If you’re considering building an ADU in Temecula or Murrieta, you probably have questions. Here’s a simple breakdown of what to consider before getting started.

1. Site Evaluation
Walk your property and identify potential ADU spots. A spare bedroom and bath might work for a junior ADU. Converting a garage is a cost-effective option that doesn’t cut into living space. If you have more budget and yard space, a detached ADU offers more privacy and rental potential. We offer free online consultations to help assess your site.

2. Estimate Costs
Your budget will guide your decisions.
• Hard costs: construction, usually $225–$350 per sq ft. Use $280/sq ft as a safe estimate.
• Soft costs: design, permits, engineering.
Add these together to set a realistic ballpark budget.

3. Explore Financing Options
Most homeowners use a HELOC or refinance to fund the project. You can also combine personal savings or help from a family member if it’s being built for them. Talk to your bank to understand your borrowing power.

4. Consider Return on Investment
Building an ADU adds value. If your home is worth $400/sq ft and you build a 500 sq ft ADU at $250/sq ft, you’re adding $200,000 in value for a $125,000 investment. Renting it out? Your tenant may cover the loan with their rent. Run the numbers with your advisor.

5. Start Design Plans
With a budget and site plan in place, it’s time to design. Decide how you’ll use the space, your target size, and whether it’s attached, detached, or garage conversion. Share that with your designer to draft your plans.

6. Get Contractor Bids
Once you have plans, get at least three bids from a qualified ADU builder or a trusted General Contractor in Temecula, CA. Do this before you submit to the city so you can adjust designs if needed.

7. Submit to the City
Submit your ADU plans to Temecula or Murrieta. The city review process can take up to 60 days. After revisions, you’ll get your building permit and construction can begin.

We’ll cover each of these steps in more depth in future posts.
