Formula
Parking Ratio:
Parking Ratio = Number of Parking Spaces / Building Area (sq ft)
Spaces per 1,000 sq ft:
Spaces per 1,000 sq ft = Parking Ratio × 1,000
Spaces per 10,000 sq ft:
Spaces per 10,000 sq ft = Parking Ratio × 10,000
Example 1: Office Building
Parking Spaces: 100, Building Area: 50,000 sq ft
Parking Ratio: 100 / 50,000 = 0.0020 spaces/sq ft
Per 1,000 sq ft: 0.0020 × 1,000 = 2.0 spaces
Per 10,000 sq ft: 0.0020 × 10,000 = 20.0 spaces
Example 2: Retail Store
Parking Spaces: 200, Building Area: 40,000 sq ft
Parking Ratio: 200 / 40,000 = 0.0050 spaces/sq ft
Per 1,000 sq ft: 0.0050 × 1,000 = 5.0 spaces
Per 10,000 sq ft: 0.0050 × 10,000 = 50.0 spaces
Note: Retail typically requires more parking per square foot

Frequently Asked Questions
What's a typical parking ratio?
Typical parking ratios vary by property type: Office buildings 2-4 spaces per 1,000 sq ft, Retail 3-5 per 1,000 sq ft, Restaurants 10-15 per 1,000 sq ft, Residential 1-2 spaces per unit. However, ratios vary significantly by location, local regulations, and property specifics.
How do I find parking ratio requirements?
Check local zoning codes, building codes, or planning department requirements. Many cities have minimum parking ratio requirements based on property type and use. Contact your local planning department or review zoning ordinances for specific requirements.
Should I include accessible parking spaces?
Yes, include all parking spaces including accessible (handicapped) spaces. Accessible spaces are required by law and should be included in total parking count. They're typically a percentage of total spaces based on ADA requirements.
What building area should I use?
Use gross leasable area (GLA) for commercial properties, or total floor area as specified by local regulations. For residential, use total unit square footage or number of units. Check local requirements - some jurisdictions specify which area measurement to use.
Can parking ratio be too high?
Yes, excessive parking can be wasteful and costly. Over-parking uses valuable land, increases construction costs, and may not be necessary. Many modern developments are reducing parking ratios, especially in urban areas with good transit access. Balance between requirements and practical needs.
How do parking ratios differ by location?
Parking ratios vary significantly by location. Urban areas often have lower requirements (better transit, walkability), while suburban areas typically require more parking. Central business districts may have different requirements than residential areas. Always check local regulations for your specific location.
