The HOME Initiative Pushed Austin ADU Permits Up 340 Percent
In the two years after Austin's HOME Initiative took effect, ADU permits jumped 340 percent, more than 1,200 new units approved in a city that had spent decades treating backyard units as an afterthought. That single ordinance change is the reason Austin now has the most ADU-friendly rulebook of any metro in Texas, and it's reshaping what homeowners here are building.
What the HOME Initiative Actually Changed
Austin passed HOME in two phases, Phase 1 in December 2023 and Phase 2 in May 2024. Together they cut the minimum lot size for a residential unit to 2,500 square feet, allow up to three units on a lot that used to hold one house, and eliminated both the off-street parking requirement and the owner-occupancy rule that used to scare off investors and second-home builders alike. Those four changes, stacked together, are what produced the 340 percent surge in ADU permits. Most cities that loosen one ADU rule see a bump. Austin loosened four at once, and the permit data shows it.
We built our ADU Plans & Design service around exactly this kind of shift. Lot-size math, unit count, and parking no longer box in a design the way they did two years ago, so the drafting question in Austin right now is less "can I fit an ADU" and more "how do I make the most of three units on one lot."
Austin's Building Market by the Numbers
993,588City population, 2024, growing 0.4% a year
2.55MMetro population, up 2.3%, 58,000+ added
32,294New residential units authorized metro-wide in 2024, #6 nationally
28.6-28.8Permits per 1,000 existing homes, #2 among major U.S. metros
The city itself is barely growing, up just 0.4 percent, but the metro is adding more than 58,000 people a year and authorizing new housing at a rate matched by almost no other large metro in the country. That combination, a mature urban core with a fast-growing ring around it, is exactly the setup that drives infill projects: additions, ADUs, and lot splits inside city limits, paired with new custom builds further out. Austin's per-capita permit rate, 28.6 to 28.8 permits for every 1,000 existing homes, ranks second nationally. Only one metro built more relative to its existing housing stock last year.
A Crowded Field, and Where Remote Drafting Fits
Austin already has a dense bench of boutique design-build shops and CAD studios, firms like Austin CAD Services, Austin Floor Plans, Shiflet Group Architects, and Jenkins Design Build all compete for the same custom-home and remodel clients. That's a sign of real demand, not a reason to avoid the market. What it does mean is that turnaround and clarity matter more here than in a market with fewer options. We serve Austin homeowners, builders, and contractors remotely, working the same drawing set through revisions by phone, email, and video review, without adding a local firm's overhead to your invoice.
What Falling Prices Mean for Your Build Decision
Zillow puts the average Austin home value at roughly $512,937 to $567,739, down 5 to 7 percent year over year, the market's 12th consecutive month of annual price decline. When resale values are soft, building on land you already own, or converting a garage or backyard into a second unit, starts to look better than buying up into a shaky market. That's part of why ADU demand accelerated at the same time prices softened. Owners are optimizing the lot they have instead of trading into a new one.

The Drafting Work Austin Is Actually Ordering
Given the HOME Initiative and the price trend above, three services are doing the heavy lifting for Austin clients right now.
ADU Plans & Design
With parking and owner-occupancy rules gone and up to three units now allowed per lot, ADU projects in Austin have shifted from a niche request to a mainstream one. We draft units sized to the 2,500-square-foot lot minimum and structured for permit approval under the current ordinance.
Custom House Plans
The metro's #2 national ranking in per-capita permitting means a lot of ground-up building is still happening outside the urban core, where lots are larger and custom design still beats a stock plan for site-specific work.
Home Additions & Remodel Drafting
With home values down for a full year running, more owners are choosing to expand in place rather than sell into a soft market. Addition and remodel drawings are picking up the slack that a slower resale market leaves behind.
For any of these, a Permit-Ready Drawings & As-Builts package keeps the drawing set aligned with what the city actually requires to issue a permit, which matters more in a market processing this many applications.
Austin ADU and Drafting FAQ
Does Austin allow ADUs, and how easy is it to permit one?
Yes. Austin has the most ADU-permissive rules of any Texas metro. The HOME Initiative, passed in two phases (December 2023 and May 2024), dropped the minimum lot size to 2,500 square feet, allows up to three units on a single-family lot, and removed both the parking requirement and the owner-occupancy requirement. In the two years after passage, the city saw more than 1,200 ADU permits, a 340 percent increase.
Is there a Texas state law that requires cities to allow ADUs?
No. Texas has no statewide ADU mandate. Every city sets its own rules. A 2025 bill, SB 673, would have preempted local ADU restrictions statewide. It passed the Texas Senate but died in the House on June 2, 2025. That means Austin's local ordinance, not a state law, is what governs your project.
Do you have an office in Austin?
No. Apex Drafting is a fully remote drafting company. We serve Austin homeowners, builders, and contractors from our Colorado City, Arizona base, coordinating entirely by phone, email, and video. Every set of drawings is built to meet the same local code and permitting requirements a nearby drafter would use.
Why are home values in Austin dropping, and does that affect whether I should build?
Zillow puts Austin's average home value around $512,937 to $567,739, down roughly 5 to 7 percent year over year, the market's 12th straight month of annual decline. For owners, that price softness is one reason additions, ADUs, and remodels are drawing more interest than buying up. Building on a lot you already own, or adding a second unit for rental income, sidesteps a resale market that is currently working against sellers.

Austin As-Built Drawings for Remodels and Additions
An Austin remodel is easier to coordinate when the design team starts from the house that exists today. Existing-condition or residential as-built drawings can document current walls, openings, stairs, fixtures, roof relationships, and selected exterior information before proposed work is layered onto the set.
The City of Austin's Residential Plan Review guidance describes floor-plan information such as drawing scale, room labels, wall measurements, ceiling heights, openings, fixtures, and safety devices. It calls for existing and proposed floor plans where walls, windows, doors, or fixtures change. The city's Forms and Applications page is the stable starting point for the current remodel application.
That does not mean every Austin project needs the same "as-built" package. A kitchen layout may need a focused measured plan, while an addition can require floor plans, elevations, sections, roof information, site coordination, and structural input. Apex defines the downstream use and sheet list before field capture begins.
Exterior and Roof Context
Visible elevations, roof forms, heights, and tie-in conditions when the proposed work depends on them.
Proposed-Work Base
A coordinated starting file that can feed addition and remodel drawings or a permit package.
Before requesting a quote, compare as-builts vs. record drawings, review the measurement checklist, and see Apex's residential as-built drawing service.
When are existing-condition drawings useful for an Austin remodel?
They are useful when proposed work changes walls, openings, fixtures, or other existing conditions that the plan review needs to compare. Austin's residential guidance calls for existing and proposed floor plans in applicable remodel scopes, but the exact package depends on the project.
