What Affects the Cost?

1. Lease Types Explained

Gross lease: fixed monthly rent, landlord pays all building expenses. Net lease (NNN): lower base rent, but tenant pays property taxes, insurance, and maintenance separately (typically adds $5–$15/sqft/year). Modified gross: hybrid. Most retail and industrial leases are NNN; most office leases are gross or modified gross.

2. Market Tiers

Tier 1 (NYC, SF, Boston, DC): Office $50–$120/sqft/year. Retail prime locations: $100–$300+/sqft/year. Tier 2 (Chicago, LA, Seattle, Miami): Office $30–$60/sqft/year. Tier 3 (Phoenix, Nashville, Charlotte): Office $20–$40/sqft/year. Suburban/rural markets: $12–$25/sqft/year.

3. Space Planning Rules

Office: allow 150–200 sqft per employee (open plan) or 200–300 sqft (private offices). Retail: sales floor size depends on product category and foot traffic goals. Warehouse: ceiling height matters — 18–24 ft clear height is standard. Budget an additional 15–20% for common area factor (CAF) added to usable sqft.

Frequently Asked Questions

A 1,000 sqft office in a suburban market costs $1,500–$3,000/month. In a major city (Class B), the same space costs $3,000–$6,000/month. Manhattan Class A office space: $7,000–$12,000/month for 1,000 sqft. Always factor in NNN costs which add 15–40% above base rent.

In a triple net (NNN) lease, you pay base rent PLUS property taxes, building insurance, and maintenance separately. These 'nets' typically add $5–$15/sqft/year above the base rent. If base rent is $20/sqft NNN, your true cost may be $28–$35/sqft/year. Always ask for the full gross-equivalent cost.

Most commercial leases run 3–5 years for small businesses and 5–10 years for larger tenants. Shorter terms (1–2 years) are possible but come at a premium. Longer commitments often get better rates, more TI allowance, and rent abatement (free rent) periods of 1–3 months.

  • ✓ NNN leases add property tax + insurance + maintenance costs (typically $5–$15/sqft more)
  • ✓ Ask for tenant improvement (TI) allowance — landlords often cover $20–$50/sqft in build-out costs
  • ✓ Sublease space can be 20–40% cheaper than direct leases in most markets
  • ✓ Coworking memberships (WeWork, Regus) cost $300–$800/desk/month — cheaper for 1–3 people
