San Dimas offers a mix of established neighborhoods and hillside lots where custom builds make sense. Many borrowers here use construction loans to tear down outdated homes or build on vacant parcels in the foothills.
Construction financing works differently than purchase loans—you draw funds in stages as the build progresses. Most lenders require 20-25% down and inspect at each phase before releasing the next payment.
The process takes 12-18 months from loan approval to final conversion. You'll pay interest only on drawn funds during construction, then convert to a permanent mortgage when the certificate of occupancy is issued.
Construction Loans in San Dimas
Lenders want 680+ credit and verified construction experience from your builder. They'll scrutinize the contractor's license, insurance, and track record more than they would on a standard purchase.
You need detailed architectural plans, engineering reports, and a line-item budget before closing. Incomplete plans kill deals—lenders won't fund a project they can't properly underwrite.
Expect debt-to-income under 43% based on the future permanent payment, not the construction interest. Reserve requirements run 6-12 months of payments depending on project complexity.

Most big banks exited construction lending after 2008. Regional banks and specialty lenders now dominate this space, each with different comfort levels on project size and borrower experience.
Some lenders cap loans at $2 million while others go higher for qualified borrowers. A few will finance first-time builders, but most require you've completed at least one prior project or hire a general contractor with strong references.
Portfolio lenders offer the most flexibility on unique designs or non-standard lots. They keep loans on their books instead of selling them, so they can bend guidelines for strong borrowers.
The builder you choose affects your loan more than any other factor. Lenders maintain approved contractor lists and won't fund projects with unlicensed or uninsured builders, regardless of your financial strength.
Budget overruns kill construction loans. Build a 15% contingency into your budget—inspectors will catch issues, material costs fluctuate, and permitting delays cost money even when no work is happening.
Single-close construction loans cost more upfront but save hassle. You close once and convert automatically to permanent financing. Two-close loans require requalifying after construction, which can fail if rates spike or your income changes.
Bridge loans work when you need to buy land before construction financing is ready. You pay higher rates for 6-12 months, then refinance into the construction loan once plans are finalized.
Hard money makes sense for fix-and-flip projects or when you can't qualify for traditional construction financing. Rates run 9-12% but approval is faster and credit requirements are looser.
Jumbo construction loans apply when your project exceeds conforming limits. They carry stricter reserve requirements and lower loan-to-cost ratios, typically maxing at 75% instead of 80%.
San Dimas sits in LA County, where permitting can stretch 3-6 months even for straightforward projects. Factor this into your construction timeline—delayed permits mean extended interest-only payments before building starts.
Hillside lots in San Dimas trigger additional engineering requirements and geological surveys. Lenders require soils reports and sometimes seismic certifications, adding $15,000-$30,000 to upfront costs.
HOA approval is required in many San Dimas neighborhoods before construction begins. Some associations restrict build hours, exterior colors, and architectural styles—issues that can derail financing if discovered late.
Most lenders cap construction loans at 75-80% of completed appraised value. You'll need 20-25% down plus funds to cover closing costs and initial draws before the first inspection.
You'll need to bring additional cash to cover overruns. Lenders won't increase the loan mid-project, so maintain a 15% contingency fund for unexpected costs.
Most lenders require a licensed general contractor. A few portfolio lenders allow owner-builders if you have prior construction experience and strong financials.
Expect 45-60 days from application to closing. The process is slower than purchase loans because lenders review plans, contractor credentials, and budgets in detail.
Construction loan rates typically run 1-2% above conforming mortgage rates. Rates vary by borrower profile and market conditions based on credit, experience, and project complexity.
