Charleston Remodeling Permits in 2026: What Needs One, What It Costs, and How Long It Takes

Most of the kitchen and bath work people call us about inside the City of Charleston needs a permit, the fee is small next to the project, and the part that costs time is not the city but the drawings you hand it. This guide is the city's own rules on what needs a permit, what it costs, what to submit, and where the peninsula's flood zones and historic districts change the answer. Every figure is quoted from a city or state page linked at the bottom.

Is my address actually in the city?

Start here, because the city says so: “One of the first steps is to determine the appropriate jurisdiction for your project. Areas such as West Ashley, James Island, Johns Island, and Cainhoy include mix of properties that may or may not be incorporated within the City of Charleston.” The city's GIS map at gis.charleston-sc.gov shows city parcels shaded green; an address outside the shading is permitted by Charleston County's Building Inspection Services instead, under a different fee schedule and portal. Mount Pleasant, Isle of Palms and Sullivan's Island are separate towns with their own departments, covered in their own guides.

What needs a permit, and the short list that does not

The city's Benefits of Building Permits sheet gives the exemptions in one paragraph: “If the property is not in a BAR district or in Flood Zones AE and VE, then the following work is exempt from obtaining a building permit: Painting, papering, tiling, carpeting, and plug-in portable appliances. Kitchen and bathroom cabinets and counter tops are exempt only when no associated plumbing, fuel gas and/or electrical work is included.” Read the two conditions first. Move a sink, add an outlet, run a gas line to a new range, and the cabinet job is a permitted job. The city also lists what it calls express permits, which “have the possibility of receiving over-the-counter in-person approval” at the Permit Center: fences, paint, “in-kind window replacement, minor wood rot repair/siding replacement,” roofs, residential generators, interior non-structural demolition, residential solar, and standalone trade permits. Over the counter is not guaranteed; the city's word is “never.”

Two warnings on the same sheet are worth quoting because homeowners bear them, not contractors. “It is the property owner's responsibility to ensure building permits are obtained for building repairs and renovations prior to work commencing.” And “permits are not exempt following a natural disaster. All applicable permits must be obtained before repair work starts.” The fee schedule adds the penalty: where work is started before the permit, “the fees herein specified shall be doubled.”

Flood zones erase the exemptions

Inside the Special Flood Hazard Area the list above does not apply. The city states: “Building permits are required for all work on buildings in the Special Flood Hazard Area (SFHA), AE, and VE Flood Zones. This includes interior non-structural renovations and repairs of storm damage. Specifically, the replacement and repair of roofs, walls, siding, flooring, drywall, insulation, cabinets, ductwork, mechanical, electrical, plumbing, and gas systems requires a building permit.” The reason is the substantial-improvement rule: work that “equals or exceeds 50 percent of the building's assessed or appraised value” means “the building must meet the same construction requirements as a new building,” and since July 1, 2020 a residential substantial improvement must sit “1 ft. above BFE” while new construction sits at two feet. The permit is how the city counts toward that 50%, and the Substantial Improvement Package “must be submitted during permitting.” Our guide to the 50% rule covers how to find out where you stand before the design is finished.

Historic districts add a step before the permit

On the peninsula the building permit comes second. The zoning ordinance says that in the Old and Historic District no structure's exterior “visible from a public right-of-way” may be altered “until after an application for a permit has been submitted to and approved by the Board of Architectural Review,” and it defines the board's Certificate of Appropriateness as the approval “that entitles the applicant to apply for a building permit.” The residential application form itself asks “Has BAR approval already been granted?” Interior work is outside the board's reach; a new window opening or a rear addition that shows from the street is not. See our BAR approval guide for the board's calendar and what staff can sign off without a hearing.

What to submit for a remodel

The city's Single Family Alteration guidance, dated February 2026, sorts remodels into three tiers and lists the documents for each. With “no floor plan changes (interior or exterior)”: the building permit application, a BAR application if in a designated district, and “photos of existing conditions where work will take place.” With non-structural floor plan changes: the application plus “drawings showing existing, demo, proposed floor plans.” With structural changes: those drawings plus “stamped and signed engineering drawings showing structural changes,” and the city notes that an “engineer's letter specifying changes may be acceptable.” Electrical, gas, mechanical and plumbing sub-permits are pulled separately by each trade if in scope.

An addition is a different package. The Single Family Additions guidance requires “architectural & structural construction documents signed and sealed by licensed SC design professional” and “site plan showing the location of proposed addition with measurements,” with zoning and building review both required and BAR review where applicable. If the house is on Daniel Island, the city lists the “Daniel Island ARB” as a required non-city approval; our Daniel Island guide covers that board.

How to file, and the one rule that costs people weeks

Residential new construction, alterations and additions are submitted through the city's Customer Self Service portal, and “online permit submittals are processed in priority order before any submittals received via email.” The city accepts PDF only: “Any links, JPEG files, embedded documents, or other file types are not accepted.” The rule that catches people is this one: “City staff does not receive notifications when new documents get uploaded through CSS, please notify us at [email protected] to avoid processing delays if you upload supplemental documents through the portal.” A corrected drawing uploaded without that email can sit unseen. The Permit Center at 2 George Street, ground floor, keeps walk-in hours 9 a.m. to 4:30 p.m. Monday through Friday, closing at 2:45 p.m. on the fourth Wednesday of each month, and is reached at 843-577-5550. Once the permit is paid in the portal, its status updates to Issued “the midnight following payment,” and the placard is printed from the same account.

The city does not publish a plan-review turnaround for Building Inspections, and third-party review is available for inspections only, “approved by the Chief Building Official prior to commencement,” not for plans. So we do not promise a number for the city's review; we promise the submission will be complete on day one, which is the variable a contractor controls. Inspection scheduling is published: requests made before noon “will be scheduled one business day out,” after noon two.

What it costs

The Building and Trade Permit Fee Schedule in force is the one effective October 1, 2019, and it is still the current schedule in the copy the city printed in July 2025. Every building and trade permit starts with “a non-refundable permit application of $40.00.” For residential alterations, repairs and additions the fee is based on total construction cost, which the city defines as “all involved labor and materials, valued at the current retail market, plus overhead and profit (total contract price).” The table: $1,000 or less pays the application fee only; from $1,001 to $50,000, “$15.00 for the first $1,000 construction valuation, plus $5.00 for each additional thousand”; from $50,001 to $100,000, $260 for the first $50,000 plus $4 per additional thousand; from $100,001 to $500,000, $460 for the first $100,000 plus $3 per thousand; above $500,000, $1,660 plus $2 per thousand. Where drawings are reviewed, “the plan review fee shall be equal to one-half of the building permit fee,” and it covers the initial review plus one follow-up. Worked example: a $75,000 kitchen with a structural change pays $40 application, $360 permit, and $180 plan review, plus the trade permits, which run $3.50 per plumbing fixture, 25 cents per amp on a service upgrade, and $10 for the first $1,000 of mechanical work plus $2 per thousand after, each with its own $40 application fee. A plan revision after approval is $50 per trade discipline, and a failed inspection can carry a $100 re-inspection fee.

Who is allowed to pull it

South Carolina law defines a residential builder as anyone who constructs or superintends “the construction, repair, improvement, or reimprovement of a residential building or structure” of three floors or fewer “when the cost of the undertaking exceeds five thousand dollars,” and section 40-59-30 makes unlicensed practice a misdemeanour carrying a fine of $500 to $10,000 or thirty days, with a second consequence that matters more to you: an unlicensed person “may not file a mechanics' lien or bring an action at law or in equity to enforce the provisions of a contract.” The city's permit application asks for the “SC LLR License #” and the “City of CHS Business License #” on the form, and the city reminds owners that contractors need both. Check any licence number at the state's verification site, verify.llronline.com, before you sign. Ours is CLG.127339. On our jobs inside the city, the permit package is our work: the drawings, the engineer's seal where the scope needs one, the BAR or flood paperwork where the address needs it, the CSS filing, and the email that tells the Permit Center the file is complete.
