Fort Bend and Montgomery counties are outpacing Harris in new households. Permit data and USPS delivery counts show exactly where people are landing — and where schools and roads are already falling behind.
The conventional wisdom about Houston’s growth corridors is about three years out of date. If you’ve been relying on American Community Survey rankings — the ones most regional outlets keep recycling — you’re reading history.
Fort Bend County issued roughly 13,500 residential building permits in 2024. Montgomery County issued around 16,000 — both figures from county engineering departments, both among the highest per-capita rates in Texas. More telling are U.S. Postal Service delivery statistics: quarterly counts of active residential delivery points by ZIP code, which confirm that permitted homes are actually occupied by people receiving mail.
ZIP codes 77441 (Fulshear), 77354 and 77356 (Magnolia and the Lake Conroe area), and the 77433/77377 corridors covering Cypress and Tomball are posting the strongest delivery-point increases in the metro. These are not projections. They are addresses where someone is getting mail.
The post-2022 migration wave has shifted where Houston’s new households are landing. This piece is built on permit totals and USPS counts, not ACS estimates that lag by two to three years.
How We Measured This
Building permit totals come from county engineering departments and the Home Builders Association of Greater Houston, which tracks permit issuance by jurisdiction monthly. USPS Delivery Statistics — available through the USPS Business Customer Gateway — record active residential delivery points by ZIP code each quarter.
The distinction between the two matters. Permits are issued before a home is built or occupied. USPS counts confirm someone moved in. A developer can pull 500 permits; if the USPS count doesn’t move, those homes are sitting vacant or construction has stalled.
The ACS has a two-to-three-year publication lag. It cannot tell you what happened last fall. The USPS data can. That’s the difference between reporting on growth and reporting on where growth used to be.
Fulshear: From Crossroads to 40,000 Residents
Fulshear is the clearest growth story in the Houston metro right now. In 2010, the city had roughly 1,300 residents. By 2025, the estimate is around 38,000. That’s a thirtyfold increase in 15 years, and it still catches me off guard every time I look at it.
Three things made it happen. Grand Parkway (TX-99) access to the Energy Corridor. Proximity to the Texas Medical Center. And a land base large enough that master-planned communities can still operate at real scale.
Cross Creek Ranch and Fulshear Lakes are the two dominant MPCs currently delivering lots. D.R. Horton, Perry Homes, and Toll Brothers are all active on the ground. Entry-level production homes in Fulshear are running around $340,000 — below the Harris County premium, competitive with northern Montgomery County, and with a materially shorter drive to the Energy Corridor and Medical Center than buyers get by going north.
The remaining developable land in Fulshear’s ETJ is substantial, but the easiest lots — the ones with MUD infrastructure already in and Grand Parkway frontage already resolved — are being absorbed. The city is not close to buildout, but the window on the simplest land is narrowing.
Fort Bend’s overall permit total for 2024 ranked near the top of the metro’s county-level figures. Fulshear’s share of that reflects what happens when road infrastructure precedes growth rather than chases it. The Grand Parkway segments serving this corridor were largely complete when the growth arrived. That sequencing is rarer than it should be in suburban Texas, and it’s the single biggest reason Fulshear has outperformed expectations.
Montgomery County Is the Metro’s Highest-Volume Permit Jurisdiction, With Three Distinct Growth Zones
Montgomery County is not one market. It’s at least three, with different price points, buyer profiles, and infrastructure problems. Treating it as a single data point produces a wildly misleading picture.
Conroe is the county seat and the most established of the three. Population is approaching 115,000, anchored in part by Woodforest, a master-planned community that has ranked among the top-selling MPCs in the country for several years running. Conroe is increasingly a city with urban-scale service demands — more complex than a bedroom suburb, which matters when you’re evaluating school and infrastructure capacity.
The FM 1488 corridor west of Conroe — Magnolia and surroundings — is the county’s fastest-growing and most price-sensitive zone. Entry-level new construction along FM 1488 runs around $310,000, which is meaningfully below Fulshear and well below Cypress. Magnolia is absorbing buyers priced out of The Woodlands, whose resale median now sits above $500,000, and remote workers who want square footage and lot size over a short commute. Builder activity here is dense.
The honest version of the FM 1488 story: the appeal is almost entirely about price. Buyers here are making an explicit trade-off between affordability and drive time, and the road situation — more on that below — makes that trade-off considerably more concrete than it looks on a listing sheet.
Willis and the Lake Conroe tier (ZIP 77356 and surrounding areas) attract a third distinct buyer: retirees and remote workers who want lake adjacency, lower prices than The Woodlands, and waterfront-adjacent amenity. This isn’t a high-volume permit market. But the remote-work migration that accelerated after 2020 gave it staying power it never had when it was primarily a second-home and seasonal market.
The structural driver for the entire northern Montgomery County tier is The Woodlands, which is functionally land-constrained and price-premiumed enough to redirect demand north and west. That dynamic has been consistent for years. It’s not reversing.
Harris County’s Remaining Growth Is Second-Phase Infill, Not Greenfield
Harris County is the most land-constrained of the three primary growth counties, and its permit activity reflects it. Growth is concentrated in two corridors: Bridgeland and the broader Cypress area along Hwy 290, and Tomball/Klein along Hwy 249.
Bridgeland, developed by Howard Hughes Corporation, is targeting roughly 11,000 homes at buildout. It’s well-capitalized and professionally managed, with amenities that compete with anything in the metro. It draws buyers from the Energy Corridor and northwest Houston’s industrial employment base. Entry-level new construction in the Cypress corridor runs around $380,000 — reflecting closer-in location and tighter lot supply relative to Fort Bend or northern Montgomery County.
The critical point is that Harris County’s growth is increasingly second-phase infill within established MPCs rather than greenfield development on new land. Permit volumes in Harris County unincorporated zones are running behind both Fort Bend and Montgomery. That gap is structural, not a down-cycle.
Harris County also carries a constraint the other two counties don’t: flood exposure at scale. The Harris County Flood Control District’s buyout programs are actively limiting where new permits are issued in lower-lying areas. Post-Harvey buyer psychology continues to shape where households choose to locate, and I don’t expect that to change — not with another active hurricane season behind us. Newer Fort Bend and Montgomery County developments built to post-2017 drainage standards on higher ground carry a real marketing advantage on flood exposure relative to older Harris County subdivisions. Buyers from outside Texas notice this immediately. Even some longtime Houston residents do now.
What Is Driving Growth in These Submarkets
Fort Bend’s growth is job-proximity growth. The Energy Corridor hosts major energy employers within commuting distance of Fulshear via the Grand Parkway. The Texas Medical Center is accessible. These are concrete job anchors — not lifestyle marketing, actual employment destinations — and they explain Fort Bend’s household formation numbers.
Montgomery County’s growth is a different mix: remote-work migration, The Woodlands employment cluster, and price arbitrage working together. ExxonMobil’s campus in The Woodlands employs thousands. HP’s corporate campus is there. But a growing share of northern Montgomery County’s new households work remotely or on hybrid schedules that make a drive to The Woodlands manageable two or three days a week. At $310,000 in Magnolia versus $500,000-plus in The Woodlands resale, the math is obvious.
The Houston metro’s affordability advantage over peer Texas markets is still underappreciated by people relocating from elsewhere. The metro new-home median runs around $350,000 — well below Austin (above $480,000) and the major DFW growth corridors (above $430,000). That gap is real and it’s driving migration decisions.
One current market mechanic worth understanding: builders across all three counties are competing on mortgage rate buydown incentives rather than list price cuts. 2/1 buydowns are standard in active MPC phases. The list price is less negotiable than the financing structure. Buyers who focus negotiation on rate buydowns are operating on correct market intelligence. Buyers who don’t know to ask about it are leaving money on the table.
Schools Are Running Two to Four Years Behind Rooftop Delivery
Every fast-growth suburb in the Houston metro faces a lag between when homes are occupied and when school capacity catches up. The pattern is predictable — and yet it still surprises buyers who didn’t ask about it before closing.
Conroe ISD passed a $1.1 billion bond in 2023 — one of the largest in its history — to fund new campuses and expansions across its growth zones. The district is still running some campuses at or near capacity in the fastest-growing sectors. Bond-funded relief requires new buildings to open before it delivers. Conroe ISD serves both the Woodforest market and portions of the northern expansion zones; enrollment projections built into the bond program anticipate continued household formation at current pace through the late 2020s.
Lamar Consolidated ISD is opening new schools in the Fulshear and Richmond corridor as Fort Bend’s growth continues. Assignment boundaries in fast-growth districts change frequently enough that information from 12 months ago may already be wrong. Don’t rely on what the builder’s sales agent told you at the model home. Check directly with the district before you close.
Magnolia ISD is absorbing Montgomery County’s western growth with a smaller financial base than Conroe ISD. Capacity constraints are a documented concern among residents in the area. In any fast-growth Texas suburb, the school situation two years from move-in will look different from the school situation at close. Treat school capacity as a variable, not a fixed feature.
Infrastructure: The Chokepoints That Will Determine Where Growth Goes Next
Roads and drainage aren’t abstractions in suburban Houston. In several of these markets they’re the actual growth ceiling.
The I-45 North widening project is one of the most consequential and most delayed infrastructure decisions in the metro. It would address the corridor connecting downtown Houston through Spring, The Woodlands, Conroe, and Willis. It has been politically contested and is years behind any schedule that would deliver meaningful capacity relief. For Willis and northern Conroe, the southbound I-45 commute during peak hours is a genuine quality-of-life constraint that limits how hard builders can push prices. Until I-45 North moves, the northern Lake Conroe tier retains a ceiling on its appeal to commuter households. That’s not speculation — it’s what you hear from anyone who’s driven that stretch on a weekday afternoon.
FM 1488 between Magnolia and Conroe is one of the most congested two-lane roads in the Houston suburbs. A widening project is underway but incomplete as of early 2026. Heavy residential growth without proportional road capacity is the daily lived experience for Magnolia residents right now. Builders and agents in the corridor acknowledge it openly. The widening, when complete, will likely unlock a further round of MPC development in western Montgomery County.
Fort Bend’s infrastructure story is the positive contrast. The Grand Parkway Segments H and I opened Fulshear to large-scale development by providing direct connectivity to the Energy Corridor and the broader metro freeway network before the growth fully arrived. This is what working infrastructure looks like in practice, and it’s the core reason Fulshear’s trajectory looks different from what’s happening north of The Woodlands.
On MUDs: Municipal Utility Districts are the financial engine of Texas suburban development and the leading indicator of where growth is already pre-approved and infrastructure-financed. When a developer creates a MUD, it establishes a special district with authority to issue tax-exempt bonds funding water, sewer, and drainage infrastructure — bonds repaid by property tax levies on homes built within the MUD. If you’re buying in an active MUD, you will see a MUD tax rate on top of your county and ISD rates. Calculate that line item before you fall in love with a list price. Active MUD bond issuance in a given ZIP code reliably signals that permitted growth is already capitalized and will convert to occupied homes. Both Fort Bend and Montgomery counties are currently showing active MUD bond activity in their primary growth corridors.
Harris County’s drainage situation deserves specific mention. The HCFCD buyout program has removed thousands of flood-prone properties from the housing stock since Harvey, and ongoing buyout activity in certain ZIP codes is both reducing available supply and signaling flood risk that redirects new buyer demand to Fort Bend and Montgomery. If you’re weighing older Harris County subdivisions against newer construction elsewhere, our coverage of which Houston neighborhoods have improved their flood risk after Harvey’s drainage projects lays out exactly where conditions have changed. This isn’t a temporary condition.
Katy, Sugar Land, and The Woodlands Are Not Growth Stories Right Now
National ranking sites that cite Katy, Sugar Land, or The Woodlands as top Houston growth markets are using data that reflects where growth happened. There’s a difference, and it affects every decision downstream of that misread.
Established Katy — ZIP codes 77494 and 77450 — is showing rising resale inventory and slower absorption in some MPC phases. It’s a functional market with strong schools and established commercial infrastructure. But buyers in Katy are increasingly competing with resale inventory from homeowners who purchased during the 2020–2022 appreciation run and are now testing the market. That’s a resale dynamic, not a growth story.
Sugar Land and Missouri City’s flagship MPCs — Sienna and Riverstone — are approaching buildout. There’s limited raw land for new MPC phases at the scale that characterized those communities a decade ago. It’s a healthy resale market. It’s not moving USPS delivery counts.
The Woodlands priced out a significant share of buyers it once captured. That demand has gone north and west — and The Woodlands has become the reference point that makes Magnolia and Willis look affordable by comparison. Five years ago that sentence would have seemed strange to write.
Pearland is the cautionary parallel. It was one of the fastest-growing suburbs in the Houston metro through most of the 2010s. It’s now showing the absorption slowdown that characterizes a market that has delivered most of its available land while adjacent markets offer comparable product at competitive prices with newer infrastructure. “Fast-growing suburb” is a temporary designation. Pearland is the reminder.
What to Watch for the Rest of 2026
Q1 and Q2 USPS delivery counts in ZIP codes 77441 (Fulshear) and 77354 (Magnolia) will confirm whether the recent growth pace is holding or beginning to moderate. These numbers release quarterly and are publicly accessible. Sustained delivery-point increases confirm household formation is keeping up with permit issuance. A plateau signals absorption softening before it shows up in builder cancellation rates or permit filings — which makes it genuinely useful early data, not lagging confirmation.
Montgomery County permit totals through the spring building season (March through June) are the leading indicator for the county’s full-year 2026 performance. Spring is when production builders pull the bulk of their permits. A decline from 2024–2025 pace would signal either demand softening or land supply constraints beginning to bite in the most active corridors.
Conroe ISD and Lamar CISD enrollment figures in August 2026 will be the most honest available measure of whether school infrastructure is closing the gap with home delivery or falling further behind. Both districts publish enrollment by campus. Comparing August 2026 figures against stated campus capacities will tell you whether bond-funded construction is actually keeping pace.
TxDOT milestones on I-45 North are worth monitoring. Any movement on right-of-way acquisition or construction letting in the Conroe/Willis segment would materially change the growth calculus for northern Montgomery County’s commuter buyer pool. The absence of milestones by mid-2026 would confirm the infrastructure constraint on that corridor runs through at least the end of the decade. I’m not holding my breath — but movement there would be a genuine game-changer for the Lake Conroe tier.
Flood and hurricane season buyer psychology will keep advantaging newer Fort Bend and Montgomery County development over older Harris County subdivisions. Post-Harvey buyer behavior has proven durable. Newer MPC developments built to post-2017 drainage standards on higher ground have a concrete advantage over older subdivisions that took water in 2017. That advantage compounds every active hurricane season. Buyers weighing this alongside broader homeownership costs should also review what Houston homestead and other property tax exemptions homeowners often miss — the MUD tax rate is one line item, but it rarely operates alone.
For readers actively choosing between these submarkets — and this falls squarely within our moving and real estate coverage — the data points to Fulshear and the Magnolia corridor as the places where the most new households are forming, where builders are competing hardest on financing, and where land supply still supports genuine new-construction choice.
Cypress and Bridgeland make sense for buyers who want closer-in Harris County location and will pay for it. Conroe and Woodforest work for buyers who want established MPC amenity and school infrastructure with the budget to compete at that price tier.
The Woodlands, Katy, and Sugar Land are resale markets now. The growth is north and west. The data confirms it.
