What Additional Costs Should I Budget for Besides Base Rent in a Manhattan Office Lease?
When evaluating office space in Manhattan, tenants often focus on the quoted base rent — the $/RSF headline number that brokers and landlords lead with. But base rent is only part of the story. Real occupancy costs are shaped by additional charges that can significantly impact your bottom line. Budgeting for these expenses upfront helps avoid surprises and ensures you understand your true all-in cost per square foot.
Common Additional Costs in Manhattan Office Leases
1. Rent Escalations
- Most leases include annual rent escalations — typically around 2–3% per year.
- These increases are designed to hedge inflation and raise landlord income over time.
- Over a 10-year lease, escalations can add double-digit growth to your rent obligation.
2. Property Tax & Operating Expense Pass-Throughs
- Tenants usually pay their pro rata share of increases in property taxes and operating expenses above a “base year.”
- Operating expenses may include building maintenance, staff, utilities for common areas, and capital repairs.
- It’s critical to ask for historical operating expense data to model your exposure.
3. Utilities
- Heat: Typically included in base rent.
- Electricity: Almost always billed separately — via direct meter, submeter, or fixed inclusion rate (usually $3.00–$4.50 per RSF/year).
- After-hours HVAC: Usually charged hourly, ranging from $50–$150 per hour per unit.
4. Cleaning & Janitorial Services
- In some Class A buildings, standard nightly cleaning is included.
- In others, cleaning is billed separately or outsourced to tenant-selected contractors.
- Special cleaning (server rooms, medical suites) is always an additional charge.
5. Insurance
- Tenants are required to carry commercial general liability insurance, naming the landlord as an additional insured.
- Policies typically cover $2–5 million aggregate liability depending on building class and lease requirements.
- Premiums vary but should be budgeted as part of occupancy costs.
6. Commercial Rent Tax (CRT)
- Unique to Manhattan south of 96th Street, the Commercial Rent Tax applies if your annual rent exceeds $250,000.
- Effective rates range from 3.9% to 6% of base rent.
- Many tenants are caught off guard by CRT — it can add a substantial hidden cost.
Why Tenants Should Calculate “Effective Rent”
The best way to understand your real cost is to request a full-service effective rent estimate from your broker. This number rolls in:
- Base rent
- Escalations
- Tax/operating pass-throughs
- Utilities
- Cleaning
- Insurance
- CRT (if applicable)
Comparing spaces on this all-in $/RSF basis ensures you make an apples-to-apples decision.
