Description

Before you plat it, survey it, or design around it, one question decides everything: does this actually count as a subdivision at all? 

Get that wrong, and the wrong process follows you the whole way. 

Deny the final plat, and preliminary approval doesn’t survive it. The plat, the survey, the design: all of it, again. 

Add a housing type with its own foundation, setback, and utility rules, or a purchaser who finds the parcel was never approved. 

 

That’s why we put together this training… 

…to keep your plats, your approvals, and your license safe from ground that keeps shifting under you. 

 

You’ll leave this training knowing how to: 

  • Determine whether your project actually counts as a subdivision, not just what it looks like on paper 
  • Tell which parts of subdivision law the state sets, and which your locality writes on its own 
  • Match your foundation, setback, and utility plan to stacked homes, condos, or manufactured housing, not a standard lot 
  • Match your plan to the zoning and density rules that actually govern it 
  • Know what a purchaser can claim on an unapproved parcel 
  • Handle subdivision and condo enforcement the way the law requires, not the way that gets your plat vacated 

 

Learn from Carol A. Sigmond, a distinguished attorney with four decades of experience litigating disputes just like these. 

 

One missed step can send a subdivision back to square one – or undo it. 

 

This training is your shot to get the sequence right, before a purchaser or a denial comes back on you.
