Building by the Numbers: Lessons from a 1,441-Square-Foot Garage Dispute

Introduction: The High Stakes of Home Improvements

For many homeowners, the ultimate property goal is the addition of a sprawling detached workshop or a custom multi-car garage. However, in communities governed by Homeowners Associations (HOAs), these architectural dreams are often tethered to the cold, hard math of Covenants, Conditions, and Restrictions (CC&Rs). Navigating these rules requires more than just a set of blueprints; it requires a surgical understanding of how your community defines its building limits.

The case of Steven Schmidt v. Catalina Ridge Community Association, Inc., adjudicated before the Arizona Office of Administrative Hearings (OAH), serves as a cautionary tale for any homeowner. What began as a request for a 1,441-square-foot detached garage devolved into a multi-year legal battle over a single mathematical definition. The central conflict? The specific method used to determine the allowable size of an accessory structure.

The Core Conflict: The "40% Rule" Explained

The dispute originated when Petitioner Steven Schmidt proposed a 1,441-square-foot standalone garage. The Catalina Ridge Architectural Review Committee (ARC) denied the project, asserting it exceeded the size limitations set forth in CC&R Article 7.7.

To understand the denial, one must look at the community's "lesser of" formula for accessory structures. Under Article 7.7, a structure is limited to:

• 5% of the total lot area; or
• 40% of the "main Dwelling Unit," whichever is less.

In this case, the Petitioner's lot was approximately 46,300 square feet. A 5% calculation would have allowed for a massive 2,315-square-foot structure. Consequently, the "40% of the main Dwelling Unit" rule became the controlling—and far more restrictive—cap. The entire case hinged on two opposing interpretations of what "Dwelling Unit" actually means:

• The Petitioner’s View: The "Dwelling Unit" should encompass the home's total physical footprint, including livable space, the attached garage, and porches.
• The Association’s View: The "Dwelling Unit" is a legal term referring strictly to the livable, conditioned square footage of the home.

The Calculation Clash: Homeowner Math vs. HOA Math

The following table highlights the significant gap created by these two interpretations. While the Petitioner used a base of 4,438 square feet to justify his project, the ALJ ultimately adopted the Association's more conservative figures.

\Note: While the Petitioner estimated his livable space at 2,820 sq. ft., the ALJ utilized the Association's calculated figure of 2,853 sq. ft. to determine the final legal cap. Under the HOA's math, the proposed 1,441 sq. ft. garage exceeded the limit by nearly 300 square feet.*

The Legal Deep Dive: Definitions Matter

In the courtroom, "common sense" interpretations of space often fail when compared to the specific language of a contract. To resolve the dispute, ALJ Jenna Clark performed a deep dive into the Article I definitions of the CC&Rs, specifically contrasting Section 1.15 (Dwelling Unit) with Section 1.29 (Residence).

The ruling relied on the legal principle of Expressio Unius est Exclusio Alterius—the idea that the express mention of one thing excludes others. The ALJ highlighted Section 1.29, which defines a "Residence" as:

“'Residence' means any subdivided Lot shown on the Plat, together with the residential Dwelling Unit, garage, patio and other Improvements thereon…"

By listing "Dwelling Unit," "garage," and "patio" as separate items in a series, the contract legally establishes them as distinct, mutually exclusive entities. If the "Dwelling Unit" already included the garage and patio, listing them separately would make those words redundant—a violation of standard contract interpretation rules. Furthermore, the Association pointed to Section 7.6, which explicitly excludes garages and porches when establishing minimum livable square footage requirements (2,500 sq. ft.).

The Petitioner argued that if you exclude garages and porches, the community's minimum size requirements become "nonsense" because a house cannot exist as livable space alone. The ALJ rejected this functionalist view, favoring a textualist approach: the document says what it says, regardless of the homeowner's personal logic.

The Final Verdict: Why the ALJ Ruled for the HOA

On July 13, 2022, the Arizona Office of Administrative Hearings (OAH) issued its final decision. ALJ Jenna Clark ruled in favor of the Catalina Ridge Community Association.

The ALJ concluded that under the governing documents, a "Dwelling Unit" is a specific portion of a building intended for residential occupancy and is legally distinct from improvements like garages and patios. Because the Petitioner bore the burden of proof to show the HOA had violated the CC&Rs, and failed to do so, the Association's denial was upheld. The 1,441-square-foot garage was officially denied for exceeding the 1,141.2-square-foot cap.

Key Takeaways for Homeowners

As a consultant, I see these disputes frequently. Here are the strategic lessons to take from the Schmidt case:

1. Livable Area $\neq$ Physical Footprint: In the world of HOAs, your "house" may be 4,000 square feet of stucco and roof, but its "Dwelling Unit" size—the number used for regulatory caps—is likely limited to your conditioned, livable square footage.
2. Definitions Overrule Reality: Do not rely on dictionary definitions or "common sense." Always check the "Definitions" section of your CC&Rs first. If a term like "Residence" or "Improvement" is defined there, that definition is the only one that matters in court.
3. The Burden of Proof Bias: In an administrative hearing, the burden of proof rests on the homeowner. If the contract language is even slightly in favor of the Association’s interpretation, the "tie" effectively goes to the Board unless you can prove a clear, express violation of the rules.

Conclusion: Navigating Your Next Project

The Schmidt case is a sobering reminder that a difference of just 300 square feet can lead to a multi-year legal battle and thousands of dollars in wasted planning. Precise language in community documents exists to maintain neighborhood character and consistency, even when that language leads to difficult math for the individual homeowner.

Before you invest in professional plans or architectural renderings, consult with your Architectural Review Committee (ARC). Ask them specifically for their "base calculation" of your dwelling unit. Understanding the community’s "rules of the road" and their specific definitions is the only way to ensure your project moves from the drawing board to the backyard without a legal detour.
