What to Know Before Building a Custom Home in Matthews, NC

Eric Brown 2026-09-23

Before you sketch a custom home Matthews NC buyers should treat the lot as a two-desk project. The Town of Matthews Planning & Development Department answers zoning questions, while Mecklenburg County's Land Use and Environmental Services Agency and Code Enforcement issue building permits and inspections.[1] Overlay districts, tree-canopy rules, and the Town's Post Construction Ordinance then shape the pad, the roof, and how much of the lot can be built upon. The work is to design a house that belongs on that street fifty years from now, not a production-subdivision product dropped onto an infill lot.

Two public desks, not one county counter

Matthews sits in Mecklenburg County, and the desks are split. Zoning, overlays, site-plan placement, landscaping, and land-use questions live with the Town. Structural building permits, trade permits, plan review against the North Carolina State Building Code, and inspections live with the County.

The Town Planning Director, working through the Planning and Development Department, administers the UDO: site plans, landscape plans, overlay compliance, sign permits, and zoning permits. Mecklenburg County LUESA and Code Enforcement, by interlocal agreement, receive grading and building permits, review plans, and inspect the work.[1] The Town's Unified Development Ordinance (UDO) is more direct still: when a structure is proposed, applicable building permits and inspections are obtained from Mecklenburg County Code Enforcement.[2]

Code Enforcement, a division of LUESA, issues building, electrical, plumbing, and mechanical permits as required by G.S. 160D-1110, reviews drawings for code compliance, and inspects the work in the field.[3][4] A new one- or two-family house typically goes through residential plan review (new construction, remodels, and additions for single-family, two-family, or townhomes three stories or fewer) before a permit is issued.[5] AccelaMeck is now the County's preferred portal for those projects, including demolition.[6]

G.S. 160D-1110 requires permits before construction, reconstruction, alteration, repair, movement, removal, or demolition of a building, with a limited exemption for work costing $40,000 or less that does not touch load-bearing structure, plumbing design, HVAC or electrical design, disallowed materials, or new roofing.[4] A ground-up custom house does not live in that exemption. Neither does a teardown.

Confirm the Town zoning envelope first (district, overlays, setbacks, canopy, stormwater). Then design a house that fits it. Then submit to the County for building-code review. Skipping the Town desk is how people discover, too late, that the house they drew cannot sit on the lot they bought.

Start with the UDO, the map, and Envision Matthews

Matthews regulates land use through a Unified Development Ordinance that combines zoning, subdivision, floodplain management, post-construction stormwater, and minimum housing standards. The Board of Commissioners adopted the current UDO on December 9, 2013. It went into effect April 1, 2014. The compiled ordinance text cited here is the Town's 2018 Full UDO document.[7]

Envision Matthews was adopted on May 13, 2024.[8] The Downtown Overlay exists to implement the Downtown Master Plan, which the UDO adopts by reference as a framework for downtown growth, conservation, and development.[13] If a lot needs a rezoning, staff already measure proposals against Envision Matthews in written reports.[8]

Do not guess the district. The UDO establishes district boundaries on the Official Zoning Map. The Planning Director maintains that map and provides printed or digital copies on request.[9] Those maps are reference tools, not field measurements. Confirm the lot against recorded deeds, plats, and the Town Planning Office.

Traditional single-family districts in the UDO include R-20, R-15, R-12, and R-9. The Table of Dimensional Standards sets, among other things, minimum lot area, minimum lot width, and minimum front and side yards. As reprinted in a May 2023 Board of Adjustment packet, R-20 starts at 20,000 square feet of lot area, 90 feet of lot width, and a 50-foot front setback. R-15 is 15,000 square feet, 80 feet, and 40 feet. R-12 is 12,000 square feet, 70 feet, and 35 feet. R-9 is 9,000 square feet, 60 feet, and 30 feet, with interior side yards listed at 8 feet and 6 feet.[10] Those numbers are not a design brief. They are the box the house has to live in. On an infill lot, that box is often the whole story: a 40-foot front yard on a 15,000-square-foot lot will not accept the same massing as a greenfield pad in a new subdivision.

If the house you want does not fit the current district, the Town's rezoning path is slow on purpose. A zoning map amendment requires a public hearing, a Planning Board recommendation, and a Board of Commissioners vote.[7] A vegetation survey, as described at UDO Section 155.606.8, is required at the time of zoning application on sites other than single-family residential.[11] A Post Construction Ordinance Concept Plan must be approved by the Storm Water Administrator before a rezoning application is approved, and a consultation on that plan is available at that early step.[15]

We would rather know that path before anyone falls in love with a floor plan.

Overlays, downtown, and Highway 51

Zoning in Matthews is not only a color on a map. Overlay districts sit on top of the underlying district and add a second set of physical standards for defined geographies. The UDO groups overlays separately from traditional and conditional-only districts. Overlay districts named in the ordinance include the Downtown Overlay (DO) and the Highway NC51 Overlay (HO). When overlay standards conflict with the underlying district, the ordinance text says which rule wins.[12]

The Downtown Overlay exists to implement the Downtown Master Plan. It covers the historic core and the fringe around it, and it is written around pedestrian scale, urban open space, and streetscape rather than a suburban setback pattern. Applicants planning any demolition, development, or redevelopment in the DO District must meet with Town Planning and the Development Technical Review Committee during conceptual design.[12][13] If you are looking at a teardown near Trade Street or John Street, that meeting is part of the process, not optional courtesy.

The Historic Urban Core (HUC) is a traditional district of its own. It is established for a defined downtown commercial core, including an existing designated Historic District, and it allows a mix of uses at greater lot coverage than outlying nonresidential districts while preserving small-town downtown character.[12]

The Highway NC51 Overlay protects scenic beauty along designated lengths of that thoroughfare, reduces unnecessary driveway cuts, and keeps buildings set back far enough that vehicles can stack before they enter the highway. It is mapped on both sides of the thoroughfare, generally 500 to 1,000 feet deep from the right-of-way.[12] If a parcel sits in both overlays, parcels fronting NC 51 follow the HO rules where the two conflict.[12]

A house that would be ordinary in a new production subdivision can be the wrong object on a Matthews street that still has a downtown, a railroad, and a highway overlay.

Infill and teardown lots: the envelope is the design problem

Many of the interesting lots in Matthews are not raw acreage. They are established neighborhood lots: a 1960s ranch on a tree-lined street, a small house on an R-12 parcel, a teardown candidate on a street that still has porches, side yards, and mature canopy. The process question is not whether a new house can be larger than the one that is there. It is whether a new house can sit inside the district's dimensional standards, keep enough canopy, drain correctly, and still belong next to houses built for a different era.

Start with the recorded plat, the zoning map, and a field measurement of setbacks. Front, side, and rear yards in the Table of Dimensional Standards are minimums, and corner lots and lots on thoroughfares pick up extra rules in other sections of Chapter 6.[10] A two-story house with a wide garage face can eat a 70-foot-wide R-12 lot before the living rooms even start.

Tree canopy is part of the envelope. The UDO's canopy table requires a minimum percentage of tree canopy to be maintained or created on a development site or any site of land-disturbing activity. In the 2018 compiled table, R-15 and R-20 are listed at 20 percent. R-9, R-12, and several related districts are listed at 15 percent. The purpose language is not ornamental. Canopy is treated as a measure of the site's ability to retard stormwater runoff, mitigate air pollution, and contribute to cooling.[14] On a teardown lot, that often means the specimen trees at the street and along the side lines are not "in the way of the house." They are part of what the Town is protecting, and they should be part of what the house is designed around.

Demolition itself is a County permit, as G.S. 160D-1110 and Mecklenburg Code Enforcement both treat removal or demolition as permitted work.[3][4] In the Downtown Overlay, demolition also triggers that conceptual meeting with Town Planning.[12] The sequence on an infill teardown is therefore: confirm the Town envelope and any overlay duties, inventory the trees, decide what can remain, pull the County demolition permit, then build inside the envelope you already proved.

We also renovate and add on. If the existing house still has a sound structure, a useful floor system, and a relationship to the street that a new house would only copy at greater cost, an addition or a whole-house renovation can be the more literate project. That is a separate conversation from whether the lot can take a new custom house. We are a building company, not only a new-home builder. The lot still has to be read the same way.

Stormwater is a Town ordinance, not a landscape afterthought

Matthews writes post-construction stormwater into the UDO as Chapter 8, officially the Post Construction Storm Water Ordinance and commonly the PCO. The stated purpose is to protect public health, safety, environment, and general welfare by setting minimum requirements for the adverse effects of increased post-construction runoff and non-point source pollution from new development and redevelopment.[15] Town storm-drainage design is required to conform to the PCO, the Charlotte Mecklenburg Storm Water Design Manual, the Mecklenburg County Land Development Standards Manual, or the more restrictive of any conflicting standards.[15]

North Carolina's Post-Construction Program, run in some places by DEQ and in others by local governments, exists for the same reason: to protect surface waters from stormwater after a project is built. DEQ's map is only a screening tool. In Matthews, the local PCO is the document that sits on the lot.[16]

That is why a PCO Concept Plan has to be approved before a rezoning application, and why a consultation on that plan belongs at the first site sketch, not after engineering is finished.[15] Roof area, driveways, patios, and walkways are built-upon area. On Piedmont clay they also become a drainage problem if they are aimed at a neighbor, a crawlspace, or a street inlet sized for a smaller house. Grading, downspout discharge, and any structural stormwater practice belong in the first site sketch, not after the slab is formed.

Piedmont clay under a Matthews house

The ground in this part of Mecklenburg County is Piedmont upland soil, not Coastal Plain sand. Two series are useful to know by name.

The Cecil series is the classic red Piedmont soil: very deep, well drained, formed in residuum from felsic igneous and high-grade metamorphic rocks, with a sandy loam surface over a firm, sticky, plastic red clay subsoil. Saturated hydraulic conductivity is moderately high. Shrink-swell potential is low.[17] The Mecklenburg series, first established in this county in 1910, is also very deep and well drained, but it formed from intermediate and mafic crystalline rocks. Saturated hydraulic conductivity is moderately low. Shrink-swell potential is moderate. The typical subsoil is yellowish red clay, firm, sticky, and plastic.[18]

"Well drained" in a soil series description is not the same as "easy to build on." NC State Extension is blunt about new house sites in the Piedmont. Much of the subsoil has high clay content. Construction removes topsoil, places compacted subsoil around the foundation, and further slows water movement. Clay soils tend to remain wet for long periods. Compaction restricts root growth and reduces infiltration. Extension's advice for the finished yard is organic amendment and tillage rather than a light dusting of sand, which can produce a concrete-like mix if it is not added in very large volume.[19]

Have the soils identified for the specific parcel. The USDA Web Soil Survey is the public starting point, not a substitute for a geotechnical report on a difficult lot.[20] Grade the pad so water falls away from the foundation. Size footings and drainage for clay that holds water and, in the Mecklenburg series, has moderate shrink-swell. The same clay that makes a handsome red cut bank will puddle in a compacted side yard after a summer storm.

Covenants sit on top of the Town and the County

Public zoning is not the last word on many Matthews lots. If the parcel is in a planned community, a recorded declaration of covenants can govern massing, materials, fences, tree removal, and architectural review even when the Town would allow the house.

North Carolina's Planned Community Act, Chapter 47F, applies to planned communities created in the state on or after January 1, 1999, with exceptions for communities of no more than 20 lots and for wholly nonresidential communities unless the declaration opts in. Some provisions also apply to older communities unless the articles or declaration say otherwise.[21] Unless those documents provide otherwise, an owners' association may adopt rules and, after notice and an opportunity to be heard, impose reasonable fines for violations of the declaration, bylaws, and rules.[22] That is the statutory skeleton. The architectural standards themselves live in the recorded documents. Read them before you buy, and again before you draw. An association that requires a brick front, a particular roof pitch, or review of a teardown is not overriding the UDO. It is adding a private layer the house still has to satisfy.

We treat that layer as part of the same process as Town zoning. A house that is legal at the Town counter and rejected by an architectural committee is not a finished design.

A Matthews house should still read as a home

Matthews is not a blank subdivision. Envision Matthews is the Town's adopted 2024 plan, and the Downtown Master Plan, adopted by reference in the UDO, is explicit about the historic core, the fringe around it, and pedestrian-scale infill.[8][13] Scale the mass to the lot and to the neighboring roofs. Put the garage where it does not dominate the street. Keep the trees that make the street worth living on. Use materials that will still look considered in twenty years, not a catalog elevation that could sit anywhere along I-485.

Every ground-up house we build is individually designed. We can collaborate with an architect you have already selected, or we can connect you with experienced local architects. The lot, the overlay, the soils, and the way your family lives belong in that first conversation. Eric Brown is on site. We have been a family-owned building company in the South Charlotte metro since 2006, deliberately small, and we still take on renovations and additions when the existing house is the right starting point.

What we build today should still make sense fifty years from now. That is harder on a Matthews infill lot than it looks from the street, which is why the process comes first.

Practical takeaways

Pull the Town zoning map and the recorded plat before you sketch. Confirm the district, any overlay (Downtown, Highway 51, or others), and the actual setbacks on the ground.[9][10][12]
Treat Matthews Planning and Mecklenburg County Code Enforcement as two desks. Zoning and the UDO are Town. Building permits, plan review, demolition, and inspections are County, through AccelaMeck for most residential work.[1][3][6]
Budget time if the lot needs a rezoning. A vegetation survey on sites other than single-family residential, and a PCO Concept Plan, sit in the path before a map amendment is approved.[11][15]
Inventory trees early. Canopy percentages in the UDO are district-based (20 percent in R-15 and R-20, 15 percent in R-9 and R-12 in the 2018 compiled table) and they affect where the house can sit.[14]
Design drainage with Piedmont clay in mind. Cecil and Mecklenburg series soils have clay subsoils; construction compaction makes them slower. Grade away from the foundation and do not leave stormwater as a landscape leftover.[17][18][19]
Read the HOA declaration as a third layer, not a courtesy. Chapter 47F supplies association powers and hearing rules. The architectural standards are in the recorded covenants.[21][22]
If the existing house still works, ask whether an addition or renovation is the more lasting project. A teardown is a process, not a default.

How we can help

If you have a lot in Matthews, or a house you are deciding whether to keep, we will walk the property with the UDO, the soils, and the street in mind, then tell you honestly what the envelope will support. Schedule a consultation and tell us about the lot. We listen, we design individually, and we stay on site through the work.
