Where an ADU fits on a Manhattan Beach lot
Manhattan Beach lots are rarely generous, so the first ADU question is where the unit can physically go. On a narrow Sand Section parcel, the realistic spot is usually at the alley, building above, beside or in place of the garage. On the larger lots of the Tree Section and East Manhattan Beach, a detached backyard unit or an attached unit off the main house may also work.
California’s ADU laws have opened many more lots to a second unit, but the city still reviews setbacks, height, utilities and fire access, and lots near the beach may need coastal review as well. We have not published an ADU project in Manhattan Beach yet: the closest ADU and garage conversion project in our gallery is in Torrance, pictured here, and our work inside the city so far has been interior remodeling, such as this bathroom remodel.
How we take an ADU from first sketch to final inspection
Every ADU we take on follows the same path, and the order matters. First we look at the lot: its size, the setbacks, where water, sewer and power can connect, how crews and materials will reach the back of the property, and whether the coastal zone applies. Then our design arm, Arch by DYM, draws the unit and prepares the plans for the city.
Once the plans are approved and permits are issued, our in-house crews build the unit and the city inspects it at each stage until it is signed off. On a Manhattan Beach lot much of that work happens a few feet from the neighbors and the alley, so delivery times, staging and the order of the work are agreed before construction begins. You can read more about how we approach units of every size on our ADU contractor page.
ADU, garage conversion or a larger remodel?
An ADU is not the only way to add living space. If a sound garage already stands on the lot, a garage conversion in Manhattan Beach may give you the same room for less new construction. If the main house needs work too, a complete home remodel can include the new space in one project. Our Manhattan Beach page covers everything else we do in the city.
The choice usually comes down to three things: whether the garage is worth keeping, whether you need a fully separate unit with its own kitchen and entrance, and how much of the main house also needs attention. We look at all three during the lot review. Our ADU service also covers neighboring cities, each with its own rules: see Redondo Beach, Santa Monica and Pasadena.

Frequently Asked Questions
Is a small Manhattan Beach lot big enough for an ADU?
Often, yes. State law allows ADUs on most residential lots, and on small parcels the answer is usually a unit at the alley or over the garage. Whether yours qualifies depends on setbacks, height and utilities, which we check before any design work starts.
Does an ADU near the beach need coastal approval?
It can. Part of Manhattan Beach lies in the California coastal zone, and new construction there may need coastal review in addition to the building permit. We confirm whether your address is affected during the lot review so the schedule accounts for it.
Can family live in the ADU, or can I rent it out?
Both are common uses. Many owners build an ADU so a parent or grown child can live close by, and long-term rental is another frequent reason. Short-term rental is another matter: it is restricted, and we would check the rules for your address before you plan around it.
Who designs the ADU, and who builds it?
The design and permit drawings come from Arch by DYM, the design firm that works with DYM, and DYM Builders Group builds the unit with in-house crews. Because both sides work together from the start, the unit is designed around how it will actually be built.
