Hillsborough has some of California's strictest building codes and design review processes. Most construction projects here involve custom estates on existing lots or tear-downs of older homes.
Lenders know Hillsborough projects take 18-24 months from groundbreaking to certificate of occupancy. Rate cuts expected later in 2026 may improve borrowing costs, but construction timelines here won't change.
Construction Loans in Hillsborough
You need pristine credit (720+) and significant reserves — typically 12-18 months of construction costs in liquid assets. Lenders want to see you can cover overruns without scrambling.
Expect to put down 25-30% of total project cost. Some lenders require the land owned free and clear before they'll fund construction on it.

Most Hillsborough construction loans come from local banks or specialized jumbo lenders. They want to see licensed general contractors with bonding, not owner-builders.
Draw schedules get tied to inspection milestones. Expect 5-7 draws over the project, each requiring third-party verification before funds release.
I tell clients to add 40% to their timeline and 20% to their budget. Hillsborough's approval process is slow, and high-end finishes always cost more than the first estimate.
Lock your construction rate if possible, even at a premium. Projects here routinely stretch past initial timelines, and rate drift can wreck your budget if you're on a variable rate.
Bridge loans work for buying the lot while selling your current home, but you'll still need construction financing for the actual build. Some borrowers stack them sequentially.
Hard money covers shorter renovation timelines, but full custom builds need proper construction loans. The terms and draw structure matter more than slight rate differences.
Hillsborough requires design review for anything visible from the street. Lenders factor this into their timeline assumptions — it's not negotiable.
Many lots here have geotechnical or environmental constraints. Lenders want those reports before committing to fund. Expect surveys, soil tests, and drainage plans.
Plan for 45-60 days once you have final plans and contractor bids. Lenders scrutinize timelines closely given local permit complexity.
Most lenders require licensed, bonded contractors for projects this size. Owner-builder setups get rejected unless you have documented construction experience.
You fund overruns from reserves or bring new cash. Lenders won't increase the loan mid-project without full re-underwriting.
Most are construction-to-perm loans that convert at completion. You get one closing, one set of fees, avoiding the hassle of refinancing into permanent financing.
Expect lenders to want $500K-700K in liquid reserves beyond your down payment. They want certainty you can finish the project through delays.
