The Project
A coastal infill triplex in Pacific Beach.
3901-3905 Haines St is a newly built, three-unit residence in the Crown Point pocket of Pacific Beach, just two and a half blocks from Sail Bay. Inabnet placed the construction financing for this project. — part of the capital and development work Inabnet does across San Diego.
Designed by Scot Frontis, AIA, with interiors by Sol Quintana Design, the property combines a two-bedroom primary residence, a fully separate two-bedroom ADU, and a permitted one-bedroom sleeping unit within a single detached structure. It's one of three sibling properties built together on Haines Street as the Crown Point Coastal Collection.
For Inabnet, it's a look at the kind of ground-up coastal infill work happening in San Diego right now — and the financing relationships that help projects like it get built.

The Opportunity
Coastal infill, limited supply
Pacific Beach is one of San Diego's tightest coastal submarkets — small lots, high demand, and very little available land for new construction. Projects like 3901-3905 Haines St depend on the right site, the right design, and the right capital coming together.
- A 6,141 sq ft coastal lot, two and a half blocks from Sail Bay
- Three separate living configurations within one structure
- No shared party walls with neighboring residences
- Built to a for-sale coastal standard from day one

Why It Matters
Presence across San Diego's coastal market
Sophisticated coastal infill projects need financing partners who understand the market as well as the site plan. 3901-3905 Haines St reflects that kind of involvement.
Inabnet was involved in the financing side of this project — one part of the broader work Inabnet does across San Diego, spanning construction, development, and capital support for ground-up residential projects.
For a market as tight as Pacific Beach, being part of how a project gets financed is as meaningful as being part of how it gets built.
What this reflects
- Involvement across multiple stages of a project's life, not just construction
- Familiarity with the financing side of coastal infill development
- A presence in Pacific Beach and the greater San Diego market
- Part of Inabnet's broader portfolio across San Diego, Tampa, and Austin
