General Contractor in Westminster, CA

Which Westminster rules change a re-roof, a fence, a patio or an ADU on a 1960s lot?

Westminster began as a church project. Rev. Lemuel Webber founded it in 1870 as a Presbyterian temperance colony, and for decades the land grew dairy feed, walnuts, strawberries, celery and lima beans, later sugar beets, and even goldfish. Growth stalled through the Depression, the 1933 earthquake and a bad flood in 1938. The city incorporated in 1957 with 10,755 residents under the name Tri City, a plan to join Westminster, Barber City and Midway City. Midway City stayed out, Barber City came in, and voters restored the Westminster name five months later. Housing followed the late boom. Census Bureau estimates for 2024 put 29.6 percent of homes in the 1960s and 24.5 percent in the 1970s, about 74.5 percent before 1980 and exactly half before 1970. Those counts carry wide margins of error, so read them as a pattern, not a precise tally. The pattern is plain enough: your house is probably 50 to 65 years old, on a small lot, and 45.8 percent of occupied homes are rented. That age points toward lead-safe repainting and window replacement, old plumbing and wiring behind a kitchen remodel or bathroom remodel, and original flooring over adhesives nobody has tested.

What sets Westminster apart is the City's own code, read from the GoCodebook mirror because the City site and every official code host answered our tools with a 403 error. Confirm each point with the City before you sign anything. The local roof amendment calls for at least Class B covering on any repair, alteration or partial replacement, so even a patch needs a rated material, and our roofing page explains why. Whether a straight tear-off and replacement needs a permit is unconfirmed, and so is fire zone status for any Westminster parcel, so look up yours on CAL FIRE's viewer. A fence tops out at 3 feet inside the front setback and 6 feet along R1 side and rear lines. The permit exemption list mentions a 4 foot height for masonry walls or fences, yet its wording leaves open whether wood is included. Driveways and walkways may cover only 50 to 75 percent of a front yard, depending on lot width, which governs any concrete job. An attached patio cover must stay 10 feet from the rear lot line and 5 feet from a side line, and big detached structures face their own caps, which frames deck and patio plans.

Growing the house has its own limits. A legal nonconforming single-family home can expand only 20 percent cumulatively, so a room addition must meet today's setbacks even if the old house does not. A house gets one kitchen unless an ADU adds a second, and the code bars a kitchen or wet bar upstairs. The ADU section on the mirror, 17.400.135, approves projects ministerially in 60 days, or 30 on a pre-approved plan, and it sets 1,200 square feet for a detached unit. We did not read its subsection N, and the State HCD wrote the City in March 2023 about an earlier ordinance, so confirm which version governs before you design an ADU. Repainting an old house is a lead question first, and our painting guide covers the EPA rule.

Permits run through the City's Building Division, and we state no City hours, phone numbers or fees, because we could not read them. The mirror shows the 2025 California codes adopted by Ordinances 2626 and 2629, a Zoning Clearance step ahead of building plan check, and Orange County Fire Authority as the fire reviewer. One rule surprises owners: a permit expires on a change of contractor if the work is unfinished, and a new one is needed to complete it. MDG Builders is a licensed general contractor, CSLB #1040337. Our role is to write the scope, shepherd the plans and permits and sequence the crews. Licensed specialty subcontractors build the work, and any of them will owe you a license number and a certificate of insurance on request. Our posts on how general contractors use subcontractors and checking a contractor license cover the details. Neighbors with their own pages are Garden Grove, Huntington Beach and Santa Ana. Fountain Valley, Seal Beach and Stanton have no page yet, so call us about work there.
