use exchange funds to purchase and improve a replacement property before the exchange is completed.
In a traditional 1031 exchange, the investor must simply acquire property of equal or greater value within the exchange timeline. In an improvement exchange, however, the investor can allocate some of the exchange proceeds toward capital improvements made to the replacement property.
These improvements might include:
• Unit renovations
• Structural upgrades
• Adding additional units
• Reconfiguring layouts
• Major deferred maintenance repairs
The key difference is that the improvements must be completed and reflected in the property’s value before the 180-day exchange period expires. Investors considering any exchange strategy should also review the IRS Section 1031 guidelines to understand the legal framework behind like-kind exchanges.
Why Investors Use Improvement Exchanges
Improvement exchanges are most often used when an investor wants to acquire a property that has significant upside potential.
This strategy can be particularly relevant in San Diego’s multifamily market, where older apartment buildings often require upgrades but offer strong rental upside once improved.
Common motivations include:
Repositioning a Property
Investors may acquire a building that needs renovations and use exchange funds to modernize units, upgrade amenities, or improve operational efficiency.
Meeting Exchange Value Requirements
Sometimes the replacement property alone does not meet the required purchase price needed to fully defer taxes. Improvements can increase the total value of the replacement asset. Identifying the right replacement property is often the most important step, which is why many investors begin by reviewing a multifamily property valuation before entering an exchange.
Increasing Long-Term Cash Flow
Renovations can allow investors to reset rents to market levels and improve long-term property performance.
Unlocking Development Potential
In some cases, investors may use exchange funds to add accessory dwelling units (ADUs), expand the building footprint, or modernize older apartment buildings that require upgrades. Many San Diego multifamily owners are also addressing safety and compliance upgrades such as SB 721 balcony inspection requirements during renovation projects.
Why Investors Sometimes Avoid Improvement Exchanges
Despite their advantages, improvement exchanges are far less common than traditional 1031 exchanges. The primary reason is complexity.
Improvement exchanges require careful coordination between the investor, lender, contractor, and qualified intermediary.
Several factors can make them challenging:
Tight Timelines
Just like a traditional exchange, improvement exchanges must be completed within the 180-day exchange window.
However, the improvements must also be completed and reflected in the property value before that deadline.
Construction delays can therefore create serious risks.
Title Structure Requirements
Because exchange funds cannot be held directly by the investor, improvement exchanges require an Exchange Accommodation Titleholder (EAT) to temporarily hold title while improvements are completed.
This structure adds an additional layer of legal and transactional complexity.
Financing Coordination
If the replacement property requires financing, lenders must be comfortable with the improvement exchange structure, which may require additional documentation and approvals.
Selling the Relinquished Property in a 1031 Exchange
Every 1031 exchange begins with the successful sale of the relinquished property. Because investors must identify replacement properties within 45 days and complete the exchange within 180 days, timing and execution of the sale can significantly impact the success of the exchange strategy.
For multifamily owners in San Diego, preparing the property for sale and attracting qualified buyers quickly can be especially important. Generating strong investor interest early in the process can provide more flexibility when identifying replacement opportunities and coordinating exchange timelines.
For this reason, many investors evaluate how their property will be positioned in the market before initiating a 1031 exchange. Understanding the ACI Apartments marketing strategy can help owners see how targeted multifamily marketing campaigns are used to reach active investors and generate competitive offers when bringing apartment properties to market.
How Common Are Improvement 1031 Exchanges?
Improvement exchanges are much less common than traditional 1031 exchanges.
Most investors prefer the simplicity of a standard exchange because:
• The process is easier to execute
• Fewer parties are involved
• Financing is typically more straightforward
However, improvement exchanges are becoming more common in high-cost markets like San Diego where value-add opportunities can significantly increase property performance.
Experienced investors who regularly reposition properties sometimes use improvement exchanges as a way to combine tax deferral with strategic property upgrades.
What Lenders Require in an Improvement Exchange
Financing can be one of the more complicated aspects of an improvement exchange.
Because the replacement property may undergo construction or renovation before the exchange is completed, lenders typically require additional information before closing.
These requirements may include:
Construction Scope of Work
Lenders will usually want a detailed outline of planned improvements, including cost estimates and contractor information.
Budget and Timeline
The improvement plan must fit within the exchange timeline and demonstrate that the project can realistically be completed before the 180-day deadline.
Contractor Documentation
Licensed contractors and detailed project budgets may be required before loan approval.
Contingency Planning
Some lenders may require contingency reserves in case improvement costs exceed initial estimates.
Because financing requirements can vary depending on the structure of the exchange and the scope of renovations, investors should also understand common multifamily lending considerations before pursuing an improvement exchange.
Risks and Hurdles to Consider
Improvement exchanges offer flexibility, but they also introduce risks that investors should carefully evaluate.
Construction Delays
If renovations are not completed before the 180-day exchange deadline, the investor may lose the tax deferral benefit.
Budget Overruns
Unexpected construction costs can reduce the overall investment return.
Financing Complexity
Some lenders are less familiar with improvement exchange structures, which can slow the loan approval process.
Transaction Coordination
Improvement exchanges require coordination between multiple parties including the investor, intermediary, contractor, lender, and escrow teams.
Because of these moving parts, early planning is essential.
When an Improvement Exchange Makes Sense
Despite the complexity, improvement exchanges can be an effective strategy for investors pursuing long-term value creation.
Situations where they may make sense include:
• Acquiring a property with clear renovation upside
• Adding units or improving density potential
• Upgrading older apartment buildings in strong rental markets
• Increasing income potential through strategic improvements
In markets like San Diego, where multifamily housing demand remains strong, value-add improvements can significantly enhance long-term investment performance.

When executed correctly, they allow investors to reinvest into properties with strong upside potential while still preserving the tax advantages of a traditional exchange.
