Adding an ADU in Reseda usually costs between $180,000 and $320,000 for a detached unit, with garage conversions running $120,000 to $220,000. Those ranges shift based on one thing most other Valley neighborhoods don’t deal with: Reseda’s particular mix of mid-century ranches, large lots, and a long history of unpermitted garage conversions that need legalizing before new construction can begin. Call (661) 362-8059 and we’ll walk you through what applies to your property.
Why Reseda Homes Are Different
Most Reseda homes were built between the 1940s and 1960s as single-family ranches on generous 5,000+ square foot R1 lots. That’s good news for ADU feasibility. The challenge sits underneath: original foundations, aging electrical panels, and roof structures that were never designed to carry the load of an attached addition or a second story. We regularly see 100-amp panels that need upgrading to 200 amps before an ADU can pass inspection, and slab foundations that require a soils report before we pour anything new.
Then there’s the climate. Reseda summers routinely pass 100°F, and a poorly insulated ADU becomes an oven by mid-July. Title 24 energy compliance isn’t a box we check at the end; it shapes the wall assembly, the window placement, and the HVAC sizing from the first drawing. Winter nights near freezing mean the same walls have to hold heat, not just shed it. The houses here also share something you won’t find in newer Valley developments: decades of unpermitted rear garage conversions, what local designers sometimes call bootlegged units. Many Reseda ADU projects start with amnesty paperwork to legalize that existing space before we file for anything new. It’s a Valley-specific wrinkle, and Reseda has more of it than most.
Our Main Reseda Services
Three kinds of projects keep our Reseda crews busy, and each has its own dedicated page with pricing and permit detail.
Home Addition Contractor in Reseda
Home additions in Reseda usually mean extending a mid-century ranch outward, which puts the existing roofline and foundation in the conversation from day one. We match the new roofline to the old one, tie the new slab to the existing footing, and upgrade the panel if the added square footage demands it. Many Reseda additions also involve quiet hours around school schedules and keeping dust out of the lived-in side of the house. Home Addition Contractor in Reseda covers the full scope and what to expect for your street.
Garage Conversion Contractor in Reseda
Garage conversions in Reseda carry a local twist: a surprising number of garages here were partially converted years ago without permits. Before we frame a single wall, we check what the city has on file and what needs to be brought to code. Attached garages from the 1950s and 60s often need new footings, insulation, and electrical before they become legal living space. The finished unit still has to meet ADU setback and parking rules. Garage Conversion Contractor in Reseda walks through the whole process, including the amnesty path when applicable.
ADU Builders in Reseda
Detached ADUs work well on Reseda’s larger lots, where a rear-yard unit leaves the main house and driveway untouched. The lots here are deep enough for a two-bedroom unit with a small porch, and the state’s lot-split law opens more options for homeowners with a big enough parcel. We handle the site plan, the utility trenching, and the Title 24 package, and we bring prefab options to the table when the lot conditions favor them. ADU Builders in Reseda has the full breakdown by unit size and configuration.

What pushes Reseda prices up is usually the age of the house: original 1950s electrical, a foundation that needs reinforcement, or an unpermitted rear structure that has to be brought to code before the new unit can be permitted. Every project we quote in Reseda gets a written price before work starts, and that’s the price you pay. No change orders appear after the crew arrives unless you ask for a change yourself.

Most Reseda homes get a site visit within three to five business days of the initial call. We schedule in half-day windows and call ahead the morning we’re coming. The estimate itself follows about a week later with the full written line items.
If the existing unpermitted living space is on the same lot, yes, it has to be brought to code or removed before the city will issue permits for a new unit. We help file the necessary paperwork and include the cost in your written estimate. Call (661) 362-8059 to talk through your specific lot.
It will if the insulation and HVAC are under-specified. We size cooling for actual Valley summer conditions and use wall assemblies that meet or exceed Title 24, so the unit holds comfortable temperatures without running the AC constantly. Ventilation matters just as much, especially in a converted garage.
