Why Marina Homeowners Choose Peninsula Construction

Marina is one of Monterey County's most exciting housing markets. With ongoing development at former Fort Ord and a growing young professional population, Marina's rental demand is strong and rising. ADU investors in Marina are getting in early on a community with serious upside.

Marina lots tend to be newer, more uniform, and often well-suited for ADU construction without the complications of older foundation work. Peninsula Construction's experience in both new construction and retrofit ADUs means we can build efficiently on Marina properties.

LOCAL KNOWLEDGE

Marina has adopted California's state ADU regulations, making it straightforward to permit an ADU on most residential lots. The city's newer infrastructure and relatively newer housing stock means fewer unexpected costs during construction — great news for investors watching their budget.

Every Type of ADU, Done Right

Peninsula Construction builds all five ADU types in Marina. We'll help you determine which type maximizes your property's potential.

🏠

Detached ADU

A fully separate structure in your backyard. Maximum privacy and rental value. Custom designed to your lot.

🏡

Attached ADU

Connected to your main home but with a separate entrance. Cost-effective with shared wall construction.

🏢

Garage Conversion

The most affordable ADU path. We convert your existing garage into a fully permitted living space.

🚪

Junior ADU (JADU)

Up to 500 sq ft carved out of your existing home. Lower cost, faster permits, great for in-law suites.
