Acerca de
Willowside Road crosses the flat farm country between Santa Rosa and Sebastopol, where vineyard rows, horse paddocks and older ranch houses sit a few minutes from the city's western subdivisions. Cortez Associates, owned by Carmen Cortez, is listed at 1495 Willowside Road, and directory listings file it under architecture and professional services. Everything on this page was assembled from public business records, and the owner has not yet confirmed it.
What an architectural office in Santa Rosa usually handles
A business of this kind usually takes a project from a rough idea to a set of drawings the building department will accept. In Sonoma County that often means home additions, kitchen and bath reconfigurations, accessory dwelling units on larger lots, and small commercial tenant improvements. Since the 2017 and 2020 fires, rebuild plans for homes lost in Coffey Park, Fountaingrove and the hills east of town have been a steady part of the work for design offices around Santa Rosa.
The usual sequence runs from a site visit and measurements to schematic sketches, then design development, construction documents and a permit submittal. Some offices stay involved during construction to answer the builder's questions; others hand over the drawings and step back. Which model Cortez Associates follows is a fair thing to ask on the first call.
Before you sign a design agreement
Ask who will stamp the drawings. In California the title of architect is reserved for people holding an architect's licence, and some projects need an architect's or engineer's stamp, so ask for the number and look it up with the California Architects Board. Ask how the fee is set: a percentage of construction cost, an hourly rate with a cap, or a fixed sum per phase. Get a written agreement listing the phases, the revision rounds included and who owns the drawings afterward. Have a property survey, any old permits and a rough budget ready, because those three things shape every early decision.
Where the work goes
From Willowside Road it is a short drive into Santa Rosa proper and west to Sebastopol, Graton and Forestville. Windsor, Fulton, Rohnert Park and Healdsburg fall within an easy radius, and the rest of Sonoma County is reachable for site visits. Parcels outside city limits are reviewed by Permit Sonoma rather than the City of Santa Rosa, which changes the paperwork and the timeline.
The phone number on file is 707-566-9954. If you are Carmen Cortez, the chamber can help you claim this listing and correct anything above; a single call starts it.

Preguntas frecuentes
Típico de este tipo de negocioDo I need an architect for a home addition in Sonoma County?
Not always. California lets unlicensed designers draw many single-family projects, but some structural and commercial work must be stamped by an architect or engineer. Ask the city or Permit Sonoma what your project needs before hiring.
How are architectural fees usually charged?
Common arrangements are a percentage of construction cost, an hourly rate with a cap, or a fixed fee for each phase. Whatever the method, get it in a written agreement that also lists what is not included, such as engineering or surveys.
What should I bring to a first meeting?
A property survey or parcel map if you have one, copies of earlier permits, photos of the existing space, a wish list and a realistic budget. Those details let a designer tell you quickly whether the project is feasible.
How long does a permit take in Santa Rosa?
It depends on the project and the season. A small remodel can clear plan check in weeks, while an addition or new house may take several months with revisions. Ask the designer for a timeline based on recent projects.
