Build on Your Lot in the Tri-Cities, WA —
Your Land, Your Fully Custom Home
Already own your lot? We’ve built on subdivision lots inside the city and on raw acreage miles from the nearest water line. If it’s your land, we can build your home on it.
We Build on Your Land
We Build on Your Lot — Wherever It Is
A lot of builders in the Tri-Cities will tell you they “do” build-on-your-lot. What they mean is they’ll consider it if the lot is inside a subdivision, utilities are already stubbed in, and the permitting is straightforward. That’s not quite the same thing.
We actually mean it. We’ve built on finished lots inside Pasco and Kennewick subdivisions where the driveway was the only thing the homeowner still needed to figure out. We’ve also built on raw acreage in the Benton City to Prosser corridor — six homes in that stretch alone — where we brought in the power, drilled the well, and installed the septic system from scratch before a single wall went up. We’ve built on hillside view lots in West Richland, on agricultural land in Franklin County, and on rural properties where the nearest neighbor was half a mile away.
Whatever your lot is, the answer to “can you build here?” is almost always yes. But we want to come out and look at it before we say anything else. That site visit is free. And everything else follows from what we find.
"We've gone from raw land and put in the electric power, the septic systems, the wells — in different areas between Benton City and Prosser, six different homes there in that location. And then other houses are in subdivisions."
The Real Difference
What "Build on Your Lot" Actually Means with Anasazi
When a builder says “build on your lot,” it can mean one of three things. Some builders mean they’ll place one of their standard floor plans on your land — same plan they build in every subdivision, just on your property instead. Some builders offer a limited selection of “modifiable” plans. And some builders — the rare ones — mean they will design and build a completely original home, on your specific lot, around your actual needs.
With Anasazi, it’s the third option. We don’t pull out a plan book when you tell us about your land. We start by visiting the property. Then we talk about your family, your life, and what this home needs to do for the next 30 years. Then we design — or start from your plans — and build. No shared plans. No predetermined layout. Your lot, your design, your home.
Build on Your Lot vs. Community Builder
- Community builder: you pick a neighborhood, then a plan, then some finishes — the home was designed before you arrived.
- Build on your lot with Anasazi: you already have (or are finding) your land, and everything — the design, the layout, every finish — is built around you.
- The land comes first. The home fits the land. The design fits your family.
Every Kind of Lot
Subdivisions, Raw Acreage, and Everything In Between
We've built on lots that had every utility already stubbed in and lots where the closest power pole was a quarter mile away. Here's how we approach each.
The Site Visit
The Site Evaluation — What We Check Before We Design Anything
Before we draw a single line on a floor plan, John visits your property. The site shapes every design decision that follows — where the house sits, which way it faces, how the driveway runs. Getting this wrong at the beginning costs you money and time later.

The site visit is free. There’s no commitment. If John finds something that changes the project scope significantly, he’ll tell you honestly — before you’ve spent money designing a home for land that won’t support it.
Permits & Local Process
Land in Franklin or Benton County? Here's What the Permitting Looks Like
We handle every permit for you. Building permits, septic permits, well permits, any county-specific documentation — all of it goes through us. But understanding which jurisdiction your lot sits in matters for your timeline.
Franklin County
Pasco & Surrounding Rural Areas
City of Pasco lots run through the Pasco Community Development Department. Unincorporated Franklin County lots run through the Franklin County Building Division. Rural lots require a septic permit through the Benton-Franklin Health District in addition to the building permit. Franklin County is Washington’s fastest-growing county by percentage — we account for permit office volume in our timelines. City of Pasco permits typically take up to 3 weeks from plan submission.
Benton County
Kennewick, Richland, West Richland, Benton City, Prosser
City lots run through their respective city building departments — Kennewick and Richland both have well-organized permit portals resolving within the standard 3-week window. Rural and unincorporated Benton County lots — including the Benton City–Prosser corridor and Horse Heaven Hills — run through the Benton County Department of Planning. Septic permits require a site evaluation and in many cases a soil perc test by a licensed engineer.
Walla Walla County
Burbank & Two Rivers Area
Lots in the Burbank area near the Snake and Columbia River confluence fall under Walla Walla County jurisdiction. This county permit office is smaller and permit timelines can vary. For clients building in this area, we build extra schedule buffer into the permitting phase.

The Process
The Build-on-Your-Lot Process, Step by Step
Building on your own land has a different shape than buying a lot in a developer’s community. There are more variables, more upfront evaluation, and more decisions before design even begins. Total timeline: approximately 8–10 months. Construction averages 5 months once the slab goes in.
What It Costs to Build on Your Lot in the Tri-Cities
Build-on-your-lot projects have two cost components that community home builders don't deal with: the home itself, and the site development. Understanding both is essential to building an honest budget.
Finished subdivision lot (utilities stubbed)
Minimal. Grading, driveway, rough landscaping.
Lot with power, no sewer/water
Well: $8K–$25K+. Septic: $12K–$25K depending on soil/system type.
Raw rural acreage (no utilities)
Power extension + well + septic + clearing + grading + driveway: $30K–$80K+
The Two-Number Rule
Always get two budgets on a build-on-your-lot project: Budget 1: The home — design, finishes, construction. Budget 2: The land and site development — well, septic, power, clearing, grading, driveway.
-FAQ
Everything You Want to Know Before Your First Call
These are the real questions families ask us. Every answer traces back to John’s actual words — nothing invented.
What does "build on your lot" mean, exactly?
It means you already own (or are in the process of buying) a piece of land, and you want a custom home built on it — rather than buying a pre-built home or a lot in a developer’s community. With Anasazi, it also means the home is fully custom: no pre-designed floor plans placed on your land, no fixed finish options. Your lot, your design.
Can you build on any lot, including raw acreage?
Yes. We have built on finished subdivision lots where every utility was already stubbed in, and on raw rural acreage in Eastern Washington where we brought in power, drilled wells, and installed septic systems from scratch. We’ve completed six homes in the Benton City to Prosser corridor alone — all on raw land. The lot visit tells us what the site needs before we design anything.
Do I need to own the land before we can start talking?
No. We can have a first conversation when you’re still searching. We can help you evaluate parcels before you buy and tell you what the site development implications are for specific lots you’re considering. It’s far better to involve us before the land purchase than after.
Who handles the permits for a build-on-your-lot project?
We do. We handle all permit paperwork: building permit, septic permit, well permit if applicable, and any documentation required by the city or county. Permitting jurisdiction depends on whether your lot is inside a city or in unincorporated Franklin, Benton, or Walla Walla County. City permits in the Tri-Cities typically take up to 3 weeks from plan submission.
What is a site evaluation and is it free?
A site evaluation is a visit from John to your property. He walks the land, identifies optimal home placement, assesses septic and well siting, checks utility access points, evaluates drainage and grading, and notes any setback or HOA restrictions. It typically takes 30 to 60 minutes on-site. It is completely free with no commitment required.
How much does site development cost on raw land?
It depends on what’s already at the lot. A subdivision lot with utilities stubbed needs minimal development. A rural lot with no utilities could require a well ($8,000–$25,000+ depending on depth), a septic system ($12,000–$25,000 depending on soil and system type), power extension, clearing, and grading. We give you the honest combined number — home plus site development — before you sign.
What is a soil perc test, and do I need one?
A percolation (perc) test measures how quickly water drains through the soil on your lot. The Benton-Franklin Health District requires perc test results for rural lots needing a new septic system before they’ll approve a septic design. If your lot hasn’t had one done, we’ll recommend it before design begins — without it, we can’t accurately account for the septic layout in the floor plan.
How long does it take to build a custom home on my lot?
The full timeline from first conversation to move-in is typically 8 to 10 months. Construction itself averages 5 months once site development is complete and permits are issued. Build-on-your-lot projects can run slightly longer than subdivision builds because the site evaluation, any perc testing, and rural permit coordination add time upfront. We account for this in every timeline we give.
What areas in Eastern Washington do you build in?
We build in Pasco, Kennewick, Richland, West Richland, Benton City, Prosser, and Burbank, plus rural areas throughout Franklin, Benton, and Walla Walla counties. We have specific experience in the Benton City to Prosser corridor, Horse Heaven Hills, the West Pasco growth corridors, Canyon Lakes in Kennewick, and Badger Mountain South in Richland. If your land is in this region, call us.
What if I have a septic and well already in place from a previous structure?
Existing septic and well systems may or may not be usable for a new build, depending on their age, condition, capacity, and location on the lot. We have the systems inspected and evaluated early in the process. If they’re adequate for your new home, we design around them. If they need upgrading or replacement, we include that in the site development budget before design begins.
What areas do you build in?
Pasco, Kennewick, Richland, West Richland, Benton City, Prosser, Burbank, and surrounding rural areas of Franklin, Benton, and Walla Walla counties. We also build in nearby parts of Idaho when projects align.
Your land is ready. Let's talk about
what goes on it.
Free first conversation. Free site visit. We’ll tell you honestly what your lot needs and what your home can look like on it.
