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..."

ReadyPermit 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.

ReadyPermit 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.

ReadyPermit 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.

ReadyPermit 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.

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