Certificate of Occupancy — Free Consultation & Quote

Call or Text 516-399-0139

The Job Isn't Done Until It's Signed Off

A permit is only the start. Most building jobs end with a final inspection and a Certificate of Occupancy (CO) or Certificate of Completion from your town, city or village. Without it, the work can still show up as open or unapproved on your property's record, which can cause problems when you sell or refinance.


We take jobs through to the CO or Certificate of Completion across the Towns of Hempstead, North Hempstead and Oyster Bay, the Cities of Glen Cove and Long Beach, and the villages.

Certificates of Occupancy and Completion: permit records, inspections and final sign-offs

Common Situations

  • You finished a permitted project and need the final inspection and sign-off.
  • You're selling or refinancing, and the buyer's attorney or lender wants the record to match the house.
  • Your older home has no matching certificate of occupancy for what's actually there.
  • A previous owner did work without a permit, and it needs to be legalized before a CO or Certificate of Completion can be issued.
  • A commercial space changed use and needs a new certificate.

What's Involved

  • Records review. We pull your current certificate of occupancy and permit history and compare them to what's on the property.
  • Survey and drawings where the town needs them. We order the survey for you with no markup. Surveys typically run $650–850 for lots under 10,000 sq ft; larger or irregular lots vary.
  • Sign-offs. We coordinate electrical and plumbing sign-offs.
  • Final inspections. We schedule them and follow up until the certificate is issued.

How We Get You to Final Sign-Off

  1. Free consultation. Call or text 516-399-0139, or send your name and phone number, then the property address and what you need.
  2. We compare the record to the house. We find what's open, missing or unpermitted.
  3. We fill the gaps. Survey, drawings, filings and any legalizations.
  4. Inspections. We schedule the town's inspections and handle follow-ups.
  5. Certificate issued. You get your CO or Certificate of Completion.

Timing: simple jobs typically take 2–4 weeks; more complicated jobs typically take 4–8 weeks. It varies by town and scope and is never guaranteed.

CO Questions

What's the difference between a Certificate of Occupancy and a Certificate of Completion?

Both are issued by your municipality after final approval. Which one you get depends on the type of work and your town's process. We'll tell you which applies to your job.


My house is old and the CO doesn't match what's there. Can you fix that?

Yes. We review the records and handle the legalizations and filings needed to bring the record up to date.


Can you get a CO for work that's already finished?

Often, yes, by legalizing the work and taking it through inspections.


Do you handle commercial certificates?

Yes, including after a change of use.
