Where we work in National City
National City is one of the county's older cities, with a large commercial and industrial base on the bay. Old Town and the Westside are inside the service area, and so are the Mile of Cars, Plaza Bonita and Olivewood Gardens. Lincoln Acres is an unincorporated pocket surrounded by the city rather than part of it, and because the service area is county-wide it is covered either way. National City ZIP codes covered include 91950.
Commercial scope is written into all four of our trades. Air conditioning covers commercial and residential, electrical covers residential and commercial, and construction covers commercial buildouts and tenant improvements alongside home remodeling. All four sit under one CSLB license, #1028305, held by MKA Services Inc dba American Construction, which carries the B, C-36, C-10 and C-20 classifications.
On the air conditioning side, ductwork modifications sit in the same scope as installation, troubleshooting, repairs, maintenance and removals, for all AC systems including mini splits. So a system change and the distribution that goes with it are one piece of work rather than a handoff between two companies.
That is the shape of the whole operation. A crew of 10 including the four owners, one owner leading each trade, so a National City buildout that needs construction, electrical and air conditioning is one company working to one schedule.
What the one license covers
MKA Services Inc dba American Construction holds CSLB license #1028305, issued June 2017, and the license carries four classifications. Each one maps to a trade, and each trade is led by the owner who holds it:
- B, general building. Commercial buildouts and tenant improvements, whole-home renovations and additions, structural modifications and open-concept conversions, framing and structural reinforcements, garage conversions and extensions, accessory dwelling units (ADUs), and custom home building.
- C-36, plumbing. Water heater installation, standard and tankless, hot and cold water repairs, reroutes and new construction, drain cabling, hydro jetting and drain descaling, pressure regulators, mixing valves and backflow installation, and underground gas line installation, repair, reroute and leak detection.
- C-10, electrical. Main service panel and subpanel upgrades, lighting and wiring upgrades, new construction and remodel wiring, electric vehicle chargers, and troubleshooting, diagnostic, service and repairs, residential and commercial.
- C-20, HVAC. All AC systems including mini splits, commercial and residential, covering installation, troubleshooting, repairs, ductwork modifications, maintenance and removals.
Work on the commercial side
National City has a large commercial and industrial base on the bay, and all of it is inside the service area. As a general matter of the trade, a tenant improvement rarely stays inside one trade: a change of use changes the lighting and the power draw and the cooling load as well as the walls. Commercial buildouts and tenant improvements are general building work under the B classification, and the electrical and air conditioning that come with them are covered under C-10 and C-20 on the same license rather than by a second company.
Work on the residential side
The residential scope in National City is the same four trades. Luxury kitchen and bathroom remodeling, flooring installation and refinishing, high-end custom cabinetry and millwork, and decking and waterproof deck systems on the construction side. Water heater installation, standard and tankless, bathtub and shower installation and removal, and drain cabling, hydro jetting and drain descaling on the plumbing side. Lighting and wiring upgrades and electric vehicle chargers on the electrical side. Old Town and the Westside are inside the service area, as is the rest of the city.
Looking up an electrician or a contractor near you
A search for an electrician near me in National City ends at a license number, and that number is #1028305. Sitting under it are electric vehicle chargers and lighting and wiring upgrades, commercial and residential AC repairs, drain cabling, hydro jetting and drain descaling, and commercial buildouts and tenant improvements. The service area does not stop at the city line, so electrical work in Chula Vista and general construction in San Diego run off that same license and the same crew of 10.
How an estimate starts here

Yes. Whole-home renovations and additions, structural modifications and open-concept conversions, and framing and structural reinforcements are all part of our construction work, alongside single-room kitchen and bathroom remodeling.
