What infill developers actually need

The broker who reads the code.

Austin infill development changed materially with the HOME initiative. Phase 1 (effective late 2023) allowed up to three units per SF-zoned lot in many parts of the city. Phase 2 (effective 2024) reduced minimum lot size to 1,800 square feet for small-lot single-family subdivision, opening up compact infill product that was previously not buildable. Site Plan Lite reduced permit lift on under-five-unit projects. Infill Plat simplified the subdivision process for small-lot redevelopment.

Most Austin listing agents have not read the ordinance. They will list a HOME-enabled three-unit project against detached single-family comps in the same submarket and mis-price by 15-25% in either direction. They will misclassify the listing on MLS and miss half the buyer pool. They will fail to position the development against neighboring teardown opportunities that the buyer pool is also evaluating.

Infill development listing requires a broker who has read the ordinance, walked similar projects, and understands the specific buyer profiles for HOME-enabled product (typically investor-buyers, owner-occupants accepting smaller footprints in exchange for closer-in location, and house-hackers). For the full HOME initiative reference, see the HOME initiative developer guide. For the broader builder-services overview, see Austin new construction listing agent.

HOME Phase 2 specifics

What HOME actually changed.

Phase 1

Three units per SF lot

Effective late 2023. Allows up to three units on most traditionally SF-zoned lots in Austin city limits, subject to setbacks and impervious cover limits. Triggered the first wave of three-on-a-lot infill projects from boutique developers in East and South Austin.

Phase 2

1,800 sf minimum lot

Effective 2024. Reduced minimum lot size for small-lot single-family subdivision from previous 5,750 sf to 1,800 sf. Opened up compact-product subdivision on lots that previously could only support a single detached SFR. Triggered the second wave of HOME-enabled product: small-lot detached single-family clusters of 4-12 units.

Site Plan Lite

Streamlined permitting

For projects of fewer than five units, Site Plan Lite reduces the documentation lift required for site plan review. Material reduction in permit-to-build timeline, which materially affects project pro-forma carrying cost.

Infill Plat

Faster subdivision

Simplified subdivision process for small-lot infill redevelopment. Lower-cost path to splitting an existing parcel into multiple buildable lots compared to traditional subdivision. Pairs well with HOME Phase 2 minimum-lot reduction to make small-lot subdivision economically viable.

Pricing HOME-enabled product

Why HOME projects get mis-priced.

The default pricing mistake on HOME-enabled product: anchoring to detached single-family comps in the same submarket. A three-on-a-lot HOME Phase 1 project in 78702 priced against neighborhood detached SFR comps will list 20-30% too high. The buyer pool for the three-unit product is different from the buyer pool for detached SFR; pricing has to follow the actual buyer pool.

HOME Phase 2 small-lot single-family clusters (4-12 detached homes on 1,800-2,500 sf lots each) face a similar but inverse problem: anchoring against townhome comps under-prices them, because each unit is fee-simple detached. The right anchor is small-lot detached single-family in similar Austin submarkets, even if comp count is thin.

Comp depth on HOME-enabled product is improving fast as more projects close. By Q3 2026 there should be enough closed-comp data in central Austin submarkets to anchor pricing on actual HOME-product comps rather than on adjacent product types. Until then, pricing requires manual comp adjustment with a clear methodology.

Working with a broker who has the comp database and the methodology is the difference between pricing-to-sell and pricing-to-pitch. A 15% mis-price on a three-unit HOME project at $750K average is $337K of net error. The cost of getting pricing right is essentially nothing; the cost of getting it wrong is project-killing.

Buyer profile for HOME product

Who actually buys a HOME unit.

The buyer pool for HOME-enabled product splits into three roughly equal segments. Investor buyers (40-45% of HOME unit absorption) buying for rental yield or short-term-rental positioning, prioritizing the cap-rate math and the cost basis relative to expected rent. They tend to buy in the second half of project absorption when initial owner-occupant demand has cleared.

Owner-occupants accepting smaller footprints in exchange for closer-in location (30-35% of HOME unit absorption). Typical profile: working professional, single or couple without kids, willing to give up the 2,400 sf detached SFR in Cedar Park for the 1,200 sf HOME unit in 78702 with the 12-minute commute. They tend to buy in the first 30-60 days of project listing if pricing is right.

House-hackers and small investors (20-25% of HOME unit absorption) buying owner-occupant on one unit of a three-unit project and renting the other two. Workshop FHA financing on this segment is common. They tend to buy on the first one or two units of a three-unit project so they can lock in the owner-occupant unit and start the rental cash flow on the other two as soon as possible.

Listing strategy on HOME projects has to address all three segments because no single segment is deep enough to absorb a full project alone. MLS classification, photography, and broker positioning each get tuned to draw all three pools. Generalist agents typically write the listing for one segment (usually owner-occupants) and miss 60-70% of the actual buyer pool.

Common Questions

Infill Development Broker FAQ.

Austin's HOME initiative is a city-wide land-use change that came in two phases. Phase 1 (late 2023) allowed up to three units per traditionally SF-zoned lot. Phase 2 (2024) reduced minimum lot size to 1,800 sq ft for small-lot single-family subdivision, plus introduced Site Plan Lite for under-5-unit projects and Infill Plat for streamlined subdivision. Together they materially expanded what is buildable on Austin infill parcels.
HOME-enabled product (three-on-a-lot, small-lot detached clusters, etc.) prices differently than traditional detached single-family. Anchoring to neighborhood SFR comps mis-prices by 15-25%. The buyer pool is different (investor buyers, smaller-footprint owner-occupants, house-hackers), and listing strategy has to address all three segments. Working with a broker who has read the ordinance and tracked HOME-product absorption matters more on these projects than on traditional spec listings.
Site Plan Lite is a streamlined site plan review process for Austin development projects of fewer than five units. Reduces the documentation and review lift compared to standard site plan review, which materially compresses permit-to-build timelines. Most boutique infill projects in Austin now go through Site Plan Lite rather than full site plan review.
Infill Plat is a simplified subdivision process for small-lot infill redevelopment in Austin. Allows splitting existing parcels into multiple buildable lots with lower-cost permitting compared to traditional subdivision. Pairs with HOME Phase 2 minimum-lot reduction to make small-lot subdivision economically viable.
Most Austin HOME-enabled infill projects are 2-12 units. Three-on-a-lot HOME Phase 1 projects (most common): 3 units. Small-lot single-family clusters under HOME Phase 2: typically 4-12 units. Larger infill projects (12-30+ units) usually involve multiple parcel assembly and use traditional subdivision rather than Infill Plat. The 2-12 unit range is where boutique infill developers live and where the listing-broker specialty is most valuable.
Direct reading of the Austin city land development code, attendance at city council updates as the ordinance has been amended, walking active HOME-Phase-1 and HOME-Phase-2 projects, and ongoing absorption tracking on HOME-product MLS listings. The HOME initiative is recent enough that even most active Austin listing agents have not read the ordinance carefully; that information asymmetry is the basis for the specialist positioning on this page.
