Why adus & in-law suites works the way it does in St. Augustine
About St. Augustine, FL. St. Augustine is the oldest continuously occupied European-founded settlement in the United States, set on Florida's northeast coast with a historic core dominated by colonial-era fabric, the Castillo de San Marcos, and a tightly preserved street grid. Surrounding the historic center are coastal residential neighborhoods, gated communities, and a steady second-home market drawn to the beach and historic character.
What it means for adus & in-law suites. St. Johns County and the City of St. Augustine both apply, and the Historic Architectural Review Board governs exterior work in the historic district under some of the strictest preservation rules in the state — material, fenestration, and roof-form decisions are reviewed in detail. Coastal parcels work under Florida Building Code with hurricane-exposure provisions, FEMA flood-zone elevations, and St. Johns County coastal construction rules. Typical work is sympathetic remodels of historic homes, custom coastal homes in surrounding gated communities, and boutique hospitality work near the historic core.

What We Do
One Property, Three Generations, Zero Compromise
Mother needs her independence; you need yours. Detached ADUs ($100K–$300K+) with their own kitchen, bath, and HVAC. Attached mother-in-law suites under $100K sharing utilities with the main home. Internal conversions for the in-between. Greenville County zoning, septic, and HOA review — we walk the lot before you fall in love with a plan that won't permit.
- Three classifications — detached, attached, or internal — chosen against your lot reality
- Designed to look like they were always there: matched trim, rooflines, finishes
- Greenville County code-compliant — adds resale value, not backyard sheds with electrical
- Permits, septic capacity, and zoning review handled before the first wall goes up

What Affects the Price
Every job is different. Here's what we look at when we put together your estimate — so there are no surprises on job day.
ADU type: detached structure, attached suite, or internal conversion
Square footage and number of bedrooms / baths
Septic system capacity and any utility extension required
Whether the ADU shares any walls or systems with the main home
Finish tier — standard, designer, or luxury (Shaw, Pelican, Armstrong)
Site access, grading, and any tree removal on the proposed footprint
We don't quote over the phone. Every estimate is done on-site because that's the only way to give you a number you can count on. No ballparks, no surprises.
Our Process
How We Approach
ADUs & In-Law Suites
Lot, Septic & Zoning Review
Greenville County zoning rules around detached ADUs are not the same as the city's, and septic capacity is the most common silent disqualifier. We walk the lot, pull current ordinances, and tell you up front what's possible — before you fall in love with a plan that won't permit.
Design It To Look Like It Was Always There
Trim profiles, rooflines, and material selections matched to your existing home. The goal is resale-positive, not 'backyard shed with electrical.' Three ADU classifications — detached, attached, or internal — chosen against your privacy, septic, and cost realities.
Permit, Build & Hand Over Two Front Doors
Full mechanical, plumbing, code-compliant egress. Detached ADUs get their own kitchen, bath, and HVAC. Mother needs her independence; you need yours. The result is a structure that adds resale value and gives every generation under your roof their own space.
Common Questions
ADUs & In-Law Suites FAQ
Answer
Three classifications. Detached ADUs share no walls with the main home — fully self-sustaining with their own kitchen, bath, and mechanical. Attached units share an external wall with the main home (often called mother-in-law suites). Internal ADUs convert existing home space into a self-contained living area.
