San Diego builders rarely struggle to find renters or buyers. The hard parts are land that costs more than the building in some neighborhoods, permit reviews that can stretch for months, and a refinance that has to work on rent, not on the value the project creates.
In short: Our top pick for San Diego ground-up construction is LendingStreet. We finance investor builds of 1 to 8 units, from infill duplexes and lots with ADUs to spec homes and build-to-rent projects, sized on loan-to-cost with terms set per project. Draws are released after inspections, LLC borrowers are standard, and when the build is done we can refinance it into a 30-year DSCR loan qualified on rent with no W-2s or tax returns.

LendingStreet is built for investors, and our construction program covers the projects San Diego builders actually take on: a new duplex on a single-family lot, a main home with detached ADUs, a spec house in a coastal or inland neighborhood, or a small 5-8 unit building near transit.
Each loan is sized on loan-to-cost and structured around your plans, permits, budget and builder experience. Money for the build arrives in draws after inspections, so the schedule follows real progress on site. Because we also make DSCR rental loans, the finished property can move into long-term financing without starting over with a new lender.
If you have a lot under contract or plans in review with the city, send the details through the form below or call (877) 298-1001 and we will size the project with you.
Most investor construction in the city happens on infill lots rather than raw land. Older post-war neighborhoods such as City Heights, Encanto, Clairemont, Logan Heights, North Park and Normal Heights have single-story homes on lots large enough for a second structure or a full rebuild as a duplex.
Across the county, Chula Vista, National City, Lemon Grove, Spring Valley, El Cajon, Escondido, Vista and Oceanside offer somewhat lower land prices and more room for detached units. Hillside and canyon-edge parcels show up often, and they bring grading, retaining wall and fire-hardening costs that need to be in the budget from day one.
Because land is expensive, many builds pencil only when the lot carries more than one unit.
In the city, building permits run through the Development Services Department. Review time varies with project size and submittal quality, so budget for it. Other cities and unincorporated areas run their own departments.
California has widened what can be built on single-family lots through ADU laws and SB 9, and San Diego has revised its own ADU rules more than once in recent years. Some of these programs carry conditions that matter for investors, so confirm the current version for your parcel before you finalize plans.
Lots inside the Coastal Overlay Zone may need a coastal development permit as well. Parcels near open space can fall in fire hazard areas with extra construction standards, and development impact and utility fees can be significant.
Here is how LendingStreet lines up against the types of lenders San Diego builders usually talk to. Terms at banks and private lenders vary, so treat the other columns as general patterns.
| What builders need | LendingStreet | Typical local bank | Typical hard money lender |
|---|---|---|---|
| Focus | Built for investors building 1-8 unit rentals and spec homes | Often favors existing customers with deposits | Short-term deals of many kinds |
| How the loan is sized | Loan-to-cost, with terms set per project | Often lower leverage plus a full personal financial review | Varies by lender |
| Multi-unit infill on one lot | Yes, duplexes, ADU projects and 5-8 unit buildings | Varies; may limit unit count | Varies |
| What gets reviewed | Plans, permits, budget and builder experience | Often tax returns, financial statements and liquidity | Varies; often the deal and the lot |
| Borrowing entity | LLC borrowers are standard | Varies by bank | Usually allowed |
| Draws | Released after inspections on a set schedule | Varies; may run through internal review | Varies by lender |
| After the build | Refinance into a 30-year DSCR loan qualified on rent | Usually a separate loan with income documents | Usually no long-term option |
| Where they lend | All 50 states and DC | Usually a local footprint | Usually local or regional |
This example is illustrative and not a quote.
An investor buys an infill lot in an older inland neighborhood for $700,000 and plans a new duplex plus a detached ADU. Hard costs are budgeted at $1,050,000 and soft costs (design, engineering, permits and impact fees) at $190,000, for a total project cost of $1,940,000. For this illustration, the loan is sized at 70% of cost, or $1,358,000, so the investor brings $582,000. Hard costs are released in about 5 draws of roughly $210,000 each as inspections confirm progress.
At completion the three units are valued at $2,450,000 and lease for $4,200, $4,200 and $2,600, or $11,000 a month. Refinancing the full $1,358,000 would leave the DSCR near 0.92x, below the 1.0x standard. Paying the balance down by $228,000 to a $1,130,000 DSCR loan (about 46.1% of value) gives estimated principal and interest of $7,613, estimated taxes of $2,409 and insurance of $433, a total of $10,455 and a DSCR of about 1.05x.
Under Proposition 13, new construction is reassessed when it is completed, so the tax bill on a finished build reflects the new improvements rather than the old house. Base levies run near 1% of assessed value, and local bonds and special assessments add to that; use the full combined figure in your rental math and confirm it with the county.
California counties charge a documentary transfer tax on sales, and some cities add their own. Insurance in fire-exposed areas has become harder to place, so get a quote early.
If short-term rental income is part of the plan, note that the City of San Diego licenses whole-home short-term rentals and caps how many licenses it issues. A long-term lease is the safer basis for refinance math.
Ask every lender the same questions so the answers line up side by side:
LendingStreet's answers: loans are sized on loan-to-cost with terms set per project, and leverage can be lower on larger balances or 5-8 units, which varies by program. Draws follow inspections on a schedule agreed before closing. We look for builder experience or an experienced general contractor, LLC borrowers are standard, and the finished rental can refinance into a DSCR loan with a 1.0x standard minimum, rate-and-term up to 80% LTV on some programs and seasoning that varies by program.
Strong files have approved or nearly approved plans, a detailed line-item budget with a contingency, a builder with completed projects of similar size, and an exit that works at today's rents or sale prices. Projects without plans or permits, or a borrower with no build track record and no experienced general contractor, usually do not qualify.
Projects of 9 or more units are commercial and run through our commercial lending team instead. For 1-8 unit builds in San Diego County, get a quote with the form below or call (877) 298-1001.
Our top pick is LendingStreet. We are built for investors, size construction loans on loan-to-cost with terms set per project, release draws after inspections, lend to LLCs and can refinance the finished rental into a 30-year DSCR loan, so one lender can carry the project from lot to long-term hold.
Yes. We lend throughout San Diego and San Diego County, and in all 50 states and DC, on non-owner-occupied investment property.
Yes, if the zoning and permits allow it. We finance 1-8 unit investor builds, including multiple units on one lot. Confirm your parcel's eligibility under current state and city rules before you finalize plans.
It affects the timeline. If your lot needs coastal review, plan for it in the schedule and holding budget. We generally want the required approvals in place, or close to it, before the build is funded.
The construction budget is released in stages. After each stage is finished, an inspection confirms the work and the draw is funded. Our draw schedule calculator shows how a budget breaks into stages.
Yes. The finished rental can qualify on its rent with no W-2s or tax returns. The standard minimum DSCR is 1.0x, and seasoning varies by program.
Builder experience matters. A borrower with no track record usually needs an experienced general contractor on the project to qualify.
