Thinking about building a custom home in Boerne? It is exciting to picture the finished house, but in 78006, the path from raw land to move-in day starts long before floor plans and finishes. If you understand the local steps early, you can make better decisions, avoid common delays, and move forward with more confidence. Let’s walk through what your Boerne custom home journey really looks like.

Why land readiness comes first

In Boerne, a custom home project is not only a design project. It is also a jurisdiction, access, utility, drainage, and sometimes septic project.

Before you lock in a home design, you need to know whether your property is inside Boerne city limits, in the city’s ETJ, or in unincorporated Kendall County. That one detail affects where permits are filed and which rules apply to your project.

For projects in the City of Boerne, new residential and commercial permits are processed through My Government Online as of July 14, 2025. In unincorporated Kendall County, development, driveway, floodplain, and septic requirements follow county rules instead.

This is why the earliest phase matters so much. A beautiful plan on paper only works if the lot can support the home you want to build.

Start with jurisdiction and site facts

The first step is getting clear on the property itself. You want current, accurate information before design begins.

A current survey, plat, or deed information can help confirm boundaries, easements, and important site details. If septic may be needed, site evaluation and soil analysis also become part of the picture.

Floodplain status matters early too. Kendall County directs owners to FEMA flood map resources, and Boerne lists floodplain development as a permit that may be required. If floodplain issues show up late, they can force design changes and affect schedule.

Driveway access is another early checkpoint that often surprises people. Kendall County states that a driveway permit is the first permit to obtain for a development when the driveway connects to a county road, and an address will not be assigned until that driveway permit is obtained.

Confirm utility service early

One of the biggest mistakes in a raw-land project is assuming utility service is available just because it is nearby. In Boerne, utility planning needs to happen early and carefully.

Boerne Utilities says the city owns electric, water, wastewater, and natural gas systems. At the same time, service is not automatic outside city limits, and the city notes that water and wastewater service is within city limits and WCID #3, also known as Esperanza.

The city also asks owners or designers to map utility locations and easements before utility design begins. That means your utility plan should be coordinated before major design decisions are finalized.

If city water or wastewater is not available, your project may need to be planned around septic and possibly other utility arrangements. Knowing that upfront helps shape the house layout, site plan, and budget.

Know when septic may be required

Many Boerne-area landowners need to plan for an on-site sewage facility, also called an OSSF. If your lot is outside city wastewater service, this can become a major part of the build strategy.

TCEQ says nearly all OSSFs require a permit before construction and must be based on a site evaluation. Kendall County also requires an OSSF permit, and the county says complete septic applications should be approved or denied within 30 days.

If an aerobic system is required, there are added closeout items. Kendall County requires an affidavit to the public and a maintenance contract for aerobic systems.

This is one reason septic planning should happen before the home footprint is fixed. The disposal area, soil conditions, and lot layout all affect what is possible.

Understand drainage and floodplain impacts

Drainage is not a minor detail in a custom build. It can affect grading, hardscape, driveway size, and overall site cost.

Boerne says new-development drainage needs are addressed through on-site detention and off-site mitigation. The city also notes that its stormwater fee is based on impervious cover.

That means choices like larger driveways, patios, and other hard surfaces can influence both design and budget. If your property also has floodplain exposure, those constraints need to be understood before the plan is finalized.

A clear site strategy helps prevent expensive redesigns later. It also gives you a more realistic picture of what it takes to make the land truly build-ready.

The five phases from land to keys

A custom home journey in Boerne usually makes the most sense when you think about it in five phases. Each step builds on the one before it.

1. Pre-design and feasibility

This is the planning stage where the goal is to turn raw land into a workable building plan. You confirm zoning and rights of use, utility availability, driveway access, floodplain conditions, and septic needs before you finalize floor plans.

Boerne’s Development Services guidance says zoning, variances, and rights of use must be approved before starting a project. Boerne Utilities also asks owners or designers to attend a pre-design meeting before utility distribution design begins.

For many homeowners, this phase creates the clarity needed to move forward with confidence. It is where you learn what the lot can support and what extra coordination may be required.

2. Design and permit assembly

Once site facts are clear, the design can respond to them. This is when your home layout, site plan, and required application materials start coming together.

For city projects, contractors must be registered with Boerne to work in the city limits and submit permit applications. For county projects, Kendall County requires a preapplication meeting at least 7 days and no more than 3 months before a Development Permit submittal, though that meeting is not required for a Minor Residential Development Permit.

This phase is where organization matters most. Incomplete applications can slow everything down, and Kendall County states that incomplete applications are not processed.

3. Approvals and release to build

After submittal comes review. Timing varies based on completeness, revisions, and project complexity, but local review windows help set expectations.

Boerne’s current permit review timeline lists residential new-construction permits at 21 days for first review and 14 days for secondary review. Kendall County says OSSF permit decisions are due within 30 days of receiving a complete application.

Other permits may also be needed depending on the site. Boerne notes that tree removal, grading, right-of-way work, and floodplain development can each trigger additional approvals.

4. Sitework and vertical construction

Once permits are approved, the project moves into physical construction. The sequence usually includes clearing, grading, driveway construction, utility rough-ins, foundation work, framing, trades, insulation, drywall, finishes, and inspections.

In county areas, it is important to remember that a Development Permit does not itself authorize driveways, right-of-way work, or on-site sewer facilities. Those remain separate coordination items.

Before any digging begins, Texas law requires a call to 811. Boerne says its crews will locate underground lines within two business days after Texas 811 notifies the city.

5. Closeout and move-in readiness

The last phase is more than a final walkthrough. It includes final inspections and the paperwork needed to wrap up the project properly.

Boerne says final inspections occur once construction is complete, followed by issuance of a Certificate of Occupancy if applicable. For county septic systems, closeout may also include keeping required records on file, especially for aerobic systems.

This stage is where a disciplined process pays off. When approvals, records, and final items are handled clearly, your move-in experience is smoother.

Timing issues that can affect your schedule

No two custom builds follow the exact same timeline, but a few local issues tend to have an outsized impact on schedule. Knowing them early helps you plan better.

One of the biggest factors is application completeness. Kendall County does not begin review until an application is complete, and Boerne notes that permit timelines vary based on revisions and complexity.

Permit expiration windows matter too. Kendall County says development permits, driveway permits, and septic permits can expire after one year. If a project stalls, renewals or resubmittals may become part of the process.

Separate approvals can also add time if they are discovered late. Floodplain permits, tree removal permits, grading needs, right-of-way work, utility coordination, and septic requirements all have the potential to affect schedule.

What to bring to your first builder meeting

A productive first meeting starts with the right documents and questions. The more clearly you can define the site, the more useful the conversation will be.

Bring any materials that help establish legal access, physical constraints, and utility conditions, such as:

• Current survey, plat, or deed information
• Known easements
• Utility-service information
• Floodplain information or FEMA map results
• Septic site evaluation or soil analysis status, if available
• Known driveway access questions or road-connection constraints

It also helps to ask practical questions that shape the early roadmap, including:

• Which jurisdiction applies to this tract?
• Which office or portal will handle permits?
• Is water and wastewater service available?
• Will the project need septic?
• What additional permits might be triggered by floodplain, grading, tree removal, or right-of-way work?
• What is the plan if the project extends beyond a one-year permit window?

These questions help turn uncertainty into a workable plan. They also make it easier to align budget, design, and timing from the start.

Why an integrated process matters

When you build on raw land in Boerne, early decisions affect almost everything that comes after. Site constraints shape design. Utility service affects layout. Permit requirements influence schedule. Drainage and access can change budget.

That is why many homeowners value a design-build approach. With one accountable team guiding planning, sitework, design coordination, and construction, you can reduce handoff issues and keep communication clearer throughout the process.

For a project as personal and significant as a custom home, clarity matters. A steady process, realistic expectations, and early problem-solving can make the path from land to keys feel far more manageable.

If you are planning a custom home in Boerne or elsewhere in the Texas Hill Country, BGA Design & Build can help you think through the site, the process, and the next steps with a communication-first design-build approach.
