Financing & Return on Investment

Financing Options

🏦

Construction Loans

Short-term financing during the build, converts to permanent

Construction loans release funds in draws tied to project milestones — foundation, framing, rough-in, finish — rather than a single lump sum, so you only pay interest on what's been disbursed so far. Most convert automatically into a standard mortgage once the certificate of occupancy is issued, folding your construction debt into one permanent loan without a second closing. Best fit for larger additions or ground-up ADUs where the loan amount exceeds what a HELOC or personal loan can cover.

🏠

HELOC

(Home Equity Line of Credit) — flexible, draw-as-you-go financing

A HELOC gives you a revolving credit line secured by your home, letting you draw funds as project costs come in rather than borrowing the full amount upfront. Interest is charged only on what you've drawn, and most lines carry variable rates tied to the prime rate. This tends to be the fastest option to arrange since it uses equity you already have, making it a common choice for remodels and smaller additions where speed matters.

🏗️

FHA 203(k) Renovation Loan

Roll your home purchase or refinance and renovation costs into one mortgage

A 203(k) loan combines financing for the home itself with financing for the renovation in a single mortgage, requiring as little as 3.5% down. The Standard 203(k) covers structural work — room additions, foundation repairs, moving load-bearing walls — with no renovation cost cap beyond your county's FHA loan limit, while the Limited 203(k) is a lighter-weight option for non-structural upgrades under $75,000. This route works whether you're buying a fixer-upper or refinancing a home you already own to fund the project; a HUD-approved 203(k) consultant oversees the work, and renovations must be completed within six months.

Lender Partners

Connecting you with lenders experienced in design-build project financing

We can connect you with lenders we trust who are familiar with financing additions, remodels, and ADU construction — not just general-purpose mortgage lending. Ask us for a referral when you're ready to explore your options.

How It Works

Our 5-phase design-build process takes you from first walkthrough to a completed project — whether that's an addition, a remodel, or an ADU.

1

Site Visit & Scope

We walk the property with you, talk through what you're trying to accomplish, and get a feel for the site's constraints. You'll leave with a rough sense of what's realistic for your budget.

  • ✓ Property walkthrough and goal discussion
  • ✓ Setback, zoning, and existing-structure review
  • ✓ Preliminary conceptual budget range
  • ✓ Request existing plans or a new survey plat if needed

Timeline: 1-2 weeks

📋

What to Expect

A site visit, an honest conversation about your goals, and a realistic first read on budget — no pressure, no hard sell.

📐

Design Development

Measurements, floor plans, elevations, and a cost range you can actually plan around — refined until it fits.

2

Design Development

We measure and document the existing space, then develop a design concept. You review and refine until the design fits both your goals and your budget.

  • ✓ Detailed measurements and site documentation
  • ✓ Floor plans and elevations
  • ✓ Preliminary cost range based on the design concept
  • ✓ Revisions until the design and budget both work

Timeline: 3-6 weeks

3

Fixed-Price Agreement

Once the design is approved, we prepare final construction drawings and finalize a fixed-price contract based on the completed plans — no guessing games on cost once construction starts.

  • ✓ Final construction drawings and specifications
  • ✓ Fixed-price contract based on final plans
  • ✓ Clear scope and selections locked in before signing

Timeline: 2-3 weeks

📝

No Surprises

A fixed-price contract built from your final, approved plans — the cost is set before a single wall comes down.

🔨

Permitting & Construction

As the licensed contractor of record, we handle permitting and coordinate the trades on your project, keeping you updated throughout.

4

Permitting & Construction

With the contract signed, we submit for all required permits and begin work on schedule. As the licensed contractor of record, we coordinate the trades and subcontractors on your project and keep you updated on progress throughout.

  • ✓ Permit submission to local authorities
  • ✓ Site preparation and foundation work — adequacy certified by a licensed Professional Engineer when required
  • ✓ Framing, electrical, and plumbing rough-in
  • ✓ Insulation, drywall, and interior finishes
  • ✓ Regular progress updates and photos

Timeline: 3-7 months

5

Walkthrough & Handoff

Before we call it done, we walk the finished space with you — checking every detail against the plan — and hand over keys, documentation, and any warranty information.

  • ✓ Final quality walkthrough with you
  • ✓ Certificate of occupancy or final approved inspections from the county
  • ✓ Warranty and maintenance documentation
  • ✓ Ongoing support after handoff

Timeline: 1-2 weeks

🗝️

Move-In Ready

Final walkthrough, keys, and documentation — your project is ready for occupancy or rental.

Frequently Asked Questions

What makes semi-custom different from fully custom?

Semi-custom ADUs use pre-designed floor plans that have been optimized and pre-approved, reducing design time and permitting delays. You can still customize finishes, fixtures, and some layout elements, but the core structure is standardized for efficiency.

Do you only build ADUs?

No — ADUs are one of three service lines. We also design and build home additions (first and second-floor additions, primary suite additions) and whole-home remodels (kitchens, bathrooms, and full-house renovations). Additions and remodels are custom design-build projects quoted individually, rather than semi-custom.

How long does the entire process take?

From initial consultation to move-in ready, most projects take 6-12 months. The timeline depends on project scope and size, local permitting requirements, and any site-specific challenges. We provide detailed timelines during the consultation phase.

Do you handle all permits and approvals?

Yes, we manage the entire permitting process including architectural plans, structural engineering, and all city approvals. Our team has relationships with local building departments to expedite the process.

What's included in your pricing?

Our pricing includes design, permits, construction, standard finishes, and a 1-2 year warranty. Additional costs may include utility connections, site preparation for challenging lots, and premium finish upgrades.

What's NOT included in the base pricing?

To ensure transparency, here are common additional costs that may apply:

  • • Utility connections and meter installations (electric, water, sewer, gas)
  • • Extensive site preparation (grading, retaining walls, tree removal)
  • • Premium finishes and appliance upgrades
  • • Landscaping and hardscaping restoration
  • • Structural modifications to existing home (if needed)
  • • Engineering plans and structural calculations (if required by jurisdiction)
  • • Printing and graphics for plan sets and permit documents
  • • Survey and soil testing (if required by jurisdiction)
  • • Impact fees and development charges (varies by city)

We provide detailed cost breakdowns during the consultation so there are no surprises.
