Maryland Housing Certainty Act: What It Could Mean for Calvert County Development

By Dawn Riley, Associate Broker, Realtor, Master Certified Negotiator and Pricing Strategy Advisor | Published August 4, 2026

The Maryland Housing Certainty Act aims to make housing approvals more predictable by fixing applicable rules at a substantially complete application and providing a minimum vesting period.

Rules generally lock at application

A housing application is generally evaluated under laws and regulations in effect when the complete or substantially complete application is submitted. Later changes should not move the goalposts for that project, subject to statutory limits.

The completeness deadline

A local authority generally has 35 days to notify the applicant whether the submission is substantially complete. Failure to do so can cause the application to be deemed substantially complete for this purpose.

Five years of vested rights

After all required approvals, the proponent receives a vested right to the authorized use and development for at least five years, or longer if the local authority allows.

Fee timing changes

Certain development excise taxes and impact fees cannot be collected until the project reaches the completion and occupancy points specified by law, with exceptions. That changes cash-flow timing, not necessarily the amount owed.

What this could mean locally

Greater predictability may help approved supply move forward. But the law does not erase Calvert County zoning, environmental review, adequate public facilities, septic limits or other requirements already applicable when the submission is made.

The bottom line

This law deserves attention, but it should not be overstated. My role is to identify the issue early, verify the controlling information and strategically position my client with clear deadlines and documented facts.
