Can I Get a Grant to Build an ADU in Pinellas County?
Yes, if the lot is in St. Petersburg or in downtown Largo: St. Petersburg rebates up to 40% of an ADU's pre-approved construction value for households at or below 120% of area median income, and Largo reimburses up to $8,000 in permit and impact fees for owners who live in its West Bay Drive redevelopment district. In unincorporated Pinellas County the help comes a different way, through waived development review fees on ADUs and a lower property tax assessment when the unit houses a parent or grandparent aged 62 or older.

WHO QUALIFIES?
04 / OTHER PINELLAS CITIES
What about Clearwater, Dunedin or Gulfport?
These three are the programs we could confirm on official city and county pages in September 2026. Other Pinellas cities have their own ADU rules and may offer different incentives. Check with your local planning department before you design or start construction.
Frequently Asked Questions
The program lists "constructing an accessory dwelling unit (ADU)" as eligible work and doesn't say it has to be attached or a conversion. Confirm your specific plan with the city's housing office when you apply, along with the income limit, the $10,000 minimum investment and the licensed-contractor rule.
Not under the county's parent and grandparent reduction. The Pinellas County Property Appraiser limits it to property in unincorporated Pinellas, so an address inside St. Petersburg, Clearwater or Largo doesn't qualify under that ordinance.
No. Largo's redevelopment agency has to approve the grant before any work begins, and the grant reimburses permit and impact fees, not construction costs.
It can. Largo requires an affordable rent on a rented ADU, unincorporated Pinellas only waives its owner-occupancy rule when both units are affordable under a 20-year agreement, and St. Petersburg ties its rebate to the city's workforce and affordable housing requirements, so ask the housing office how a tenant affects eligibility before you sign a lease.
