How does an ADU in San Fernando tie into an older main house's utilities?

We trace power, water and sewer from the street to the house before any design. The panel is opened and rated, the sewer is scoped and water pressure is tested where the unit will sit. If the old services can carry the added kitchen and bath, the ADU ties in through new branches. If they cannot, upgrades are planned with the utility and the city.

Can an old detached garage in San Fernando become an ADU?

Often, yes. An older garage may have a thin slab, no footing at the edges and walls without anchor bolts, and we check each of those. If the slab and framing can be brought up to code, converting keeps the footprint and the setbacks the garage already has. If not, a new unit is the cleaner path, and the reasons are given in writing.

How do you make an ADU in San Fernando match the main house?

The match starts with the stucco texture and color, sampled from the main house. Next are the roof slope and material, the eave depth and the window style. If the house has a tile roof or arched openings, the ADU repeats them in a simpler form. Light fixtures, house numbers and door hardware are chosen to suit the main house as well.

Ask for a callback

Three-coat stucco over a proper weather barrier is a finish we can choose for a San Fernando ADU when the main house wears stucco too. On an inland lot it stands up to hard sun, dry wind and knocks from yard tools, and it can be troweled to match an older texture. Paired with a light-colored roof and dual-pane windows, it gives the unit the same face as the house in front of it.

Matching an older stucco finish

Old stucco textures run from smooth to heavy dash, and the color often comes from pigment mixed into the final coat. We take a sample from a hidden spot on the main house, mock up a small panel on the ADU wall and adjust the texture before the finish coat goes on. Weep screed at the base, flashing at each window and a drainage plane behind the stucco keep water from getting trapped. The new wall reads as original from the yard and can dry out after a hard rain.

Utilities and the San Fernando permit

The City of San Fernando reviews ADU plans through its own building division, and part of that review is the utility plan showing how the unit connects to power, water and sewer. On an older lot we check the panel, scope the sewer and test water pressure before that plan is drawn. If the main house needs an upgrade to carry the new load, the work is included in the same permit and priced in the same written scope, where the upgrade shows on a line of its own from the start.
