Home Addition Contractor in Ventura

Ask two questions before anyone draws. Was the house first permitted before or after March 15, 1965, the date that decides whether it must keep a two-car garage? Does it appear in the Historic Resources Survey the City Council adopted on July 14, 2026, which can send an addition to historic design review? A contractor who skips either draws a plan Permit Services will send back. Master Construction has been family owned since 1994 and builds additions across Ventura under Lic. #1027281, with design, concrete, electrical and plumbing on our own crews.

Type sets the base. A bump-out or ground-floor room addition buys footings, walls and a roof tie-in; a second-story addition adds engineering of the existing footings and walls, and the old roof comes off. Size is next, including whether new living space passes 500 sq ft and triggers school fees on the whole increase. Then come panel and utility upgrades, any garage space the 1965 parking rule requires, coastal or historic review where the lot calls for it, fire sprinklers if the city fire department requires them, energy code items such as a heat pump, and finishes. We start with a site walk and finish with a written fixed-price scope.

It runs in two halves. The permit half is design and engineering, then plan check at Permit Services, then corrections; plan check time varies by desk and season, and the counter is closed Fridays. A coastal appeal-zone lot adds an Administrative CDP hearing noticed at least 10 days ahead, a 10-day window to appeal to City Council, and a 10-working-day Coastal Commission appeal window. A house on the historic survey may add a Historic Preservation Committee hearing. The build half follows the type, with a bump-out the shortest and a second story the longest. Both halves are dated in writing before you sign.

Usually not. SBMC 24.545.040(B)(1) exempts single-family and two-family properties from design review except historic design review, so a conforming R-1 addition goes from the Ventura OPS submittal straight to plan check against the zoning numbers: 35 percent coverage, 30 feet and two and one-half stories, and setbacks figured as percentages of lot depth and width. Historic review applies in or next to a Historic District overlay, on a landmark, or on a house identified as eligible in the survey adopted July 14, 2026. Coastal-zone lots also need a zoning clearance or a coastal permit.

Often, once the structure checks out. The R-1 zone allows 30 feet and two and one-half stories, and the chapter has no second-story design review, no daylight plane and no upper-window privacy rule. The limit is structural: an engineer reviews the existing footings and walls, and the addition may not leave the house less compliant than it was. On R-1-B beach lots any portion above 22 feet steps back another 10 feet behind the front setback line. In the coastal appeal zone, the Administrative CDP requires findings that the addition does not block public coastline views and fits the scale of the area.

Not always. Ventura's Coastal Zoning Code categorically excludes additions to one- and two-unit homes on lots that legally existed when the Local Coastal Program was certified in 1983, so additions outside the appeal zone need only a zoning clearance. The appeal zone runs between the sea and the first public road, within 300 feet of a beach, within 100 feet of a wetland or stream, and near a bluff top; the exclusion also stops on slopes over 20 percent. There an addition needs an Administrative Coastal Development Permit, decided by the director after a noticed hearing. The city's appeals maps show which side a lot is on.

Many families stay. A rear room addition or bump-out is built from outside, with the existing wall left closed until the new room is framed, roofed and dried in; the opening gets cut near the end. A second story is harder, since the old roof comes off over occupied rooms and the new stair lands somewhere inside. Some owners move out for that stretch. We schedule the loud and dusty work in blocks and keep a kitchen and a bath usable. Smoke and carbon monoxide alarms go up to current code through the whole house before the final inspection.

If your house is in a planned development or condominium community whose CC&Rs require approval, yes, and that review runs alongside the city permit rather than replacing it. Civil Code 4765 requires the association to decide in good faith, in writing and within the deadline in its own procedure; a denial must explain why and offer reconsideration at an open board meeting. CC&R height and second-story limits still stand under that statute. Tract housing zoned R-P-D also follows its planned development's own standards. We prepare one package for the board and Permit Services, and boards get the same written scope an owner does.

Decide by who will live there. An addition is part of the house: one kitchen, shared systems, and under SBMC 24.210.140 the city can require changes to doors, stairs or utility lines that would let it work as a separate unit. An ADU in Ventura gets its own kitchen and entrance and follows state ADU law instead of the R-1 addition rules. A parent who eats dinner with the family fits a primary suite addition. A tenant fits an ADU. Garage conversions belong on the ADU side here, because converting a required garage into a plain bedroom runs into the 1965 parking rule.
