Who We Are

A Remodeling Partner For Simi Valley

Simi Valley grew fast. The first tracts went up in the late 1950s, whole neighborhoods followed through the 1960s and 1970s, and planned communities like Wood Ranch filled the western hills in the 1980s. That leaves a city full of well built houses that are now forty to sixty years old. Home remodeling in Simi Valley usually means respecting a sound tract layout while bringing the kitchen, baths and systems into this century.

Construction by Maya is a women led design build studio with its office on Park Granada in Calabasas, an easy drive over to the 118 corridor. Our team designs the project with you, prepares plans for the City of Simi Valley, and builds it with our own project management. You deal with one company and one schedule, and you see the price in writing before any demolition starts.

  • Tract homes made current with better kitchen flow, larger showers and wiring that can carry modern appliances.
  • Room to grow through garage conversions, backyard ADUs and single story additions on established lots.
  • Permits through the city since Simi Valley runs its own Building and Safety Division, separate from Los Angeles and the county.

Why Us

Why Simi Valley Families Hire Maya

A house in the Presidential Tract and a hillside home in Wood Ranch need different plans. We start from your property and your household, not from a template.

01

Women Led Studio

Founder Hila Hemo built a company where design and construction answer to the same people, so details survive from drawing to finish.

02

Licensed And Insured

California general contractor license #1034501, with general liability and workers comp on every Simi Valley project.

03

Close To The 118

Our Calabasas office is a reasonable drive away, so we can meet on site, review selections and respond quickly during the build.

04

Clear Written Pricing

You receive an itemized scope and a realistic schedule up front, and changes are priced in writing before they happen.

05

City Of Simi Valley Permits

We prepare the drawings, submit through the city's online portal and coordinate inspections, plus any HOA review your tract requires.

06

Small Project Load

We take on a limited number of homes at a time, so your project gets real attention rather than a rotating crew.

Know Your House

Tract Homes With A Second Act In Simi Valley

Most Simi Valley homes came out of large tracts, which is good news for remodeling. Floor plans repeat, slab foundations are common, and the structure is usually straightforward to work with. The challenges are predictable too: original copper or galvanized lines that are nearing the end of their life, electrical panels sized for a smaller household, single pane windows on west facing walls, and kitchens closed off from the family room.

Many neighborhoods also come with a homeowners association. Wood Ranch, Bridle Path and Long Canyon all have associations, and many of them review exterior changes such as additions, patio covers and new windows. Homes that back up to the Simi Hills or the Santa Susana foothills can face fire zone construction standards as well. We look at all of this before design starts, so your plan clears the city and the HOA the first time.

  • HOA review built into the schedule with drawings prepared for both the association and the city.
  • Foundation and soils checks before we plan any addition, second story or detached ADU.
  • Fire exposure reviewed early for lots that sit against open space and hillside brush.

Possibilities

Ideas For Your Simi Valley Home

Many owners here love their street and their schools and would rather improve the house than move. A remodel can open the kitchen to the family room, turn the hall bath into something you enjoy, or put a legal rental unit in the backyard. Home remodeling in Simi Valley is often the most practical way to get the house you want without leaving the neighborhood.

  • Open the kitchen to the family room
  • Convert the garage into an ADU
  • Add a ground floor primary suite
  • Swap the tub for a walk in shower
  • Replace old pipes and the panel
  • Shade the patio for summer

FAQ

Simi Valley Remodeling Questions

Straight answers to what Simi Valley homeowners ask before they commit to a remodel, addition or ADU.

Who issues building permits in Simi Valley?

The City of Simi Valley does, through its Building and Safety Division. Some small pockets at the edge of town are unincorporated Ventura County, so we confirm the jurisdiction for your address first.

Will my HOA need to approve the work?

If your home is in an association, exterior changes such as additions, patio covers, windows and ADUs usually need its review. Interior remodels often do not, but we check your CC&Rs.

Can I add an ADU to a Simi Valley tract lot?

Often, yes. Garage conversions and junior ADUs fit many lots, and detached units work where setbacks and utilities allow. The city has been updating its ADU standards, so we confirm current rules for your parcel.

Is my 1960s or 1970s home worth remodeling?

Usually. Tract homes from that era tend to have simple structure and repeatable plans. The money goes into layout, systems and finishes rather than fixing unusual construction.

Do you handle hillside or fire zone lots?

Yes. Homes near open space can face fire resistant construction standards and may need soils or grading review. We account for both in the design and the budget.
