How Much Office Space Does a 30-Person Team Need?

---

Office space for 30 employees typically requires 3,600–4,500 square feet, based on the standard rule of 120–150 sq ft per person. In NYC, expect to pay $55–$85/sqft/year; in San Francisco, $45–$75/sqft/year. That puts your all-in monthly rent somewhere between $13,500 and $31,875 depending on market and neighborhood. Plan for a 12-month minimum lease and budget an extra 15–20% on top of base rent for things like HVAC, insurance, and buildout.

How Much Office Space Does a 30-Person Team Actually Need?

The most common mistake founders make when sizing office space is underestimating. You're not just fitting 30 desks into a room. You need conference rooms, a kitchen, storage, and enough breathing room for the people you'll hire next quarter.

The standard planning benchmark used by the GSA and most commercial real estate professionals is 120–150 square feet per person of rentable space. For a team of 30, that puts you in the 3,600–4,500 sq ft range.

How Team Type Shifts the Math

Not all 30-person teams are the same:

• Engineering-heavy teams tend to need less per person — closer to 120 sq ft — since most of the day is heads-down at a desk.
• Sales or client-facing teams usually need more (150 sq ft or above) because they burn through conference rooms and private call space fast.
• Hybrid teams can sometimes get away with a smaller footprint if not everyone is in on the same day.

One thing worth understanding before you tour: rentable vs. usable square footage. Rentable sqft includes your share of building common areas — hallways, lobbies, mechanical rooms. Usable sqft is your actual suite. Two spaces listed at 4,000 rentable sqft can feel very different if one has a higher "loss factor." Always ask for the usable sqft when you walk a space.

A good starting point is 4,000 sq ft for most 30-person teams, with room to go up to 4,500 if you're meeting-heavy or want space to grow into. For help thinking through how to size as your headcount changes, see how to estimate office square footage for a scaling team.

What Office Space Costs by Market

Pricing is quoted in dollars per square foot per year ($/sqft/year). To convert to monthly, multiply the annual rate by your square footage and divide by 12.

Example: 4,000 sq ft at $60/sqft/year = $240,000/year = $20,000/month

Here's how costs break down across major startup markets:

These are base rent figures. Always confirm whether a listing is full service gross (most costs included), modified gross (some costs split), or triple net (you pay most operating costs on top). That distinction can add $10–$20/sqft/year in real cost — which on a 4,000 sqft space is $40,000–$80,000 a year.

What Neighborhoods to Look In

Location matters more than founders expect — for recruiting, client perception, and just the day-to-day experience of getting to work. Here's a quick rundown by city.

NYC

• Flatiron / Union Square: The center of NYC's tech startup scene. Inventory moves fast. Rents are high, but recruiting here is easier and the neighborhood sells itself.
• NoMad / Chelsea: A little more room on price than Flatiron, still solid transit. Popular with Series A–B teams that want a real address without paying peak Flatiron rates.
• SoHo / NoHo: Loft buildings with genuine character. Supply is tight and rents reflect that, but the space quality is often worth it.
• Midtown: Better pricing, and the right call if your team commutes from the suburbs or you're doing a lot of client-facing work in finance or professional services.

San Francisco

• SoMa: The default for SF tech startups at this size. Wide variety of floor plates, competitive pricing, and you'll be surrounded by other early-stage companies.
• Jackson Square / Hayes Valley: Boutique spaces with real character. Supply is limited, but when something opens up, it's usually excellent.
• Mission / Dogpatch: Lower rents are genuinely attractive. Transit is more limited, so it works best if most of your team lives nearby and nobody's commuting from the Peninsula or South Bay.

Which Lease Structure Makes Sense at This Size

At 30 employees, you have real options. Picking the right structure matters.

Private Lease

A direct lease with the landlord. You sign an LOI (Letter of Intent), negotiate terms, and the landlord either builds out the space or gives you a TI allowance to do it yourself. Expect a 12–24 month minimum, sometimes longer. You get the most negotiating leverage and the most customization. This is the most common path for teams at your size.

Best for: Teams that want a real home base, expect to grow into the space, and can commit to a longer term.

Sublease

You take over another company's existing lease — usually at a discount because they want out. The term is fixed to whatever's left on their lease, and you'll typically need landlord approval. You can move faster than with a direct lease, but you're inheriting someone else's buildout and working within their timeline.

Best for: Teams that need to move quickly and can live with the existing layout.

Shared Space

A company already in a larger office carves out room for one or two smaller teams. Usually simpler agreements, often month-to-month. At 30 people, the right shared setup is harder to find but not impossible. Less permanence, but also less commitment.

Best for: Teams in a transitional moment — you just hired fast and need space now while you figure out your longer-term plan.

The Hidden Costs to Budget For

Base rent is just the start. Founders consistently underestimate total occupancy cost. Here's what to add on top of your monthly rent:

• Security deposit: In NYC, typically 3 months with a Good Guy Guarantee; 4–6 months without one. SF usually runs 2–3 months.
• HVAC overtime: Most leases cover HVAC during standard business hours (roughly 8am–6pm weekdays). Nights, weekends, and holidays can cost $150–$400+ per hour on top.
• Internet/telecom: Building internet is rarely included. Dedicated fiber for a 30-person team typically runs $400–$1,200/month depending on speed and building infrastructure.
• Furniture: A furnished space avoids upfront capital cost but tends to run more per sqft. An unfurnished space may come with a TI allowance — put it to work. See furnished office space for startups for a full tradeoff breakdown.
• Cleaning: Often not included in modified gross or NNN leases. Budget $800–$2,000/month for a space this size.
• Insurance: Commercial general liability plus property insurance is almost always required by your lease. Typically $1,500–$3,000/year for a space this size.

The rule of thumb: budget 15–20% above base rent to cover these recurring costs without surprises.

What the Leasing Process Actually Looks Like

Finding and signing office space for 30 people is not like renting an apartment. Here's the realistic timeline:

1. Define your requirements (neighborhood, sqft, budget, lease term): 1–2 weeks
2. Tour shortlisted spaces: 2–4 weeks
3. Submit LOI and negotiate terms: 1–3 weeks
4. Lease review and legal markup: 2–4 weeks — get a real estate attorney involved here
5. Buildout or move-in prep: 2–12 weeks depending on the condition of the space

Start to move-in: 8–20 weeks is realistic. If you have a specific date in mind, work backwards from it and start earlier than feels necessary. BLS data on NYC and SF labor markets makes the point clearly: tight labor markets mean contractors and movers book out weeks ahead. You don't want to be the team calling around in week 17 with a hard deadline.

What to Check on Every Tour

Once you're walking spaces, here are the questions worth asking on every single one:

• What's the usable sqft, not just the rentable? Ask for the loss factor explicitly.
• Is HVAC included after hours, or billed as overtime?
• What's actually in the lease? Confirm whether cleaning, electricity, and internet infrastructure are included or not.
• What's the freight elevator situation? For a 30-person move-in, this matters more than you'd think.
• How many conference rooms are there — or can they be built? At 30 people, you want at least two enclosed meeting rooms.
• What's the internet infrastructure? Ask whether the building has a meet-me room and which ISPs have existing runs.
• Is there natural light? Sounds obvious. Interior-facing suites in large buildings can have none.
• What's the standard TI allowance? For teams signing longer leases, landlords often contribute $30–$80/sqft in buildout costs. Know what's on the table before you negotiate.

NYC's commercial lease guidelines are clear that tenants should always get independent legal review before signing. That goes double if you're new to commercial leases and unfamiliar with structures like Good Guy Guarantees or subordination clauses.
