Spanish Colonial restorations, Mid-Century glass walls, contemporary view homes. Lifetime install warranty, BHPD-cleared crews, every permit pulled by us. Quote in 48 hours.
Permit timelines, HOA review (in the Flats and Trousdale especially), and the architectural premium of doing a Spanish Colonial right.
Beverly Hills runs its own Building & Safety department — separate from LADBS — and the inspectors are stricter than anywhere else in our service area. Window replacements over five units in a single permit trigger a structural review; door reframes in any pre-1965 home require a historic-resource screening that takes 10–14 days. We've pulled 84 permits in this city; we know which plan-checker prefers what, and we file for the screening before you sign so it isn't a surprise.
About 60% of the homes south of Sunset are Spanish Colonial Revival from the 1920s and '30s — original steel casements, leaded glass, deep stucco reveals. Replacing those with vinyl is a $400K mistake on a $5M home. We default to Marvin Ultimate or Andersen E-Series in bronze-clad aluminum to match the original sightlines, with simulated divided lites and an interior wood profile that reads correct from inside the room.
North of Sunset — Trousdale, the Flats above Whittier — is a different building. Mid-Century post-and-beam with floor-to-ceiling glass, often single-pane. The job there is heat load and seismic compliance: Title 24 in zone 8, plus seismic anchoring on 9-foot lites that weigh 200+ lbs apiece. We use Marvin's Modern line or Western Window Systems for these, with structural mullions sized to the engineer's letter.
All 14 services are available across Beverly Hills — pricing reflects the local Title 24 inspector rigor, BHPD insurance, and parking/equipment access.
The Flats (between Santa Monica Blvd and Sunset, Doheny to Whittier): Mostly 1925–1945 Spanish Colonial and Mediterranean Revival. Original steel casements, often leaded glass. Restoration-grade work — we typically recommend Marvin Ultimate clad-wood with bronze exterior, full SDL.
Trousdale Estates (above Sunset, north of the gates): Almost all 1955–1975 Mid-Century post-and-beam. Glass walls 8–12 feet tall, structural mullions doing real work. Marvin Modern, Western Window Systems, occasionally Fleetwood for the steel-look profiles. HOA architectural review adds 12 days on average.
Beverly Hills Post Office (90210 hillside above Beverly): Mixed eras — Spanish hillside, Mid-Century pole homes, contemporary new builds. Structural and Title 24 are the variables; HOA review is rare here compared to Trousdale.
Beverlywood (south of Olympic, west of Robertson): Tract Spanish from the 1940s, smaller windows, more frequent retrofit work. Milgard Tuscany or Andersen 100-series usually fits the budget and the aesthetic. Beverlywood is technically City of LA (LADBS jurisdiction), not Beverly Hills — we flag this on the walk-through.
North Beverly Drive and the Canon Drive corridor: Post-war transitional homes built in the late 1940s–early 1950s that blur between Spanish Colonial and traditional ranch. Many have been significantly remodeled; original window openings may have been altered. We verify rough opening dimensions and structural conditions before specifying on any remodeled post-war home in this zone.
We had three contractors decline our 1928 Spanish on the basis that it was 'too historic.' Red Stag's foreman walked the house, identified every original steel casement worth saving, and replaced only what was past restoring. The new bronze-clad units look factory-correct. Permit cleared first try.
Trousdale post-and-beam, six 9-foot lites facing the canyon. Two estimators told me it couldn't be done without changing the structural mullion line. Theo's crew engineered a new mullion that matched the original rhythm to the millimeter. Title 24, seismic letter, HOA — all handled.
We were the third owner of a Mid-Century in the Flats. Every window had been replaced badly twice. Red Stag pulled everything, fixed the rough-opening rot we knew about and the seismic-anchor problem we didn't, and brought it to current code. Two weeks, no rework, every receipt itemized.
Beverly Hills operates one of the most meticulous independent building departments in our service area — separate from LADBS, with its own inspectors, its own plan check staff, and fee schedules that run 40–80% above LADBS rates. The premium is real and it reflects the higher service level: inspectors are thorough, permit packages are reviewed carefully, and day-of inspections are required in some instances that LADBS handles differently.
The housing stock is almost entirely custom — Spanish Colonial, Mediterranean, and French Norman estates on the Flats, hillside contemporaries in Benedict and Coldwater Canyon, and a mix of post-war and new construction throughout. There's no tract housing in Beverly Hills. Project sizes tend to be larger (15–30 windows is not unusual on estate properties), specifications tend toward Marvin and Andersen at the top of their product lines, and access logistics are often complex (gated driveways, circular motor courts, staff scheduling around household calendars).
Architectural review for exterior alterations is handled through the Beverly Hills Planning Department for properties in historic overlay areas. Most window-for-window replacements don't trigger planning review unless the opening dimensions or exterior finish materials are changing significantly. We verify at permit intake and flag any review requirements before the project schedule is set.
Permits are processed by Beverly Hills Building and Safety. Residential window permits typically take 14–21 business days — plan accordingly for the extended permit timeline on estate scopes.
