Off-Street Parking Requirements for the MO-1: Mid-Range Office District
In the City of Dallas MO-1: Mid-range Office District 1, most commercial and residential projects are not assigned a mandatory minimum number of off-street parking spaces unless the property is located within a Modified Delta Overlay (MD-1) or is contiguous to a single-family residential district. When parking is required for a project in the MO-1 District, all spaces must be provided at or below ground level [Section 51A-4.121(c)(5)].
General Parking Framework in the MO-1 District
The City of Dallas Development Code generally treats the MO-1 District as a "none required" zone for basic parking counts, shifting the burden to specific overlay regulations or adjacency protections. For the residential uses permitted in this district—specifically college dormitories, fraternities, and sororities—the baseline requirement for off-street parking is zero [Section 51A-4.209(b)(1)(C)].
However, these exemptions do not apply if the City of Dallas has designated the area as a Modified Delta Overlay (MD-1). Furthermore, if a commercial use in the MO-1 District is contiguous to a single-family district, the City of Dallas imposes specific ratios based on the square footage of the structure [Section 51A-4.301(a)(2)(B)].
Commercial and Office Parking Ratios
For commercial projects in the MO-1 District, requirements are determined by the classification of the use and the presence of the MD-1 Overlay.
Table 1: Parking Ratios for MO-1 Projects in the MD-1 Overlay
| Use Category | Required Parking Spaces |
|---|---|
| Office | 1 space per 333 square feet of floor area |
| Financial institution without drive-in window | 1 space per 333 square feet of floor area |
| Medical clinic or ambulatory surgical center | 1 space per 200 square feet of floor area |
| Restaurant without drive-in/drive-through (Main Use) | 1 space per 100 square feet of floor area |
| Personal service use | 1 space per 200 square feet of floor area |
[Table 1.2.1; Table 1.2.2; Section 51A-4.210(b)(24)]
Table 2: Parking Ratios for MO-1 Projects Contiguous to Residential Districts
If an MO-1 District project is contiguous to a City of Dallas single-family district, the following minimums apply even if the property is not in an overlay:
| Commercial Use Category | Minimum Off-Street Parking Requirement |
|---|---|
| Technical school | 1 space per 500 square feet of floor area |
| Medical or scientific laboratory | 1 space per 500 square feet of floor area |
| Catering service | 1 space per 500 square feet of floor area |
| Electronics service center | 1 space per 500 square feet of floor area |
| Custom business service | 1 space per 500 square feet of floor area |
[Table 1.1]
Residential Parking Requirements
The primary residential use permitted in the MO-1 District is college dormitory or sorority/fraternity housing. For these specific residential projects, the City of Dallas specifies a requirement of "None" [Section 51A-4.209(b)(1)(C)].
If the MO-1 District project involves a "Residential Hotel" (permitted by right in some MO(A) districts), it is also generally exempt from a minimum count unless the site-specific SUP or overlay dictates otherwise [Section 51A-4.209(b)(5.1)].
Design and Location Standards
The City of Dallas mandates specific design constraints for any parking provided within the MO-1 District:
- Vertical Placement: All off-street parking must be provided at or below the ground level [Section 51A-4.121(c)(5)].
- Loading Spaces: Off-street loading spaces for commercial uses cannot be located in the required front yard. They may be placed in the front yard only if they are behind the setback line and screened from the street by a fence or hedge at least six feet in height [Section 51A-4.121(c)(5)(B)].
- Adjacency Screening: If an MO-1 building or parking structure is erected across an alley from a residential district, any portion of the site directly across from that district must be screened [Section 51A-4.121(c)(8)(E)].
