Disclosure: This guide is written by a Texas custom home builder. We have a perspective on the build vs. buy decision and on which builders deliver on time. We've tried to give you the honest picture, including options like manufactured homes and DIY builds that wouldn't put a dollar in our pocket.
-----
Quick answer: Building a house takes 7 to 12 months on average. The U.S. Census Bureau reports an average of 7.7 months of construction time from start to completion, plus about 1.4 months for permitting. In Texas, most custom homes take 9 to 14 months from contract signing to move-in.
Here's the fast version:
We've been building custom and semi-custom homes in Montgomery County, around Lake Conroe, and throughout the Houston area since 1999. This guide walks through the real timeline based on what we see on our jobsites, including the Texas-specific variables (clay soil, hurricane season, county permitting) that most national guides miss.
The answer depends on what you're counting. Three different numbers get quoted:
ScopeTimeSourceConstruction only (nationwide)7.7 monthsU.S. Census Bureau, 2024Permit + construction~9.1 monthsU.S. Census Bureau, 2024Contract signing to move-in (custom)10 to 14 monthsIndustry standard
Custom homes usually add another two to four months on top of the construction window for design, selections, and financing.
There's also real regional variation. The Northeast had the longest duration from permit to start at 60 days, while the Midwest had the shortest average duration at 27 days. Texas sits in the middle, though Montgomery and Fort Bend Counties have seen longer waits as both regions absorb heavy population growth.
A production home built from a plan the builder has used 500 times has almost nothing in common with a fully custom home designed from scratch. If you're building custom and looking at a 7-month national average, you'll be disappointed.
Here's how timelines actually break down:
Builder typeContract to keysWhyProduction builder (Lennar, Pulte, etc.)4 to 7 monthsExisting plans, bulk purchasing, dedicated crewsSemi-custom builder (our approach)7 to 10 monthsProven plans with modificationsFully custom builder12 to 18+ monthsDesigned from a blank slateOwner-builder~14 monthsMost delays come from inexperience, not construction
According to LevelSet, owner-built homes take an average of about 14 months to complete. That's roughly twice a professional build. The further you move toward fully custom, the more decisions you're making. More decisions means more opportunities for delay.
"We couldn't be happier with Dunn & Stone Builders! Our home in Magnolia was completed in July 2017. This is our second Dunn & Stone home. After researching several new home builders, it became evident that no one else could match the quality and competitive cost to build our home." — Karen K., repeat Dunn & Stone client (see more reviews)
Texas adds three variables that don't show up in a national average.
Most of the greater Houston area sits on expansive clay that swells with moisture and shrinks when it dries out. Homes here almost always need engineered post-tension slab foundations, which are reinforced concrete slabs with steel cables tensioned after the pour to resist soil movement. This adds a week or two of site prep compared to simpler foundations in drier regions.
We've seen builds where skipping soil testing led to foundation failures that cost $30,000 to $80,000 to fix five years in. The extra week up front is non-negotiable.
From June through November, we plan for at least one significant weather pause. Heavy rain shuts down foundation work until the lot drains. Hurricanes and tropical storms can pause jobs for one to three weeks if materials are damaged or power is out across a crew's service area. Summer heat above 100°F slows concrete cures and pushes outdoor trades to early-morning-only work.
Across a full Texas build, we typically lose two to four weeks to weather. We build that into the schedule up front instead of pretending it won't happen.
In our service area, permit timelines are anything but uniform. Here's what we're seeing in the permit offices as of Q1 2026:
JurisdictionTypical residential permit waitMontgomery County (unincorporated)2 to 4 weeksCity of Conroe3 to 6 weeksCity of Montgomery2 to 4 weeksThe Woodlands / Montgomery MUDs4 to 8 weeksHarris County6 to 10 weeksFort Bend County4 to 8 weeks
A few Texas-specific wrinkles worth knowing:
Realistic Texas custom home timeline: 9 to 14 months from contract signing to keys.
Here's what a typical 2,500 to 3,500 sq ft custom home looks like on our schedule. Actual projects vary, but this is close to the median build we run. You can see completed examples in our portfolio.

A 3,500 sq ft custom home in Conroe, signed in January with no major delays, realistically hands over keys in October or November of the same year.
Square footage is the single strongest predictor of build time.

These are construction-only estimates, not counting preconstruction and permitting.
Finishes. Cabinet installation, trim work, flooring, tile, paint, and exterior cladding account for about a third of the total build.
Across a typical 10-month build, the time share looks like this:
Combine preconstruction and finishes, and more than half the total project time sits in the two phases where decisions matter most. This is why builders who rush preconstruction almost always run long at the end.
The number one killer of timelines is decisions made slowly or changed mid-build. According to New York homebuilder Peter Di Natale, change orders will usually extend the build time, especially if they occur in the latter part of the process. Every change touches multiple trades, materials, and schedules.
Lock selections before breaking ground. Resist the urge to "tweak" once framing starts.
We budget for two to four weeks of weather delays across a full Texas build. Hurricane season, spring storms, and triple-digit heat all slow outdoor work. Concrete is the most weather-sensitive. Fresh concrete needs days to cure, and heavy rain on day two can ruin a pour.
On one 2022 build near Lake Conroe we lost three weeks to back-to-back September storms. We were lucky we hadn't framed yet.
Permitting timelines vary by municipality and are often outside your builder's control. Submitting clean plans the first time is the fastest path through. The Montgomery County Permit Office has been explicit that incomplete submittals will be rejected. A single missing field sends you back to the bottom of the pile.
The construction industry has long faced a shortage of skilled tradespeople. Homebuilders work with people who have special skill sets necessary to build homes, like plumbers, electricians and tile setters. In Houston, the best trade crews are booked three to six months out. Builders with long-standing relationships get priority. Newer builders and owner-builders wait.
Special-order windows, custom cabinets, imported tile, and high-end appliances can have lead times of 8 to 16 weeks. If the order isn't placed early enough, installation gets pushed. This is the other reason (beyond change orders) that cabinet delays are so common.
Buried debris, unmarked utilities, rock, high water tables, or engineering surprises all add time. A thorough pre-purchase site survey catches most of these, but not all. Lots backing up to creeks or bayous are especially prone.
If you're using a construction loan, delays in draw approvals, appraisals, or inspections can stall the job. Builders can't pay subs if the bank hasn't released the draw, and subs don't show up if they haven't been paid. A one-time close construction-to-perm loan (like the one-time close loans we help our buyers set up) eliminates a lot of this friction.
Owner-built homes take about twice as long as a professional build. Experience with local permitting offices, subs, and suppliers is worth months of saved time. The Montgomery County rules around floodplain, drainage signoff, SJRA permits, and 911 addressing are the kind of thing a local builder handles before you know they exist, and that an out-of-area builder trips on. For more on picking the right team, see our guide on how to choose the right home builder.
Fully custom homes require every decision to be made from scratch. That introduces more opportunities for change orders. Starting from a tested floor plan (semi-custom) gets you most of the personalization with a fraction of the uncertainty. This is the approach we take at Dunn & Stone for most of our builds, and it's why our semi-custom homes usually finish on schedule. See our semi-custom home process for how this works.
Every undecided selection is a ticking clock on a delay. We build a selection timeline into the first 60 days for a reason.
Don't wait until permits are in hand to start loan underwriting. Approvals can take 30 to 60 days. Run underwriting in parallel with design, not after.
Starting a foundation pour in October or November sets you up to complete the weather-sensitive exterior work before the worst of summer heat. July slab pours are doable but require extra cure-temperature precautions.
This sounds obvious, but it's where most schedule slippage starts. Check that your water/sewer letter is current, your address is verified through mc911.org if you're in Montgomery County, your drainage plan meets the latest criteria, and every field on the application is filled out. Our team handles this, but if you're working with a less experienced builder, double-check it.
Even the tightest-run build has unpredictable delays. Plan accordingly. Set your lease expiration, home sale, school transfer, or moving date 30 to 60 days after the projected move-in. Almost every homeowner who has built with us has said afterward, "I'm glad we didn't cut it close."
Waterfront lots on Lake Conroe add a few extra wrinkles that standard Conroe or Woodlands lots don't have. Each one pushes the timeline past the standard 9 to 14 months.
SJRA permitting comes first. Any build within 2,075 feet of the lake requires a San Jacinto River Authority permit as proof of sewer, beyond the standard county permit. First-time waterfront builds should plan for an extra 2 to 4 weeks.
Floodplain compliance comes next. Most lakefront lots have some floodplain exposure. Under the October 2025 regulations, finished floor elevations must be at least one foot above the calculated 100-year high water elevation, and drainage design has to meet the latest Montgomery County Drainage Criteria. This affects foundation height and site prep.
Bulkhead and dock coordination adds a third layer. A bulkhead is the retaining wall that holds back the shoreline. If your project includes a new or replacement bulkhead, boat dock, or boathouse, those permits run on separate timelines and often require marine contractors who book up in spring and summer.
Finally, material delivery access can be tight. Narrow waterfront lots with limited road frontage slow deliveries. Concrete trucks, lumber, and crane access all have to be planned around neighbor easements and, in some communities, restricted work hours.
Realistic Lake Conroe waterfront custom build: 12 to 16 months from contract to keys, even on a 2,500 to 3,500 sq ft home.

Buying is always faster. The real question is whether an existing home actually fits your life. In the Houston area, resale inventory is tight in the most desirable school districts. Many of the homes that are available need significant renovation to match what a new build delivers out of the gate.
For families with a specific layout, lot, or lifestyle need, building usually pays off over 10+ years of ownership. If you need to be in a home in the next 60 days, buying existing is the right answer.

Not every home style takes 9 to 12 months. If speed is your top priority, here are your options from fastest to slowest:
Home typeTypical build timeManufactured or modular home2 to 4 monthsTiny home2 to 4 monthsBarndominium5 to 8 monthsSpec home (existing plan, stick-built)4 to 7 monthsICF (insulated concrete form) home8 to 10 monthsStick-built semi-custom7 to 10 monthsStick-built fully custom10 to 14 monthsLuxury custom (4,000+ sq ft)14 to 18+ months
Each shortcut comes with trade-offs. Modular homes are faster but offer less design flexibility. Barndominiums skip some interior finish work but look different from a traditional home. The right choice depends on what you're optimizing for.
A few real examples of what "unexpected" looks like on a build, drawn from our own jobsites.
The cabinet reorder. A client picked cabinets in week 8 and changed the uppers in week 22 after seeing a new inspiration photo. The eight-week lead time on the replacement order pushed the entire finish schedule by two months. Total delay from one change: 62 days.
The buried debris. A lot we cleared in Magnolia had an old slab buried under three feet of fill. Discovery to removal to a re-approved drainage plan took 18 days. Not catastrophic, but real time we couldn't get back.
The SJRA miss. We took over a build from another contractor where the SJRA permit was never pulled, despite the lot sitting 1,800 feet from Lake Conroe. The homeowner had already paid for architectural plans. We had to redo the sewer plan and resubmit, which added five weeks.
The hurricane pause. September 2024 storms pushed a framing start by 16 days on one project. The lot was too wet to frame safely, and we don't want lumber curing crooked.
The early delivery. A 2,800 sq ft semi-custom build in Pinehurst signed in March, broke ground in May, and handed over keys the following January. That's a 10-month project that closed three weeks ahead of the original schedule because the client locked all selections in the first 30 days and never changed one.
None of the delay stories killed the builds. All added time. Most were avoidable with a more experienced builder on the front end. The early-delivery story shows what's possible when the client and builder are aligned from day one.
"We absolutely love every square foot of our new home! The entire Dunn and Stone team was amazing to work with, as well as very patient and friendly, tending to every small request we had." — Debbie C. (see more reviews)
About 7 to 9 months of construction, plus 1 to 2 months for permitting. Simpler designs on flat, dry lots can finish in 6 months. Complex designs or challenging lots run closer to 10.
About 9 to 11 months of construction, or 10 to 13 months total including permitting. Two-story homes at this size often move slightly faster than single-story because the footprint is smaller.
The U.S. Census Bureau's 2024 data puts the average at 7.7 months of construction, plus 1.4 months for permitting. Custom homes average 9 to 12 months. Owner-built homes average around 14 months.
Finishes. Cabinets, trim, flooring, tile, and paint can account for about a third of the total build. More trades are involved here than anywhere else, which is why scheduling delays hit hardest.
As fast as 2 to 4 months for a manufactured or modular home, or 4 to 7 months for a stick-built spec home. Custom homes of 2,500+ sq ft cannot realistically be built in less than 7 months.
Yes. Most Texas builds lose 2 to 4 weeks to weather per year between hurricane season, spring storms, and summer heat. Foundation work is the most weather-sensitive stage.
Buying is faster. An existing home closes in 30 to 90 days; a custom build takes 9 to 12 months. Building makes sense when resale inventory doesn't match what you want.
10 to 14 months for a custom home in Texas, from contract signing to keys. That includes design, permitting, construction, and closeout. Semi-custom homes from proven plans finish closer to 7 to 10 months.
30 to 50% faster. The builder already owns the lot, has permits in hand, and is working from a plan they've built before.
Only with a manufactured, modular, or tiny home. Stick-built homes of typical family size cannot be completed in 4 months. Anyone promising that on a custom home is cutting corners or counting pre-construction time that hasn't happened yet.
We've been building custom and semi-custom homes in Conroe, Pinehurst, Magnolia, Montgomery, The Woodlands, and around Lake Conroe since 1999. We know what permitting looks like in every jurisdiction in our service area. We know which soils need extra prep. We know how to schedule around hurricane season. And we know what breaks timelines because we've seen all of it.
Our typical semi-custom build runs 9 to 11 months from contract signing to move-in, with fixed prices and fixed schedules. No guessing what's next.
If you're thinking about building on your lot in the Houston area in 2026, we'd be glad to walk you through a realistic timeline for your specific lot and floor plan.
