Building Type Standards

office Building Standards

Office buildings typically require moderate parking due to regular business hours and employee needs.

Minimum:
2-3 spaces per 1000 SF
Typical:
3-5 spaces per 1000 SF
Premium:
4-6 spaces per 1000 SF

Recommendations & Insights

Consider if this high ratio is necessary - may be overbuilding parking
High ratio suitable for retail, restaurant, or suburban locations

Example: Apartment Building

Building Specifications

Building Type: Apartment Complex

Total Rentable Area: 25,000 square feet

Planned Parking Spots: 100 spaces

Location: Suburban area

Calculation Process

Formula: Parking Ratio = (Parking Spots ÷ Area) × 1000

Calculation: (100 ÷ 25,000) × 1000 = 4.0 spaces per 1000 SF

Area per Spot: 25,000 ÷ 100 = 250 SF per parking space

Assessment: Moderate ratio, suitable for suburban apartments

Understanding Parking Ratios

What is a Parking Ratio?

  • Definition: Number of parking spaces per unit area
  • Standard: Usually expressed as spaces per 1000 SF
  • Purpose: Ensures adequate parking supply
  • Planning: Critical for development approval

Key Considerations

  • Building Use: Different uses require different ratios
  • Location: Urban vs. suburban requirements vary
  • Transit: Good transit reduces parking needs
  • Demographics: User patterns affect requirements

Formula & Calculation

Parking Ratio = (Number of Parking Spots ÷ Rentable Area) × 1000

Example:
100 spots ÷ 25,000 SF × 1000 = 4.0 spaces per 1000 SF

Planning Benefits

  • Ensures regulatory compliance
  • Optimizes development costs
  • Improves user experience
  • Supports sustainable development
