St. Petersburg homes are aging. The bones are solid. But the layouts, kitchens, and bathrooms were built for a different era. A luxury home renovation in St. Pete takes what is already there and turns it into a home that works the way you actually live.

At One Clearwater Construction, full-home renovation projects combine kitchen upgrades, master suite additions, bathroom transformations, and room expansions under one licensed contractor and one permit process. The result is a coordinated build rather than a patchwork of separate jobs.

This guide covers estimated costs by scope, what drives your final number, and how OCC approaches a multi-room luxury renovation in St. Petersburg and Pinellas County.

What Is a Luxury Home Renovation in St. Petersburg, FL? 

A luxury renovation is not just high-end finishes. It is a project that changes how a home functions — not just how it looks.

St. Pete’s older neighborhoods are full of well-built homes with outdated interiors. The square footage is there. The location is right. But a galley kitchen, a single-car garage, or a cramped master bath is holding the home back. A full-scope renovation fixes all of that in one coordinated project.

Here is what a luxury renovation in St. Pete typically includes at One Clearwater Construction:

• Full kitchen transformation — custom cabinets, stone countertops, open layout changes
• Master suite expansion or ground-floor addition with a private bath
• Bathroom upgrades across the home — custom tile, walk-in showers, soaking tubs
• Room additions for square footage the existing footprint cannot provide
• Second-story additions for growing families or income units
• Coordinated permits, inspections, and engineering letters for the full project

Every scope listed above is something OCC manages from permit application through final walkthrough. You work with one contractor, not six.

If you are also considering outdoor upgrades as part of the broader renovation, our outdoor living space Clearwater, FL page covers how OCC integrates those into the same project scope.

Estimated Cost by Renovation Scope

All pricing below comes from One Clearwater Construction’s published rates. These are estimated ranges, not fixed quotes. Your final number depends on scope, existing conditions, material selections, and site factors specific to your St. Pete property.

Here is a full breakdown across the main renovation categories:

Renovation Scope	Estimated Cost (OCC)
Full Kitchen Remodel	$25,000 to $60,000
Cabinet Refacing or Door Replacement	$10,000 to $20,000
Standard Bathroom Remodel (5×8)	$12,000 to $15,000
Mid-Range Bathroom	$15,000 to $22,000
Master Bathroom	$15,000 to $35,000
First-Floor Master Suite Addition	$60,000 to $100,000
Second-Story Addition	$200 to $250 per sq ft
Garage Conversion	$80 to $120 per sq ft

Combining scopes under one project typically saves on permit costs and trade mobilization. A kitchen and master bath done together under one permit package costs less in total than running them as two separate projects six months apart.

Every OCC project starts with a detailed written estimate. The price quoted is the price paid. No line items added after signing and no end-of-project surprises.

Kitchen Renovation — What OCC Builds

The kitchen is always the centerpiece of a luxury renovation. It is the most-used room in the home and the one that drives the most value at resale.

At OCC, kitchen renovation runs from cabinet refacing through full open-concept transformations. Here is what each tier delivers:

Cabinet Refacing or Door Replacement

The most efficient way to change how a kitchen looks without replacing everything.

Estimated cost at OCC: $10,000 to $20,000

This scope is right when the existing cabinet boxes are structurally sound. Here is what it includes:

• New cabinet doors and drawer fronts throughout
• Exposed surfaces wrapped or refinished to match
• New hardware installed — soft-close throughout
• Works within the existing footprint without plumbing or electrical changes
• Timeline: 4 to 6 weeks after permit issuance

This scope delivers a full visual transformation at a fraction of the cost of a full gut-and-rebuild.

Full Kitchen Remodel

Everything replaced. Cabinets, countertops, flooring, lighting, electrical, and plumbing coordinated under one scope.

Estimated cost at OCC: $25,000 to $60,000

This is the right path when the current layout does not work or when multiple systems are outdated. Here is what OCC builds:

• Full demo and disposal of existing kitchen
• Custom cabinet design — full-overlay doors, dovetail drawer boxes, soft-close hardware
• Quartz or granite countertops — templated, fabricated, and installed
• Open-concept layout changes, including load-bearing wall assessment and header work
• Dedicated electrical circuits, gas line extensions, and PEX plumbing upgrades
• Porcelain tile or luxury vinyl plank flooring throughout
• Recessed LED lighting, under-cabinet LED strips, and tile backsplash

OCC supplies cabinets and countertops through Pinellas County trade accounts, keeping material costs below retail showroom pricing for the same quality level.

Master Suite and Bathroom Renovation

A master bath renovation is the second most impactful upgrade in a luxury renovation. Done right, it transforms the daily experience of the home.

Here is how OCC’s bathroom tiers compare across scope and cost:

Bathroom Scope	What’s Included	Estimated Cost
Standard 5×8 Remodel	Tile, vanity, shower	$12,000 to $15,000
Mid-Range Bath	Walk-in shower, custom tile	$15,000 to $22,000
Master Bathroom	Double vanity, walk-in shower, soaking tub	$15,000 to $35,000

Each tier at OCC includes full permit handling, all inspections, and demo through final fixture installation. You never coordinate separately with the county.

What a Master Bathroom Renovation Includes

A master bath at the high end of OCC’s range includes all of the following. Here is what the scope covers in full:

• Walk-in shower with custom tile surround, frameless glass enclosure, and built-in niches
• Freestanding soaking tub or drop-in tub with tiled deck
• Double vanity with undermount sinks, soft-close drawers, and brushed hardware
• Large-format porcelain tile on floors and walls — heated floor systems available
• PEX plumbing upgrade for the full bathroom including supply lines
• LED dimming fixtures, exhaust fan upgrade, and weatherproof outlet placement
• Custom built-in linen storage integrated with the vanity design

OCC manages every permit, every inspection, and every trade coordination from demolition through final walkthrough. Most master bath projects are completed in 2 to 3 weeks after permit issuance.

Room Additions and Second-Story Builds

When a home’s existing footprint is the constraint, a room addition solves the problem permanently. OCC builds four main addition types across St. Petersburg and Pinellas County.

Here is what each addition type involves and what it costs:

First-Floor Master Suite Addition

Adds a primary suite — bedroom plus full bath — to the home’s existing ground floor.

Estimated cost at OCC: $60,000 to $100,000

This scope includes foundation work, drainage planning, and roof integration. Here is what comes with a first-floor addition:

• New foundation poured and tied into the existing slab or footer
• Framing, insulation, and exterior finishes matched to the existing home
• Full master bathroom inside the addition — walk-in shower, double vanity, custom tile
• Walk-in closet with custom built-ins
• Electrical, plumbing, and HVAC extended into the new space
• Windows, siding, and trim matched to the existing exterior

Most first-floor master suite additions are complete in 8 to 12 weeks after permit issuance in Pinellas County.

Second-Story Addition

Adds a full second floor to a single-story St. Pete home. The most impactful way to double the home’s square footage.

Estimated cost at OCC: $200 to $250 per sq ft

This is the highest-complexity scope OCC builds. Here is what is required:

• Structural engineering assessment of the existing first-floor framing
• Reinforcement of load-bearing walls and foundation as needed
• Full second-floor framing, roof reconstruction, and exterior work
• Staircase design and installation integrated with the existing floor plan
• All systems — electrical, plumbing, HVAC — extended to the second floor
• Interior finishes, windows, and trim matched throughout

Second-story additions in St. Petersburg’s older neighborhoods often involve matching original rooflines and architectural details. OCC handles this coordination as part of the project, not as an add-on.

Garage Conversion

Turns an attached garage into a functional living space. One of the most cost-effective ways to add square footage.

Estimated cost at OCC: $80 to $120 per sq ft

Garage conversions work well for home offices, guest suites, in-law units, and playrooms. Here is what this scope covers:

• Insulation added to walls, ceiling, and garage door opening
• Electrical brought up to residential code and new circuits added
• HVAC extended into the converted space
• Flooring, drywall, and finishes matched to the rest of the home
• Exterior changes to match the home’s appearance with the garage door removed

A garage conversion under OCC’s rate is one of the most affordable ways to add a functional room in St. Petersburg.

What Drives Your Final Number?

Two luxury renovation quotes on similar homes can come back tens of thousands of dollars apart. These are the variables that move your number the most.

Project scope and combination

The single biggest factor is how many rooms are in the project. Keep the following in mind:

• Combining kitchen, bath, and addition under one permit saves mobilization and trade coordination costs
• A full multi-room renovation done together costs less in total than the same work done room by room. Running everything together under one licensed contractor is how St. Pete homeowners control costs on a major renovation.

Existing condition of the home

Older St. Pete homes often carry hidden conditions that affect cost. Here is what to plan for:

• Outdated plumbing — older copper or galvanized pipes that OCC replaces with PEX during renovation
• Original knob-and-tube electrical that requires upgrading to support modern circuits
• Slab-on-grade construction common in Clearwater and St. Pete — complicates drain relocation
• Aged rooflines and framing that require reinforcement before additions are built
• Florida Building Code wind-load requirements that govern every permitted addition

Addressing these conditions during the renovation rather than after is always cheaper. OCC plans for them upfront in every written estimate.

Material and finish tier

Material selection moves the number within OCC’s published ranges. Here is how the choices stack:

• Quartz and granite countertops outperform laminate in Florida’s humidity and at resale
• Porcelain tile lasts longer in Clearwater’s coastal environment than most flooring alternatives
• Frameless glass shower enclosures add cost over framed but are the most requested finish in the St. Pete market
• Custom cabinet builds cost more than semi-custom but hold up better in Florida’s year-round humidity

The right material tier for your home’s price point matters more than going as high as possible on every item.

Permits and Florida Building Code in Pinellas County 

A luxury renovation in St. Petersburg touches multiple permitted trades. Here is what requires a permit in Pinellas County:

• Any structural work — additions, wall removal, load-bearing changes
• All electrical work, including new circuits, panel upgrades, and fixture installations
• All plumbing work, including drain relocation, PEX upgrades, and fixture connections
• Mechanical work including HVAC extensions into new or renovated spaces
• Any attached structure, including sunrooms, covered patios, and screened enclosures

According to Pinellas County Building Services, all structural residential work in unincorporated Pinellas County requires a permit, engineered drawings, and inspection before the space is occupied. 

OCC handles the entire permit process on your behalf. Here is what that includes:

• Permit application filed directly with Pinellas County by OCC
• Engineered structural drawings submitted with the building permit
• All trade permits — electrical, plumbing, mechanical — pulled by OCC
• All inspections scheduled and managed without any homeowner coordination
• Full permit documentation handed to you at project close

Alex Richwagen, State-Certified Residential Contractor (FL License #CRC1334298), has managed permitted renovation and addition projects throughout St. Petersburg and Pinellas County since 2020.

Why Combine Scopes Under One Contractor?

The biggest advantage of a multi-scope luxury renovation is efficiency. Running everything under one licensed contractor and one permit package produces a better result at a lower total cost.

Here is what combining scopes under OCC delivers that separate projects cannot:

• One permit application covers all trades — electrical, plumbing, mechanical, structural
• One crew on site from start to finish — no scheduling gaps between separate contractors
• One written estimate covering the full scope with no gaps between trades
• Coordinated sequencing — plumbing rough-in before tile, electrical before drywall, additions before interior finishes
• One point of contact from permit application through final walkthrough

The alternative — running separate contractors on the kitchen, bath, and addition in sequence — creates scheduling gaps, coordination conflicts, and duplicate permit costs that add up quickly on a major project.
