Sizing a New Port Richey apartment at a quarter of the house
Most families want a parent's rooms to be comfortable without swallowing the house. New Port Richey sets that balance for you. Its Land Development Code allows one accessory apartment in a single-family home, only within the principal structure, and caps it at 25 percent of the home's gross floor area. No variances are allowed to accommodate one, so a plan that runs a little over will not be rescued at review. Measure the home, take a quarter, and design to that number from the first sketch, whether the apartment is carved from existing rooms or not.

What in-law suites involves in New Port Richey


What does not count as inside the house in New Port Richey
The boundary is stricter than it sounds. A breezeway or roofed passage does not count as part of the principal structure, so a separate building joined by a covered walk cannot hold the apartment. That rules out the backyard cottage many families picture and points the design toward rooms under the main roof. Pasco County's parent or grandparent reduction is available for a finished suite on a homestead, applied for between January 1 and March 1 with a copy of the final building permit.

New Port Richey accessory apartment questions
Is a backyard cottage for my father allowed in New Port Richey?
Not as a separate home. The city allows an accessory apartment only within the principal structure, and a breezeway or roofed passage does not count. An apartment inside the house is the route to plan.
Can we ask for a variance to make the apartment bigger?
No. New Port Richey's code allows no variances to accommodate an accessory apartment, so the 25 percent cap is firm.
