Transparent. Fixed-price. Guaranteed.
From first conversation to move-in — here is exactly what working with KĒĒP looks like.
The short answer
KĒĒP ADUs start at $190,000 all-in for a studio, $260,000 for a one-to-two bedroom, and $350,000 for a two-bedroom-plus — each including design, permits, materials, construction, and site work. Your fixed all-in price is confirmed in writing after a free feasibility and site assessment, before any design fees.
01
Feasibility
Week 1–2 · Free · No commitment
We assess your property and deliver a written feasibility report within 48 hours — zoning, setbacks, what unit types are possible on your specific lot, and a preliminary cost range.
What it costs: nothing. What you commit to: nothing.
02
Design & Permits
Months 1–4
We design your unit and manage every permit in every SoCal city. You receive weekly updates. Rejections and resubmissions are handled by us at no extra cost.
Your role: approve designs and answer questions. That’s it.
03
Procurement
Month 3–4 · Runs parallel to permitting
We source and purchase all project materials and coordinate their delivery to your site, using our supplier relationships to keep the build on schedule and on budget.
Because your all-in price is confirmed after the site assessment, you know your number before construction starts, with concealed conditions handled openly rather than as surprise change orders.
04

All prices are all-in — design, permitting, materials, construction, and site work.

Loan payment estimates assume an 8.5% rate over a 30-year term — verify with your lender.
Most homeowners don't pay cash.
HELOC
Home Equity Line of Credit. Borrow against existing equity. The most common financing path for ADU projects.
RenoFi Loan
Based on your post-ADU property value — a higher limit than a HELOC. Designed specifically for renovation and ADU projects.
Construction Loan
Short-term, interest-only during the build. Converts to a standard mortgage on completion. Works well for larger projects.
See how your current payment compares.
You're already paying every month. The question is what it's building.
What are you paying now?
Your $2,400/month could become a ~$1,461/month loan payment — less than you pay now — while building an asset you own.
| Keep paying rent | Build a KĒĒP ADU | |
|---|---|---|
| Monthly payment | $2,400 | ~$1,461 |
| Monthly difference | — | $939 less per month |
| After 10 years | $288,000 spent, nothing owned | Loan paid down + ~$22,800 equity gained |
| What you own at the end | Nothing | An appreciating asset on your own land |
Equity gained is the increase in your property's value — typically less than the full build cost. Loan payment assumes financing the full build cost at an estimated 8.5% rate over 30 years — verify with a lender.

Check my propertyThis is an illustration of how your current monthly payment compares to an ADU loan payment — not financial advice or a guarantee of returns. Loan payment assumes financing the full build cost at an estimated rate; your actual rate, terms, and equity depend on your lender, your property, and market conditions. Consult a lender and tax professional. KĒĒP's fixed price is confirmed in writing after a free feasibility and site assessment.
