Tenant Improvement Contractors for a Startup Office Buildout in NYC: Who Runs the Work
On a startup's first custom floor, the tenant improvement contractor is hired in one of two ways: the landlord's contractor builds to an agreed plan, or you hire a contractor the landlord approves and an allowance reimburses part of the cost. In both cases someone on your side has to own the schedule and the budget. Nomad's construction management does that. Design starts while the lease is being negotiated, the build is priced before you sign, and the same team handles filings, landlord approvals and the contractor through to move-in. A custom buildout typically takes 10 to 16 weeks.

Who hires the contractor, and who manages the job
- Landlord build. The owner's contractor builds the space to a plan both sides agree. You trade control for less risk.
- Tenant build. You hire the general contractor. The landlord approves the plans and the contractor, and the building's alteration rules set insurance requirements and working hours.
Hiring and managing are different jobs. A contractor builds what the drawings show. A construction manager works for the tenant: coordinating the architect, the filings, the landlord's reviews and the contractor, and answering for the date and the number.
What Nomad does for a first custom floor, in order
- During the search: a builder's read on each floor you tour, and a test fit on the finalists.
- During negotiation: design begins and the scope is priced, so the allowance you ask for is set against a real estimate.
- At signing: Department of Buildings filings go in and landlord review starts, with long-lead items ordered from the drawings.
- During construction: one team manages the contractor and sits on your side of every change order.
- At the end: furniture, cabling and AV are brought in.
Nomad has 300+ offices delivered and 2M+ square feet leased. Because brokerage and construction management sit in one firm, these steps overlap instead of waiting on each other.
Ten to sixteen weeks, and what moves the date
From a signed lease, design takes two to three weeks, permits and the ordering of long-lead items another three to four, and the construction itself six to nine.
- Decisions: design questions answered within a day hold the short end.
- Landmark review, which adds two to four weeks in SoHo and parts of Flatiron.
- Prewar surprises found at demolition, which cost one to three weeks.
- A single freight elevator shared with the whole building.
- Scope changed after the permit is filed.
Each of these can be assessed before the lease is signed. The buildout cost and timeline guide goes phase by phase.
Questions that predict how a builder will perform
Four questions tell you more than a bid does.
- What were your last three jobs of this size, and may we speak to those clients directly?
- Who will be the site superintendent, by name?
- How is a change order priced and approved?
- What share of your work comes from repeat clients?
Then set terms that keep interests aligned: a guaranteed maximum price once the design is fixed, long-lead purchases shown at cost, a retained share of the payment released only when the punch list is done, and a site walk every week with photos.
What a startup should have ready before work starts
- The headcount you expect in 18 months, and the rooms it implies: about one enclosed room per eight people, plus phone booths.
- One named person who answers design questions within 24 hours.
- The building engineer's letter on power, HVAC hours and freight access.
- A priced scope, so the allowance is argued from a real budget.
- First choices for the slow items: glass, millwork and switchgear.

Can a startup pick its own contractor, or does the landlord decide?
It depends on the deal. In a tenant build you choose, subject to the landlord approving the contractor and the plans. Some buildings also require union trades for certain work, so ask for the alteration rules before you shortlist builders.
When should a contractor first see the space?
Before the lease is signed. An estimate on your actual test fit tells you whether the allowance on offer is enough, and a walk through the floor catches conditions that would slow the job.
Does the allowance cover the contractor's whole bill?
Usually not. Landlords commonly contribute an allowance of $30 to $75 for each square foot on leases of five to ten years, which pays for a third to half of a typical scope. Furniture, cabling and AV normally fall outside it. The allowance entry explains the mechanics.
What happens after we send our headcount, date and budget?
A broker reaches out within the hour during business hours, and a first shortlist can be ready within 24 hours. For a team that needs a custom floor, each floor on it comes with a builder's read and a realistic move-in date, so the calendar is known before you choose.
