To convert apartments to condos, you take a single rental building owned by one entity and legally divide it into individually owned units by recording a condominium declaration in the county land records, after satisfying your state’s tenant-protection rules, local zoning and permit requirements, lender-eligibility thresholds, and insurance and tax planning. Each of those pieces can stop the project on its own, so the order in which you approach them matters as much as the work itself.
Test Feasibility Before You Spend
The first question is whether buyers in your submarket want condos at prices that justify the conversion costs. Study comparable condo sales, vacancy rates, and absorption timelines. A building surrounded by rental inventory with weak buyer demand is a poor candidate no matter how attractive the per-unit math looks. A well-located property in a supply-constrained ownership market can produce significantly higher total proceeds than a bulk sale as a rental.
On the cost side, budget for legal and professional fees, renovation and code-compliance work, holding costs during the conversion period, and marketing. You will need a real estate attorney, a surveyor or engineer, an accountant, and eventually a sales team. Legal fees for drafting the declaration, bylaws, and disclosure documents can run well into five figures on a larger project. Recording fees, permit application fees, and inspection costs vary by jurisdiction and add up quickly, especially when the local building department charges per unit.
Get a physical assessment early. A licensed engineer should evaluate the roof, structural elements, mechanical systems, plumbing, electrical, and common-area finishes. Even where full code modernization isn’t required, health and safety hazards must be corrected, and buyers will expect a certain standard. This assessment also feeds directly into the reserve study and HOA budget.
Work Within Your State’s Condominium Act
Every state has a condominium enabling statute that governs how condominiums are created, operated, and terminated. Many are modeled on the Uniform Condominium Act, but each version has its own quirks. The universal rule is that a condominium comes into existence only when a declaration is recorded in the land records of the county where the property sits. Until then, there are no individual units to sell.
The declaration is the foundational legal document. It submits the property to condominium ownership and must include a legal description of the land, identification of each unit by number or letter, a survey and graphic description of the improvements, each unit’s percentage interest in the common elements, and allocation of responsibility for common expenses. Every person with a recorded interest in the property, including mortgage holders, must either join in executing the declaration or consent in writing.
Alongside it, you draft bylaws and rules. The bylaws establish how the association operates: board elections, meeting procedures, voting rights, and assessment collection. The rules cover day-to-day matters like noise, pets, parking, and use of shared spaces. Together they form the governing framework buyers receive before purchase.
The Public Offering Statement
Most states require the developer to deliver a public offering statement to every prospective buyer before or when the purchase contract is signed. It must fully and accurately describe the development, including the financial condition of the association, the budget, any pending litigation, and the physical condition of the building. For a conversion specifically, the statement typically must include an engineering report on the building’s major systems and their estimated remaining useful life.
This is not a formality. If the statement is missing required content or delivered late, most states give the buyer a right to rescind. Current financial projections and honest condition assessments matter here more than anywhere else in the transaction.
Handle Tenant Rights Before Anything Else
Existing tenants are the stakeholders most directly affected, and the law in most jurisdictions gives them substantial protections. The specifics vary, but three categories appear almost everywhere conversions are regulated.

Ignoring these rules can derail the project. Some cities have imposed outright moratoriums on conversions or require a minimum percentage of units to remain affordable. A handful of major cities layer enough restrictions that the economics no longer work. Research local conversion ordinances before committing capital.
Clear Local Zoning, Permits, and Inspections
Local zoning ordinances dictate whether a conversion is allowed on your parcel. Some areas zone exclusively for rental housing, and converting requires a variance or special-use permit. Others allow conversions by right but impose conditions like minimum unit counts or parking ratios. Check with the local planning or zoning department before drafting legal documents.
Most jurisdictions also require a conversion permit before you can offer units for sale. The application typically includes the proposed declaration, engineering reports, floor plans, and proof that tenant notice requirements have been met. In some cities you need both a preliminary approval from a housing agency and a final conversion permit from the building department.
Building inspections are separate. The building department will inspect for code compliance, focusing on fire safety, structural integrity, egress, and habitability. Deficiencies must be corrected before final permits issue and new owners can occupy.
Confirm You’re Exempt From Federal Registration
The Interstate Land Sales Full Disclosure Act is a federal law that can catch converters off guard. Its registration and disclosure requirements technically apply to any sale of 100 or more lots or units using interstate commerce. Filing a registration statement with the Consumer Financial Protection Bureau and preparing a detailed property report is expensive and time-consuming.
Most conversions qualify for one of two exemptions. The first covers any sale of improved land with a residential or condominium building already on it, or where the seller is obligated to complete the building within two years of the sale contract. The second, broadened in 2014, covers the sale of any condominium unit regardless of project size, as long as the unit is designated for separate ownership under a condominium declaration, the buyer will receive sole ownership plus an undivided interest in common elements, and the unit is improved at the time of conveyance.1Office of the Law Revision Counsel. 15 USC 1702 – Exemptions These exemptions don’t shield you from the Act’s anti-fraud provisions. Misrepresenting a material fact about the property is a federal violation whether or not registration is required.
Design the Project to Be Financeable
This is where many conversions quietly fail. You can have a beautiful building, clean legal documents, and eager buyers, but if the project doesn’t meet Fannie Mae or FHA eligibility requirements, most of those buyers can’t get a mortgage. Your pool shrinks to cash purchasers, and both sale prices and absorption speed suffer.
Fannie Mae treats newly converted condos differently from established projects and subjects them to a more rigorous Full Review. Plan around these thresholds from day one:
- Presale. At least 50% of total units must be conveyed or under contract to buyers who will use them as a primary residence or second home before Fannie Mae will back mortgages on remaining units. Reaching 50% often requires discounting early units or accepting cash buyers, which cuts into margins.2Fannie Mae. Full Review Additional Eligibility Requirements for Units in New and Newly Converted Condo Projects
- Substantial completion. The project or the legal phase containing the unit must be substantially complete, meaning a certificate of occupancy has issued and all units and buildings in that phase are finished.
- Budget reserves. The HOA’s annual budget must allocate at least 10% of total assessment income to replacement reserves for capital expenditures and deferred maintenance. A reserve study meeting Fannie Mae’s standards can substitute if it shows the project has adequately funded reserves.3Fannie Mae. Full Review Process
- Master insurance. The HOA must carry a master property insurance policy covering common elements and residential structures, endorsed with a condominium association coverage form that includes a waiver of the insurer’s right to recover from individual unit owners.4Fannie Mae.

FHA project approval does not substitute for Fannie Mae’s own review of newly converted projects.5Fannie Mae. FHA-Approved Condo Review Eligibility To capture the widest buyer pool, you need to satisfy both.
Stand Up the HOA and Its Budget
The homeowners association is the legal entity that will manage the common elements and shared finances after you sell the units. Formation typically involves filing articles of incorporation with the state, adopting the bylaws drafted with the declaration, holding an initial organizational meeting, and electing a board. During the conversion period, the developer usually controls the board. State law governs when control transfers to the unit owners, commonly when a specified percentage of units have been sold.
The first operating budget needs to be realistic. It must cover insurance premiums, common-area maintenance, management fees, and reserve contributions. Underestimating the budget to make monthly assessments look attractive is a common temptation that creates serious problems later. If the HOA cannot fund necessary repairs or reserves fall short of Fannie Mae’s 10% threshold, unit values suffer and resale financing becomes difficult.3Fannie Mae. Full Review Process
Several states require the developer to commission a reserve study before the first unit is sold. Even where not mandated, a professionally prepared reserve study signals to buyers and lenders that the finances are on solid footing. The study evaluates the expected useful life and replacement cost of every major building component and recommends an annual funding level to avoid future special assessments.
Split the Insurance Into Two Layers
As a rental building, you likely carry a single commercial landlord policy. After conversion, insurance splits into two layers: a master policy held by the HOA covering the building’s structure and common areas, and individual unit-owner policies covering unit interiors and personal property. Getting the master policy in place before the first closing isn’t optional. Fannie Mae requires it, and so do most state condominium acts.
The master policy must typically be endorsed with a condominium association coverage form that includes a waiver of the insurer’s subrogation rights against individual unit owners.4Fannie Mae. Master Property Insurance Requirements for Project Developments Without that endorsement, a unit owner’s insurer could be forced to contribute to a building-wide claim, complicating both claims resolution and unit sales. Work with a broker experienced in conversions to align the policies with lender requirements and your state’s statutory minimums.
Plan for the Tax Hit
The tax consequences are significant and often poorly understood. The central question is whether the IRS classifies you as an investor or a dealer, because the difference in treatment is dramatic.
Property held as a capital asset and sold after more than one year qualifies for long-term capital gains rates, currently 15% or 20% depending on income. But property held primarily for sale to customers in the ordinary course of business is explicitly excluded from the definition of a capital asset under federal tax law.6Office of the Law Revision Counsel. 26 USC 1221 – Capital Asset Defined Gains on that property are taxed as ordinary income at rates up to 37%.
When you convert an apartment building and sell the units individually, the IRS is likely to view you as a dealer. You are subdividing property and selling multiple units in the ordinary course of a business activity. The agency looks at the frequency and regularity of sales, the extent of improvements made to facilitate the sales, how long you held the property, and whether real estate sales are your primary business. A conversion checks most of those boxes.
Dealer classification carries three consequences beyond the higher rate. Profits are subject to self-employment tax of up to 15.3% on top of ordinary income tax. You cannot use a Section 1031 like-kind exchange to defer the gain. And you may lose deductions available to investors. The combined effective rate for a dealer in a high tax bracket can exceed 50% when federal income tax, self-employment tax, and state income tax are added together.
If you claimed depreciation while operating the property as a rental, the IRS will recapture it when you sell. Recaptured amounts are taxed at ordinary rates, capped at 25% for investors. For dealers, the recapture folds into the ordinary income calculation with no favorable cap. An accountant experienced with real estate conversions should model the full exposure before you commit.
Sell the Units in the Right Order
With the declaration recorded, permits obtained, the HOA established, and insurance in place, you can offer units for sale. Each buyer must receive the public offering statement and all governing documents before signing a purchase contract. Many states give buyers a cooling-off period during which they can cancel without penalty.
Pricing strategy matters more in a conversion than in a typical development because the market already knows the building as a rental. Pricing early units competitively to reach the 50% presale threshold unlocks conventional financing for the remaining units and usually accelerates the entire sellout. Holding out for top dollar on every unit from the start sounds logical but often backfires by keeping the project below the threshold longer than the holding costs justify.
Each closing must comply with state real estate transfer laws, and the seller is responsible for providing all required disclosures about the unit’s condition and the condominium’s financial health. A title company experienced in condominium closings can prepare deeds, transfer documents, and HOA estoppel certificates correctly. Errors in these documents can cloud title and create problems for buyers trying to refinance or resell later.
