What a 78704 Build Timeline Actually Looks Like in 2026
Developer Intelligence · August 2026
The short answer: plan on 14 to 18 months from the first design meeting to move-in. Design and documentation runs three to four months, permitting is faster than it was — Austin cut residential review timelines on July 1, 2026 — and construction runs 10 to 12 months. The number people get wrong is permitting, because the published review time measures one review cycle, not the time it takes to get a permit in hand.
Almost every owner who has been through a custom build in central Austin was surprised by the schedule, and almost none of them were surprised in the same place. Here's the sequence with realistic durations, where 78704 projects actually lose time, and what changed at the City five weeks ago that makes the front half of this faster than it was last year.

The Five Phases
Phase | Typical Duration | What Extends It |
|---|---|---|
Feasibility and due diligence | 2 to 6 weeks | Waiting on surveys; discovering a recorded deed restriction or overlay late |
Design | 2 to 4 months | Owner indecision, mid-stream program changes, envelope iterations on constrained lots |
Permitting | 1 to 4 months | Correction cycles — the single biggest variable. Tree, environmental or drainage review adds groups. |
Construction | 10 to 12 months | Slope, trees, weather, change orders, long-lead materials, selection delays |
Punch and closeout | 3 to 8 weeks | Backordered fixtures, inspection scheduling, unresolved punch items |

The Permitting Number Everyone Quotes Wrong
Someone will tell you Austin residential review takes ten business days. That's roughly right and completely misleading.
Ten business days is the target for one review cycle. What happens at the end of that cycle is usually not approval — it's comments. Your design team responds, resubmits, and another review clock starts. Two or three correction cycles is normal on a custom project, and each one carries both the City's review time and however long your architect takes to respond.
That's how a "ten business day" review becomes two to four months from application to permit in hand. The City's clock is running well; the round trips are what accumulate.
The other thing that stretches it: additional review groups. A project needing tree review, environmental review, or drainage review picks up additional disciplines, and those operate on their own schedules. On a Zilker or Barton Hills lot with protected trees, assume that applies to you.
The cheapest schedule insurance available: a complete, coordinated submittal. The correction cycle you don't trigger is worth more to your calendar than any expediting service. Ask your architect directly how many correction cycles their last three Austin residential submittals took — the answer varies widely between firms, and it is a legitimate factor in who you hire.
What Changed on July 1, 2026
Austin Development Services reduced residential plan review timelines effective July 1, 2026. As published, new construction and additions target ten business days; interior remodels, demolitions and fence permits target five; update submittals target seven. Qualifying minor repairs under the express program can be same-day, and S.M.A.R.T. Housing projects run at five business days.
If you got quoted a permitting timeline based on 2024 or 2025 conditions, it's worth revisiting. The front half of a 78704 project is genuinely faster than it was, and that has a real effect on carry cost — every month shaved off the pre-construction phase is a month you're not paying interest on a land loan.
Worth noting the flip side: faster review does nothing about correction cycles, which remain the dominant variable. A shorter clock that runs three times is still three round trips.
Two Options Worth Knowing About
Expedited Building Plan Review. A premium City program that puts a full team of reviewers — zoning, arborist, building and fire — in a single session with your design team. The value is collaborative problem-solving and on-the-spot decisions rather than a comment letter you interpret two weeks later. It covers new construction, additions and remodels for single-family through four-unit projects on one lot. Projects requiring drainage review generally aren't eligible.
Self-certification. Austin offers a Certificate of Compliance program allowing Texas-licensed architects and certified building designers to self-certify certain qualifying projects. If your architect participates and your project qualifies, this can meaningfully compress the review phase. Ask about it early — it's a question worth raising when you're selecting a design team rather than after documents are complete.
Trying to work out whether your timeline is realistic?
Schedule drives carry cost, and carry cost drives whether a project pencils. The Davis Agency works with the builders, architects and consultants running these projects across 78704 and can tell you whether the timeline you've been quoted matches what's actually happening.
Where 78704 Projects Actually Lose Time
Design iteration on constrained lots. When impervious cover and FAR are both binding and a heritage oak sits in the buildable area, the first scheme rarely works. Two or three rounds is normal, and each one costs weeks. This is why the tree survey belongs before design, not after — the single highest-leverage sequencing decision in the whole project.
Owner decision latency. The most expensive thing an owner does is take four weeks to answer a question that's holding up a trade. Builders track this, and it's the difference between a project that finishes at seventeen months and the same project at twenty-two. Decide who has final say before you start, and hold to a response window.
Selections made late. Tile, plumbing fixtures, appliances, lighting, cabinetry hardware — all of it has lead times, and some of it has long ones. A selection made at the deadline is fine. A selection made three weeks after the deadline on an item with a twelve-week lead time is a delayed project.
Concealed conditions. Rock where the excavation assumed soil. A utility in an unexpected place. A structural condition revealed at demolition. On sloped 78704 lots with mature trees, these are common enough to plan for rather than hope against.
Weather. Central Texas gives you wet stretches that stop concrete and dirt work outright. Any schedule with zero weather allowance is a schedule that will slip.
Building the Schedule Into Your Decisions
Two practical consequences of a 20 to 30 month horizon.
First, where do you live during it? If you're selling your current house to fund the build, you're renting for two years. That's a real cost and it belongs in the project budget rather than being discovered in month three.
Second, your financing has to survive it. A construction loan carrying for two-plus years is exposed to rate movement, and the take-out permanent financing gets underwritten in a market you can't see from here. Talk to your lender about that exposure at the start, not at framing.
And if the timeline is the dealbreaker — if you need to be in a house in nine months — that's genuinely useful information. It means you're buying, not building, and knowing that before you've paid for schematic design saves real money.
Frequently Asked Questions
How long does it take to build a custom home in Austin?
Plan on 14 to 18 months from the first design meeting to move-in. That breaks down roughly as two to six weeks of feasibility and due diligence, four to eight months of design and construction documents, one to four months of permitting, 10 to 12 months of construction, and three to eight weeks of punch and closeout. Constrained sites with slope, protected trees or environmental review sit at the longer end.
How long does Austin residential plan review take?
Austin Development Services reduced residential review timelines effective July 1, 2026. As published, new construction and additions target ten business days, interior remodels, demolitions and fence permits target five, and update submittals target seven. Those figures describe a single review cycle. Because most custom projects go through two or three correction cycles, total time from application to permit issuance typically runs one to four months.
What is the fastest way to get a residential permit in Austin?
Submit complete, coordinated documents the first time — avoided correction cycles save more calendar than any other single factor. Beyond that, the City offers an Expedited Building Plan Review program placing zoning, arborist, building and fire reviewers in a single session with your design team, and a Certificate of Compliance program allowing self-certification by Texas-licensed architects and certified building designers on qualifying projects.
Why do custom home builds take longer than the builder says?
The most common causes are owner decision latency, late selections on long-lead items, design iteration on constrained lots, concealed site conditions revealed during excavation or demolition, and weather. Of these, owner response time is the one most within your control and the one that most reliably separates a seventeen-month build from a twenty-two-month one.
