How to Start Looking for Commercial Space for Your Business

How much space you need, what to budget, how long it takes, and who works for you. Plain answers for business owners in Ventura and Santa Barbara County.

Every space search starts the same way. Somebody drives past an empty storefront, sees a phone number on a sign, and thinks, “That could be us.” It’s a great feeling. It’s also the exact moment most business owners hand the entire negotiation to the one person in the conversation who is paid to work for the landlord.

We see it every week in Ventura and Santa Barbara County. And we get it personally, because one of us pays commercial rent every month for The Bennery on Santa Clara Street. Before you tour anything, you need a game plan. Here are the first seven questions business owners ask, answered straight.

Question 1 of 50

How do I start looking for commercial space for my business?

Short answer: Start with numbers, not listings. Define your budget as a share of projected revenue, your square footage range, your must-have features (parking, plumbing, power, visibility), your target areas, and your opening date. Then bring in a tenant representative before you call any listing agent.

The order matters more than people think. Here is the sequence that protects you:

  1. Set your occupancy budget. Total monthly cost, not just base rent (see Question 3).
  2. Size the space. A realistic square footage range from your operations, not a guess.
  3. List your non-negotiables. Zoning, parking, plumbing, power, ceiling height, signage, foot traffic.
  4. Pick your target areas. Two or three submarkets where your customers already are.
  5. Work backward from opening day. Permits and buildout often take longer than the search itself.
  6. Get representation first. Once you call the number on the sign, you are talking to the landlord’s agent.

Question 2 of 50

How much commercial space do I need?

Short answer: Size your space from how your business actually operates. Common starting points are 150 to 250 square feet per person for office, 15 to 20 square feet per seat for restaurant dining areas, and around 35 square feet of indoor space per child for licensed childcare in California. Then add room for storage, restrooms, and 3 to 5 years of growth.

Business type
Common starting point

Professional office

150 to 250 SF per person, plus conference and storage

Restaurant

15 to 20 SF per dining seat; kitchen and back of house often 30 to 40% of total

Medical or dental

Driven by number of exam rooms or operatories plus waiting and sterilization

Licensed childcare (California)

35 SF usable indoor space per child and 75 SF outdoor per child

Retail

Driven by merchandise display, stockroom, and checkout flow

Industrial

Driven by equipment footprint, racking height, and truck access

These are planning numbers, not rules. The mistake we see most is leasing for today. Signing a five-year lease on a space you’ll outgrow in eighteen months is its own kind of expensive.

Question 3 of 50

How much should I budget for commercial rent?

Short answer: Budget for total occupancy cost, which is base rent plus NNN or CAM charges, utilities, insurance, and maintenance. Many restaurants aim to keep occupancy cost around 6 to 10 percent of gross sales, and many retailers target roughly 10 to 15 percent. If the numbers only work in your best month, the space is too expensive.

The number on the flyer is almost never the number you pay. A space listed at $2.00 per square foot per month NNN might carry another $0.60 to $1.00 per square foot in pass-through charges, depending on the property. On 2,000 square feet, that gap alone can be $1,200 to $2,000 a month.

Build your budget from your revenue projections up, not from the listing down. Our deep dive on total occupancy cost walks through the full math.

Question 4 of 50

How long does it take to find and lease commercial space?

Short answer: For office and retail, plan on 3 to 6 months from first search to move-in. For restaurants, medical, childcare, and any space needing major buildout or permits, plan on 6 to 12 months or more. Start looking at least 6 to 9 months before you need to open or before your current lease ends.

Phase
Typical time

Search and tours

2 to 8 weeks

LOI negotiation

1 to 3 weeks

Lease drafting and review

2 to 6 weeks

Plans, permits, and plan check

1 to 6 months (longest for food, medical, childcare)

Buildout

1 to 4 months

If you already have a lease, your renewal option notice deadline is often 6 to 12 months before expiration. Miss it and you may lose the option entirely. That date belongs on your calendar today.

Question 5 of 50

Do I need a commercial real estate agent to lease space?

Short answer: You are not legally required to have one, but going without representation means the only licensed professional in the deal works for the landlord. A tenant representative finds options, compares true costs, negotiates rent, concessions, and lease terms, and coordinates the process on your behalf.

Roughly 85 percent of small business owners sign commercial leases without their own representation. That’s like walking into a playoff game where the other team has a coach and you’re calling your own plays from the stands.

A tenant rep’s job is to:

  • Search listed and off-market space across your target areas
  • Compare spaces by total occupancy cost, not headline rent
  • Negotiate rent, free rent, tenant improvement allowance, and term
  • Push back on clauses like personal guarantees and relocation rights
  • Keep the timeline moving through LOI, lease, permits, and delivery

Question 6 of 50

How much does a tenant rep broker cost?

Short answer: In most commercial lease deals, a tenant representative costs the tenant nothing. The landlord pays the leasing commission, which is typically already budgeted into the listing and split between the landlord’s broker and the tenant’s broker.

When a landlord lists a space, they sign an agreement with their broker that sets the commission. That agreement usually anticipates a cooperating broker on the tenant side. If you don’t bring one, the listing broker often keeps the full commission. Either way, the cost is already in the deal. Having representation just decides whether any of it works for you.

Question 7 of 50

What's the difference between a tenant rep and the listing agent?

Short answer: The listing agent represents the landlord and has a duty to get the landlord the strongest possible terms. A tenant representative works only for you, with a duty to get you the strongest possible terms. In California, agents must disclose who they represent in writing.

Frequently asked questions

Does The Lease League represent landlords?

Should I call the number on the For Lease sign?

Call us first. The number on the sign reaches the landlord’s agent, and that conversation can shape your deal before you have anyone on your side.

Is it too early to talk to a tenant rep if I'm still writing my business plan?

No. Knowing realistic rents and space sizes early makes your business plan and loan application stronger.

So where are you in the process right now: still dreaming, running numbers, or already driving past storefronts?
