5 Things to Check Before Buying Land (That Most People Skip)

The Most Expensive Mistakes Happen Before Closing

Real estate professionals have a saying: "You make your money when you buy, not when you sell."

The corollary nobody mentions: you lose your money when you skip due diligence.

Here are the 5 checks that separate smart land buyers from people writing $50K-$500K checks based on vibes and a Zillow listing.

1. Zoning — Not Just the Code, the OVERLAYS

Everyone checks the base zoning. "It's R-1, great, I can build a house."

But overlays change everything:

• Historic preservation overlay → design review, materials restrictions, 6+ month hearings
• Coastal zone overlay → additional permits, height restrictions, setback multipliers
• Wildfire hazard overlay → fire-resistant materials, defensible space, access road standards
• Airport noise overlay → sound insulation requirements, height restrictions

The base zoning says "yes." The overlay says "yes, but..."

Buildability™ checks all overlay districts automatically and flags them in your Buildability Score™.

2. Flood Zone — The $40,000/Year Surprise

FEMA flood zones are not binary. There's a massive difference between:

• Zone X (minimal risk): No flood insurance required. Build normally.
• Zone AE (100-year floodplain): Flood insurance required (~$2,000-$5,000/yr). Must elevate.
• Zone VE (coastal high hazard): Flood insurance required (~$8,000-$40,000/yr). Extreme elevation and construction requirements.

The difference between Zone X and Zone VE on the same street can be $40,000/year in insurance costs. That's not a rounding error — that's a deal-killer.

Buildability™ checks FEMA flood zone data instantly for any address.

3. Setbacks — Your Lot Is Smaller Than You Think

You buy a 10,000 sqft lot. You think you have 10,000 sqft to build on. Wrong.

After setbacks:

• Front: 25 ft
• Rear: 20 ft
• Each side: 5 ft

On a typical 50' x 200' lot, that leaves you with a 40' x 155' buildable area = 6,200 sqft.

You just lost 38% of your lot to setbacks. And that's before parking, open space, and lot coverage limits.

Buildability™ calculates your actual buildable area based on your specific zone's setback requirements.

4. Utility Access — The $200,000 Assumption

"Utilities are at the street." Great. But:

• Water main at the street ≠ guaranteed connection capacity
• Sewer at the street ≠ capacity for your project's flow
• Electric at the property line ≠ adequate service for your intended use

In some cases, extending or upgrading utilities can cost $50,000-$200,000. That cost rarely shows up in a listing or a basic zoning check.

Buildability™ verifies utility availability and service readiness as part of the Infrastructure dimension.

5. Permit Timeline — The Calendar Nobody Checks

Here's a timeline nobody tells first-time land buyers:

Step	"Simple" Project	Complex Project
Pre-application meeting	2-4 weeks	2-4 weeks
Plan preparation	4-8 weeks	8-16 weeks
Plan check / review	4-8 weeks	8-24 weeks
Corrections + resubmit	2-4 weeks	4-12 weeks
Permit issuance	1-2 weeks	2-4 weeks
Total	13-26 weeks	24-60 weeks

That's 3-14 months of carrying costs (mortgage, taxes, insurance) before you break ground. At $2,000-$5,000/month in carrying costs, that's $6,000-$70,000 in time cost alone.

Buildability™ estimates your specific permit timeline and approval friction as part of the Buildability Score™.
