Condo vs Townhouse HOA: Key Differences for Buyers

Condo and townhouse are not opposites. "Townhouse" describes architecture; "condo" describes a legal ownership structure. The recorded declaration determines which set of rules apply: condo buyers own a unit plus an undivided share of common elements, while most townhouse buyers own the lot and the structure on it. The classification drives HOA scope, insurance, reserves, and critically, how Fannie Mae and Freddie Mac underwrite your loan.

The most expensive mistake buyers make in this category is assuming the architectural style of a unit determines its legal and financing treatment. It does not. A four-story building with attached units that looks like a row of townhouses can be legally organized as a condominium ("horizontal property regime"). When that's the case, the lender treats it as a condo project and applies the full warrantability gauntlet, including the delinquency cap, master-insurance sufficiency, and reserve funding rules under Fannie Mae's 2026 condo rules.

The Legal Distinction (Read the Declaration, Not the Roof)

Condo owners hold a defined unit plus an undivided interest in common elements. Townhouse owners typically hold fee-simple title to a lot. The recorded declaration controls.

Condo (statutory creature). Florida Statute §718.103 defines a condo unit as "a part of the condominium property which is subject to exclusive ownership," with each unit holding "an undivided share in common elements." California Civil Code §4185 defines "separate interest" in a condo as the "separately owned unit." The walls-in rule is standard: when walls, floors, or ceilings are boundaries, the interior surfaces are part of the unit owner's separate interest, and everything past those surfaces is a common element owned collectively.

Townhouse (typically a planned development). Owner holds fee-simple title to the lot and the structure on it, often including the land underneath. Party walls between units are usually shared by easement or covenant. Texas illustrates the test: under TUCA Chapter 82 (condominium), the deed references a unit number with an undivided interest in common elements. Under Chapter 209 (POA), the deed describes a lot and block with no undivided common-element share.

Bottom line: read the recorded declaration during due diligence. If it includes the words "horizontal property regime," "condominium," or "undivided interest in common elements," it's a condo regardless of what the building looks like.

What the HOA Actually Maintains

Condo HOAs are statutorily responsible for common elements including roof, exterior, and structural systems. Townhouse HOA scope is entirely CC&R-driven and varies widely.

Condo HOA scope is set by statute and by the declaration. Florida §718.113(1) makes maintenance of the common elements an association duty. In practice, this typically includes roof, exterior walls, hallways, structural components, elevators, often the building's domestic water and waste lines, and master insurance. The unit owner is responsible for everything inside the walls-in boundary.

Townhouse / PUD HOA scope is whatever the declaration says. The range goes from minimal (clubhouse, pool, landscaping in common areas) to nearly condo-level (roof, siding, "outside the studs"). Read the maintenance allocation section of the declaration carefully. If it pushes roof replacement onto individual owners, the buyer is taking on potentially six-figure infrastructure exposure that a condo buyer in the same building would not have.

Insurance: Two Different Models

Condos use a master + HO-6 two-policy model. Townhouses typically use a single HO-3 policy. The condo loss-assessment endorsement is where most buyers are underinsured.

Condo: master + HO-6

The condo association carries a master policy covering the building exterior, common elements, and liability for common areas. The unit owner carries an HO-6 ("walls-in") policy covering interior finishes, personal property, liability, and critically, loss assessment.

Loss assessment is the line item that catches buyers off guard. The default loss-assessment endorsement on most HO-6 policies is small (typically $1,000, sometimes $2,000). It pays the owner's share when the master policy doesn't fully cover a common-element loss. After the post-2024 condo insurance crisis, master-policy deductibles routinely run $25,000 to $100,000+ per claim. Industry guidance is to raise loss assessment to $25,000-$50,000, but even raised limits often cap reimbursement of the master deductible at $1,000 unless you specifically endorse coverage for that scenario.

Townhouse: single HO-3

The townhouse owner typically carries an HO-3 standard homeowners policy covering the entire structure and the land, similar to a single-family home. The HOA's master policy, if any, usually covers only common amenities (clubhouse, pool, common area liability). When the HOA insures shared roofs or party walls, coordination gaps between the HOA policy and each owner's HO-3 are common and worth verifying with both insurers.

Reserve Studies: Different Stakes

Condo reserves are typically much larger because the HOA owns structural components. SIRS and milestone-inspection rules in Florida apply to condos, not to townhouses.

Both condo and PUD/townhouse HOAs are usually subject to a reserve-study requirement. California Civil Code §5550 covers both: visual inspection at least every three years, annual review. The differences show up in what the reserves are funding.

• Condo reserves typically include roof, elevators, façade, plumbing risers, building envelope, and common-area amenities. The dollar magnitude is correspondingly large. Florida's Structural Integrity Reserve Study under §718.112(2)(g) applies to condo and cooperative buildings three or more habitable stories tall, with the deadline tied to milestone inspections.
• Townhouse reserves typically include amenities, fencing, paving, and shared landscaping. Where the HOA owns roofs or party walls, those are also funded. The dollar magnitude is smaller per association, but the vulnerability is that townhouse HOAs more commonly have inadequate reserves and rely on owners to maintain their own roofs without funding plans.

For either type, the metric to focus on is percent funded, and the ground-truth document is the reserve study.

Financing: PUD vs Condo Project (Where Buyers Get Surprised)

Fannie Mae classifies projects by the recorded declaration, not architecture. Condo projects face a heavier warrantability review than PUDs.

This is the distinction that drives more lender surprises than anything else in this category. Per Fannie Mae Selling Guide B4-2.1-01 (May 6, 2026 update), zoning is not a basis for classifying a project. Fannie classifies as a condo project any development declared or filed as a "horizontal property regime," unless local statute permits a horizontal regime to be created as a PUD AND the legal documents explicitly say "PUD."

The two paths split there:

• Classified as a condo project → subject to Fannie Selling Guide B4-2.1 / B4-2.2, including Lender Letter LL-2026-03 reserve threshold (10% of operating budget today, rising to 15% on January 4, 2027), the 15% delinquency cap on units 60+ days past due, master-insurance sufficiency review, and the single-entity-ownership cap. This is the full "warrantability checklist."
• Classified as a PUD → subject to Fannie Selling Guide B4-2.3-01, which has substantially lighter project-level review requirements and treats the property more like a single-family home with HOA covenants.

The lender's appraiser determines classification based on the recorded documents, not the architectural style. An attached three-story townhouse-style unit can be either a PUD (lighter review) or a condo (heavier review). The recorded declaration is the deciding factor.

Side-by-Side Summary

The same property characteristics often matter for both, but the magnitude and rulebook differ.

Five Buyer Red Flags

Architectural townhouse legally a condo. Underfunded shared roofs. Default HO-6 loss assessment. Mismatched maintenance expectations. Florida 3+ story townhouse-style condo subject to SIRS.

1. Architectural townhouse that's legally a condo. Buyer applies for a "regular house mortgage" assuming PUD treatment; lender's appraiser pulls the recorded declaration, reclassifies as condo, and the loan goes through the heavier warrantability review. Deals fall through or reprice late.
2. Townhouse HOA owns shared roofs but is underfunded. The HOA owns the roof, the reserve study calls for replacement in 5 years, and the funded percentage is below 30%. A surprise special assessment lands shortly after closing.
3. Default $1,000 HO-6 loss assessment. Master policy has a $50,000 deductible after a hurricane or pipe burst; your loss-assessment endorsement caps reimbursement at $1,000. Out of pocket for the rest.
4. Mismatched maintenance expectations. Buyer assumes "townhouse means like a house" and that they can proactively replace the roof, repaint, or change the front door. The declaration says the HOA controls all of those. Less freedom than expected.
5. Florida 3+ story townhouse-style condo. Subject to SIRS and milestone-inspection rules under §718.112(2)(g). The same building structured as a PUD would not be. Recorded declaration is the determining factor.
