Denton's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Denton, Texas, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Tiny Homes

Denton caps backyard accessory dwelling units at 800 square feet or 75% of the main home's size, whichever is greater, and allows just one per lot on qualifying residential properties.

Key details: Max ADU size: 800 sq ft or 75% of home. Per-lot limit: One ADU (SUP for a second). Detached ADU location: Side or rear yard only. Utilities: No separate water or sewer service. Entrance: Separate exterior entrance required.

Building an ADU without a permit, or one that exceeds the 800-sq-ft/75% cap or violates setback and design standards, puts the property out of compliance with the Development Code and can lead to permit denial or code enforcement action.

Shed & Carport Rules

Denton's zoning code confines sheds and other accessory structures to the rear yard, requires a 3-foot setback from every property line, and bars them from sitting in any easement.

Key details: Setback: 3 feet minimum from all property lines. Location: Rear yard only, limited exceptions. Easements: No accessory structure may encroach. Appearance: Must match house or be screened.

Placing a shed in the front or side yard, inside the 3-foot setback, or over an easement violates DDC Section 5.4.3 and can draw a code enforcement order to relocate or remove the structure.

ADU Rules

Denton allows one accessory dwelling unit per lot, sized up to 800 square feet or 75 percent of the primary home's floor area, whichever is greater, under the Denton Development Code.

Key details: Max size: 800 sq ft or 75% of home. ADUs per lot: One by right. Second ADU: Requires Specific Use Permit. Utilities: No separate water/sewer tap. Entrance: Separate exterior entrance required.

Building or converting space into an ADU without meeting these standards, or without the required permits, exposes the owner to code enforcement action, denial of certificate of occupancy, and orders to remove or modify the unit.

The Bottom Line

Denton's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Denton is broadly strict or permissive.

Keep in mind that Denton can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
