Building or buying new? Let’s make sure the builder’s contract works for you — not just for them.
Schedule a New Construction ConsultationMost builders I meet do not think they need a real estate agent. They can sell their own houses, they bring their own buyers, and they are not wrong about either one.
The catch is that they need dirt. And finding a Raleigh lot that will actually carry the house you want to put on it is a different skill from selling the house once it is up. That is the work I do, and it is the reason my team sits inside the Jim Allen Group.
This is the order I check a lot in. It is Raleigh-specific on purpose — see the note at the bottom about the rest of the Triangle.
The 30-second version
- The overlay kills more deals than the district does. A Neighborhood Conservation Overlay supersedes the base zoning, and Raleigh has 21 of them — including North Hills, North Ridge South and North Ridge West.
- Lot width is the number that decides it. Not acreage. A wide-but-shallow lot and a narrow-but-deep lot of identical size build completely differently.
- Conventional and Compact development are different rulebooks in the same district. Quoting the wrong one is the most common mistake I see.
- An overlay can impose a MAXIMUM lot size, which is what stops lot assembly cold in the neighborhoods where assembly would otherwise pay.
- Verify every number before you write the offer. The UDO is amended by text change; the figures on this page are dated and linked, not permanent.
Step one: the base district, and which rulebook applies
The base zoning district sets the floor for what the lot can carry. In Raleigh's residential districts that means a minimum lot area, a minimum width, a minimum depth, and the setbacks that decide where the house can actually sit.
Here is the part builders get wrong: the same district has two different sets of numbers depending on the development option. Conventional development and Compact development are separate standards, and a lot that fails one may pass the other.
For a detached house under conventional development, as published in UDO Sec. 2.2.1 and current as of August 2026:
| District | Min lot area | Min width | Min depth | Front | Side | Rear |
|---|---|---|---|---|---|---|
| R-4 | 10,000 sf | 65' | 100' | 20' | 10' | 30' |
| R-6 | 6,000 sf | 50' | 80' | 10' | 5' | 20' |
Height caps at 40 feet or three stories in both. Compact development runs lower minimums — R-4 drops to 7,500 square feet — which occasionally rescues a lot that fails conventional. Know which one you are pricing before you make an offer, because the difference is a whole building envelope.
Those figures were accurate when this page was written. The UDO is amended by text change; confirm the current standard on the section linked above before you rely on it.
Step two: the overlay, which is what actually kills deals
This is the step that separates people who have done Raleigh infill from people who have read about it.
A Neighborhood Conservation Overlay District supersedes the underlying district's requirements inside its boundary. Your parcel can be zoned R-4, and the R-4 table above can be completely irrelevant to what you are allowed to build.
Per UDO Sec. 5.4.3, an NCOD can set its own minimum and maximum lot size, maximum residential density, lot width, front, side and rear setbacks, building height, driveway and vehicular surface standards, building placement, entrance location, and distance between structures.
Read that list again and note maximum lot size. That is the provision that stops lot assembly — the play where you buy two adjacent parcels to unlock frontage or a bigger footprint. In an NCOD with a maximum, assembling can put you out of compliance rather than ahead.
Raleigh's 21 NCOD neighborhoods
As adopted and listed in Sec. 5.4.3: Brookhaven, Forest Park, Five Points East, Foxcroft, Glen Forest, King Charles, Laurel Hills, Mordecai, New Bern-Edenton, North Boylan, North Hills, North Ridge South, North Ridge West, Oakwood Park, Oberlin Village, Roylene Acres, Runnymede Road, South Park, Trailwood, West Idlewild and Willow Run South.
Two of the names on that list — North Hills and North Ridge — are exactly where the North Raleigh teardown money wants to go. Both carry overlays. If you are pricing a lot in either and you have only read the base district, you have not priced the lot.
Separately, Raleigh maintains eight Historic Overlay Districts: Blount Street, Boylan Heights, Capitol Square, Glenwood-Brooklyn, Moore Square, Oakwood, Oberlin Village and Prince Hall. These govern exterior changes and design rather than lot geometry, and a Streetside HOD only regulates what is visible from the street. Different instrument, same lesson — find out before you own the dirt.
Step three: lot width, not lot size
Acreage is the number everyone quotes and it is rarely the number that decides the deal.
Two 10,000-square-foot lots build completely differently if one is 65 feet wide and the other is 100. Width interacts with the side setbacks to produce the only measurement that matters: how wide the house can actually be.
On an R-4 lot with 10-foot side setbacks, a 65-foot-wide parcel leaves 45 feet of buildable width. A 75-foot parcel leaves 55. That ten feet of lot is the difference between a plan that needs a side-entry garage and one that does not — and on a spec build it can be the difference between a floor plan that sells and one that sits.
Depth does similar work at the back of the lot, where a 30-foot rear setback in R-4 eats into the pool and outdoor living space luxury buyers now expect.

Schedule a New Construction ConsultationStep four: the buildable envelope
Once you have the district, the overlay and the dimensions, the envelope is arithmetic. Lot width minus both side setbacks. Lot depth minus front and rear setbacks. What is left is the footprint you get to work inside, before you account for height limits, lot coverage and impervious surface caps.
I run this before a client falls in love with a parcel, because the envelope decides the plan and the plan decides the sale price. See designing a home for an infill lot for what happens after the envelope is known, and impervious surface limits for the cap that catches people with driveways and pools.
Step five: can it be split?
The highest-return infill play in Raleigh is not always one house. It is one parcel that legally becomes two.
Splittability turns on whether each resulting lot independently meets the district minimums — area, width and depth — plus street frontage and access, plus whatever the overlay says. A 20,000-square-foot R-4 parcel looks like two 10,000-square-foot lots until you measure the width and find that only one of them clears 65 feet.
This is where the money is, and it is also where the wishful thinking is. The parcel either splits or it does not, and the answer is in the dimensions before it is in anyone's pro forma.
Step six: the physical checks the ordinance does not cover
Zoning tells you what is permitted. It does not tell you what is possible.
- Topography. Slope decides foundation type and grading cost, and a steep lot can add tens of thousands before a wall goes up. I read topo before I get excited about a location.
- Utilities at the street. Water and sewer at the frontage, or a connection cost that changes the deal.
- Legal access. Frontage on a public street, or a recorded easement you have actually read.
- Soils. Dirt that will hold what you intend to put on it.
- Trees. Protected specimens and tree conservation requirements can redraw an envelope that zoning allowed.
More on all five in how I find infill lots and what to check before buying land.

Schedule a New Construction ConsultationWhy builders end up calling me anyway
You do not need me to list the finished house. You might need me to find the lot that makes the house worth building — and to tell you, before you are under contract, that the parcel you are excited about sits in an overlay with a maximum lot size and a 5-foot difference in setback that costs you the plan.
That is the work. Off-market flow, ownership tenure, the tired ranch on the oversized lot that has not turned over in forty years, and the dimensional read that tells you whether it pencils. If you build in Raleigh and you are hunting dirt, let's talk.
A note on the rest of the Triangle
Everything above is Raleigh. Every municipality writes its own ordinance — Durham, Cary, Chapel Hill, Apex, Wake Forest and the rest each run their own, with their own districts, their own numbers and their own overlays. The method on this page transfers anywhere. The numbers transfer nowhere.
If you are working a lot outside Raleigh, ask me and I will read that jurisdiction with you rather than guess from this one.
