Check the Site Before the Offer: What a Day of Research Saves

Zoning, constraints, utilities and permit history decide what a property can become. Checking them before an offer costs a day. Finding them after closing can cost the plan.

Buyers often learn what a property can become after they own it. The zoning allows less than the listing suggested, a slope or wetland shrinks the buildable area, or a utility cannot serve the plan. Most of that is findable before an offer, in public records, in a day.

What to check

  • Zoning: allowed uses, density, setbacks, height and coverage.

  • Constraints: critical areas, floodplains, slopes, easements and trees.

  • Utilities: water, sewer or septic, power and stormwater.

  • Permit history: open permits, expired permits and unpermitted work.

  • Permit path: which approvals the plan needs and in what order.

What it can reveal

  • A lot that allows two ADUs, or a middle housing land division, that the listing never mentioned.

  • A critical area buffer that cuts the buildable area.

  • An open permit the seller needs to close.

  • A land use review that adds months before a building permit can be filed.

When to do it

Before the offer, or inside the feasibility period. The answer changes the price, the contingencies or the decision itself, and it is cheaper than any of those decisions made blind.
