Development Due-Diligence Checklist

Development Due-Diligence Checklist

Use this before buying land, changing a property’s use, adding units, subdividing, or committing major design dollars.

1. Property & Jurisdiction

  • Confirm legal description, parcel number, ownership, and site boundaries.
  • Identify the city, county, special district, and utility providers with jurisdiction.
  • Confirm current use and whether it is legal, legal nonconforming, or unpermitted.
  • Review easements, covenants, access rights, and recorded restrictions.

2. Zoning & Entitlements

  • Verify zoning and future land-use designation.
  • Confirm the proposed use is permitted, conditional, or prohibited.
  • Check density, lot coverage, height, setbacks, parking, landscaping, and open-space standards.
  • Identify subdivision, platting, rezoning, variance, conditional-use, or design-review requirements.
  • Confirm public-hearing and appeal timelines.

3. Infrastructure & Access

  • Confirm water and sewer availability, capacity, connection points, and fees.
  • Identify frontage, road-improvement, sidewalk, curb, or right-of-way requirements.
  • Review fire access, fire flow, hydrant spacing, and emergency access.
  • Evaluate stormwater, drainage, retention, detention, and downstream constraints.
  • Confirm legal and physical access to the site.

4. Physical & Environmental Constraints

  • Review floodplain and floodway mapping.
  • Check wetlands, critical areas, steep slopes, habitat, or shoreline regulations.
  • Evaluate topography, soils, geotechnical conditions, and retaining-wall needs.
  • Identify environmental contamination or prior uses that may warrant further study.

5. Cost, Schedule & Execution

  • List all known permit, impact, utility, review, and development fees.
  • Identify off-site improvements or mitigation that may be required.
  • Build a realistic approval sequence and schedule.
  • Identify which consultants are needed and when.
  • Confirm financing assumptions can absorb approval delays and cost escalation.

Stop-and-check triggers

Slow down before closing if the project depends on a rezoning, unclear utility capacity, unconfirmed access, major off-site improvements, nonconforming status, floodway issues, or assumptions that have not been verified by the governing jurisdiction.
