    How to Lease Commercial Space: A Step-by-Step Guide

    Leasing commercial space is a sequence: define the requirement, tour a real shortlist, negotiate a letter of intent, paper the lease, then build out. Rushing the front end is what causes expensive surprises at the back end.

    Key takeaways

    • Start six to twelve months before you need to occupy, longer for buildout-heavy space.
    • Define the requirement in writing before touring — size, budget, must-haves, timing.
    • Negotiate business terms in the letter of intent, not the lease draft.
    • Tenant improvement allowance and free rent are as negotiable as base rent.
    • Tenant representation is typically landlord-paid, so it usually costs you nothing.

    Step 1 — Define the requirement

    Write down square footage range, target occupancy date, maximum total monthly cost, parking needs, power and infrastructure requirements, and any operational must-haves like dock doors, drive-in access or grease traps.

    Include the deal-breakers. A clear requirement turns a scattered search into a short list of real candidates.

    Step 2 — Build a market survey and tour

    A proper survey shows every viable option in the submarket, not just what is easiest to show. Compare rate structure, net charges, escalations, condition and delivery timing side by side.

    Tour the finalists in person. Photos hide ceiling heights, column spacing, loading realities and how a space actually flows.

    Step 3 — Letter of intent

    The LOI is where leverage lives. Base rent, term, free rent, tenant improvement allowance, escalation percentage, renewal and expansion options, and who pays for what all get settled here.

    Run competing LOIs when you have more than one workable option. Landlords price against alternatives.

    Step 4 — Lease negotiation and buildout

    Once terms are agreed, the lease document controls. Pay attention to CAM definitions and caps, maintenance and repair obligations, holdover penalties, assignment and subletting, and personal guaranty language.

    Then plan the buildout honestly: permitting, contractor bids and long-lead materials routinely take longer than expected. Build float into your occupancy date.

    Timeline to plan for

    Simple second-generation space: roughly 60 to 90 days from search to occupancy.

    Space needing meaningful buildout: 120 days and up, sometimes considerably more with permitting.

    Build-to-suit or ground-up: plan in quarters, not weeks.

    Frequently asked questions

    How long does it take to lease commercial space?

    Plan on 60 to 90 days for space needing little work, and 120 days or more when buildout and permitting are involved. Starting six to twelve months ahead gives you negotiating leverage.

    Do I need a broker to lease commercial space?

    You are not required to use one, but tenant representation is typically paid by the landlord out of the listing commission, so most tenants gain an advocate at no direct cost.

    What is a tenant improvement allowance?

    It is money the landlord contributes toward building out your space, usually quoted per square foot. It is negotiable and often trades off against base rent and term length.

    What should I negotiate besides rent?

    Free rent, tenant improvement allowance, annual escalations, CAM caps, renewal and expansion options, exclusivity where relevant, and the scope of any personal guaranty.
