Home Additions Port St. Lucie

Expand Your Home Without Moving

Whether your family is growing, you're working from home, or you simply need more living space, a custom home addition can be one of the most valuable investments you make in your property. At Gizze Construction, we specialize in designing and building residential additions throughout Port St. Lucie and the Treasure Coast.

From master bedroom additions and family room expansions to garage conversions and accessory dwelling units (ADUs), our team manages the entire process from planning and permitting through construction and final inspections.

A properly designed addition can increase both your home's functionality and long-term property value while allowing you to remain in the neighborhood you already love.

Home Addition Design & Planning

Every home addition starts with understanding the existing structure, lot limitations, zoning requirements, and your long-term goals.

Before construction begins, we evaluate:

  • Property setbacks
  • Lot coverage limitations
  • Building height restrictions
  • Flood zone requirements
  • Utility locations
  • Existing structural conditions
  • HOA requirements
  • Parking requirements
  • Local zoning regulations

Not every property can support every type of addition. Our team works with engineers, architects, and designers to develop solutions that maximize available space while remaining compliant with local building regulations.

ADU Construction & Mother-In-Law Suites

Accessory Dwelling Units (ADUs), guest houses, and mother-in-law suites continue to grow in popularity throughout Florida.

Many homeowners choose ADUs to:

  • Create rental income
  • Provide housing for family members
  • Increase property value
  • Create private guest accommodations
  • Add independent living space

However, ADU regulations vary depending on municipality, zoning district, lot size, utility availability, and local ordinances.

Our team helps homeowners understand:

  • ADU eligibility requirements
  • Zoning restrictions
  • Utility requirements
  • Parking requirements
  • Setback limitations
  • Maximum square footage allowances
  • Permit requirements

Before investing in plans, we help determine whether an ADU is feasible for your property.

Home Addition Permitting Process

One of the most important aspects of any addition project is obtaining the necessary permits and approvals.

Most additions require:

  • Architectural Plans
  • Structural Engineering
  • Energy Calculations
  • Site Plans
  • Permit Applications
  • Building Department Reviews
  • Mechanical Reviews
  • Plumbing Reviews
  • Electrical Reviews
  • Inspections Throughout Construction

The permitting process can be complex and time-consuming, especially when structural modifications are involved.

Gizze Construction helps guide clients through the process and coordinates with local building departments, engineers, and design professionals to keep projects moving forward.

HOA Approval Assistance

Many Port St. Lucie communities require approval from homeowners associations before construction can begin.

We regularly assist homeowners with:

  • Architectural Review Applications
  • HOA Construction Packages
  • Site Plans
  • Contractor Documentation
  • Insurance Certificates
  • Project Schedules

Our experience working with local HOAs helps streamline approvals and reduce delays before construction begins.

Gizze Construction Inc is a full service general contracting company who specializes in new construction additions. Our typical project is in Port St Lucie, Stuart, Jensen Beach, Palm City, Hobe Sound or Vero Beach. We can help you design and budget for any size addition your considering adding to your property. Keeping costs down is what almost every client is looking for and we have the options to provide you to accomplish that.

If you already know what you want to add on without needing us to design for you and just want the costs to build we can help with that. Typical costs for adding square footage to a residential property runs anywhere from $180-$250sqft and up!

When considering the average addition cost in the area expect to pay at least $200 square foot for whatever you want to build. This would be for a room of open space like a bedroom, living room, or an office.

If your trying to add on a kitchen and require new cabinets and counters and everything involved in a kitchen it will rise the square footage costs.

We partner with great engineers and architects locally and we are able to process permits quickly through the building department with residential additions. There are a few standard inspections but overall a very standard process. Locally we always deal with Martin County Building Department, Port St Lucie Building Department, and St Lucie Building Department. With all the construction in our area over the past years all the departments have decent systems in place to process additions quickly
