How El Paso Handles Accessory Structures: A Practical Guide
El Paso maintains 169 local ordinances across all categories, and 3 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where El Paso falls on the strict-to-permissive spectrum compared to other cities.
ADU Rules
El Paso allows one accessory dwelling unit per single-family lot under City Code § 20.10.035, detached or attached, capped at 800 square feet (1,200 on lots of 8,000+ sq ft) and one bedroom. Lots need at least 5,500 square feet, and the ADU's height cannot exceed the main house's height.
Key details: ADUs per lot: One (detached or attached). Minimum lot area: 5,500 square feet. Max size: 800 sq ft (1,200 on 8,000+ sq ft lots). Max bedrooms: One bedroom. Detached ADU setback: 10 ft (0-5 ft near alley).
Development Services reviews ADU applications for compliance with § 20.10.035's lot area, size, setback and one-per-lot limits before issuing a building permit; an ADU built without meeting these standards is a Title 20 zoning violation. Under § 20.24.020, violating any Title 20 provision is a misdemeanor carrying a fine of up to $2,000, with each day of noncompliance a separate offense, and § 20.24.010 authorizes the city to pursue injunctive relief.
Shed & Carport Rules
El Paso caps detached residential accessory buildings, sheds, workshops, and freestanding garages, at one story or 15 feet under City Code § 20.10.030(A), and requires at least 60 feet from the front lot line and 5 feet from the main house. Combined accessory floor area is limited to 50% of the house or 40% of the rear yard, whichever is more restrictive.
Key details: Max height: 1 story / 15 feet. Front setback (detached): 60 feet minimum. Setback from main building: 5 feet minimum. Max combined floor area: 50% of house or 40% of rear yard. Always-allowed exception: One building up to 400 sq ft.
El Paso's Development Services Department enforces Title 20 zoning through its permitting and code compliance review; a shed built without meeting the § 20.10.030 setback, height or size limits is a zoning violation. Under City Code § 20.24.020, any violation of Title 20 is a misdemeanor punishable by a fine of up to $2,000, with each day of continuing violation charged as a separate offense; § 20.24.010 also lets the city treat the violation as a nuisance and pursue injunctive relief to force removal or relocation of the structure.
ADU Owner Occupancy
El Paso requires the owner of any lot with a detached accessory dwelling unit to live in either the main house or the ADU as a permanent residence under City Code § 20.10.035(A)(1); an owner may rent out both units only during a temporary absence of one year or less.
Key details: Occupancy requirement: Owner must live in principal unit or ADU. Temporary-absence exception: Up to 1 year, both units rentable. Applies to: Detached ADUs only (§ 20.10.035(A)). Governing section: El Paso City Code § 20.10.035(A)(1).
Development Services can require proof of owner-occupancy, such as a homestead exemption filing or a utility account in the owner's name, when reviewing an ADU permit or investigating a complaint under § 20.10.035(A)(1). Operating a detached ADU as a stand-alone rental without occupying either unit, beyond the one-year temporary-absence exception, is a Title 20 zoning violation; § 20.24.020 makes any Title 20 violation a misdemeanor punishable by a fine of up to $2,000 per day, with § 20.24.010 also allowing the city to seek injunctive relief.
This is one of the stricter rules in El Paso's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
The Bottom Line
El Paso'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 El Paso is broadly strict or permissive.
These rules come from El Paso's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
