New Construction in Pasadena
Cedarline Design Build plans new Pasadena houses with ember-resistant exteriors where the lot calls for them, and an ADU worked into the site plan.
Stone veneer set over cement board takes bright sun, rinses clean after dry wind and does not ignite from a drifting ember. For a new Pasadena house that last quality carries weight, because some Pasadena lots are covered by mapped fire hazard zones, where ember resistance is a code requirement. A matching finish on an ADU at the back of the lot ties both buildings together.
Choosing the exterior skin
Cladding is chosen together with the roof, vents and eave details, because embers find gaps. The veneer sits over cement board, which does not burn, and attic and crawlspace vents are specified with fine metal screens. Mortar joints and stone edges are detailed to shed water, and flashing at windows and the base of the wall goes in before any stone is set. The same palette can wrap an ADU, so a secondary building does not become the weak point in the lot's fire planning.
Pasadena plan review and fire rules
Pasadena's building department reviews new houses, and a lot covered by the fire hazard maps picks up ignition-resistant construction requirements on top of the usual structural and energy review. The reviewer wants wall assemblies, vent details and roof classification written on the plans, so we draw them in from the start. Defensible space and the placement of an ADU relative to the main house are considered together, since both buildings count against the same lot. Roof assemblies and eave ratings are listed by product, which keeps substitutions during construction from reopening the review.
New Construction in Pasadena: common questions
Ask early. If the parcel falls under the fire hazard maps, the separation between house and unit, and the materials on both, affect the ember-resistance review. Putting both on one drawing set lets the reviewer see the whole lot, and municipal ADU rules still decide whether a unit is allowed.
Expect a survey, a soils investigation and a check of the parcel against fire hazard maps. Design and engineering follow through our consultants, then the building department review. Old structures come down only after utility disconnects and a permit. Ground breaks once approved plans are in hand.
On a lot covered by the fire hazard maps, the wildfire provisions of the building code govern roofing, venting and exterior walls. Everywhere in the city, zoning limits how tall the building may be and where it sits, and the energy and green standards shape the envelope. Stormwater and grading requirements govern the earthwork.
